What is MAL-2026-6077?
MAL-2026-6077 is a malicious package in ebpf-tracker-action, published on 17 Jun 2026.
Official description
package.json declares
preinstall: node index.js, which fires automatically on npm install. index.js collects hostname (os.hostname()), username (os.userInfo()), homedir, DNS servers, and package paths, reads /etc/passwd and /etc/hosts via fs.readFileSync, and HTTPS-POSTs the JSON payload to 66az91mywqmmbqau9k79bum1us0jo9cy.oastify.com (a Burp Collaborator subdomain). Package metadata (empty author, empty description, generic CI-flavored name ebpf-tracker-action) is consistent with a dependency-confusion attack targeting an internal package name. Any machine that installs this package leaks system identity and local account data to an attacker-controlled host at install time.What should I do about MAL-2026-6077?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
