What is MAL-2026-15627?
MAL-2026-15627 is a malicious package in hyperliquid-composer, published on 31 Aug 2026.
Official description
bin/cli.js (also declared as the package main) collects the installer's username via whoami / os.userInfo(), plus os.hostname() and platform, and POSTs them to the hardcoded Cloudflare Workers endpoint https://oobme.kunalsharma0553.workers.dev/r/7bq6fz3l15r9. The exfiltration fires on require() of the module or on CLI invocation, with no user consent or configuration. The package name resembles legitimate Hyperliquid tooling.
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-2026-15627?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
