Pentagon data breach exposes records of over 3M people

You can change a password after a breach.

You can cancel a credit card.

But when your Social Security number gets exposed, you could be dealing with the fallout for years.

That is the concern after a major breach involving the Pentagon's Defense Manpower Data Center.

If you have served in the military, worked for the Department of War or have other ties to the military community, your information could be among the records involved.

A War Department official told CyberGuy that 2.76 million living individuals and 294,000 deceased individuals were affected.

Depending on the person, the exposed information can include Social Security numbers, names, dates of birth, contact information and military personnel details.

So, if a breach letter from the Pentagon shows up in your mailbox, don't toss it aside.

Here's what happened, what may have been exposed and what you can do to protect yourself.
