If the HTTPS fetch fails, the shim falls back to a DNS TXT covert channel under *.dl.wel1.ru (sdk/ext/pkg/net subdomains), retrieving a chunk count from c.<domain> and reassembling numbered TXT records via base64 into the same executable. Execution is gated by a TTL state file '.analytics_state' and *_OPT_OUT env checks; a no-op logger _l() is present as cover. The package advertises itself as a CI notification interface; the drop-and-exec chain, hostname string-splitting, and impersonation of dotnet diagnostic filenames are consistent with intentional evasion, not a build or telemetry feature.\n","affected":[{"package":{"ecosystem":"npm","name":"delivery-ci-notify"},"versions":["35.2.5"],"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":"_shim.js","sha256":"f44346e66d2196684de37c27a18d8364cd1ecb314828d6bb167b1bd6b97cc3bb","tlsh":"36a1b75616a670198bb09be58717441af65bf6633380c288fb5ca5981f7262483b2efc"}],"package_integrity":[{"filename":"delivery-ci-notify-35.2.5.tgz","hashes":{"sha1":"3f714b6455b24816eb67913d7b71083de6334fba","sha512_sri":"sha512-CjUVmIP8RSRH8CAKox4L44hzYECIQ49QCH7lqSjClQRmmrEDH632Md30tbdOqv7hh4D1KbZHG+g2gld/nmgpKg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/delivery-ci-notify/v/35.2.5"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015095","import_time":"2026-08-05T14:20:01.429937302Z","modified_time":"2026-08-05T13:55:34Z","sha256":"ebf92bb7d56497b7cc6eb6b7b04a210fb531faa624a9c1b97e830fbf745d6258","source":"amazon-inspector","versions":["35.2.5"]}]}}
