The Federal government just busted what it says is the largest credit card hacking scheme ever.
It lasted for seven years, affecting millions of Americans.
The Justice Department says credit card numbers were stolen from the databases of 7-eleven, JC Penney, Jet Blue and other major companies. Even Wall Street was hit.
Prosecutors allege the suspects then sold the numbers to other criminals for as little as $10 apiece.
"This type of crime is really the cutting edge of financial fraud,” said Paul Fishman, U.S. Attorney for New Jersey.
Investigators the best way to avoid becoming a victim is to check your credit card statements regularly, and report any suspicious purchases immediately.
