In Q3 2026, attackers targeted Windows-based MS-SQL and MySQL database servers using brute-force, dictionary attacks, and vulnerability exploitation. They deployed cryptocurrency miners (XMRig), backdoors (GotoHTTP), SoftEther VPN infrastructure, and various web shells for persistence. Additional tools included VShell for remote command execution, HackBrowserData for credential theft, Fscan for reconnaissance, and Cloudflared for port exposure. Attackers created backdoor RDP accounts and used SoftEther VPN servers as command and control infrastructure. The attacks mainly exploited weak passwords, poor account management, and insufficient security on exposed database servers.
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...
Malware campaigns exploiting vulnerabilities in Ivanti Connect Secure devices, specifically CVE-2025-0282, have been active from December 2024 through July 2025. Attackers use MDifyLoader to side-load Cobalt Strike Beacon DLLs, along with vshell RAT and Fscan network scanner, to maintain persistent access. Initial access is gained via brute-force attacks, direct exploitation, and stolen credentials. The threat actors employ advanced lateral movement, persistence mechanisms such as domain account creation and malware service/task registration, and evasion techniques including use of legitimate files and ETW bypasses. European organizations using Ivanti Connect Secure devices are particularly targeted. The threat is assessed as medium severity due to moderate impact and exploitation complexity. No public exploits are currently available.
