OMG... those hackers are complete idiots!
"The hackers claim they know of about 30 unpatched Firefox flaws. They don't plan to disclose them, instead holding on to the bugs."
Mozilla's respose:
"I do hope you guys change your minds and decide to report the holes to us and take away $500 per vulnerability instead of using them for botnets."
Hacker's response:
"It is a double-edged sword, but what we're doing is really for the greater good of the Internet, we're setting up communication networks for black hats."
My response:
30 * 500 = $15,000
Those two hackers could have scored $15,000 to share amongst themselves by simply disclosing information about their findings.
