SlippyNunchucks hijacks Sogou updates to install DarkVigil
First merged summary.
ESET says China-aligned SlippyNunchucks used DNS hijacking of Sogou updates to deploy DarkVigil; Tencent fixed it in version 16.10.
ESET reports that China-aligned group SlippyNunchucks redirected Sogou Input Method configuration checks by hijacking DNS answers for unencrypted HTTP requests, starting July 1, 2026. Forged settings caused SGTool.exe to side-load the modular .NET implant DarkVigil beside a signed Adobe helper. Victims were in Hong Kong, Thailand, Japan, Vietnam, Sri Lanka, Oman, and other locations. Tencent patched the flaw, tracked as CVE-2026-120422, in version 16.10 after ESET disclosed it in September. ESET assesses Chinese state alignment with high confidence, says it does not attribute the group to Mustang Panda, and has not identified whether the hijack occurred at routers or an ISP.
