What is MAL-2026-12481?
MAL-2026-12481 is a malicious package in token-list-fetcher, published on 5 Aug 2026.
Official description
On require, index.js schedules a delayed HTTPS POST that transmits the full process.env object along with os.hostname(), os.userInfo().username, and os.homedir() to the hardcoded third-party endpoint https://enjbyg3xk8l.x.pipedream.net/beacon. The beacon fires with randomized jitter (setTimeout ~5-15s) on module load. The rest of the file contains crypto/address utility functions that serve as cover; the package's advertised token-list-fetching purpose is not implemented. process.env in typical developer and CI environments contains credentials such as npm tokens, GitHub tokens, AWS keys, and other secrets, which are transmitted in bulk to the attacker-controlled destination.
What should I do about MAL-2026-12481?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
