---> Full show notes on HackMD  I, Degen - E17: OPSEC at DEVCON 6 - 10/06/2022Listen at: idegen.fmContact us: @idegenfmIntroWelcome to I, Degen - A podcast about crypto technology, security, and culture. With a healthy balance of enthusiasm and skepticism, we dig into a weekly look at crypto, cutting through the misinformation and hype in search of signal in the noise.Episode SummaryThis week we’ll do our usual weekly review of crypto security-related topics. We’re going to dig into the issue of conference OPSEC, or operational security, as we’re less than a week out from Ethereum’s flagship developer conference, and rumors swirl about security concerns in Bogota.I,Degen - Weekly ReviewSunday, October 2nd - Transit Swap Users Rocked for 21MTransit Swap has lost $21M to a vulnerability which allowed an unknown attacker to drain the wallets of users who had approved the protocol’s swap contracts.Leading up to Ethereum’s flagship developer conference being held in Bogota, Columbia next week, a wave of Tweets and some articles surfaced questioning the safety of conference goers. FUD or legit concern? Well dig more into this on deep dive in a few minutes.Office of the National Cyber Director Requests Your Insight and Expertise on Cyber Workforce, Training, and EducationOur Nation continues to face a significant shortfall in cyber talent, with estimates of approximately 700,000 open positions.October 1st, 2022 - No Digital Dollar Act Introduced - From Bitcoin.comU.S. Senator James Lankford (R-OK) announced Thursday that he has introduced a bill titled “No Digital Dollar Act to prohibit the U.S. Treasury and the Federal Reserve from interfering with Americans using paper currency if a digital currency is adopted and makes certain individuals can maintain privacy over their transactions using cash and coins.”October 4th, 2022 From Axios- Why Kim Kardashian got fined and Matt Damon didn’tKim Kardashian was fined $1.26 million Monday for touting crypto schemes — even as much more high-profile pitches from the likes of Matt Damon and Larry David have gone unpunished. The seeming double standard is a function of a subtle yet crucial distinction in securities law.Where Kardashian crossed the line was when she endorsed a crypto asset security.How it works: If you’re endorsing a company, the only rules that apply are the relatively lax ones from the FTC.If you’re shilling a security, then disclosing that you were paid — as Kardashian did with an #AD hashtag — is not enough; you also need to disclose how much you were paid.The bottom line: If you’re going to tout crypto, tout a crypto company, not a coin.Moving on… Usually, we focus on looking back at crypto security-related events of the previous week. I thought maybe we could also highlight any relevant upcoming events each week.I, Degen - Looking ForwardDevcon next week - There will be a keynote talk on the Nomad Bridge Hack. I think there will be a live stream if you are not attending.November 15th, PyChain - The First Virtual Event for Python and Blockchain DevelopersCall for speakers is openFree TicketsI, Degen - Deep DiveA wave of Tweets and some articles surfaced questioning the safety of conferencegoers leading up to Ethereum’s flagship developer conference in Bogota, Columbia, next week.Veteran Devcon attendees will remember a similar panic from previous events, including Devcon III in Cancun, Mexico, whereIs this FUD or a legit concern? Let’s dig in.Question: Is this a credible threat, in which there is a concentrated effort to target Devcon attendees, or is this FUD?If we follow the Tweets, the picture is unclear.This year Devcon security panic seems to have started with news outlets picking up a tweet from crypto_mackenna.However, it’s worth note the article in question doesn’t mention Crypto_McKenna follow-up Tweet reply on that same day which balances the original Tweet.Also, some sensational crypto influencer tweets that we’ll ignore. Mainly because they are purely opinion based, don’t provide any credible evidence of a threat, and are likely just ego-feeding clout farmers. I mention them because it is essential to understand and acknowledge that they play into the overall perception and conversation, even if they hold little substance and merit.Staying safe at Devcon in Bogota Twitter threads:- @lililashka-@camiinthisthangGood OPSEC at conferences in generalWhile those are important and contain good information relevant to staying safe in Bogota, I thought it might be helpful to dig deeper and tap into the wealth of existing information on conference OPSEC.OPSEC for Defcon #1 from Darkangle.netBefore we continue, you should understand that everyone’s security needs are not the same.ZW: What is the personal threat model? Most crypto people don’t need to defend against nation states.Maintaining custody of your devices is a sound defense from parties that would seek to make modifications to your equipment or outright steal your hardware. This means of security only requires you to make sure you know where your stuff is, and whose handl...

With a healthy balance of enthusiasm and skepticism, we dig into a weekly look at crypto, cutting through the misinformation and hype in search of signal in the noise.Episode SummaryThis week we discuss the draft of the US House’s Stablecoin bill. CFTC’s 250k fine for BzX & the Ooki DAO. We talk about the 0xBAD MEV bot getting owned, and we dig into the recent paper on reversible ERC20 and ERC721 transactions.I, Degen - Weekly9/20/2022 - From CryptoBreifing - US House proposes stablecoin bill that would put a two-year ban on algorithmic stable coinsU.S. lawmakers are reportedly drafting a bill to place a two-year ban on certain stablecoins.The House Stablecoin Bill would target “endogenously collateralized stablecoins.”The bill would allow both banks and non-banks to issue stablecoins. However, bank issuers would need approval from federal regulators such as the OCC. As for non-bank issuers, the legislation directs the Federal Reserve to establish a process for making application decisions.The House Stablecoin Bill would make it illegal to issue or create new stablecoins that mimic the functionality and features of TerraUSDNOTE: This is an early draft, not final so take it for what it is.2M in assets seized from Whitby, Ont Man Aiden Pleterski, who calls himself “Crypto King,” had $2 million of assets seized, Lamborghini, two McLarens, and two BMWsPleterski was reportedly given $35 million by 140 investors.Now, he’s being sued by former investors in a bankruptcy proceeding and two civil lawsuits.Investors told the publication that at least $35 million given to Pleterski’s company, AP Private Equity Limited, went missing.No criminal charges yet9/22/2022 - CFTC Press ReleaseBy transferring control to a DAO, bZeroX’s founders touted to bZeroX community members the operations would be enforcement-proof—allowing the Ooki DAO to violate the CEA and CFTC regulations with impunity, as alleged in the federal court action. –> CFTC Penalizes Blockchain Protocol $250K, Files Action Against Successor DAO 9/27/2022 - Coindesk The CFTC Served Ooki DAO Papers by Posting Them in an Online Discussion Forum Members of Ooki DAO – which operates a protocol that offers illegal, off-exchange tokenized margin trading and lending services – were notified of the lawsuit when a CFTC paralegal posted the complaint and other documents to an online discussion forum meant for DAO members to discuss governance issues, a CFTC attorney claimed in a court filing.

Listen at: idegen.fmContact us: @idegenfmIntroWelcome to I, Degen - A podcast about crypto technology, security, and culture. With a healthy balance of enthusiasm and skepticism, we dig into a weekly look at crypto, cutting through the misinformation and hype in search of signal in the noise.Episode SummaryIn this episode, we hunt for Do Kwon and look at the White House’s comprehensive framework for the responsible development of digital assets. Then we look into Wintermute’s 160M key generation issue. We discuss emerging post-merge Ethereum narratives and the Omni bridge replay attack. We also get into an IRL customs scam for our hack attempt of the week.I,Degen - Weekly9/14/22 - South Korean Court Issues Arrest Warrant for Terra Luna founder Do Kwon [2]The wanted crypto developer Do Kwon, who is accused of fraud by investors following the $45 billion (€45 billion) collapse of his cryptocurrencies Luna and TerraUSD, is reportedly trying to evade South Korean authorities.Prosecutors have accused Kwon of financial fraud, arguing that his terraUSD stablecoin was a kind of investment security under South Korea’s capital markets act [2]Kwon moved from South Korea to Singapore, where the now defunct stablecoin issuer Terraform Labs, which he co-founded, has a base. However, Singapore Police Force said on Saturday he is currently not in the city-state.South Korean prosecutors told Bloomberg in a text message on Monday that there has been “circumstantial evidence of escape” since he left Singapore. The media outlet said prosecutors declined to comment on whether the office knows of Kwon’s whereabouts or if it will contact the international police agency Interpol.Last week, Kwon was charged with violating the Capital Markets Act, and an arrest warrant was issued for him and five allegedly connected to the case who were believed to be in Singapore. –EuroNewsWhite House Releases Comprehensive Framework for Responsible Development of Digital AssetsOver the past six months, agencies across the government have worked together to develop frameworks and policy recommendations that advance the six key priorities identified in the EO: consumer and investor protection; promoting financial stability; countering illicit finance; U.S. leadership in the global financial system and economic competitiveness; financial inclusion; and responsible innovation.The nine reports submitted to the President to date, consistent with the EO’s deadlines, reflect the input and expertise of diverse stakeholders across government, industry, academia, and civil society. Together, they articulate a clear framework for responsible digital asset development and pave the way for further action at home and abroad.Protecting ConsumersStill sellers commonly mislead consumers about digital assets’ features and expected returns, and non-compliance with applicable laws and regulations remains widespread. One study found that almost a quarter of digital coin offerings had disclosure or transparency problems—like plagiarized documents or false promises of guaranteed returns.The reports encourage regulators like the Securities and Exchange Commission (SEC) and Commodity Futures Trading Commission (CFTC), consistent with their mandates, to aggressively pursue investigations and enforcement actions against unlawful practices in the digital assets space.The reports encourage Consumer Financial Protection Bureau (CFPB) and Federal Trade Commission (FTC), as appropriate, to redouble their efforts to monitor consumer complaints and to enforce against unfair, deceptive, or abusive practices.The reports encourage agencies to issue guidance and rules to address current and emergent risks in the digital asset ecosystem. Regulatory and law enforcement agencies are also urged to collaborate to address acute digital assets risks facing consumers, investors, and businesses. In addition, agencies are encouraged to share data on consumer complaints regarding digital assets—ensuring each agency’s activities are maximally effective.The Financial Literacy Education Commission (FLEC) will lead public-awareness efforts to help consumers understand the risks involved with digital assets, identify common fraudulent practices, and learn how to report misconduct.Advancing Responsible InnovationThe Office of Science and Technology Policy (OSTP) and NSF will develop a Digital Assets Research and Development Agenda to kickstart fundamental research on topics such as next-generation cryptography, transaction programmability, cybersecurity and privacy protections, and ways to mitigate the environmental impacts of digital assets.Quite a bit more to the report.And the Forbes Headline reads… Joe Biden Just Sent A Stark Warning To Bitcoin And Crypto After $2 Trillion Price CrashWhat is your narrative?What do the machines think?(June 9th, Wintermute OP issue)[https://rekt.news/wintermute-rekt/] and now this… ()[https://rekt.news/wintermute-rekt-2/]Let’s start with a story that broken on September 14th. 1Inch, a dex aggrator protocol’s community discovered an issue with Profanity, a Ethereum address generator toolEven worse, the possibility of this issue was raised on the Profanity Github on January 17th, 2022.Why didn’t Wintermute act when the Profanity issue was raised with proof six days ago? Well, the did:Around the time that the disclosure happened, Wintermute removed all ether from an admin address which suggests that they realized it might have been vulnerable. However, they forgot to remove this address as an admin from their vault.The attacker is likely a seasoned hacker/solidity developer. They created a helper contract, deposited stables into curve to avoid blacklisting, and figured out this vulnerability in a closed sourced vault contract in the first place. –Mudit’s BlogThe stolen funds were mostly various stablecoins, totalling $118.4M. The majority of these were deposited into Curve’s 3pool, presumably in an attempt to avoid any blacklisting.The exploiter is now the 3rd largest holder of 3CRV with over 13% of the supply.I, Degen - Deep DiveReflecting on the merge ETH?Ethereum itselfSocial Attacks - Narrative-based attacks in crypto.

With a healthy balance of enthusiasm and skepticism, we dig into a weekly look at crypto, cutting through the misinformation and hype in search of signal in the noise.Episode SummaryAll eyes are on Ethereum - we are now less than four days out from the merge. We’ll talk about some possible scenarios the merge might bring and what you can do to stay safe during the merge. We’ll also look into recent updates on the Tornado Cash sanctions, a new report on fraudulent crypto trading volume, and other crypto security-related news.I,Degen - WeeklyCryptosphereFrom August 23rd, SudoRare, a LooksRare clone rugs 820K after just 6 hours of operation Rugged funds likely moved to a KYC’d address on Kraken.SudoRare, an NFTplatform that forked from SudoSwap and LooksRare, is just the latest crypto project to run off with users’ funds.

In some cases trading bots execute these wash trades in tokens, increasing volume, while at the same time insiders reinforce the activity with bullish remarks, driving up the price in what is effectively a pump and dump scheme. Wash trading also benefits exchanges because it allows them to appear to have more volume than they actually do, potentially encouraging more legitimate trading.“Fraudulent or non-economic”The biggest problem areas regarding fake volume are firms that tout big volume but operate with little or no regulatory oversight that would make their figures more credible, notably Binance, MEXC Global and Bybit. Altogether, the lesser regulated exchanges in our study account for approximately $89 billion of the true volume (they claim $217 billion).On Forbes method:We apply volume discounts based on a proprietary methodology that relies on 10 factors such as an exchange’s home regulator if any and volume metrics based on an exchange’s web traffic and estimated workforce size.So, private trading firms numbers are being grok’d by proprietary methodology.Worth note, the Bitwise Study from early 2019 said 95% of BTC trading was fake… so it’s getting better.In case you’re interested in this topic, here is another nice paper from 2019 that talks about fake BTC tradingspoiler! -New Netflix show on John Mcafee rasies questions about his death - supposedly he called his ex-gf after his ‘death’ to say he faked it.Australia Establishes Federal Crypto Police Launched in August, the unit will help combat crypto criminals by targeting their assets and providing investigative tracing capability and insight to other AFP authoritiesThe new crypto unit will operate as part of its Criminal Assets Confiscation Taskforce (CACT), which has been seizing illicit crypto funds since 2018, but without a dedicated standalone teamThe Australian Federal Police have confiscated over AU$600 million (US$408 million) in illicit funds and property since 2020, and though the amount of crypto funds seized were small compared to “traditional” criminal assets, the additional focus helps provide intelligence insightsSolana didn’t go down this week - high TPS spike that might have caused a network outage before, didn’t cause one this time.September 5th withdrawals frozen at crypto mining firm Poolin because of a lack of liquidity - From theBlock.Poolin, one of the world’s biggest crypto mining pools, is suspending bitcoin and ether withdrawals from its wallet service due to “liquidity problems.”And now, from September 9th Bitcoin hash rate cut in half as miners leaveThis is significant because 1) Poolin is a China-based mining pool service, operating in China after the mining ban, and 2) the pool was estimated to have roughly 10% of the hash rate before withdrawals were suspended.Flash Loan used against single NXUSD market on NerusAt approximately 10:30PM UTC on September 6th, the Nereus team notified the community of an incident through the community discord; this was later picked up by CertiK and other on-chain analysis groups and reported broadly as a flash-loan exploit resulting in a $371k gain.An exploiter was able to deploy a custom smart contract and that leveraged a $51M flash loan to manipulate the AVAX/USDC Trader Joe LP pool price for a single block resulting in the ability for the exploiter to mint 998,000NXUSD against ~$508k worth of collateral.In the hours that followed, Nereus quickly consulted s...

They recently came out of stealth mode to launch their NFT lending platform and bravely agreed to an open-source audio audit with us.Welcome to I, Degen gentleman, and thanks for taking the time to chat with us. Before we jump into the audit, can you tell us a bit about yourselves and what NiftyApes is?Intros Kevin Seagraves & Zach Herring:Who are we talking to?Tell us about your background and how you built an NFT lending platform.For KS: Can you tell us more about your work with ETHSecurity?Hunt questions:Intro NiftyApes:What is NiftyApes?How does it work?Why did you build it?Who’s gonna use it?What is HARBERGER AUCTION?When release?Let's talk about the “regen” side of Nifty Apes and the 1%? that goes to public goods. Why was it essential for you to do this?Open Source Audit:Security audits are expensive and rarely a priority for founders. This is especially dangerous when it comes to Defi apps and protocols, given the natural ability of an attacker to take something of value.The idea for our Open Source Audit is to help others learn about securing a crypto project by asking some questions about how you’ve approached the security of the Niftyapes.Can you give us a high overview of the tech stack? How does NiftyApes look from a zoomed-out view? What web2 components are at play, and what web3?Can you talk a little bit about your overall approach to securing niftyapes?How have you approached the security in your web2 interface?KS: we only store tx receipts in DB after a tx has taken place and been confirmed, so the attack surface for us on Web2 is low.3(b). Have you taken steps to ensure your DNS records are secure?Contract audits - Can you give us an overview of your process with the contract audits?How did you find your auditors?What was the process like?What did they find?You guys have gone out of your way to make security a priority for NiftyApes (from the front page):Does NiftyApes have a bug bounty program? If so, how does it work?Nocoiners and others have been all over a brewing problem at NFT lending platform, BendDAO. Specifically,“The NFT lending platform BendDAO has collateralized almost 3% of the entire Bored Ape collection, and many NFTs have recently entered the “danger zone” of liquidation.”ZW: Would this kind of thing be a potential problem on Niftyapes too?Game theoretical bugs are new and emerging class of attacks in DeFi that don’t necessarily exploit bugs in code but instead bugs in the relationship between values of pools, balances, and the connected systems.In the coming years, we will likely look back at this as the golden age of on-chain hacks, where trivial bugs lead to massive payouts for blackhats. ZW: Are you tracking any risks related to game theoretic bugs? For example like, Flash Loan attacks?The unprecedented sanctioning of the Tornado Cash contract addresses by US Treasury in early August has added a new complexity for DeFi developers. What is your take on the sanctions at NiftyApes?Any advice for crypto founders on developing and deploying more secure projects?Outro Questions:Top musical artist you’re listening to right now?Tech gadget you can’t live without?Best book you’ve read recently?

I, Degen - E12: Ethereum Fights to Remain Censorship Resistant - 8/24/2022Listen at: idegen.fmContact us: @idegenfmIntroWelcome to I, Degen - Each week, we track down and explore the most exciting crypto stories. Hacks, mysteries, exploits, and anything that feeds our crypto curiosity. We dig in, cutting through the misinformation and hype in search of a signal in the noise.Episode SummaryThis week we have a bunch of weekly news updates. Then we take a deep dive into the upcoming Ethereum merge and rippling effects on Ethereum protocol level censorship from the OFAC Tornado Cash sanctions.I,Degen - Weekly Stories1.The Chicago Mercantile Exchange (CME) Group will launch Ethereum option contracts on its platform on September 12. The company announced that it’s waiting for regulatory review, and if approved, these new investment products will join its ETH futures and mini futures contracts.2.Alleged Russian Money Launderer Extradited from the Netherlands to U.S.According to court documents, Dubnikov and his co-conspirators laundered the proceeds of ransomware attacks on individuals and organizations throughout the United States and abroad. Specifically, Dubnikov and his accomplices laundered ransom payments extracted from victims of Ryuk ransomware attacks.3.Reaper Farm Yield Aggregator Owned4.TikTok monitoring all keyboard inputs and tapsWhen you open any link on the TikTok iOS app, it’s opened inside their in-app browser. While interacting with the website, TikTok subscribes to all keyboard inputs (including passwords, credit card information, etc.) and every tap on the screen, like which buttons and links you click.5.Wrench Attack - 3 men targeted an Indian realtor they knew held bitcoin and abducted him while posing as sellers of a plot of land. They tortured him for 3 hours until he gave them 8 BTC. - [r/CryptoCurrency post]Victim was not hurt, according to his wifeThe suspect was caught using a trap to lure them back to the kidnapping spot Note: These attacks are rare but often receive much media attention. Nonetheless, it’s essential to be aware. Often, you see comments like, “yeah, this is why you keep your crypto a secret!”, which happened on the Reddit post. However, is that advice practical for 'mainstream adoption?6.Hackers steal crypto from Bitcoin ATMs by exploiting zero-day bug - via Bleepingcomputer, August 20, 2022Hackers have exploited a zero-day vulnerability in General Bytes Bitcoin ATM servers to steal cryptocurrency from customers.When customers would deposit or purchase cryptocurrency via the ATM, the funds would instead be siphoned off by the hackers.The attacker was able to create an admin user remotely via CAS administrative interface via a URL call on the page that is used for the default installation on the server and creating the first administration user. This vulnerability has been present in CAS software since version December 2020. General Bytes Official Advisory7.iOS VPNS have leaked traffic for years, Proton CEO says.Apple notified more than two years agoclaim/issue: any connections established BEFORE activating the VPN are not tunneledjanky trick that may or may not fully work: Turn on your VPN, then turn on airplane mode off and on.8.U.S. Lawmaker Questions Treasury Over Tornado Cash Sanctions August 23, 2022 via CryptoBriefing.comRep. Tom Emmer (R-MN) raised questions over the decision to sanction Tornado Cash in a letter sent to the Treasury Department today.Emmer called the ban of a “neutral, open-source, decentralized technology” a “divergence” from historical precedent.Among other things, Emmer asked what recourse law-abiding users of Tornado Cash may have to claim funds trapped in the protocol.I, Degen - Deep Dive - The Merge & Ethereum censorship in a post-sanctioned TC world.What is the merge TLDR?The Merge represents the joining of the existing execution layer of Ethereum (the Mainnet we use today) with its new proof-of-stake consensus layer, the Beacon Chain. It eliminates the need for energy-intensive mining and instead secures the network using staked ETH. A truly exciting step in realizing the Ethereum vision – more scalability, security, and sustainability.- https://ethereum.org/en/upgrades/merge/What's the problem? OFAC Tornado Cash sanctions fallout continues.Ethermine, the largest Ethereum pool, has refused to pack Tornado Cash-related transactions into blocks in the past week. Several pool technicians also confirmed the news and said it was the first time in history.— @WUBLOCKCHAIN AUGUST 20, 2022 - https://t.co/XLC3ZjddLRIndividual miners can refuse to include whatever they want, but it has little effect; the transaction just gets into the next block. Need a 51% attack (so, reverting blocks and not just excluding txs) to fully prevent txs from being included.— @VitalikButerin August 19, 2022 The Case for Social Slashing So, what’s the issue here?Well, one of the absolute core purposes for blockchains such as Ethereum is to provide neutrality and censorship resistance. That’s why we tolerate that the system is slow and expensive to use at times—because of these unique qualities. A threat to censorship resistance is a threat to the system’s raison d’être.Other censorship & merge-related stuff Centralized censorship of privacy protocols outside of Tornado CashRecently, FTX froze a user account who sent coins to @aztecnetwork’s zkmoney. According to FTX, Aztec Connect - Aztec network / zk money has been identified as a mixing service, which is a high-risk activity prohibited by FTX.

That is to say, provide privacy or ‘mix’ coins.When you deposit your 1 ETH on the contract, you have to provide a “commitment”. This commitment is stored by the smart contract. When you withdraw 1 ETH on the other side, you have to provide a “nullifier” and a zero-knowledge proof.

We dig in, cutting through the misinformation and hype in search of signal from the noise.Episode SummaryThe word of the week is chaos. From the first-of-its-kind decentralized looting mob destroying Nomad to the mysterious draining of more than 8K Solana wallets, it’s been a crazy week. Sadly, there is more.**Quick word on signal **I,Degen - WeeklyReaper Finance - FTM based hacked for 1.7MM Audit, Significant code update, no audit, owned.The SEC is accusing 11 individuals of running the Forsage Ponzi that generated more than 300 million from users on several blockchains (ETH, BNB,Tron) https://defi-planet.com/2022/08/officials-of-forsage-crypto-accused-of-running-a-300-million-ponzi-scheme/Two founders pled guilty to securites fraud from a 2017 ICO called “Dropl” for scamming users out of 1.9 million. The founders were sentenced to 2.5 and 3 years for their crimes (https://coinfomania.com/two-men-bag-three-years-in-prison-ico-fraud/)A bill reaches the Senate that would classify Bitcoin and Ethereum as commodities and put their regulation under the CFTC.

Iconic 90’s band? Nope in this context, Solana Based Yield Protocol (what even is a ‘yield protocol’?). Also, a stablecoin.@Huntfrye Nirvana Finance, a Solana-based yield protocol. Nirvana allowed users to earn annual yields on their locked assets by creating and destroying tokens based on user demand as the ANA tokens were bought from and sold to the protocol.Looks pretty similar to some other algorithmic coins that rebase or change supply daily due to demandIs this Similar to the Beanstock flash loan attack we talked about on I Degen a few episodes back?Hacked for 3.5 MM using FlashLoansWhat’s a Flash Loan?The loans enable merchants to obtain unsecured loans from lenders using smart contracts in place of intermediaries. No collateral is required because the contract only considers the transaction complete when the borrower pays the lender.If a borrower fails to repay a flash loan, the smart contract will halt the transaction and repay the lender’s money. – DeFi PlanetI, Degen - Deep Dives1) Nomad looted for 190MM by a decentralized mobWhat is Nomad?Nomad is a bridge that allows you to move assets from chain to chain, such as avalanche, Ethereum, Moonbeam, EVMOS, and Milkomeda. “Wow I haven’t even heard of a couple of those”What happened?TLDR; ~190 MM, ~2.5 Hours, Initial TX exploiting the bridge, then a swarm of copycats loot the protocol.Hunt: why not take it all at once? Good question.Zak: let’s talk about how the hack worked.How did it happen?Bridge stores funds - deposit ETH, receive XYZ on MoonbeamMerkel Tree used to validate cross-chain transactionsAfter a failed first attempt (costing $350k in gas), the original attacker’s exploit tx, which was copied by those that followed, was able to call the process() function directly, without having first ‘proved’ its validity. rekt.newsThis meant any process() calls could be executed as valid. In fact, a more sophisticated exploiter could have written a contract to drain the whole bridge for themselves.Initial reports claim the root of the issue was called out in the audit; however, that seems incorrect. Perhaps it was the audit the led the attacker to look at this section of the code. Still, the vulnerability that was exploited appears to have been introduced to the repository on May 23rd and then pushed to the blockchain with an update in June.DeFi DominosThe collateral damage from the unbacked assets is also severely affecting the chains that depended on Nomad. Moonbeam, EVMOS and Milkomeda have all taken a significant hit to their TVLs. rekt.newsHunt: The most interesting and crazy part about this hack to me was that other people noticed the hack going on in real-time, joined in the fun, and were able to withdraw funds. Whether these other users who were getting in on this honey pots were White Hats and trying to take some of the funds before the attacker could, or were they maliciously trying to steal for themselves? Nomad has placed an address on their home page asking for any white hats to return funds to a specific address.Did you see that meme floating around Twitter? It was a bunch of people looting a stoor who were the copycat hackers after the main attacker busted into the store initially.2) Solana Wallet HackWhat is Solana?@Huntfrye Solana is an extremely well-funded alternate layer 1 that boasts as one of the main competitors to Ethereum. Most people agree that Solona has sacrificed some of the decentralization and security to provide extremely high throughput.What happened?Roughly 9K addresses on the Solana network were compromised, draining more than 6MM worth of various tokens. For perspective, there are more than 25MM addresses on Solana as of this writing.11PM UTC on August 2nd, 2022, SOL and USDC started mysteriously being transferred from wallets.A host of wild theories spread across crypto twitter including fro...

Thus, the proxy doesn’t only forward transactions to and from the logic contract, but also represents the pair’s state. The state is in the proxy and the logic is in the particular implementation that the proxy points to.Solidity uses slots to store data. [Storage Collision]( https://docs.openzeppelin.com/upgrades-plugins/1.x/proxies#unstructured-storage-proxies)> Using this bug, the attacker was able to call the initializer method of deployed Audius contracts that implement Initializable and change storage state that is intended to be set only once in initialization. In other words:>the attacker was able to reinitialise governance contracts, delegating a large number of governance tokens to themself and bypassing safeguards meant to limit malicious proposals.So, storage collision leads to deployment of malicious governance contract, and massive fraudulent token delegation which was used to pass a malcious governance proposal to send AUDIO tokens from the Audius community pool to the attacker. Quick massive slippage sale of 6.1MM worth of AUDIO on Uniswap for ~1MM USD/704 ETH, ETH into TornadoCash. Take aways:- super fast response, vuln mitigated within a few hours of discovery.  - > These contracts were deployed in October 2020 and this vulnerability has been live in the wild since that time. - [audius-governance-takeover-post-mortem](https://blog.audius.co/article/audius-governance-takeover-post-mortem-7-23-22)- Human angle - why swap 6MM for 1MM?

Each Akutar grants you entry into the ever-expanding Akuverse, where lines are blurred between the digital and physical worlds and owners gain exclusive access to culture-defining experiences, products, and collaborations.– Akutars on OpenSeaSo this drop was dutch auction with a unique feature that allowed the lowest bid to set the price for all minters. – TweetThen, when the auction ends, any bid higher than the lowest bid will receive a refund of the lowest bid, minus gas fees.This is an interesting and cool mechanism. However, there was some faulty logic in the contract.First issue: If you bid on the auction from a contract, and that contract didn’t have a fallback function to handle incoming ETH, then the refund loop would fail. This was exploited, however, the attacker was kind enough to build a switch into their contract that would bypass the failure and allow the refund loop to continue.malicious bidder contract's messageThere is some mention that this bug was pointed out to the AkuDreams team ahead of time and they ignored it. I wasn’t able to verify that.Next Issue: Bigger issue. The contract was designed to keep track of the bids, and addresses that made those bids. A simple ++ was used to increment the counter. However, this counter didn’t account for cases where a single address bid on more than one Akutar. AKA, multi-mint in a single transaction. This left the total bid count short. There were 5495 total Auktars to be auctioned, but bid counter only made it to 3669.During the refund loop, there is a check to confirm:# this will fail because of the bid counter issuerequire(_refundProgress and then, in the claimProjectFunds function:# This too will failrequire(refundProgress >= totalBids)Sooo… 11k ETH is permanently stuck.What’s strange:AkuDreams Twitter appears unfazed.not audited?not tested?lots of questionable info floating around on twitter (not strange I guess)links:Aku, The Moon God, and the new age of Web3 Mediahttps://www.instagram.com/aku.dreamsNice twitter write up from 0xInuarashiAkutars Auction ContractI, Degen - Freestyle ConvoMusk buys Twitter [[[Outro]]]We do our best to report accurately on the topics we discuss but we’re not always going to get everything right.

Jared Huffman (D-Calif.), who leads a subcommittee within the House of Representatives’ Natural Resources Committee, has recruited almost two dozen Democratic colleagues to urge federal environmental officials to devote further scrutiny to the consequences of cryptocurrency mining. - CoindeskDegen Deep DiveBeanstalk Farms Flash Loan Governance AttackTLDR: On April 17th, 2022 an attacker used a barrage of flash loans to purchase a majority of BEAN tokens, the native governance token for Beanstalk Farms. Using this temporarily loaned voting power allowed them successfully pass an emergency governance proposal that drained the protocol of 76M in assets, sent 250K of the stolen money to the Ukraine War Fund, and sent the price of the stable BEAN tumbling.Who:victim: bean.money aka BeanstalkBeanstalk is a decentralized and transparent solution to DeFi’s endemic stablecoin supply shortage. It was designed from first principles to be a paradigm-shifting DeFi primitive that makes decentralized, cost-efficient stablecoins available to anyone with an internet connection.Beanstalk was initially launched in August 2021 with just 100 Beans and has never taken traditional funding. Over the last eight months, Beanstalk organically grew to $100M in market cap, attracting $144M in long term-incentivized liquidity.Beanstalk: The Path ForwardFrom the whitepaper:To date, flawed stablecoin implementations sacrifice the main benefits of decentralized computing by requiring trust in a centralized party and limit their potential market capitalization by imposing collateral requirements.A stablecoin that (1) does not compromise on decentralization, (2) does not require collateral, and (3) trends toward more liquidity and stability, will unlock the potential ofDeFi.We propose an Ethereum-native, credit based stablecoin protocol that issues anERC-20 Standard token that fulfills these requirements.An on-chain price oracle leverages an existing centralized bridge between the Ethereum blockchain and the rest of the world to create a decentralized, reliable and inexpensive source for the price of a nonEthereum-native value peg.A Decentralized Autonomous Organization (DAO) governedby a yield generating, inflationary, ERC-20 Standard token simultaneously provides security, encourages consistent liquidity growth, and dampens price volatility.Attacker:Anon/unknownWhat:attack details:Created two malicious governance proposals and submitted them to the governance contract and wait for 24hrsAAVE FlashLoans sourced from Tornado Cash --> Synapse Protocol Bridge:350M DAI500M USDC150M USDTBought 32M BEAN on Uniswap V2bought 11.6M LUSD?These tokens were used to add liquidity to Curve pools with BEAN for the governance votingVoted for and passed, BIP-18 & 19 (malicious proposals)Pull back liquidityRepay flash loansConverted all received funds into 24,800 ETH ($76M)ETH moved to TornadoCash– from BEANSTALK - REKT & PeckShield’s step by stepPresumably, to avoid suspicion of an inside job, Publius, the anon behind the protocol, took the decision to reveal their identity as a group of three in a statement published to Discord.From ^^ rektHow:From Beanstalk whitepaper:6.5 GovernanceA robust decentralized governance mechanism must balance the principles of decentralization with resistance to attempted protocol changes, both malicious and ignorant, and the ability to quickly adapt to changing information.In practice, Beanstalk must balance ensuring sufficient time for allecosystem participants to consider a Beanstalk Improvement Proposal (BIP), join the Silo and cast their votes, with the ability to be quickly upgraded in cases of emergency.6.5.2 Voting PeriodA Voting Period opens when a BIP is submitted to the Ethereum blockchain and ends at the beginning of the 169th Season after it is submitted, or when it is committed with a supermajorityDoesn’t matter though, as it looks like a super majority of tokens was used to override the 169th season (~7 days).5 SeasonsThus, Beanstalk creates a cost-efficient protocol-native timekeeping mechanismand ensures cost-efficient code execution on the Ethereum blockchain at regular intervals.Confusing… How about this:Seasons are the Beanstalk-native timekeeping mechanism.

Before we dig in, it’s worth noting that this is not a new issue for Coinbase. The BCH Coinbase insider trading issue was a thing in 2019Post from Reddit user dragondude4 on r/cryptocurrencyEarlier today Coinbase made a “transparency post” naming about 50 assets that they are planning to list on their exchange.
