CHINA-LINKED HACKERS EXPLOITED LANSCOPE FLAW AS A ZERO-DAY IN ATTACKS

Summary from the TLDR InfoSec newsletter

Chinese cyber-espionage group Bronze Butler (Tick) exploited CVE-2025-61932, a critical request origin verification flaw in Motex Lanscope Endpoint Manager versions 9.4.7.2 and earlier, as a zero-day vulnerability for several months before it was patched in October. The attackers exploited this vulnerability to achieve unauthenticated remote code execution with SYSTEM privileges, deploying an updated Gokcpdoor malware variant that features multiplexed command-and-control communication and DLL sideloading for evasion, along with tools such as goddi Active Directory dumper and 7-Zip for data exfiltration to cloud storage services. Organizations using Lanscope Endpoint Manager must immediately upgrade to patched versions, as no workarounds exist, while security teams should monitor for indicators of Bronze Butler activity, including Gokcpdoor malware, OAED Loader, and connections to ports 38000/38002.
