Blockchain security experts uncovered a malicious mobile app that stole sensitive wallet knowledge from customers’ devices, leading to the theft of over $1.8 million in cryptocurrency.
A false app called BOM stole over $1.82 million in crypto by secretly gaining access to customers’ non-public keys and mnemonic phrases, in accordance to blockchain security firms SlowMist and OKX Web3 Security. In a Feb. 27 study memoir, SlowMist reported that the first unauthorized transactions with the app were seen on Feb. 14.
On-chain analysis confirmed identified main leaks, which ended in additional revealing that BOM modified into as soon as truly a scam app luring victims into giving file access. As soon as granted, the app scanned system storage, took wallet knowledge, and sent it to a remote server.
The app requested for pointless permissions, delight in access to photos and media, what security experts called a “highly suspicious” behavior.
“On iOS, the app first requests permissions, deceiving customers with a message claiming the access is fundamental for normal operation. This behavior is extremely suspicious — as a blockchain-related application, it has no respectable reason to require access to the photograph gallery.”

SlowMist tracked stolen funds across extra than one blockchains, estimating that the first hacker address (0x49aDd3E…) stole resources from at the least 13,000 victims and transferred the funds through BNB Chain, Ethereum, Polygon, Arbitrum, and Coinbase’s Harmful.
The stolen crypto incorporated Tether (USDT), Ethereum (ETH), Wrapped Bitcoin (WBTC), and Dogecoin (DOGE).
Whereas it’s unclear who is leisurely the procedure, SlowMist analysts identified that the app’s backend services were offline in some unspecified time in the future of research, suggesting the attackers are already making an strive to duvet their tracks. Some funds were swapped on decentralized alternate platforms similar to PancakeSwap and OKX-DEX.
