Document-sharing website Scribd announced this week it was hacked, the victim of what it s calling a deliberate attempt to access the email addresses and passwords of registered Scribd users. The San Francisco-based service claims it noticed and blocked suspicious activity earlier this week but asserts that only a fraction of its users may have been compromised by a breach. Scribd salts and hashes its passwords, a routine that the company believes that only less than 1 percent of users were affected.
