bigops-storio-ngrx-component-store@35.3.4

Analysis

bigops-storio-ngrx-component-store@35.3.4 is a trojanized clone of the ngrx/component-store state library. On require, index.js loads _helpers.js, which downloads a platform-specific binary over HTTPS from three Cloudflare Workers origins (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe depending on OS/arch. If the HTTPS fetch fails, it falls back to a DNS-tunneled channel: it reads TXT records from c[.]sdk[.]dl[.]wel1[.]ru (and ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru) to learn a chunk count, then reassembles base64 chunks from numbered subdomains. The recovered binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in the temp dir on Windows), made executable, and launched as a detached background process via /bin/sh -c "<file> &" or cmd.exe /c start /b. A marker file /tmp/.analytics_state throttles repeat execution.
