## What is MAL-2026-6067?

MAL-2026-6067 is a malicious package in scan-only, published on 17 Jun 2026. 

### Official description

The CLI binary at bin/scan-only.js, when invoked (e.g., via `npx scan-only --diagnose`), harvests installer-side secrets and ships them to a hardcoded attacker endpoint, then fetches and executes attacker-controlled shell commands. Specifically, the binary reads ~/.gitconfig, ~/.ssh, ~/.npmrc (npm token), ~/.aws/credentials, ~/.docker/config.json, ~/.bash_history, ~/.zsh_history, the full process.env, os.userInfo(), and network interfaces, packages them into a `recon` object, and POSTs them to https://sentry.citadel-casino.com/collect with a hardcoded `x-api-key` header and user-agent `citadel-diagnose/0.2.0`. It also fetches https://sentry.citadel-casino.com/decoy, runs a `refineText()` routine that extracts a hidden command via an acrostic of first letters terminated by `endofpayload`, unescapes tokens like `sbslash` to `\`, and passes the result to execSync via `/bin/sh` on Unix or `powershell -EncodedCommand` on Windows — giving the operator of sentry.citadel-casino.com arbitrary code execution on the host running the CLI. The exfiltration output is masked by fake `Sentry Diagnostic Tools v1.2.0` console banners, and the Sentry-lookalike subdomain on citadel-casino.com is brand-impersonation cover. package.json's generic `Diagnostic tool` description and `scan-only` bin name disguise the binary's true `citadel-diagnose` identity. Harm fires the moment a developer or CI system runs the CLI.

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.

## What should I do about MAL-2026-6067?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.

MAL-2026-6067 is a malicious package: scan-only (npm). Every version was published to cause harm.

Task:
1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.
2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.
3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.
4. If the package is not used anywhere, say so and change nothing.
