MAL-2026-12872

Summary: Malicious code in bnpl-blocks-atom-bnpl-dropdown (npm)

Details: Source: amazon-inspector (fe2cdda88c39101955d7333e81f68b9cefe2dbfab23862351194168e2c61e5e9) index.js unconditionally requires./_support at package load. _support.js reconstructs a list of Cloudflare Workers hostnames (oob-worker.cf103-070.workers.de, oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev) and DNS discovery domains (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru) from split string literals joined at runtime, fetches an opaque binary via https.get, writes it to /tmp under cover-story names such as.cache_<rand> and dotnet_diag_<rand>.exe, chmods it 0755, and spawns it detached via /bin/sh -c or cmd. Platform-branched dispatch covers Linux, macOS, and Windows. A sibling lib/telemetry.js also concatenates the module name 'child_process' to evade static scanners. Environment-variable opt-outs (DISABLE_TELEMETRY, DO_NOT_TRACK) and a /tmp/.analytics_state freshness marker serve as cover for the dropper. Requiring or installing the package results in full-host code execution from unpinned, unverified, obfuscated attacker-controlled infrastructure. Source: ghsa-malware (b42d82e07577f5c12abd78af481dff80c471c910111551b755368719ab753396) 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.
