The fetched bytes are written to /tmp or %TEMP% under deceptive filenames (.cache_<hex>, dotnet_diag_<hex>.exe,.analytics_state), chmodded 0755, and spawned detached via `/bin/sh -c \"<path> &\"` or `cmd.exe /c start /b`. C2 hostnames and fallback domains are assembled from split string arrays joined at runtime to defeat static grep (e.g. [\"oob-worker.cf1\",\"00-416.workers.dev\"].join(\"\") and ['sdk','.dl.wel1','.r','u'].join(\"\")). A cache-stamp guard prevents re-execution. A co-shipped lib/telemetry.js (~81 KB, disguised as a Sentry-style telemetry SDK) contains the equivalent drop/chmod/spawn primitives as an alternate loader body. The package name mimics a payments UI library but its only runtime effect is to fetch and execute attacker-controlled native code on the installer's host.\n","affected":[{"package":{"ecosystem":"npm","name":"dolyame-ui-popover"},"versions":["35.8.7"],"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":"_ext.js","sha256":"6d0c9b2110056b4ac76cb6d6f6ddb40ea11f15daf551c515259b5b762c26aa41","tlsh":"32a1a69a166670188bb0dbe4ca175816f65bf66333c0c284fb9c65981f7312483b2dfc"},{"path":"lib/telemetry.js","sha256":"2fa2b0c5fb3444a0cb91b488c2e9d6a426936456eed39992c1159c598d6a5eb0","tlsh":"79835056566a142186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"filename":"dolyame-ui-popover-35.8.7.tgz","hashes":{"sha1":"c7646ac080577a6077afba0185b79dbef885c8d2","sha512_sri":"sha512-BExgvIq9XZhKxDAu1sh/9SE+TD9aH/eDP9LUX/joEHhcNZueFdjaItCgLTHFQ9PqOOQdmXRDqu5kvLiSIOYOSA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-popover/v/35.8.7"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015598","import_time":"2026-08-05T15:19:59.730367504Z","modified_time":"2026-08-05T15:11:03Z","sha256":"5ed3996792c8c70963eee2871d056f13b90e873087ff77be677c7cb359058b9f","source":"amazon-inspector","versions":["35.8.7"]}]}}
