Black Hole normally sells for $1,500 for an annual license, and is one of the more powerful attack toolkits on the market right now. The Black Hole exploit kit is somewhat newer and less well-known than. attackers for major Web-based attacks for the last few months. Like the leak of the Zeus source code, the availability of Black Hole for free does not bode well for site owners and defenders. The free version is not the most up-to-date one and likely doesn t have the most current exploits.
