Full disclosure is the only proven method for real-time delivery of security vulnerability information. Freedom of speech assures that they will continue to exist, and the practical operations of the Internet ensure that even a misguided attempt to suppress them will be fruitless. Without them, there would be a void of intelligence regarding the threat to our networks. However, we need to remember that we can't trust them. For the same reasons that certain bomb components and ingredients are considered controlled substances, so should hacking information be restricted.
Information is the first component of the process to make destruction.
I say leave them alone, let freedom ring. We use those same tools to test our security and increase our awareness of what vulnerabilities are being exploited. Orr These sites and zines are indispensable to fighting cybercrime. They report the cutting-edge techniques, flaws and vulnerabilities even before the infosec industry press does. The information provided by hackers is often reliable and detailed, which is not often the case with the standard industry publications.
