32 million user names and password were cracked on the social media platform Twitter this week. Leaked Source says malware may have been one of the culprits.

FOX's Jessica Rosenthal reports:

Twitter says they weren't hacked. So what happened? Apparently a site called Leaked Source which has records of people's credentials, says it got copies of users information from someone who gave them similar data from a hacked Russian social networking site.

Leaked Source says it appears malware was used to collect data from different web browsers to the tune of 32 million user names and passwords.

A Twitter spokesman says they're working with leaked source to see if this is what happened and if the usernames and passwords they claim to have are authentic.
