Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-2407/ (Markdown: https://insights.sbomify.com/MAL-2026-2407/index.md)","id":"MAL-2026-2407","markdown":"https://insights.sbomify.com/MAL-2026-2407/index.md","name":"MAL-2026-2407","record":{"aliases":["GHSA-3v4h-w4g3-h6r2"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Malicious package due to code obfuscation, dynamic module loading, process exposure, suspicious install script, and untrustworthy author email.\n\nThis 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 `research@sl4x0.xyz` (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.\n\nAny 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.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in @ceeferenderer/itg-renderer-sdk (npm)","id":"MAL-2026-2407","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":[],"package":"@ceeferenderer/itg-renderer-sdk","purl":"pkg:npm/%40ceeferenderer/itg-renderer-sdk","source":"MAL-2026-2407"}],"products":null,"published":"2026-03-24","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-2407/"}
