BitStable decides to burn most tokens after public sale goes wrong

BitStable launched their BSSB token in a public sale only to watch as all tokens sold out in one block. Four entities acquired the majority of the BSSB tokens, an outcome that the team had been hoping to avoid in the interest of "fairness and integrity". As a result, the team announced that they would burn 75% of the tokens.

Some applauded the decision, seeing the token hoarding as an unfair tactic that deprived others who wanted the tokens of their opportunity to buy any. However, some — particularly those who succeeded in buying tokens in the initial sale — worried that they were being "rugged" as the team threatened to destroy their tokens. Others objected based on the "code is law" ethos: "Basically we used ur platform and ur rules - u said ur selling at 500k mcap valuation and now changed it to 3m mcap valuation after it sold out - straight rug material u can't do that lmao", wrote one person on Twitter.

SoFi neobank ditches crypto

After entering the crypto sector in 2019, the neobank SoFi is jettisoning the blockchain portion of its business by mid-December. Customers are being given the option to move their accounts to Blockchain.com; otherwise their assets will be liquidated.

The move is likely tied to its bank charter, which was conditionally approved with a two-year period in which it was required to receive approval for its crypto business. SoFi had previously described discussions with the Federal Reserve "to determine whether there is a path to conform our crypto-related activities to the requirements of the Bank Holding Company Act" — this move suggests they decided there was not.

Hounax crypto scam steals $19 million

A scam Hong Kong cryptocurrency platform called Hounax swindled its customers out of HK$148 million (US$19 million). The group drew in customers by offering financial expertise on social media and awarding prize money to those who signed up to the platform. While some customers successfully tested whether they could withdraw their funds earlier on, the platform later stopped allowing customers to withdraw, or told them they would need to pay additional fees to do so.

The Hong Kong Securities and Futures Commission added Hounax to its warning list on November 1, a move that victims have criticized as much too late to stop the damage.

Bitcoiner spends $3 million on transaction fee

A Bitcoiner making a large transaction ended up spending 83.64 BTC (~$3 million) of the 139.42 BTC (~$5.1 million) transaction on transaction fees, effectively spending $3 million to send what ended up being a $2 million transfer. This likely error on the sender's part has become the largest transaction fee in Bitcoin history.

A similar incident occurred in September, when the Paxos crypto firm erroneously paid a $500,000 fee to send $1,865. They attributed the huge fee to a bug in their software, and the F2Pool mining pool (who had mined the block and received the fee) opted to return the overpayment.

KyberSwap hacked for $48 million

The KyberSwap decentralized exchange was hacked by an attacker who stole large sums of ETH, wETH, and the USDC stablecoin. Altogether, the assets are valued at around $48 million. The attacker was able to exploit a complex bug in a feature for liquidity pool providers. Prior to the hack, KyberSwap had approximately $80 million in TVL.

Shortly after the attack, the thief sent a message: "Negotiations will start in a few hours when I am fully rested." The KyberSwap team later responded to offer a 10% bounty, also seeming to praising attacker: "You have done one of the most sophisticated hacks ser. That was high EV and everyone missed it."

HTX (fka Huobi) and Heco Chain hacked for $115 million

Justin Sun confirmed that HTX (formerly Huobi) and its related Heco Chain protocol were hacked for a combined $115 million. It's been a rough few weeks for Sun, whose Poloniex exchange was hacked for around $120 million on November 10, and a rough few months for HTX, which was hacked for $8 million in late September.

HTX suspended withdrawals as they investigated the hack, and wrote that the company would "fully compensate for HTX's hot wallet losses". Security firm Cyvers said they believed the theft was enabled by a private key leak.

Binance fined over $4 billion, founder pleads guilty and resigns

Binance founder Changpeng "CZ" Zhao pleaded guilty to money laundering charges and agreed to step down as CEO of Binance, the largest global cryptocurrency exchange. He will pay a $50 million fine and faces the possibility of 18 months in prison.

Binance agreed to pay $4.3 billion in restitution for widespread wrongdoing including failure to implement proper anti-money laundering programs, unlicensed money transmitting, and sanctions violations. Binance will be allowed to continue operating, but will be subjected to a three-year-long monitorship program to ensure AML and sanctions compliance.

Simultaneously with the DOJ action, Binance reached agreements with the CFTC, FinCen, and OFAC on ongoing legal issues. Notably, the SEC lawsuit was not among those settled.

CZ posted a long thread on Twitter, admitting "I made mistakes, and I must take responsibility," carefully sidestepping mentioning what any of those mistakes were.

Aragon DAO votes to sue its founding team

Aragon is a prominent project that creates DAO infrastructure. Ironically, its own DAO-based governance has been fraught, with the group facing a governance crisis in May over conflicts between the DAO and the Aragon Association (a small group of "stewards" for the project).

Now, after the Aragon Association decided without consulting the DAO to dissolve itself and wind down the project's governance tokens (while keeping some of the funds), the DAO has voted to sue the group. The DAO has accused the group of improperly taking investors' money to put it "into their new secretive company". They've allocated $300,000 to legal efforts.

Bittrex finally closes up for good

After paying a then-record $29 million fine for sanctions violations in October 2022, shutting down US operations in March 2023, filing for bankruptcy in May, and paying $24 million to settle a lawsuit from the US SEC in August, Bittrex is finally throwing in the towel. The company announced that it was closing its global operations, and urged customers to withdraw funds stored with the exchange within only two weeks. The also informed customers who held US dollars on the exchange that they would not be allowed to withdraw, and would have to convert their dollars to Euros or cryptocurrency.

Bittrex used to be a major player in the US cryptocurrency market, with over 20% of US market share in 2018. However, the exchange's dominance had dwindled to below 1% as of 2021.

DOJ reportedly seeking $4 billion resolution to Binance investigation, with possible criminal charges against CEO

According to Bloomberg, ongoing negotiations between the U.S. Department of Justice and Binance have involved penalties greater than $4 billion as part of ending an ongoing, multi-year probe into the exchange. Such a settlement would not insulate founder Changpeng "CZ" Zhao from criminal charges.

The negotiation may involve a deferred prosecution agreement, in which the US would file a criminal complaint but agree not to prosecute so long as Binance met agreed conditions under a monitoring process.

It remains to be seen if this is the avenue the DOJ and Binance will go with. A Bloomberg source speculated that a decision could come within the next few weeks.

Kraken sued by U.S. SEC

Kraken is the latest cryptocurrency exchange to face a lawsuit from the U.S. Securities and Exchange Commission. According to the SEC, Kraken violated securities laws by listing tokens like Polygon (MATIC) and Solana (SOL), which the SEC has argued in this and in other lawsuits are unregistered securities.

Furthermore, the SEC claims that Kraken commingled corporate and customer funds, "at times pa[ying] operational expenses directly from bank accounts that hold customer cash."

Kraken's new CEO, Dave Ripley, posted on Twitter that the company "plan[s] to vigorously defend [their] position" that they do not list securities.

DOJ cracks down on $225 million crypto romance scam

At least according to the rather shady Tether stablecoin provider, the U.S. Department of Justice has been working on an investigation into a massive "pig butchering" romance scam and human trafficking operation based out of Southeast Asia.

According to Tether, they "voluntarily fr[oze] approximately 225 million in USDT tokens" in connection to the investigation.

Some romance scammers hoping to lure victims into sending them cryptocurrencies are themselves victims of human trafficking operations, where they are held victim and forced to send such messages.

dYdX insurance fund loses $9 million in apparent attack

Around 40% of the "insurance fund", intended to protect dYdX users from having to backstop other traders' losing trades, was drained in what dYdX CEO described as "pretty clearly a targeted attack against dYdX". An attacker manipulated the market for the Yearn Finance token, which is not normally heavily traded on dYdX, but which experienced a surge in trades around the attack. By taking advantage of flaws in dYdX's risk management, the attacker was able to rack up big losses and then force the dYdX insurance fund to pay out.

Kronos trading firm suffers key breach

The cryptocurrency trading firm Kronos Research announced on Twitter that they had stopped trading while they investigated "unauthorized access of some of our API keys". They claimed that "potential losses are not a significant portion of our equity". They later confirmed the loss at around $26 million.

The Blockchain Group suspends stock trading in apparent financial crisis

French blockchain firm The Blockchain Group announced that they had requested trading be halted on the company's shares and postponed a planned company meeting. The announcement disclosed "financial difficulties" that had caused the company to try to obtain rescue financing. They also said that they had begun discussions with creditors around possible restructuring.

The Blockchain Group is behind a number of different services, including a crypto wallet called Eniblock and an open source software bounty project called Bountysource. Users of the Bountysource project have been complaining about issues receiving payments since as far back as May 2023.

Network of fake Twitter accounts impersonating crypto security firms phish panicked victims

A screenshot of Twitter's trending topics sidebar, showing that #OpenSeaSecurityBreach, #OpenSeaHackAlert, and #CryptoSafetyConcerns were trendingTwitter trending topics on November 14 (attribution)
On the evening of November 14 I logged on to Twitter to notice that #OpenSeaHackAlert and related hashtags were trending. But they were trending not because OpenSea had truly been hacked, but because a huge network of fake accounts with usernames similar to those of PeckShield, CertiK, and zachxbt — well-known accounts that alert crypto traders to possible scams — were spamming the hashtag. Hoping to spark panic into crypto holders who had used the popular service, as well as other services like Uniswap which they were claiming were breached, the phishers shared links to sites that would supposedly help users revoke access to their wallets by those services, securing their assets. Instead, however, those malicious sites would drain the wallets.

According to researcher zachxbt, who himself was one of the impersonated, the scammers have stolen more than $300,000 in various assets using this technique.

This is not the first time such a technique has been used — a scammer attempted a similar, though less successful, scheme in April 2022. Scams like this take advantage of the poor UX in the crypto world for tracking and revoking wallet permissions that have been granted, requiring people to use third-party websites created for this purpose. Some of them are legitimate, but there are many malicious copies of these revocation sites that prey upon users who may be acting quickly in fear that their assets are at risk.

Up to $1 billion stored in early Bitcoin wallets may be at risk due to "Randstorm" vulnerability

While trying to help a Bitcoin holder who lost their password, researchers at Unciphered discovered a major flaw in the way early Bitcoin wallets had been created. Thanks to a flaw in an open source software library called BitcoinJS, which was later incorporated into many wallet software projects to generate Bitcoin wallets with random keys, wallets created prior to 2016 may be vulnerable to cracking. Wallets created before March 2012 are at particular risk, as the roughly 6% of those that are vulnerable (and which hold a combined ~55,000 BTC, or ~$100 million) could be cracked without requiring major computing resources.

Unciphered worked with various wallet providers to contact people whose wallets may be vulnerable, though ultimately it is up to those wallet holders to secure their funds by creating new wallets and transferring their tokens. Unciphered also noted that some Dogecoin, Litecoin, and Zcash wallets may be vulnerable due to shared code.

Wallet drainer steals more than $60 million in six months

A wallet drainer service has facilitated the theft of more than $60 million in various assets from almost 100,000 victims since May 2023. According to research group ScamSniffer, the drainer has recently started using functionality in the Ethereum network called CREATE2 to generate new addresses for each malicious signature. This allows the drainer to sidestep security alerts built into some crypto wallet software that would flag known malicious addresses.

ScamSniffer identified one victim who lost almost 17,000 GMX (~$927,000) to this drainer after signing a malicious transaction.

Wallet linked to Binance deployer loses $27 million in apparent hack

An attacker apparently stole $27 million in the Tether stablecoin from a wallet that had just withdrawn the funds from their Binance account. The hacker quickly converted the funds to evade attempts at freezing the stolen assets.

Crypto researcher zachxbt observed that the wallet targeted for the theft had in 2019 received a transfer from the Binance deployer, suggesting that the compromised wallet may have some ties to Binance itself.

Raft exploited for $3.3 million, then hacker screws up

An attacker exploited the Raft defi project after finding a vulnerability that allowed them to mint 6.7 million of Raft's R stablecoin without any backing.

The attacker then went to convert the R into ETH, which they would then be able to launder and cash out. However, an error in the attacker's code caused 1,570 ETH ($3.25 million) to be sent to the burn address, rendering it permanently inaccessible to everyone including the hacker. Only 7 ETH remained. However, because they had to spend ETH to fund the attack, the hack ultimately resulted in a loss of 4 ETH (~$8,000) for the perpetrator. Oops.

As a result of the hack, the R stablecoin lost its dollar peg, plummeting down to around $0.70. Raft acknowledged the attack and announced that they had paused minting.

Poloniex hacked for more than $120 million

Assets including Bitcoin, Ethereum, and Tron's TRX token, priced at more than $126 million, were stolen from Justin Sun's Poloniex cryptocurrency exchange. Researchers are still homing in on the exact amount of funds that were stolen from the company's hot wallets across multiple blockchains, but suffice to say it's a lot.

Poloniex was initially tight-lipped, posting on Twitter that they had "disabled for maintenance" an exchange wallet. Justin Sun later updated that they were investigating the "hack incident", and promised to "fully reimburse" the massive theft... somehow. He later tweeted that they would offer a 5% "bounty" to the hacker if they returned the funds within a week, threatening to "engage law enforcement" otherwise.

CoinSpot exchange exploited

The Australian cryptocurrency exchange CoinSpot appears to have been hacked for around 1,283 ETH (~$2.4 million). In two separate transactions, the ETH was transferred out of CoinSpot's hot wallet, then bridged to Bitcoin via Thorchain and another bridge.

Wintermute declares friendship over with Near Foundation and Aurora Labs after they refuse to send $11 million

"Public service announcement or 'how we are not really friends with Near Foundation and Aurora Labs going forward'", wrote Wintermute CEO Evgeny Gaevoy on Twitter. He launched into a thread accusing Near and Aurora of refusing to honor a previous agreement to facilitate the redemption of around 11.2 million USN, the de-pegged stablecoin of the Near network. Wintermute said they had helped FTX to sell that quantity of the USN tokens, providing them with dollars to disburse to creditors, under the belief that Near and Aurora would help them honor the USN redemptions at $1.

However, Near later decided it would not honor the redemption, accusing Wintermute of trying to pull off an arbitrage trade with the distressed asset. They also, somewhat curiously, claimed that the funds that were provided to Wintermute by the FTX estate may have been the tied to illegal activities. Aurora also described Wintermute's claims as "unfounded", and accused Wntermute of "tr[ying] to exploit the programme to profit from the purchase of distressed assets from the Alameda estate".

Wintermute has promised to "pursue all legal avenues" against the Near Foundation and Aurora Labs.
