A fallback channel retrieves base64-encoded payload chunks over DNS TXT queries against sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru (c.\u003cdomain\u003e for chunk count, N.\u003cdomain\u003e for chunk data). The fetched bytes are written to /tmp or %TEMP% under disguised names such as.cache_\u003chex\u003e or dotnet_diag_\u003chex\u003e.exe, chmod 0755, and executed detached via spawn(\"/bin/sh\",[\"-c\", path+\" &\"],{detached:true}).unref() or spawn(\"cmd\",...) on Windows. No hash or signature verification is performed. Execution is gated only by an 'analytics_state' filesystem stamp and cover-story naming ('analytics', 'telemetry', 'dotnet_diag'). The package name impersonates a legitimate BNPL/payment integration while shipping a binary dropper.\n\n## Source: ghsa-malware (c0880c543b06fa184b4f5210c4dba55339f8c0bed3ab7ad2c2e7b6c51b0ff8c4)\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","aliases":["GHSA-cxvx-6rxg-4hf3"],"modified":"2026-08-06T01:20:47.714769379Z","published":"2026-08-05T15:27:08Z","database_specific":{"malicious-packages-origins":[{"import_time":"2026-08-05T16:13:34.159572276Z","modified_time":"2026-08-05T15:27:08Z","sha256":"f2f3a20016e1936bdca56ddd0208270b791b048a3d4c7cca682ff83462724bb2","source":"amazon-inspector","versions":["35.4.8"],"id":"IN-MAL-2026-015703"},{"source":"ghsa-malware","id":"GHSA-cxvx-6rxg-4hf3","import_time":"2026-08-06T00:58:53.358027365Z","modified_time":"2026-08-05T18:05:31Z","ranges":[{"events":[{"introduced":"0"}],"type":"SEMVER"}],"sha256":"c0880c543b06fa184b4f5210c4dba55339f8c0bed3ab7ad2c2e7b6c51b0ff8c4"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-boxy-atom-desktop-bnpl-dangerously-html/v/35.4.8"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-cxvx-6rxg-4hf3"}],"affected":[{"package":{"name":"dolyame-boxy-atom-desktop-bnpl-dangerously-html","ecosystem":"npm","purl":"pkg:npm/dolyame-boxy-atom-desktop-bnpl-dangerously-html"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["35.4.8"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-boxy-atom-desktop-bnpl-dangerously-html/MAL-2026-13294.json","indicators":{"evidence_files":[{"sha256":"a5eee619360cd11cfc188fc508507aed8f226c473fbb491a8903c0a0fb113413","tlsh":"08a1b6aa156670188b7097e1c71b5416f65bf6633380d284fb9ca5981fb212483b2efc","path":"_polyfill.js"}],"package_integrity":[{"filename":"dolyame-boxy-atom-desktop-bnpl-dangerously-html-35.4.8.tgz","hashes":{"sha1":"1dbf8c3365592de723b92eaf92574921e9817c60","sha512_sri":"sha512-Sd2g32lSlJKIXSj1BpzvGVNB/6wC9KTJ2oKqwWuzK1t5bCT74+CFVRLP1T7iCVCntbUjMRecBZ8a5dL8G75t+w=="}}]},"cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"},{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."}]}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
