Crypto wallet maker Atomic Wallet reported a large-scale hack on Saturday, June 3, after receiving reports about compromised crypto wallets. Atomic said on Twitter it has opened an investigation into the issue, adding it would share more information accordingly.
A day later, pseudonymous on-chain researcher ZachXBT said that according to his findings, the total amount stolen from Atomic wallets exceeded $35 million. The largest victim of the hack was identified on the Tron blockchain, who lost 7.95 million USDT in the attack.
The five largest targets account for $17 million in stolen funds, ZachXBT added.
Replying to one of the comments, the blockchain investigator said he believes the total amount of stolen crypto in the hack could surpass $50 million as he keeps “finding more and more victims.”
According to crypto security research Tay, the earliest transaction for stolen funds from the Atomic Wallet occurred on June 2, at 21:45 UTC.
Atomic Wallet says less than 1% of monthly active users affected
On Monday, June 5, Atomic also posted an update, saying that “less than 1% of our monthly active users have been affected/reported” at the moment. “Last drained transaction was confirmed over 40h ago.”
Atomic developers also took down their download server, ‘get.atomicwallet.io,’ due to concerns that their software might have been exploited.
Meanwhile, the popular crypto news account whalecharts said that the hack was allegedly made possible due to a “malicious update” that transferred users’ private keys to the perpetrator once they open the app.
However, the cause of the attack is yet to officially be confirmed by Atomic Wallet.
