$330 million in Bitcoin apparently stolen; laundering spikes Monero price by over 40%

3,250 BTC (~$330 million) were apparently stolen from a bitcoin holder and then quickly moved through multiple exchanges and swapped for the Monero privacycoin. Such a massive swap into Monero was apparently enough to cause the Monero price to spike from around $230 to as high as around $330, before retracting somewhat.

Loopscale hacked for $5.8 million two weeks after launch

A new Solana-based defi protocol called Loopscale, backed by Coinbase Ventures and Solana Labs, suffered a $5.8 million exploit only two weeks after its launch. The stolen funds represented 12% of the protocol's TVL. The project blamed the exploit on a bug in the protocol's pricing calculations. Although the project had been audited in February by OShield, the audit evidently did not detect the flaw.

$5 million in tokens stolen from ZKsync

An attacker compromised an admin account belonging to the ZKsync Ethereum layer-2 project, which is built by Matter Labs. By doing so, they were able to steal approximately $5 million worth of the ZK token, which the project said were "the remaining unclaimed tokens from the ZKsync airdrop".

ZK Sync offered a 10% "bug bounty" to the thief, who accepted and returned 90% of the stolen funds.

KiloEx exploited for $7.5 million

KiloEx, a decentralized perpetual futures exchange, was exploited for $7.5 million. An attacker executed an oracle manipulation attack on KiloEx's pricing smart contracts to steal funds across the Base Ethereum layer-2 chain, BNB Chain, and Taiko.

KiloEx halted trading on the platform while investigating the exploit, and contacted the hacker to try to negotiate a 90% return of funds.

KiloEx later announced that the recovery had been successful, and that they would pay out the 10% "bounty".

zkLend thief gets robbed

The zkLend lending platform was hoping they could secure the return of stolen funds from the attacker who stole 3,667 ETH (~$9.5 million at the time) from the platform in mid-February. They offered a 10% "bounty" for the return of the funds, but received no reply — that is, until now.

On March 31, the attacker sent an on-chain message to the platform, writing: "Hello I tried to move funds to tornado but I used a phishing website and all the funds have been lost. I am devastated. I am terribly sorry for all the havoc and losses caused. All the 2930 eth have been taken by that site owners. I do not have coins. Please redirect your efforts towards those site owners to see if you can recover some of the money. I am sorry."

The zkLend project instructed the thief to return any remaining funds to their wallets, though no such transfer has happened yet.

There has been substantial conversation over whether the hacker had truly been in turn scammed out of the stolen funds, had made up a fake phishing site to try to obscure the path of stolen money, or perhaps whether the whole event had been an April Fools' joke. However, zkLend noted on Twitter that the phishing website, which imitates the Tornado Cash platform, has been operational for five years and is likely not connected to the hacker.

Coinbase customer loses $35 million in bitcoin theft

A Coinbase customer reportedly lost 400 BTC (~$35 million) in a scam identified by blockchain sleuth zachxbt. While investigating the massive theft from the single customer, he also observed at least $11 million in thefts from various other Coinbase customers throughout March.

zachxbt has previously accused Coinbase of not doing enough to protect customers from hundreds of millions of dollars in scams, and he noted that in these cases, Coinbase had not marked the thief wallets as malicious in various cryptocurrency compliance tools.

Abracadabra loses $13 million in "Magic Internet Money"

An attacker using a flash loan attack stole $13 million in the Magic Internet Money token from the Abracadabra project. The attack was enabled by a bug in the platform's smart contracts, and the hacker ultimately made off with around 6,262 ETH.

This is the second time Abracadabra has been exploited, after suffering a $6.5 million theft in January 2024.

Zoth hacked for nearly $8.3 million, second theft in two weeks

RWA restaking platform Zoth suffered a $8.29 million hack after an attacker gained access to admin privileges that allowed them to modify the platform's smart contracts. The hacker "upgraded" the contract to a malicious version, then withdrew $8.45 million in USD0++, a token issued by the Usual protocol. After swapping the assets into various other tokens, they were left with 4,223 ETH (~$8.29 million).

This is the second Zoth exploit in two weeks, following a $285,000 theft on March 6 by an attacker who took advantage of a bug in one of the platform's smart contracts.

Four.Meme suffers second hack in as many months

After suffering an $183,000 loss to an attack in February, the BNB-based Four.Meme memecoin launchpad has been hacked again, this time for around $130,000. Four.Meme aims to be BNB's version of pump.fun, the popular Solana-based memecoin platform.

Four.Meme acknowledged the latest theft on Twitter, writing that they intended to reimburse users who lost money.

Zoth RWA restaking platform hacked

Zoth, a restaking platform for "real world assets" (or RWAs), was hacked for around $285,000 when an exploiter discovered a bug in the platform's collateral calculations. This allowed them to mint ZeUSD, the platform's stablecoin token, without depositing sufficient collateral.
