  • The vulnerability is a Type Confusion in V8 (Chrome's JavaScript engine). Flag Chrome versions prior to 116.0.5845.179 as unpatched and at risk; prioritize patching endpoints still running those versions.
  • ·One-time links were also used as an alternative delivery vector alongside MITM injection; link-based delivery may not produce the same network-level redirect pattern, reducing detectability via proxy/DNS monitoring alone.
