Convicted hacker Robert Moore, who is set to go to federal prison this week, says breaking into 15 telecommunications companies and hundreds of businesses worldwide was incredibly easy because simple IT mistakes left gaping technical holes...Moore said what made the hacking job so easy was that 70% of all the companies he scanned were insecure, and 45% to 50% of VoIP providers were insecure. The biggest insecurity? Default passwords. "I'd say 85% of them were misconfigured routers. They had the default passwords on them,"..."All it takes is one bad access point and they're in," he noted. "The weak link -- you find that one point and all the security unravels...You only have to have one default password and all your security is at risk."
