{"id":"MAL-2026-13662","summary":"Malicious code in sme-rko-finance-front-payments-feed-display-list (npm)","details":"\n---\n_-= Per source details. Do not edit below this line.=-_\n\n## Source: amazon-inspector (eedf1850bd0f58b8adef8a6b6c3ac13adf7848819306e5a7b9518cbb174911a3)\nOn require of the package's main module, _compat.js unconditionally downloads a platform-specific executable and runs it. Destination hosts are assembled at runtime from split string arrays (e.g. ['oob-','worker.cf99-9b3.wo','rkers.de','v'].join('')) to evade static analysis, resolving to anonymous *.workers.dev subdomains that do not match any package publisher. The fetched bytes are written to a temp path under decoy names (dotnet_diag_*.exe,.cache_*), chmodded 0755, and spawned detached via child_process.spawn ('/bin/sh' or 'cmd'), with a platform map covering linux/darwin/win32. When HTTP fetch fails, a fallback channel resolves DNS TXT records at c.\u003cdomain\u003e under *.dl.wel1.ru for a chunk count, reassembles base64-encoded payload chunks from 0.\u003cdomain\u003e, 1.\u003cdomain\u003e,..., and executes the resulting binary. No hash or signature verification is performed. The package name presents as a benign finance-frontend UI component, which is inconsistent with the download-and-execute behavior.\n","modified":"2026-08-08T01:04:55.490148323Z","published":"2026-08-08T00:45:22Z","database_specific":{"malicious-packages-origins":[{"modified_time":"2026-08-08T00:45:22Z","sha256":"eedf1850bd0f58b8adef8a6b6c3ac13adf7848819306e5a7b9518cbb174911a3","source":"amazon-inspector","versions":["35.8.1"],"id":"IN-MAL-2026-017152","import_time":"2026-08-08T00:53:07.19014393Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/sme-rko-finance-front-payments-feed-display-list/v/35.8.1"}],"affected":[{"package":{"name":"sme-rko-finance-front-payments-feed-display-list","ecosystem":"npm","purl":"pkg:npm/sme-rko-finance-front-payments-feed-display-list"},"versions":["35.8.1"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/sme-rko-finance-front-payments-feed-display-list/MAL-2026-13662.json","cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"sha256":"b9bdf00151502f5e7d07694d8562eb6ad93d23416ca7b4c3d69ca5d561df6873","tlsh":"84a1b65a06fa70180792e5d4892f5417719afa5332c4ecc0fb0c66984fda128c3b39fd","path":"_compat.js"}],"package_integrity":[{"filename":"sme-rko-finance-front-payments-feed-display-list-35.8.1.tgz","hashes":{"sha1":"608e4bffcdc06956e56f42d834095731df2edc00","sha512_sri":"sha512-b3ZdFWXIM/9xSuo9b7wE4iYmVxWhVAs3F1MT0s5dfdqPnEzybIjE/Yz05ApBU68XbY9Hdwx3gbFw5mP+NV/gXA=="}}]}}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
