Iran-linked threat actors escalated from espionage to disruptive and destructive operations in the wake of the US/Israel military campaign dubbed Operation Epic Fury, with reporting describing a coordinated hybrid offensive against Western, Israeli, and regional economic and critical infrastructure targets. Tenable assessed MOIS-affiliated groups as increasingly masking activity behind cybercriminal infrastructure to complicate attribution, and highlighted a notable rise in Iranian-nexus targeting of internet-connected IP cameras using known, exploitable vulnerabilities; the same reporting pointed to increased activity from MuddyWater and the Void Manticore/Handala persona, including indications of pre-positioned access ahead of the kinetic operations.
Separate threat-intelligence reporting described China-nexus actors rapidly pivoting in the same geopolitical window, including activity against Qatari entities shortly after the initial strikes: Camaro Dragon attempted to deploy a PlugX variant using conflict-themed lures, and another intrusion attempt used DLL hijacking to deliver Cobalt Strike, consistent with China-aligned tradecraft. Other items in the set cover unrelated campaigns and incidents—an exposed APT28 Roundcube exploitation toolkit targeting Ukrainian government mail infrastructure, a pro-Russian NoName057(16) DDoS campaign heavily targeting German and Israeli public-sector and commercial services, a Russian-speaking BlackSanta BYOVD “EDR killer” delivered via HR-themed lures and steganographic images, and a weekly bulletin summarizing multiple breaches (e.g., AkzoNobel, LexisNexis, Wikimedia, TriZetto)—and do not materially add to the Operation Epic Fury–linked escalation narrative.

11 events from the most recent confirmed update back to the earliest known activity.
By March 31, 2026, KELA reported that Iran was reviving the Pay2Key ransomware operation as a state-backed tool against high-impact U.S. targets, including recruiting affiliates from Russian cybercriminal forums. The report also described Iran's use of 'pseudo-ransomware,' including Agrius's Apostle malware, to disguise destructive or wiper-like attacks as financially motivated ransomware.
On March 11, 2026, Check Point Research publicly reported the Qatar-focused Chinese-nexus activity and released indicators of compromise. The company also advised organizations to strengthen baseline defenses such as EDR and MFA.
A recent FBI-led effort deleted PlugX malware from thousands of devices globally. Despite that disruption, Check Point noted that PlugX remains in active use by Chinese-nexus actors.
A separate campaign targeting Qatari entities used password-protected archives and low-quality AI-generated lures impersonating the Israeli government. The intrusion delivered a previously unseen Rust-based loader that hijacked an NVDA component and ultimately deployed Cobalt Strike.
Check Point reported one intrusion attributed to Camaro Dragon against a Qatari entity that attempted to deploy a PlugX variant. The attack used conflict-themed email lures and an infection chain that abused DLL hijacking of a legitimate Baidu NetDisk binary.
Shortly after the first U.S.-Israeli strike in Iran, Chinese-nexus threat actors were observed rapidly pivoting toward Qatari entities. Check Point assessed the near-immediate focus on Qatar as unusual for China-backed groups and potentially tied to intelligence collection during the regional crisis.
Reporting noted increased Iranian-linked exploitation of Hikvision and Dahua IP cameras using known vulnerabilities. Analysts warned this access could support post-strike observation or even kinetic operations.
The Void Manticore persona 'Handala' was reported as claiming a large-scale wipe and data theft incident against Stryker, potentially involving compromise of Microsoft Intune and defacement of Microsoft Entra login pages. The campaign was described as part of a destructive trend using wipers such as BiBi Wiper and Cl Wiper.
In the period after the strikes, MuddyWater was reported as having pre-positioned access and using backdoors including Dindoor and Fakeset, while also conducting the MENA-focused 'Operation Olalampo' using a Telegram bot for command and control. The activity was cited as part of the broader Iranian cyber response.
Following Operation Epic Fury, reporting described Iranian-linked activity moving beyond primarily espionage into more coordinated disruptive and destructive attacks against Western, Israeli, and regional targets, including critical infrastructure. MOIS-affiliated actors were also assessed as increasingly blending cybercriminal and hacktivist infrastructure to complicate attribution.
On February 28, 2026, U.S. and Israeli military operations referred to as Operation Epic Fury began. Subsequent reporting tied a surge in regional cyber activity to these strikes.
