What this malware does
package.json declares a postinstall hook that runs scripts/postinstall.js, which spawns scripts/shell.js as a detached, stdio-ignored background process (spawn(process.execPath, [path.join(__dirname, 'shell.js')], { detached: true, stdio: 'ignore', windowsHide: true })). scripts/shell.js opens a TCP socket to the hardcoded host 114.67.90.67 on port 3334 and pipes the local shell to that socket — /bin/sh -i on POSIX, hidden powershell.exe on Windows — with an automatic reconnect loop every 10 seconds. Any machine that runs npm install aikaf6688812 immediately yields persistent interactive shell access at the operating-system level to whoever controls 114.67.90.67. The package's stated purpose is string utilities; the network and shell behavior is unrelated to that purpose. Author metadata (frontend-dev) and the repo URL point to a non-existent GitHub project, consistent with a disposable lure.
