The bytes are written to /tmp or the Windows temp directory under randomized names such as.cache_XX or dotnet_diag_XX.exe, made executable via fs[\"chmod\"+\"Sync\"](path, 0o755), and launched detached with cp.spawn(\"/bin/sh\", [\"-c\", filePath+\" &\"], {detached:true}).unref(). A time-gated flag in /tmp suppresses re-run within roughly six hours. If HTTPS delivery fails, _compat.js falls back to dns.resolveTxt against sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru: it reads a counter TXT record at c.<domain>, then batches queries for numbered subdomains, concatenates the TXT contents, and base64-decodes the result into the executable payload. lib/telemetry.js contains a parallel fetch->write->chmod 755->spawn path camouflaged as a Sentry-lookalike \"apm.node\" SDK. child_process, chmodSync, and hostname API names are split-string obfuscated to evade static scanners. The package name mimics a Russian BNPL brand while its actual behavior is retrieving and executing attacker-controlled native code on every import.\n","affected":[{"package":{"ecosystem":"npm","name":"dolyame-ui-tabsblock"},"versions":["35.8.1"],"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":"_compat.js","sha256":"b3670687712a51071f4e297bbc9d442f4757726a35c3c468a71608a92aca879c","tlsh":"7da1c95a1afa701803a2e1d8842f5416b1afe69332c5d5d4fb4c66984f9717883b39fc"},{"path":"lib/telemetry.js","sha256":"ad7bc7409cfc1af69d802a69c30d92034b4c5b7180eabd2ea39dc0bfd3e8a670","tlsh":"0b733f4966fb10214263b0685fbb40437635c4072a4aed5dba9c43ec9f8db3896f1fb9"}],"package_integrity":[{"filename":"dolyame-ui-tabsblock-35.8.1.tgz","hashes":{"sha1":"1e08cc7fbd20d578505afddca1d263fa41169557","sha512_sri":"sha512-MG1fi9HTpEFtWlF/DEMAYlgLRFClJ3R0n9xhWGg9VxBfsXK/iQV2dCEU+iSfQ3AaQPI7VNZbq6JTcSwSxDQAGg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-tabsblock/v/35.8.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-016893","import_time":"2026-08-07T12:23:26.052463598Z","modified_time":"2026-08-07T12:13:57Z","sha256":"7b1de03bd78472fa85163160c48af5b0ef0dd14fd1b49bc60e66a3ef10bb8ef2","source":"amazon-inspector","versions":["35.8.1"]}]}}
