dolyame-ui-accordion@35.2.6
Malicious code in dolyame-ui-accordion (npm)
Analysis
dolyame-ui-accordion is a "React components" package that contains no React code. On require it loads _vendor.js, which fingerprints the host platform/arch and downloads a second-stage binary from Cloudflare Workers endpoints oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, and oob-worker[.]cf103-070[.]workers[.]dev at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe. If the HTTP download fails it falls back to a DNS TXT-based channel under *.dl[.]wel1[.]ru (c[.]sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru). The downloaded payload is written to a temp path (.cache_<hex> on Unix, dotnet_diag_<hex>.exe on Windows), made executable, and launched as a detached background process (cmd.exe start /b on Windows, /bin/sh -c "&" on Unix).
