MAL-2026-18310 Malicious code in @regex33-hackerone/tb-compat (npm)

Package @regex33-hackerone/[email protected] contains two files with no detected malicious behavior. No install-time lifecycle scripts fetching remote content, no credential or environment scraping, no hardcoded exfiltration endpoints, no obfuscated payloads, and no silent-relay or backdoor patterns were identified in the scanned contents. The hackerone scope suggests the package may be associated with security research or a bug-bounty researcher's test artifact.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, 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.
