Downloading software from unauthorized sources presents severe technical and security risks:
- Malware and Trojans: CAD software files are large (often gigabytes), making them perfect vectors for hiding malware. "Keygens" (key generators) and patch files are frequently flagged by antivirus software as Trojans. A study by the University of Maryland found that pirated software is a leading vector for ransomware attacks.
