Guidance Hacked

The Register reports that Computer forensics firm Guidance Software has itself become the subject of a hack attack, prompting warnings to its clients in law enforcement and computer security that their financial details may have been exposed.

In a letter sent out last week, Guidance warned its customers that a November attack on its databases might have exposed details of its approximately 3,800 credit cards. Guidance stored customer credit details on an unencrypted database along with card value verification (CVV) numbers, a violation of merchant guidelines issued by both Visa and Mastercard. The names, addresses and telephone numbers of clients were also exposed.
