If the HTTPS mirrors fail, _bridge.js falls back to a DNS TXT-record channel against tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, and win.dl.well1.site, querying c.<domain> for a chunk count and then <i>.<domain> for base64 fragments that are concatenated, decoded, written to disk and executed as a native binary. The package's README advertises only a trivial in-process logger; the hostname obfuscation, per-OS payload selection, hidden temp staging with system-tool-mimicking names, detached spawning, and DNS-tunneled code delivery are exclusively attack behaviors and produce full-host code execution on any consumer that installs or requires this package.\n\n## Source: ghsa-malware (3c365a082f023a4fd7afb285809fc3faa40f26ef671ef9fded73a2e6f82f0233)\nAny computer that has this package installed or running should be considered fully compromised.
