Iranian Hackers Target Electronics Maker in Global Espionage Push

Iran-linked hackers, known as MuddyWater, infiltrated a major South Korean electronics manufacturer's network for a week in February 2026, as part of a massive global cyber-espionage campaign targeting nine high-profile organizations across multiple sectors and countries.

Iran-Linked Hackers Breached Korean Electronics Maker in Global Spying Campaign

Iranian state-sponsored threat group Seedworm conducted a widespread espionage campaign in early 2026, compromising at least nine organizations across nine countries on four continents. Victims included a major South Korean electronics manufacturer, government agencies, an international airport in the Middle East, Southeast Asian industrial manufacturers, a Latin American financial services provider, and educational institutions. The attackers utilized DLL sideloading techniques with legitimately signed Fortemedia and SentinelOne binaries to execute malicious payloads, deployed Node.js-based implants for orchestration, and employed multiple PowerShell scripts for reconnaissance, credential theft, and privilege escalation. Data exfiltration was conducted through public file-transfer service sendit.sh to blend malicious traffic with legitimate cloud services. The campaign demonstrates Seedworm's evolved tradecraft and expanded targeting beyond traditional Middle Eastern focus areas.

Iranian APT Seedworm Targets Global Organizations via Microsoft Teams

In late February 2026, following escalating Middle East tensions and coordinated military actions, Iranian APT group Seedworm launched sophisticated social engineering attacks via Microsoft Teams. Attackers impersonated IT support personnel using deceptive Microsoft 365 tenant domains to convince victims to execute malicious MSI installers. The campaign deployed a custom backdoor called Dindoor, which leveraged legitimate Deno runtime to execute obfuscated payloads in-memory, minimizing detection. The operation included multiple components for persistence, command-and-control communications, and data exfiltration. Infrastructure overlapped with previously reported MuddyWater operations. The attack demonstrates the group's evolution in using collaboration platforms as initial access vectors while combining dual-use tooling with living-off-the-land techniques to bypass traditional security controls.
