The Latest in IT Security

A computer security firm has uncovered data it says belongs to some 152 million Adobe Systems Inc user accounts, suggesting that a breach reported a month ago is far bigger than Adobe has so far disclosed and is one of the largest on record. LastPass, a password security firm, said on Thursday that it has found email addresses, encrypted passwords and password hints stored in clear text from Adobe user accounts on an underground website frequented by cyber criminals. Adobe said last week that attackers had stolen data on more than 38 million customer accounts, on top of the theft of information on nearly 3 million accounts that it disclosed nearly a month earlier. The maker of Photoshop and Acrobat software confirmed that LastPass had found records stolen from its data center, but downplayed the significance of the security firms findings.
