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.

First, it POSTs a JSON platform snapshot to the hardcoded bare-IP endpoint http://193.70.34.101:20099/vote, with the host string reconstructed at runtime by joining ['193','70','34','101'] to evade static hostname matching. Second, it XOR-decodes (key 'stf2026') an embedded byte array (ADDON_ENC) into a URL pointing at a GitHub releases/download/.../main.exe under an attacker-controlled account, fetches the payload into %TEMP%\\main.exe, and spawns it detached with stdio:'ignore' and windowsHide:true. On WSL/virtualized Linux it XOR-decodes a PowerShell bridge command and script (BRIDGE_LAUNCHER_ENC, BRIDGE_SCRIPT_PRE_ENC, BRIDGE_SCRIPT_POST_ENC) to invoke the same payload on the Windows host. The fetched binary has no pinning, no hash or signature verification, and the package name uses a cover story ('addon', 'TELEMETRY.addon') while shipping no native source consistent with a real addon (index.js exports {}). Package has no legitimate purpose beyond delivering the dropper.","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 raectjs (npm)","id":"MAL-2026-14187","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":[],"last_affected":[],"package":"raectjs","purl":"pkg:npm/raectjs","source":"MAL-2026-14187"}],"products":null,"published":"2026-08-18","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-2026-14187/"}
