NPM Supply Chain Malicious Postinstall Script Execution
Detects suspicious process execution originating from npm postinstall scripts, which can indicate a supply chain compromise. Specifically, this rule looks for npm, node, or npm.cmd processes with 'postinstall' or 'plain-crypto-js' in their command line, spawning suspicious executables like curl, wget, python, bash, sh, cmd, powershell, or wt, or connecting to known malicious domains/IPs or specific file names associated with the 'plain-crypto-js' RAT dropper.
