Package name 'typescrip-cli' typosquats 'typescript-cli'; index.js exports an empty object and the package has no library functionality. scripts/postinstall.js hides its network destinations and command lines inside four numeric byte arrays that are XOR-decoded at runtime with the key 'stf2026'. The decoded URL is https://github.com/bebra1/qPzM50V1AKG0rVlH/releases/download/null/main.exe (an unrelated personal GitHub account, mutable 'null' release tag). On Windows the script downloads that executable to %TEMP%\main.exe and spawns it detached. On WSL/virtualized Linux it decodes a PowerShell launcher and bridge script and passes the concatenated command to child_process.exec with windowsHide:true, running the same payload on the Windows host across the WSL boundary. In parallel, postinstall POSTs a JSON body identifying the host platform to a hardcoded bare-IP beacon at http://193.70.34.101:20099/vote, with the host string reassembled from a split array ['193','70','34','101'].join('.') to avoid literal-string detection.
