A DNS-TXT-record fallback channel retrieves chunked base64 payloads from numbered subdomains of dl.wel1.ru when HTTPS delivery fails. A cooldown stamp file suppresses repeat execution and environment-variable checks gate execution to evade sandboxes. The package is advertised as a UI toolkit and has no legitimate need for a platform-native binary, obfuscated hostname assembly, or a DNS covert channel. Installing or importing this package causes remote code execution on the host.\n","affected":[{"package":{"ecosystem":"npm","name":"dolyame-ui-codemods"},"versions":["35.2.6"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"_polyfill.js","sha256":"711d749650d6b347a73d2ad914855bc8104bfbc1d81fcb3f7fdd444d8a83bd61","tlsh":"32a1b75a166a710887b09be0c7174416f55ff2633381c295fb5ca5981fb612483b2efc"}],"package_integrity":[{"filename":"dolyame-ui-codemods-35.2.6.tgz","hashes":{"sha1":"f0a473a43096fb542576a8ef6b73d1e8b5defaa1","sha512_sri":"sha512-uzgf/Sy2MFCszLvyOjj7Lx1AqhNUO5sbFaC6bgt22z71pxUCjHoiCQGVkp8R9XdMeS20r9GiPqlZL3ZZTG5OTQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-codemods/v/35.2.6"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015636","import_time":"2026-08-05T15:20:01.138672519Z","modified_time":"2026-08-05T15:16:54Z","sha256":"aa4592f76ef0995b4e3c8b0cc15c00862cf594cbaebbfcd2bf25d2640bbf6012","source":"amazon-inspector","versions":["35.2.6"]}]}}
