Google-owned Mandiant reported that state-sponsored threat actors are directly targeting employees at Defense Industrial Base (DIB) organizations, including contractors and suppliers tied to defense programs across Western countries. The activity is aimed at stealing sensitive information and gaining access to networks that support military, aerospace, and government supply chains, with attackers focusing on individuals as an entry point rather than only attacking perimeter systems.
Reporting on the findings said the campaigns involve cyber espionage operations against defense-sector personnel and contractors, underscoring the DIB as a high-value target for foreign intelligence collection. The activity highlights persistent efforts by nation-state operators to compromise trusted vendors and staff connected to defense ecosystems, raising concerns that employee-focused intrusions could expose proprietary defense data, operational plans, and broader supply-chain relationships.

Google’s Threat Intelligence Group (GTIG) reported sustained and expanding cyber operations against the **defense industrial base (DIB)** by state-linked and aligned actors from **China, Iran, North Korea, and Russia**, driven by battlefield technology demands and geopolitical conflict. Reported themes include targeting defense organizations supporting the Russia–Ukraine war, **social engineering and recruitment/hiring-process abuse** aimed at employees (notably attributed to North Korean and Iranian activity), increased reliance on **edge devices and appliances** for initial access by China-nexus groups, and heightened **supply-chain exposure** tied to compromises in adjacent manufacturing ecosystems. The reporting highlights specific tactics and actor activity, including Russia-linked **APT44 (Sandworm)** efforts to access data from **Telegram and Signal**, including use of a Windows batch script (`WAVESIGN`) to decrypt and exfiltrate data from Signal Desktop after likely obtaining physical access to devices in Ukraine. Additional activity described includes Ukraine-focused campaigns using defense-themed lures (e.g., drones and counter-drone systems) and broader nation-state use of **zero-day exploitation in edge devices** to establish footholds in defense contractors’ networks, reinforcing GTIG’s assessment that “pre-positioning” and continuous access-building are now baseline expectations for DIB organizations.

Google Threat Intelligence Group (GTIG) reported that the **defense industrial base (DIB)** is under sustained, multi-vector pressure from state-backed and aligned actors seeking to steal sensitive military technology, disrupt supply chains, and undermine national security. The report highlights Russian-linked activity focused on **unmanned aircraft systems (UAS)** and other emerging technologies, including **TEMP.Vermin** using drone-themed lures to deliver malware and **APT44 (Sandworm/GRU)** targeting military personnel devices with tooling such as **INFAMOUSCHISEL** to harvest data from battlefield-related applications; it also notes some Russian operators are using **LLMs** to improve reconnaissance and social-engineering effectiveness. GTIG also describes North Korea’s continued use of **IT-worker/insider** placement to generate revenue and access within Western organizations. Separately, reporting on **Transparent Tribe (APT36)** describes ongoing espionage campaigns against Indian government and defense targets across Windows and Linux, including spear-phishing that deploys **Geta RAT** and execution chains abusing legitimate Windows components (e.g., `mshta.exe`) and **XAML deserialization** for evasion, alongside a shift toward more mature Linux tooling and persistence. A third report (Picus Labs’ *Red Report*) is broader trend research rather than a specific incident, claiming ransomware encryption is declining while “**sleeperware**”/dormant extortion tradecraft is rising based on ATT&CK technique prevalence across large-scale simulation and telemetry; it does not materially add to the defense-sector espionage narrative beyond general attacker TTP trends.

Google’s Threat Intelligence Group reported an intensifying, state-backed cyber-espionage campaign against **Western defense companies**—particularly across Europe—describing a “constant, multi-vector siege” aimed at stealing sensitive R&D, disrupting production, and gaining insight into next-generation battlefield systems. The report highlights **drone manufacturers and advanced weapons developers** as priority targets, with **Russia-linked activity** emphasized in the context of the war in Ukraine and a focus on unmanned aircraft technologies and their suppliers. Google attributed one phishing campaign to **UNC5976**, which used **malicious Remote Desktop Protocol (RDP) files** and **spoofed domains** impersonating defense firms across multiple countries. Google assessed that multiple state actors—**Russia, Iran, China, and North Korea**—are leveraging a broad set of access paths, including exploitation of **hiring processes**, **personal accounts**, and **remote work** environments, while smaller manufacturers and adjacent suppliers are also seeing **extortion attempts**, indicating widening supply-chain pressure. Separate reporting also described leaked documents indicating China has used a training platform (*Expedition Cloud*, developed by CyberPeace) to rehearse critical-infrastructure intrusions against neighboring countries by building network “templates” of targets and running reconnaissance-to-attack drills, underscoring the operational maturity and preparation that can translate into real-world campaigns against high-value sectors such as defense and critical infrastructure.
