Threats Tagged 't1560'

Security researchers have uncovered a sophisticated cyber espionage operation deploying two previously undocumented malware families, OctLurk and SilkLurk, targeting government and public-sector organizations across Central Asia and the Middle East. Both modular backdoors utilize victim-specific decryption mechanisms, extensive obfuscation, and in-memory execution to evade detection. The malware enables credential theft, remote access, network reconnaissance, and plugin-based expansion. Operations began in January 2025, affecting entities in Afghanistan, Kazakhstan, Kyrgyzstan, Syria, Tajikistan, and Uzbekistan. Victims include government offices, foreign affairs ministries, law enforcement agencies, healthcare providers, logistics organizations, research institutions, urban planning facilities, and educational establishments. Attackers deployed additional tools including Impacket's SecretsDump, Browser Password Decryptor, Pandora RC, Fscan, WinRAR, 7-Zip, and PlugX. A companion utility, LurkProxy, proxies a

Two newly identified backdoors, OctLurk and SilkLurk, have been targeting government organizations across Central Asia since January 2025. Victims span Afghanistan, Kyrgyzstan, Tajikistan, Uzbekistan, Kazakhstan, and Syria, affecting healthcare, research, government offices, ministries of foreign affairs, logistics, law enforcement, urban planning, and educational institutions. Both backdoors employ heavily obfuscated loaders customized per victim, using machine-specific data for decryption. They deploy multiple plugins for command execution, file manipulation, credential harvesting, keylogging, network scanning, and remote access. The attackers also utilized LurkProxy for network traffic proxying and deployed additional tools including PlugX, Impacket, FSCAN, and Pandora FMS agents. Analysis indicates both backdoors are operated by the same Chinese-speaking threat actor, though attribution to a specific known group remains unconfirmed. The campaigns demonstrate sophisticated persistence mechanisms and ext...

Two npm beta releases in the @joyfill namespace were compromised with an import-time JavaScript implant that uses blockchain transactions on Tron, Aptos, and BNB Smart Chain to retrieve encrypted payloads. The malicious code leads to a 77 KB Node.js remote-access trojan identified as DEV#POPPER, which establishes Socket.IO connections for remote control and can execute commands, upload files, read clipboard data, and persist through developer tools. A parallel execution branch downloads additional payloads including an 82 KB Python infostealer assessed to be OmniStealer, targeting browser credentials, Git configurations, and wallet extensions. The compromise affected @joyfill/layouts version 0.1.2-2773.beta.0 and @joyfill/components version 4.0.0-rc24-2773-beta.4, with approximately 16,000 weekly downloads. The loader exhibits exact code overlap with the PolinRider family and DEV#POPPER operations.
