Iranian intelligence (MOIS) behind LA Metro hack disguised as 'Ababil of Minab' hacktivists - hundreds of terabytes wiped

Israeli firm Gambit Security has forensically linked the late-March attack on the Los Angeles County Metropolitan Transportation Authority to Iran's Ministry of Intelligence and Security (MOIS), despite the attackers branding themselves as the pro-Iran hacktivist collective 'Ababil of Minab.' The group posted videos claiming it wiped hundreds of terabytes and stole over a terabyte of files. LA Metro confirmed the breach on April 2, 2026, and had to check hundreds of servers for compromise before bringing them back online. The case illustrates a recurring pattern of state operations wearing a hacktivist costume to provide deniability while targeting critical infrastructure.

Check
Critical-infrastructure and transit operators: treat 'hacktivist' claims of destructive attacks as possible state-operation cover. Hunt for wiper precursors and bulk-deletion activity. Validate offline backup integrity.
Affected
US critical infrastructure, especially transit authorities. Iran's MOIS uses fake-hacktivist fronts (here, Ababil of Minab) to claim destructive attacks while preserving deniability.
Fix
Maintain tested offline backups resilient to wipers. Segment OT/IT networks. Monitor for mass-deletion and destructive commands. Coordinate with CISA and ISACs on Iranian APT indicators.

Iran-linked MuddyWater (Seedworm) spent a week inside a major South Korean electronics maker - DLL sideloading off Fortemedia audio and SentinelOne binaries, ChromElevator credential theft

Symantec's Threat Hunter Team detailed a global cyber-espionage campaign by MuddyWater (a.k.a. Seedworm, Static Kitten, Temp Zagros), an APT linked to Iran's Ministry of Intelligence and Security. The group hit at least nine organizations on four continents in Q1 2026 - including a major unnamed South Korean electronics manufacturer where attackers maintained access from February 20 to 27. They abused signed legitimate binaries fmapp.exe (a Fortemedia audio utility) and sentinelmemoryscanner.exe (a SentinelOne component) to sideload malicious DLLs called fmapp.dll and sentinelagentcore.dll, both carrying the ChromElevator post-exploitation tool that lifts data from Chrome-based browsers. Stolen files were staged through public file-transfer service sendit[.]sh to blend in.

Check
Hunt endpoints for fmapp.exe or sentinelmemoryscanner.exe loading non-standard DLLs, search proxy and DNS logs for connections to sendit[.]sh from non-IT users, and review Chrome profile access patterns from sideloaded DLL contexts.
Affected
High-tech manufacturing, electronics, industrial firms, financial services, and government agencies with intellectual-property or downstream-customer value to Iran. Operations in Asia and the Middle East are most exposed, but victims span four continents.
Fix
Add detection rules for fmapp.dll and sentinelagentcore.dll in unexpected paths, block sendit[.]sh outbound where it has no business need, watch for unusual Node.js process trees spawning cmd.exe, and review LSASS access events around the 90-second beaconing window.
