Submission + - Ledger confirms spy chip implant behind wallet crypto thefts (bleepingcomputer.com)
AmiMoJo writes: Ledger has confirmed that some of its devices distributed through Southeast Asian reseller CryptoBilis were compromised with a hardware implant that drained users' cryptocurrency wallets. The company has been investigating reports of users losing funds from wallets purchased through CryptoBilis, a major Malaysia-based hardware wallet retailer operating across Southeast Asia. Some researchers have shown the implant in Ledger X since September 16, saying tampered devices were available for nearly half the price of the original hardware.
"Under the battery and antenna sits an ST STM32G431KBU6 (Arm CortexM4, 128 KB flash, UFQFPN32)," the researchers found inside one of the devices. For connectivity, the actor used "a tiny eSIM, an 8pad package just 2×2 mm, next to the MCU, and a shielded LTE module that sends the words out."
