A newly identified threat group, designated as GhostShell, has been conducting cyber operations against Ukraine's unmanned aerial vehicle supply chain since February 2026. The attackers employ malicious archives containing decoy documents that impersonate Besomar, a Ukrainian manufacturer of high-precision interceptor drones, to compromise defense and procurement networks. The attack chain deploys three distinct payloads: a custom backdoor (122.exe) utilizing mTLS client certificates for screen capture and command execution, an in-memory stager (update.exe) disguised as a Windows Health Service that fetches next-stage payloads via Telegram, and a proxy launcher (22.exe) that tunnels traffic through Xray Core to deploy the Vidar v2 information stealer. The targeting strongly suggests a Russian cyber operation, though analysts employ the SOLBIT framework to avoid attribution based on easily forgeable indicators.

UNC1549, an Iranian-linked threat group, has been targeting aerospace, aviation, and defense industries since mid-2024. They employ sophisticated initial access techniques, including exploiting third-party relationships and targeted phishing. The group uses custom malware like TWOSTROKE, LIGHTRAIL, and DEEPROOT for persistence, and tools like DCSYNCER.SLICK and CRASHPAD for privilege escalation. UNC1549 demonstrates advanced lateral movement, reconnaissance, and defense evasion tactics. They extensively use SSH reverse tunnels and Azure infrastructure for command and control. The group's primary objective appears to be espionage, focusing on data collection and leveraging compromised organizations to target others in the same sector.

The Lazarus Group, a DPRK-linked threat actor, has launched a targeted espionage campaign against aerospace and defense sectors using a new variant of the Comebacker backdoor. The attack employs spear phishing with highly specific lure documents to deliver macro-based malware. The infection chain is multi-staged, featuring custom decryption algorithms and encrypted command-and-control communications, indicating advanced evasion techniques. The campaign infrastructure remains active, suggesting ongoing operations. This threat poses risks to confidentiality and integrity of sensitive defense-related information. European aerospace and defense organizations should enhance phishing defenses and monitor for indicators such as specific file hashes and suspicious domains. No CVSS score is assigned, but the threat is assessed as high severity due to its targeted nature, potential impact, and sophisticated malware. Countries with significant aerospace and defense industries and geopolitical interest in DPRK activities are most at risk. Immediate mitigation includes user training, macro restrictions, network monitoring, and threat intelligence sharing.

RedNovember, a Chinese state-sponsored threat group, has expanded its cyber-espionage activities globally. The group targets high-profile government, intergovernmental, and private sector organizations, focusing on defense, aerospace, and technology sectors. It uses the Go-based backdoor Pantegana and Cobalt Strike for intrusions, exploiting vulnerabilities in perimeter appliances. RedNovember's tactics include combining weaponized proof-of-concept exploits with open-source tools, allowing for scalable operations and attribution obfuscation. The group has shown particular interest in targets across the US, Taiwan, South Korea, and Panama, often aligning its activities with geopolitical events and Chinese strategic interests.

A sophisticated phishing campaign, likely attributed to Pakistan-linked APT36 (Transparent Tribe), is targeting Indian defense organizations and government entities using spoofed domains. The attackers employ advanced social engineering techniques, including real-time OTP harvesting, to bypass multi-factor authentication and gain access to official email accounts. The campaign uses typo-squatted domains mimicking government platforms to steal credentials. Infrastructure analysis reveals connections to Pakistani IPs and possible staging via Zah Computers. The threat actors create a false sense of legitimacy by referencing trusted authorities and secure communication flows. This coordinated approach highlights the severity of the threat and the attackers' strategic intent, potentially posing significant risks to national security.

UNG0901, a threat group targeting Russian aerospace and defense sectors, has been discovered conducting a spear-phishing campaign against the Voronezh Aircraft Production Association. The operation, dubbed 'CargoTalon', utilizes a custom DLL implant called EAGLET, which is disguised as a ZIP file containing transport documents. The infection chain involves a malicious LNK file that executes the EAGLET implant, which then establishes communication with a command-and-control server for remote access and data exfiltration. The campaign employs sophisticated tactics, including decoy documents related to Russian logistics operations, and shows similarities with another threat group known as Head Mare. The attackers' motivation appears to be espionage against Russian governmental and non-governmental entities.

This analysis explores the infrastructure of APT36, also known as Transparent Tribe, using passive DNS and host response history. Starting with indicators from a CyberXTron report on a targeted phishing attack against Indian Government and Defense, the investigation expands through DNS history, IP pivoting, and host response analysis. Key findings include shared name server patterns, non-Cloudflare IP addresses, and connections to previously unreported domains. The research identifies potential new infrastructure using ETag pivoting, revealing domains with similar subdomain conventions to known Transparent Tribe assets. The methodology demonstrates the power of comprehensive DNS data and host response history in uncovering hidden connections and potential threat infrastructure.
