3Commas finally owns up to API key leak

In October, several people reported losing more than a million dollars each from accounts that were connected to the 3Commas trading platform. 3Commas vociferously denied that there was any security breach of their crypto trading service, instead claiming that some of their users were at fault for being phished and having assets stolen. Now that someone has published the API key database that was exfiltrated from 3Commas, however, the company has finally owned up to the breach. They confirmed the data in the files was legitimate on Twitter, and wrote that they had contacted Binance, Kucoin, and other exchanges with whom they integrate to ask them to revoke all API keys connected to 3Commas.

3Commas did not come off looking very good after this incident, after they spent weeks denying any breach and accusing those who were concerned 3Commas had been compromised of spreading misinformation and "FUD".

Researcher zachxbt wrote that he had verified 44 victims who had lost a combined $14.8 million due to the leak, although he acknowledged that this was only the number of people he could verify and that the total number of people affected was likely much higher.

Midas Investments platform closes after revealing they're $63.3 million in the hole

Midas Investments announced suddenly that they would be shutting down their platform, which previously enabled users to deposit cryptocurrencies which would then be invested in various defi projects. The team revealed that they had only $51.7 million in assets compared to $115 million in liabilities, a fact they had not disclosed to most of their employees.

Users with assets on the platform will see a significant haircut in what they are allowed to withdraw. Midas intends to keep 55% of the Bitcoin, ETH, or stablecoins held by users in their accounts, as well as any rewards users had earned.

Lest the users be too upset that more than half of their assets no longer belong to them, fear not: Midas will be making up the difference in a new, valueless token that does not yet exist, but that will be associated with some future project that Midas has not described yet. You're welcome!

They've also announced they will be pivoting to "CeDeFi". Yes, that is indeed short for "centralized decentralized finance". No, I am not joking.

Mango Markets exploiter arrested despite claiming all his actions were legal

In October, an exploiter was able to manipulate collateral prices to extract tokens from the Mango Markets defi project, ultimately resulting in a $116 million loss for the project. The exploiter then tried to create a governance proposal in which he would agree to return some of the stolen funds in exchange for an agreement that the protocol would not try to freeze the tokens or pursue criminal charges.

It quickly became apparent that a man named Avraham Eisenberg was behind the exploit. In screenshots leaked from a conversation in a private Discord channel shortly before the attack, Eisenberg talked about the exploit he had planned. "I'm investigating a platform that could maybe lead to a 9 figure payday. Should I do it?" he wrote. When someone replied, "unles[s] it is highly illegal", Eisenberg responded: "Are there rules these days?" When someone suggested responsibly disclosing the vulnerability to the protocol, Eisenberg refused, saying the bug bounty was likely to be too small.

Eisenberg later owned up to the attack, tweeting a thread in which he wrote that he "was involved with a team that operated a highly profitable trading strategy last week. I believe all of our actions were legal open market actions, using the protocol as designed, even if the development team did not fully anticipate all the consequences of setting parameters the way they are."

The feds apparently disagreed with his evaluation, and arrested Eisenberg in Puerto Rico on December 26. He is charged with commodities fraud and commodities manipulation.

BTC.com suffers $3 million attack

In a press release, BIT Mining reported that their subsidiary BTC.com had experienced a "cyberattack" in which $700,000 of customer assets were stolen. They also reported that $2.3 million of company assets were stolen, though they said that some of these funds had been recovered. They wrote that they were working with Shenzhen law enforcement to investigate the attack, but provided few details on the attack vector.

BTC.com is the seventh largest Bitcoin mining pool, which also operates other crypto mining services. Its parent company, BIT Mining, is publicly traded on the NSYE.

Millions of dollars of user funds stolen in BitKeep wallet hack

BitKeep, a popular cryptocurrency wallet in Asia, suffered a hack in which at least $8 million in various cryptocurrencies were stolen from user accounts.

BitKeep has claimed that attackers were able to compromise a version of their software and introduce malicious code which enabled them to drain user funds. BitKeep recommended their users contact the team behind BNB Chain on social media to plead with them to freeze an address used by the hackers, although the attackers had already begun to tumble the funds.

This is the second BitKeep-related hack in the last few months. In October, hackers stole more than $1 million worth of BNB when the Swap feature of the BitKeep wallet was exploited.

Rubic cross-chain exchange hacked, $1.4 million in user funds stolen

The Rubic cross-chain exchange suffered an exploit in which attackers were able to siphon a total of around $1.4 million in user funds from their wallets. The exploit was enabled by an error by the project team, who erroneously added the USDC stablecoin address as a router, which allowed attackers to arbitrarily withdraw USDC held by Rubic users. The hacker then transferred the stolen funds through the Tornado Cash cryptocurrency mixer.

Rubic paused their project to limit further thefts, and stated they would pursue audits before coming back online. They also stated that they would "strive to compensate for the losses".

Police arrest two executives of shuttered AAX exchange

The Hong Kong-headquartered AAX cryptocurrency exchange suddenly halted withdrawals on November 13, claiming they were performing temporary system maintenance. However, withdrawals were never re-enabled, and customers quickly realized the exchange was unlikely to resume withdrawals. Some even began searching for the whereabouts of AAX execs, showing up at offices in Hong Kong and Singapore.

Now, Hong Kong police have arrested Liang Haoming and Thor Chan, two executives connected to AAX. Police have reportedly accused the men of using the maintenance excuse to halt customer withdrawals while dealing with a liquidity crisis.

Defrost Finance fails to rug pull

Defrost Finance, a defi trading platform built on the Avalanche Network, apparently tried and failed to rug pull its users. The project claimed on December 23 that they were "sad to announce that our V2 has suffered a hack, with an attacker using a flash loan function to withdraw funds". They later announced that this "hacker" had also managed to exploit the v1 version of their project. Altogether, it appeared that tokens valued at around $12 million had been stolen.

Observers were quick to notice that the "hack" was made possible by the addition of a fake collateral token, which was then manipulated to liquidate the protocol's users, suggesting the "hack" was likely an inside job.

On December 26, Defrost claimed that the "hacker" had miraculously returned the money. The announcement didn't seem to convince the project's users, who left comments like, "It was never hacked. You tried to rug your users".

Defrost Finance's team had previously run a project called FinNexus, which also suffered a "hack" in May 2021 that was widely believed to have been a rug pull.

The latest Pokémon knockoff is stopped in court

Knock-off Pokémon crypto products — including NFTs and blockchain games — have been so prevalent in the past two years that they've earned their own collection on this blog.

Now, it seems that The Pokémon Company International (TPCI) is doing something about it. They hired private investigators to try to locate and serve a company called Kotiota with legal papers, though ultimately were unsuccessful in finding their offices or any employees.

Kotiota was engaged in unusually brazen Pokéfraud, sending legal letters to news outlets who had written about the real Pokémon games and insisting they be named as a developer. Their website falsely claimed Kotiota had been working on various recent Pokémon games, and the company had even forged an agreement with TPCI to claim they had a license agreement.

Kotiota had been planning to release a Pokémon-based play-to-earn blockchain game and collection of NFTs in January 2023, but an Australian court has barred the company from doing so, and ordered them to stop using the Pokémon brand or claiming to have developed the games.

FTX executives Caroline Ellison and Gary Wang plead guilty to criminal charges, are cooperating with investigation

Two of Sam Bankman-Fried's inner circle, Caroline Ellison and Gary Wang, have pled guilty to federal criminal charges and are cooperating in the case against Sam Bankman-Fried. Ellison was the CEO of Alameda Research, the trading firm founded by Sam Bankman-Fried in 2017. Wang was a co-founder of FTX alongside Bankman-Fried, and served as its CTO.

Ellison's and Wang's pleas were announced in a short message by U.S. Attorney Damian Williams, who did not elaborate on what the charges were. He again urged any others who had knowledge of criminal activity at FTX to come forward, and warned that these were not the last charges he expected to file.

Simultaneously with the charges from the Justice Department were civil complaints from the Securities and Exchange Commission, which alleged that both had been involved "in a multiyear scheme to defraud equity investors in FTX". In particular, the SEC accused Ellison of artificially manipulating the price of FTT, the FTX-issued token that formed a large portion of Alameda's balance sheet. The SEC accused Wang of creating a backdoor in FTX software that allowed Alameda to move customer funds from FTX for use in its trading activities.

The CFTC filed an amendment to their complaint against Sam Bankman-Fried, adding Ellison and Wang as defendants.
