DeFi hackers usually transfer the stolen crypto funds to a smart contract, called an “attack contract”, which is then transferred to a wallet while the attack contract self-destructs. In this case, however, the attacker seems to have forgotten to transfer the crypto out of the wallet before setting it to self-destruct.
BlockSec’s researchers noted that $1,041,237.57 worth of stolen crypto tokens are not stuck in the contract forever, since it has been set to self-destruct. The attack took place at 7:15 am UTC on April 21.
To be sure, this doesn’t protect the DeFi platform from losing money. The stuck tokens can’t be recovered, neither by the hacker nor by the protocol itself. But the incident still brings a few chuckles for the serious issue that DeFi hacks have become over the past year or so.
DeFi hacks on the rise
In fact, data from analysis firm The Block Research from November 2021, showed that attacks on DeFi firms had grown by a massive 22.5x year-on-year. According to data from blockchain research company
Notable amongst these are hacks of the Ronin Network, which is attached to Axie Infinity, one of the most popular web3 games in the world today. “In the past, cryptocurrency hacks were largely the result of security breaches in which hackers gained access to victims’ private keys—the crypto-equivalent of pickpocketing. Ronin Network’s March 2022 breach, which enabled the theft of $615 million in cryptocurrency, has proven the continued effectiveness of this technique,” Chainalysis said.
Ronin’s competitor, MetaMask, which is also amongst the most popular crypto wallets in the world, also alerted users of a possible compromise earlier this week.
