Description
The npm package 'booking-tasks' version 1.0.2 contains a malicious postinstall script that executes a VBScript payload on Windows systems. This payload decrypts and runs a PowerShell loader via process hollowing, enabling arbitrary code execution on the host. The package's declared functionality contradicts the presence of this malicious installation script, indicating the main module acts as a decoy. The payload uses multiple cryptographic primitives and chunked Base64 encoding to evade static detection.
