A mysterious and sophisticated crypto wallet heist has drained up to 5,000 Ethereum, currently worth almost USD 10 million, from "OG" wallets, baffling security experts and blockchain enthusiasts.
The malicious operation was uncovered by Taylor Monahan, founder and CEO of ETH wallet manager MyCrypto and former MetaMask employee. Reportedly, the lengthy heist has been active since December 2022 and has targeted ETH tokens and other coins and NFTs across more than 11 crypto chains.
The term "OG" wallet refers to early adopters of cryptocurrency and blockchain technology, who often hold a significant amount of assets. The wallets’ high value and the potential for substantial financial gain make them prime targets for cybercriminals.
While the exact method used by the attackers remains unknown, preliminary research suggests the heist may exploit a previously undiscovered vulnerability or used private keys from an older data leak.
The attackers seem to have covered their tracks well, making it difficult for investigators to pinpoint their origin and identify the victims’ sources of compromise. According to Monahan’s tweet, the only “known commonalities” are that the keys were created between 2014 and 2022, and the perpetrators focus exclusively on high-profile, “crypto-native” users.
On the other hand, the crooks follow a highly distinctive pattern to carry out their operation:
In the original thread, Monahan hinted that the massive wallet-draining heist may have stemmed from a MetaMask exploit, but the company has since responded that Monahan’s claim was wrong. MetaMask’s announcement adds that the crypto assets were drained from “various addresses across 11 blockchains,” not solely from MetaMask wallets.
The theft has raised serious concerns among the crypto community. The scope of the attack and the number of affected chains indicate that even well-established projects and trustworthy wallet providers may be vulnerable to exploitation.
Users should remain vigilant and follow best security practices, such as keeping their private keys and recovery phrases secure, using hardware wallets, and enabling multi-factor authentication wherever possible.
This heist serves as a stark reminder of the risks associated with digital assets and the importance of maintaining strong security measures to protect investments. The crypto community is encouraged to stay informed and exercise caution to minimize the risk of falling victim to such malicious campaigns.
