SlowMist researchers have linked the FomoPeek iOS app to the theft of approximately $580,000 in USDT. The firm identified that versions 1.1 and 1.2 of the app exploited vulnerabilities in the iOS kernel, allowing it to bypass the sandbox restrictions and gain unauthorized access to Keychain and files from other applications. This investigation, conducted in collaboration with the security team at OKX, was prompted by user complaints. Notably, version 1.3, released on September 17, has been reported to be free of malicious elements.
