Augur Reports Iranian APT Infrastructure Buildup Before Epic Fury

Summary
Augur Security says Iranian-linked groups expanded infrastructure activity before the February 2026 US-Israeli strikes, while an estimated 60-plus hacktivist groups coordinated cyber activity afterward.
Key points
- Augur reports increased infrastructure activity among several MOIS- and IRGC-linked groups in the six months before the February 28, 2026 strikes.
- Augur assessed that MuddyWater's September 2025 infrastructure spike was consistent with pre-operational staging, with medium confidence that it was preparation for post-strike operations.
- The report describes multi-tier infrastructure involving an Iranian ISP, bulletproof hosting providers and additional shell-company layers.
- The report says an Electronic Operations Room formed within 24 hours of the strikes to coordinate an estimated 60 or more hacktivist groups.
- Reported targets were primarily Israeli and US government, financial and critical-infrastructure organizations, with Gulf states described as a secondary focus.
- The article says damage to Iran's internal internet connectivity did not seriously affect Iranian APTs' ability to continue and expand operations.
Article Details
- Event Type
- Reported preparation and expansion of Iranian-linked cyber operations before and after the February 28, 2026 US/Israeli strikes against Iran, including increased infrastructure activity and coordinated hacktivist activity.
- Impact
- Augur Security reported increased infrastructure activity by government-linked Iranian groups in the six months before the strikes and a rapid post-strike expansion of hacktivist activity, with an estimated 60 or more groups coordinated through an Electronic Operations Room. Reported targets include Israeli and US government, financial, and critical-infrastructure organizations, as well as Gulf states described as facilitating the strikes. Augur assessed with medium confidence that MuddyWater’s infrastructure buildup was preparation for post-strike operations. The article says the strikes damaged Iran’s internal internet connectivity but did not seriously affect Iranian APTs’ ability to continue and expand cyber operations.
