Official description
Package name impersonates the Exodus cryptocurrency wallet brand. package.json declares
"postinstall": "node src/canary.js", and src/canary.js performs a DNS lookup and HTTPS GET to a hardcoded Serveo reverse-tunnel host (96e03fa6c292469a-172-245-86-254.serveousercontent.com/c) on every npm install. Serveo (serveousercontent.com) is a reverse-SSH tunneling service frequently used to expose non-publisher hosts; this is not Exodus infrastructure. The callout leaks the installer's IP address and timing to the tunnel operator and demonstrates arbitrary install-time code execution on the installer's machine. Although the package self-describes as a HackerOne PoC canary, the technique is a live supply-chain attack pattern operating against any machine that installs it.What should I do about MAL-2026-5443?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
