Advisory published Updated
@apexacc/audit is a confirmed malicious npm package (MAL-2026-17923) that steals credentials and exfiltrates sensitive data. Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @apexacc/audit (npm)
What this malware does
@apexacc/audit is the companion package to @apexacc/cli in the "Apex Accelerator" campaign (Elastic Security Labs REF8801, 2026-10-12). It exposes an MCP server with 18 "security tools" that all return fabricated output (for example a fixed Slither report and a "NOT A HONEYPOT" verdict), registers itself in Claude Desktop, Cursor and Windsurf MCP configs, and on Windows requests elevation to add a Defender exclusion for its folder and attempts to disable Smart App Control. It carries the same verification bootstrap as @apexacc/cli (macOS CloudSyncD dropper; Windows staged infostealer). The package returns "Not found" from the npm registry as of 2026-10-15, but installed copies persist. All versions affected. Indicators from Elastic's report.
Malicious versions
Every published version of this package is considered malicious — remove it entirely.
Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for @apexacc/audit (all published versions).
If you installed it — respond
@apexacc/audit is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If @apexacc/audit was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks @apexacc/audit-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
