ESET researchers discovered two undocumented Windows variants of the SprySOCKS backdoor, WINDRV and WINPLUS, attributed to the China-aligned FishMonger APT. These variants utilize advanced stealth techniques, including a custom kernel driver for hiding artifacts and diverting TCP traffic, as well as print processor abuse for persistence.
SHADOW-EARTH-053 is a China-aligned cyberespionage campaign exploiting legacy N-day vulnerabilities in Microsoft Exchange and IIS servers to target government and defense sectors primarily in Asia. The threat actors utilize GODZILLA web shells for persistence and deploy ShadowPad implants via DLL sideloading, sharing significant operational overlaps with another intrusion set tracked as SHADOW-EARTH-054.
Check Point Research discovered a zero-day vulnerability (CVE-2026-3502) in the TrueConf client update mechanism, exploited in 'Operation TrueChaos' against Southeast Asian governments. Attackers compromised on-premises TrueConf servers to distribute malicious updates, utilizing DLL sideloading and UAC bypass techniques to deploy the Havoc C2 framework.
