Incident Summary
A security breach involving a trojanized version of SumatraPDF was reported to target Chinese-speaking individuals.

Affected parties are individuals who installed the trojanized PDF software and any environments where VS Code tunnel access was exposed. Limited public details are available about the scope, impact, and remediation status.
