MetaMask announced that more than 7,000 users were at risk in a recent hacking operation. According to a MetaMask developer, a sophisticated hacker used an unknown attack method to dump millions of dollars worth of altcoins.
This altcoin was looted in the mysterious MetaMask heists
MetaMask developer @tayvano_ reports that more than 5,000 Ethereum (ETH) and an indefinite amount of tokens and NFTs have been stolen across multiple networks in an ongoing attack since late last year.
The developer added that he has been investigating the operation for the past two days but cannot determine how the attacker committed the thefts: “I’ve been solving a large wallet emptying operation for the past 48 hours. I don’t know how big it is but since December 2022 there are more than 5000 ETH countless tokens.”
Experienced names targeted
The developer pointed out that the attack was a complex attack that deliberately targeted senior Ethereum developers and personalities, noting that no one can figure out how my hack happened. Forensic device examination also yielded no results.
The commonalities between the cases were that the keys were generated between 2014 and 2022 and that the victims were “crypto natives” such as having multiple addresses and working in the crypto industry.
Advice for altcoin investors’ safety
@tayvano_ speculates that hackers got a cache of data from the victims’ device. Using this, they can abstract MetaMask keys – but he stresses that this is “just a guess”: “My best guess is that someone has a greasy cache of data from 1+ years ago and methodically dumped the keys while parsing them from the treasure trove. “
The developer warns MetaMask users to avoid storing all their cryptocurrencies in a single wallet key. Instead, cryptos should split into multiple keys or keep assets in a hardware wallet.
