OpenSSF Malicious Packages via OSV

Summary

Malicious code in @nimbusedge2/xa (npm)

Details

package.json declares a preinstall lifecycle script that runs an interactive bash reverse shell to the hardcoded host 147.93.157.202.nip.io on TCP port 8080 and pipes the shell's output through curl to http://canarytokens.com/terms/7dc94zmd3so67n5vbz5bxmt7v/contact.php. Because preinstall fires automatically on `npm install`, any machine that installs this package attempts to grant a remote party interactive command execution on the installer's host and unconditionally beacons install-time output over plain HTTP to a third-party tracking endpoint. The nip.io wrapper resolves the bare IP 147.93.157.202 without DNS registration, and the destination and token are hardcoded in the manifest with no caller configuration path.

Decision reason

OpenSSF Malicious Packages via OSV confirms @nimbusedge2/xa@1.1.0 as malicious (MAL-2026-16306): Malicious code in @nimbusedge2/xa (npm)
