volna-boxy-di-test @20.3.8

Summary

On require, index.js loads _compat.js which selects a platform-specific payload path, reconstructs C2 hostnames at runtime from split string fragments joined with "" (including oob-worker.cf10*-*.workers.dev variants and a *.dl.well1.site DNS TXT chunked-base64 fallback), fetches unpinned unhashed bytes over HTTPS, writes them to /tmp or %TEMP% under disguising names such as.cache_<hex> and dotnet_diag_<hex>.exe, chmods 0755 on Unix, and spawns the binary detached via /bin/sh -c or cmd. The User-Agent is spoofed to node-fetch/2.6 to blend with legitimate traffic, a TTL flag file (.analytics_state) suppresses re-execution, and env gates (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) plus cover-story comments ("telemetry", "analytics", "Skip in CI") mask the dropper. The package presents itself as a test harness; the fetched code, the hosts, and the disguised filenames do not match that stated purpose.
