The loader downloads and runs a platform-specific native payload from attacker-controlled Cloudflare Workers hosts, or reconstructs the payload from DNS TXT records under `well1.site` if HTTPS delivery fails. Systems that imported this package should be considered compromised; rotate accessible secrets and investigate temporary-file execution and DNS activity to the listed infrastructure.\n\n---\n_-= Per source details.

The fetched bytes are written to a temp path under a disguised name (dotnet_diag_*.exe /.cache_*), chmodded 0o755, and executed detached via spawn(\"/bin/sh\", [\"-c\", fp + \" &\"], {detached:true}).unref() on Unix or spawn(\"cmd\",...) on Windows. A companion module lib/telemetry.js (not currently wired into the require graph) contains a fuller variant of the same fetch/decode/spawn logic behind a Sentry-style \"analytics SDK\" cover story, using string concatenation to hide dangerous APIs (require(\"child_\" + \"process\"), fs[\"chmod\" + \"Sync\"]). Requiring or installing the package results in execution of attacker-controlled bytes on the installer's host.\n\n## Source: ghsa-malware (c1969a01e59493b2cf8424c931804e22aab7a4c57b8db734d86fbb7d1fe8bd59)\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.\n","affected":[{"package":{"name":"pfp-forms-sme-loan","ecosystem":"npm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["20.2.1"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"_bridge.js","sha256":"a7b851e62c96239dadd30e8162f4993f6571bde95d1137604d0b5be3ae419ecc","tlsh":"1da1ba961566701d87b0ebe487275419f65bf653378082d4fbac55d40fb602883b1efc"}],"package_integrity":[{"filename":"pfp-forms-sme-loan-20.2.1.tgz","hashes":{"sha1":"3f90ce17e49db24412a54ef709f67a6ce62d15dd","sha512_sri":"sha512-Wy40Mk2frPUKgUX1ngJaBFsJ6kBQf55bZmqT/LvJ85C8AYE+NMON6tih+0HuvUJglumfo3S/bB1mY+xCCfXwhg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/pfp-forms-sme-loan/v/20.2.1"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-p37j-6hr3-m2q3"}],"database_specific":{"iocs":{"domains":["oob-worker.cf100-416.workers.dev","oob-worker.cf101-adf.workers.dev","oob-worker.cf99-9b3.workers.dev","tin.dl.well1.site","tina.dl.well1.site","ldr.dl.well1.site","win.dl.well1.site"]},"malicious-packages-origins":[{"id":"IN-MAL-2026-014772","import_time":"2026-08-05T13:08:45.259995437Z","modified_time":"2026-08-05T12:49:00Z","sha256":"895bf0e3e06e148eff01868554fe9bfe615a4c611d07afa331acfcf23d094530","source":"amazon-inspector","versions":["20.2.1"]},{"id":"GHSA-p37j-6hr3-m2q3","import_time":"2026-08-20T17:25:01.631696984Z","modified_time":"2026-08-20T16:37:50Z","ranges":[{"events":[{"introduced":"0"}],"type":"SEMVER"}],"sha256":"c1969a01e59493b2cf8424c931804e22aab7a4c57b8db734d86fbb7d1fe8bd59","source":"ghsa-malware"}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"skb1209","type":"FINDER"}]}
