OpenSSF/OSV advisory MAL-2026-10979 confirms this npm version as malicious.

Advisory

MAL-2026-10979

Source

OpenSSF Malicious Packages via OSV

Summary

Malicious code in @apexfdn/apex (npm)

Details

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.

Independent LPM AI assessment

Suspicious

Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree.

The package is an unverified remote-binary carrier activated during installation, which is a real unresolved supply-chain risk. Source inspection does not establish malicious behavior of the absent payload.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

npm postinstall; later invocation of `apex`

Impact

A release or redirect compromise can supply code executed by the installed CLI.

Mechanism

unauthenticated remote binary staging and CLI execution

AI rationale

Independent scan evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for AI warning decision

package.json runs `node install.cjs` in postinstall.
install.cjs downloads platform executables from github.com/Apex-Foundation/copilot.
install.cjs follows redirects and performs no checksum or signature validation.
install.cjs downloads a Windows native addon to ~/.apex/natives.
apex.cjs executes the downloaded bin/apex with inherited environment.

Evidence against

Installer source contains no credential harvesting or exfiltration.
No agent-config mutation or destructive filesystem action is present.
Downloaded binary is not bundled, so its behavior cannot be established by source inspection.
