TJX Companies Breach
A Miami-based hacker was sentenced to 20 years in prison for carrying out the attack that bilked TJX Companies of millions of credit and debit cards. Albert Gonzalez and others used a hacking technique called wardriving, targeting weak wireless implementations at TJX, OfficeMax, Barnes & Noble and other stores. The high-profile data security breach served as the poster child for the need for better security controls to protect sensitive data. The case also pointed out the need to carefully deploy wireless LANs with appropriate protections. In total, more than 45 million credit cards were stolen.
