An attacker apparently discovered a reentrancy bug allowing them to drain user funds from those who had approved the old contract. Altogether, around $1.8 million was taken before the team disabled the contract. The attacker quickly tumbled the stolen funds through Tornado Cash.
Dolomite exchange exploited for $1.8 million
The Dolomite DEX suffered a $1.8 million theft as an exploiter was able to take advantage of a vulnerability in a smart contract that had been deployed in 2019. Although most contemporary users of the exchange use a version deployed on the Arbitrum layer-2 network, the old contracts were still usable on Ethereum.
SEC launches investigation into Ethereum Foundation
Fortune reported that the U.S. Securities and Exchange Commission has targeted the Swiss-based Ethereum Foundation for investigation, apparently in an effort to classify its ETH token a security. The report came out shortly after CoinDesk reported that a warrant canary had been removed from the Ethereum Foundation's website.
Although the SEC has agreed that bitcoin is a commodity and not a security, it has been hesitant to make similar explicit statements about ETH. Designation as a security could be devastating to the Ethereum project and to ETH, which is the second most popular cryptocurrency to bitcoin.
Bitcoin flash crashes on BitMEX
A "very small number of accounts" were able to crash the bitcoin price on the BitMEX exchange from its roughly $66,000 price to as low as $8,900. BitMEX attributed the incident to "aggressive selling behavior" by that small group.
The incident underscores the thinness of the bitcoin markets on some cryptocurrency exchanges, and the ease with which a few whales can manipulate token prices.
BitMEX used to be among the largest cryptocurrency trading platforms, though its popularity diminished after its founders were hit with criminal charges in 2020 for violations of the Bank Secrecy Act.
Slerf memecoin meltdown only adds to mania
People have gotten really into memecoin trading on Solana recently. Like really into it. Someone decided they'd hop on the bandwagon with "Slerf", a sloth-themed memecoin they said would launch with a 50% presale.
Thanks to the aforementioned frenzy, the project managed to raise $10 million in the presale. However, things went sideways when the developer accidentally burned the $10 million by sending them to an address where they would be permanently inaccessible. "oh fuck", the developer wrote ominously on Twitter, before explaining their mistake.
Some speculated that the screwup may have been a marketing ploy, in which case it was very successful, because the token went on to post more than $2.7 billion in trading volume over a 24-hour period — more than the entire ETH trading volume in that period. The monumental error by the developers seemed to have no damper on the overall frenzy around memecoins, or even produced the opposite effect.
Surely this trend won't end badly.
Wilder World game suffers $1.8 million theft, blames contractor
Wilder World is a blockchain-based racing game that uses all the buzzwords: blockchains, artificial intelligence, and metaverse. On March 16, someone with access to the project deployer's private key upgraded legacy contracts and transfer the project's $WILD and $MEOW tokens to themselves. Altogether, the attacker profited 515 ETH (~$1.8 million), which they then laundered through the Tornado Cash cryptocurrency tumbler.
The project blamed the theft on a previous contractor who had the private key. They also explained that the attacker seemed to be a developer based on the fact that they had "specialized knowledge of ZERO's internal security systems".
Phisher impersonating influential crypto trader in Twitter replies scams over $2.6 million
![Tweet by real Ansem account: i dont launch coins bros, but i can give allo to good stuff in other ways soon
Tweet by fake Ansem account closely resembling the one above it:
im about to launch my own token $BULL this weekend
link presale: [redacted link]
min 1 sol
max 3 sol
lets run it up yall](https://primary-cdn.web3isgoinggreat.com/entryImages/resized/ansem-impersonator_300.webp)
Someone impersonating Ansem, an influential crypto trader, was able to scam people out of more than $2.6 million simply by replying to the real Ansem's tweets. Using an account mimicking the real account, with only a slight difference in the username, a phisher convinced Ansem's followers that he was creating his own Solana memecoin and asked them to buy in.
In one of the real Ansem's tweets, Ansem wrote "i dont launch coins bros" — nevertheless, followers eager to get in early on a new memecoin clicked a link offering a presale and had their wallets drained.
Altogether, people lost $2.6 million to the scam. One individual lost $1.2 million.
Remilia Collective reports multi-million dollar hack
"Charlotte Fang", the leader of the controversial Remilia project (known for its Milady NFTs), claimed he was hacked and drained of ETH and NFTs potentially worth several million dollars. Although the project's treasury used a multi-signature model, the private keys were stored in one password manager, which Fang says was compromised.
The attacker stole around 490 ETH (~$1.8 million) and $58,000 USDC, along with more than 130 Milady NFTs, 320 Remilio NFTs, and hundreds of derivative tokens issued on the NFTX platform. Based on floor prices, the assets are valued at north of $6 million.
The mechanism of the attack is still uncertain, though Fang has said he suspects malware that could have intercepted credentials to his Bitwarden password manager. Some have expressed skepticism around the "hack", suggesting it could have been inside job. The Remilia group had suffered a separate $1 million loss in September 2023 — blamed on a rogue developer — and failed to implement many security safeguards after that incident.
NFPrompt discloses hack
A Binance-incubated platform called NFPrompt claims to be "the first Prompt Artist Platform in Web3" — with "prompt artist" referring to people who come up with prompts to feed into large language models. More succinctly, it's a platform to sell the NFTs you've made out of AI-generated images.
The platform announced on March 15 that it had suffered a "critical security incident" that it attributed to "a group of hackers" who were able to gain access to funds belonging both to the project's users and the project itself. They did not disclose how much was taken.
The project announced that it was working with the FBI, and had contacted centralized exchanges to ask them to freeze stolen funds.
Someone accidentally burns $1.36 million Tether
Someone accidentally threw away $1.36 million when they accidentally sent Tethers to the Tether contract address — making them permanently inaccessible in a process known as "burning". This is a rather common phenomenon in crypto, where it's easy to accidentally copy/paste the wrong address.
Most experienced crypto users have adopted the habit of sending small test transactions before transferring large amounts of tokens, to first check that they're using the correct address. Oddly, this person did so in this case, but then went right ahead and transferred the remaining tokens to the erroneous address.
The person may have lucked out that they were using a centralized stablecoin like Tether, whose operators hold a substantial amount of control over freezing, destroying, and creating new Tethers — and could feasibly replace the burned tokens.
Mozaic exploited for $2 million, recovers 90%
The "AI-optimized" defi project Mozaic Fi was exploited by an attacker who drained around $2 million in funds from the project.
According to MozaicFi, the theft had been perpetrated by a rogue developer who was able to gain access to a private key held by a core team member. They also claimed that a simultaneous large sale of the Mozaic token resulted in cascading liquidations.
In good news for the project, the attacker moved around 90% of the stolen funds to MEXC, a centralized cryptocurrency exchange that was able to freeze the thief's access to the funds.
