What is MAL-2026-2407?
MAL-2026-2407 is a malicious package in @ceeferenderer/itg-renderer-sdk, published on 24 Mar 2026.
Official description
Malicious package due to code obfuscation, dynamic module loading, process exposure, suspicious install script, and untrustworthy author email.
This package performs silent reconnaissance against any machine that installs or requires it. The package.json declares scripts.install = node index.js, and index.js also loads lib/core.js at require() time. lib/core.js obtains the os and dns modules via module.constructor._load(...) — a deliberate bypass of simple require('os')/require('dns') source grep — then reads os.userInfo().username, os.hostname(), and path.basename(process.cwd()), concatenates them with a timestamp and the hard-coded domain oob.sl4x0.xyz, and calls dns.resolve4() on the resulting subdomain. Because oob.sl4x0.xyz is an attacker-controlled authoritative nameserver, the victim's resolver leaks the username, hostname, and working-directory name as DNS query labels. The sensitive identifiers and the domain itself are stored as hex byte arrays in lib/6ad264.js and lib/b02e30.js and reassembled at runtime via String.fromCharCode, and the JS filenames are random hex — clear evasion of static review. Supporting red flags: the author email is [email protected] (same attacker-owned domain), the version is 99.9.9, and the package description is generic. This is active exfiltration of installer-side data executed on both install and import, with no legitimate functionality documented.
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.
What should I do about MAL-2026-2407?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
