MAL-2026-11153 Malicious code in triage_bot_using_sdkv3 (npm)

package.json registers a preinstall hook that runs index.js on npm install. index.js collects os.hostname(), os.userInfo(), home directory, DNS server configuration, and reads /etc/passwd and /etc/hosts via fs.readFileSync, then HTTPS-POSTs the payload to the hardcoded Burp Collaborator subdomain mh7rhchf58lgymyr9wffhwfprgx7lx9m.oastify.com. Installing the package on a default npm install causes installer host identifiers and local account/host files to be transmitted to an out-of-band attacker-controlled endpoint.

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.
