This 51% threshold doesn't pose an immediate threat to Tornado Cash users, because even validators that censor transactions will still attest to the validity of blocks created by non-censoring validators. However, if 51% or more of validators were to also stop attesting to non-censored blocks, they would no longer be able to be added to the chain.
Amusingly, one of the transactions by the hacker was frontrun by a MEV bot known as 0xa57, which made a tidy 480 ETH (~$623,000) from the attack. The second transaction succeeded, landing the attacker 268 ETH (~$348,000). According to a MEV researcher, 0xa57 has been known to return funds that were obtained as a result of a hack.
Now that year mark is approaching, and a report from Rekt alleges that DAO Maker is trying to wiggle out of their promises through a governance vote, which they've framed as trying to "prevent major $DAO DUMP from USDR distributions". Meanwhile, they've deleted the post that explained the original distribution plan.
Most members of the DAO today were not affected by the attack, and so stand to benefit from not honoring the payout. One voting option suggests that these users "had their chance" to cash out their USDR, apparently ignoring that people were holding out for the promised 110% redemption.
Some whistleblowers have also claimed that team members have recently moved large quantities of DAO tokens to various wallets to vote. Some have also claimed that those team members recommended buying USDR tokens several months ago for below $1.10, as a safe arbitrage opportunity when they became redeemable for that amount.
On October 11, a crypto developer advocate wrote a thread about the group, starting by saying "Most of the members of Blu3DAO are great people working towards a good cause. Despite this, there have been things around their finances that I personally have found questionable. I've refrained from calling them out & it's something that has bothered me for a long time". She went on to allege that the group had solicited over $1 million in grant money from the Harmony community, misusing a personal relationship with a member of Harmony to continue to obtain grant funding while the group had paused grant allocations, and using funds to personally benefit the founders.
"I run an organization dedicated to advancing womens & nb ppls careers. And this type of grifting only hurts everyone," wrote the developer advocate in her Twitter thread. She also wrote, "In the coming days they'll post some fraudulent report clearing them from wrongdoing. They're running an elaborate scam with many wallets. One of them is literally married to a decision maker at harmony. Lmaooo. Fuck the[m] scammers"
Blu3DAO's founders responded to the allegations by claiming that they had only ever received $75,000 of the $1 million they were committed by Harmony, and that the funds were still in the DAO treasury. They also claimed that the Blu3 DAO members were never paid for their work, and that the money from Harmony was "flow-through reimbursements for scholars/hackers' travel expenses".
The man in the photo subsequently tweeted his version of events, in which he described encouraging the woman and her friends to jump up while taking a 3D photograph, and then gave them a thumbs-down gesture when they reacted in annoyance to him. He then claimed that they harassed him throughout the conference, by stalking him throughout the conference and posting his photo online with vague allegations of harassment.
The woman later elaborated on the event that had precipitated her report to Devcon staff, saying the man had been "verbally boo'ing and taunting us" at the photo booth.
It's a little unclear what actually happened at the event and who is at fault, something I don't intend to speculate on as a complete outsider. However, what's not unclear is the reaction from some people in the crypto community, who have used the incident (and their belief that the woman fabricated the harassment story) as evidence that all women, people of color, and "wokeness" are a blight on the crypto space. Various crypto enthusiasts have used the opportunity to denigrate what they view as a general issue of "feminazis", "purple hairs", or "SJWs" in crypto, and DAOs that aim to encourage gender minorities to engage with crypto. "Letting SJWs infiltrate into crypto was a huge mistake", wrote one person. "This is the woke crowd we didn't have to deal with last cycle. They came into crypto with their distorted vision of everything. [Crypto Twitter] got your back, mate."
The OFAC sanction was imposed due to 116,421 reported sanctions violations in which Bittrex failed to prevent people in Crimea, Cuba, Iran, Sudan, and Syria from using their service. In total, these prohibited individuals performed more than $263 million in transactions on the platform.
The FinCEN fine was imposed due to "willful violations" of the Bank Secrecy Act's requirements pertaining to anti-money laundering (AML) and suspicious activity reports.
Mango Markets posted on Twitter to urge users not to deposit into the project, and asked the hacker to contact them "to discuss a bug bounty". The hacker had their own plans, instead submitting a governance proposal in which they would return $46 million of the stolen funds (keeping $70 million) in exchange for a promise that the protocol would not try to freeze the assets or pursue criminal charges. The hacker then used their 32 million governance tokens to vote in support, but ultimately were not able to get the proposal to pass. A different proposal with largely the same terms, but which left the attacker with only $47 million of the stolen funds, passed shortly after.
On October 11, the QANX Bridge's deployer wallet was compromised thanks to the vanity address generator bug. Although QAN had not directly used the Profanity project to generate the address, they used a project called vanity-eth-gpu, which had derived its code from Profanity and so inherited the bug. QAN is a layer 1 blockchain that claims to be quantum-resistant.
The thief stole 1.44 billion QANX from QANX's BNB Chain bridge, which they traded for 3,090 BNB (~$837,000) and tumbled through Tornado Cash. One minute later, they drained 1.43 billion QANX from QANX's Ethereum bridge, traded it for 255.4 ETH (~$327,000), and tumbled it as well. In total, $1.16 million was cashed out via Tornado. News of the attack, and the attacker's sell-off, caused the QANX price to plummet by 94%.
The attacker still holds more than 1 million QANX, nominally worth $608,000. However, QAN withdrew liquidity for the project on Uniswap and Pancakeswap, which will make it more difficult for the attacker to sell off their remaining tokens.
This was the second theft affecting the QAN platform this year. In May, an attacker stole 4.4 million QANX, which they traded for 370 ETH (valued at ~$707,000 at the time).
The attack impacted assets on multiple chains. The attacker tumbled 114 ETH (~$146,000) through Tornado Cash shortly after the hack, along with 179 BNB (~$48,500). The full extent of the attack is still being measured. The buggy contract that enabled the attack had been audited by blockchain security firm PeckShield, but the vulnerability had apparently gone undetected.
Although CNN claimed in their shutdown announcement that "Vault was originally launched as a 6-week experiment", CNN had not mentioned that the project was an experiment that was expected to possibly end. As recently as last month, Vault had been teasing upcoming events scheduled around election day in November, and encouraging users to buy more Vault NFTs to access the upcoming drops.
As an apparent attempt to placate angry users worried that the value of their NFTs might drop, CNN promised to return "either FLOW tokens or stablecoins" for "roughly 20% of the original mint price". However, the project is built on the Flow blockchain, where users can only withdraw stablecoins $10 at a time — and with a $4 fee on each withdrawal. Some angry users in the project's Discord channel threatened legal action, claiming that CNN had rug pulled.
