🛡️ MAL-2026-11060 — f0-form-manipulator

Malicious code in f0-form-manipulator (npm)

Source: amazon-inspector

On npm install, the package's preinstall hook executes index.js, which collects host identifiers (os.hostname, os.platform, os.arch, os.homedir, dns.getServers) and POSTs them as JSON to a hardcoded Burp Collaborator subdomain at v62io3r4g3itdnqjg9h9pnh2mtslge43.oastify.com/hit. The exfiltration fires automatically without user interaction and reveals internal hostnames, platform details, and DNS configuration of any machine that installs the package. Behavior and naming are consistent with a dependency-confusion callback beacon.

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.
