“Want proof? Just visit any of a dozen or so thriving cybercrime forums, websites that mirror the services of Amazon.com and the efficiencies of eBay. Criminal buyers and sellers convene at these virtual emporiums to wheel and deal in all things related to cyberattacks — and in the fruit of cyberintrusions: pilfered credit and debit card numbers.”
Being proactive is really the only security you can have these days. Watch your credit card accounts, periodically cruise you bank accounts for rogue withdrawls, pay attention to the latest massive financial organization account loses. DO NOT GIVE CRITICAL INFORMATION TO SOLICITING CALLERS. If you must do business over the phone, hang up with who ever has called and called them back. But it is best to NEVER make transaction with someone who has called you. No matter how good it sounds, it is just to easy to fake telephonically. This goes for email as well.
