It's been a while since I was told the story, so bear with me. It was Experian. They shipped tape backups of essentially their entire consumer credit DB, unencrypted, via UPS.
UPS truck got robbed at gunpoint, only one package stolen...

You guessed it, one day their car was stolen, with ALL of our checks/stubs in them. And our SSN's were printed on them too.
We were given a year of credit monitoring at the credit unions, paid for by the company. And they stopped printing the SSN's on them.
