Midnight Blizzard and the 'CaptiveCrunch' Campaign Targeting Microsoft 365 via Hotel WiFi
The "CaptiveCrunch" campaign, attributed to the Russian state-sponsored actor Storm-2945 (a Midnight Blizzard sub-cluster), targets global travelers by compromising hospitality WiFi gateways. The attack utilizes DNS hijacking and poisoning to redirect users from legitimate captive portals to malicious, Microsoft-themed phishing sites. This redirection facilitates two primary objectives: the theft of Microsoft 365 credentials through OAuth token interception and the deployment of the CornFlake Remote Access Trojan (RAT). CornFlake enables persistent endpoint surveillance, including keystroke logging and audio/visual interception. This sophisticated operation, active since May 2026, represents a high-severity threat to enterprise users traveling internationally.
