$35 million stolen in attacks on Atomic Wallet cryptocurrency customers

More than $35 million has been stolen from Atomic Wallet, a decentralized cryptocurrency wallet platform supporting more than 500 coins and tokens.

On Saturday, the company confirmed reports that users’ wallets were compromised and said it was investigating the situation.

In an update on Sunday, the company posted a statement on Twitter saying “less than 1%” of their monthly active users were affected by the incident and that the theft appears to have stopped at some point on Friday or Saturday.

Officials said they were reporting victim addresses to major exchanges and blockchains in order to trace and block the stolen funds from being moved.

In a statement to Recorded Future News on Monday, Chief Marketing Officer Roland Säde said the investigation is still ongoing so he was unable to speak at length about what happened.

He urged customers to report their stolen funds to the relevant exchanges.

“Of course on our side we are also doing that with the help of external companies, however, the more eyes the better,” he said, declining to answer further questions about whether law enforcement had been contacted,if victims would be made whole, and how much had been stolen.

ZachXBT, a cybersecurity expert and cryptocurrency security researcher, tracked losses connected to the incident and said they totaled more than $35 million.

Hugh Brooks, director of security operations for CertiK, said blockchain analysis showed that around $35 million was indeed stolen.

“How the attack took place is currently unknown but it's likely due to a bug in the wallet providers application that exposed users private keys,” Brooks said, adding that the size of the theft makes this incident stand out.

“Slope (Solana wallet provider) users were impacted by a private key breach resulting in ~$8m lost in 2022, as well as MyAlog users which saw ~$9.2m lost in February this year. This event easily surpasses these two previous incidents combined,” he said.

Dozens of people flooded Twitter to report losses, some reaching millions of dollars.

Atomic Wallet has urged customers to either contact them or fill out a form about what was stolen. The wallet is available on Windows, Android, iOS, macOS, and Linux.
