In the wake of the Equifax breach, many people have explored options on additional security and damage control. Putting a security freeze is a step above fraud alerts and can prevent thieves from getting credit in a victim's name, even if they have their social security number. For those under 65 years of age, putting a credit freeze costs $10 (so a total of $30 for all three major credit bureaus). Freezes can be requested by mail or online, and the bureaus must place the freeze within three business days of receiving the message.
Target says that between Black Friday and December 15th, point of sale registers were hacked company wide and over 40 million credit and debit cards were seized.
