Compromised Facebook accounts are for sale. They go in lots of a thousand and the cost depends upon the number of friends in the account. The high end price is forty five dollars for a thousand accounts. There are a million and a half accounts for sale, by just one hacker.
The Facebook accounts are valuable to spread malware:
“… “Once you have the name and address and other profile-type information from a social networking site, you can use it to corroborate your way into debit card accounts and bank accounts through social engineering, ” Howard added. “You could also use these accounts as a platform to distribute malware through the friend system. Even as a security guy, I have to double and triple clutch when it comes to accepting friend invites from people that I do not know.””
If this is just the ‘business’ inventory of one hacker, then one wonders how many Facebook accounts have been compromised. For some Facebook account holders, it is a matter of pride to build up the number of ‘friends online’. Some of those so-called friends may have criminal intent in mind. Networking on a service such as Facebook absolutely requires attention to privacy and security. Without that focus, the Facebook account may end up as part of a hacker’s sales inventory.
