Using cracked software is a direct violation of PortSwigger’s End User License Agreement (EULA). It is considered software piracy and is illegal in most jurisdictions. For professionals, this can have severe consequences. Users who have been caught using cracked versions report their IP addresses being blacklisted by PortSwigger, meaning that even if they later purchase a legitimate license, their device may be flagged as “previously in violation”.
