Hijacked Hotel Wi-Fi Pushes Fake Updates to Deliver Surveillance Malware

3 Actors

AI Summary

A threat actor dubbed Storm-2945, assessed to be a sub-cluster of the Russian state-sponsored group APT29 (aka Cozy Bear), has hijacked hotel Wi-Fi networks to deliver a surveillance-focused remote access trojan named CornFlake. The attack abuses compromised captive portals to redirect users to fake browser or OS update prompts, which lead to the download of malicious payloads. The CornFlake malware, written in Go, establishes persistence via registry run keys and scheduled tasks, captures keystrokes, screenshots, microphone audio, and browser credentials, and can bypass Chrome's App-Bound Encryption. A related in-memory PowerShell stealer, ChocoShell, harvests Microsoft 365, Azure AD, and WAM tokens from the Token Broker cache. Attackers also leveraged Microsoft's device code authentication flow to gain MFA-satisfied access by tricking users into approving malicious sessions.
