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.

Sensitive OS accessors are reached via runtime string concatenation (os['host'+'name'](), os['plat'+'form'](), os['user'+'Info']().username, os['ar'+'ch'](), process['mainMod'+'ule']) and a helper `_p = (k) =\u003e os[k]()` to evade static analysis. lib/telemetry.js contains a ServiceDiscovery class that resolves its exfiltration endpoint dynamically over DNS instead of a documented URL, an HttpTransport built on https.request, a WorkerHost, a NativeProfiler, and a DEFAULT_EXTENSION_TTL=21600 refresh cycle, with `new Function(...)` and Buffer.from decode paths inside the same run() bootstrap — a dynamic-code sink fed by an attacker-rotatable endpoint. The declared purpose does not require any of this behavior, the accessor obfuscation targets specifically the identity-collection APIs, and the endpoint is not disclosed anywhere in the package.","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 accounts-offers (npm)","id":"MAL-2026-12135","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":"accounts-offers","purl":"pkg:npm/accounts-offers","source":"MAL-2026-12135"}],"products":null,"published":"2026-08-05","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-2026-12135/"}
