Uncertainty and limitations
Read the evidence limits before acting on this record.
The record reflects Socket analysis published July 14, 2026. HOL has not independently attributed the actor or measured the full installed victim population.
- Public campaign details intentionally omit live infrastructure and executable payload material.
Guard coverage and policy
What Guard's reviewed assertions do and do not claim for this campaign, and the reviewed starting points for defense.
Not covered, or partially covered
partial
Guard can apply package-install policy on eligible observed actions, but it does not replace registry intelligence or endpoint response after a malicious package has executed.
- Recipe available
Require review or explicit approval for new or changed dependency installation before an eligible package-manager action executes.
Coverage depends on the active Guard release, package manager, harness event surface, and local policy. It is not a guarantee that every dependency path is intercepted.
Safe next step. Campaign guidance is defensive context. It does not auto-apply policy or claim universal campaign coverage.
