dolyame-ui-popup@35.8.7

Analysis

dolyame-ui-popup is a trojanized package that drops and executes a remote binary on load. Requiring the package runs _helpers.js, which fingerprints the platform, then downloads a platform-specific binary over HTTPS from attacker-controlled Cloudflare Workers hosts (oob-worker[.]cf102-baf[.]workers[.]de, oob-worker[.]cf99-9b3[.]workers[.]de, oob-worker[.]cf103-070[.]workers[.]dev). If the HTTPS download fails it retrieves the payload via DNS TXT records from *.wel1[.]ru domains (sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru). The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under TEMP on Windows) and launched as a detached background process (cmd.exe start /b on Windows, /bin/sh -c "path &" elsewhere). A marker file at /tmp/.analytics_state (or TEMP\analytics_state) throttles re-execution. The package also ships an 81KB decoy file (lib/telemetry.js) that masquerades as an analytics SDK.
