A significant portion of the approximately $573,000 stolen from the multichain token bridge Allbridge has been returned after the exploiter appears to have accepted the project’s offer of a white hat bounty and no legal retaliation.
On April 3, Allbridge tweeted that it had received a message from an individual, and that 1,500 BNB $309, worth approximately $465,000, had been returned to the project. “The remaining funds will be treated as a white hat bounty for this individual,” Allbridge explained.
It explained that all “received BNB” was then converted to the Binance USD $1.00 stablecoin to be used as compensation.Peckshield, a blockchain security firm, first identified the April 1 attack, warning Allbridge in a tweet that its BNB Chain pools swap price was being manipulated by an individual acting as a liquidity provider and swapper.
Following the exploit, Allbridge offered the attacker a reward and the opportunity to avoid legal repercussions. Allbridge has yet to publicly disclose how much money was stolen, but blockchain security firm CertiK estimated it was close to $550,000, while PeckSheild estimated it was $282,889 in BUSD and $290,868 in Tether $1.00, totaling approximately $573,000.
Allbridge also revealed that a second address used the same exploit and shared a link to a wallet containing 0.97 BNB, which is currently worth around $300.
“We request that the second exploiter contact us to discuss the return,” Allbridge said.
Following the initial exploit, Allbridge made it clear that they were on the hunt for the stolen funds and were collaborating with a wide range of organizations to recover the loot. BNB Chain was among those who responded to the call to arms, tweeting on April 2 that it had discovered at least one of the perpetrators through on-chain analysis.
BNB Chain stated that it is “actively supporting the Allbridge team on the fund recovery,” and praised AvengerDAO for its efforts in the recovery.
Cointelegraph reached out to Allbridge for additional comment, but did not receive an immediate response.
