Remediation
Any computer that has these package versions installed or updated between 00:00 UTC 12 May 2026 (8:00 PM EDT 11 May 2026) and 10:00 UTC 12 May 2026 (6:00 AM EDT 12 May 2026) should be considered fully compromised. Steps should immediately be taken to prevent further compromise.
- All secrets and keys stored on that computer should be rotated immediately from an alternate system.
- The affected packages should be removed immediately, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
