The Federal Bureau of Investigation has launching an study into the recent cyber-attack on Gawker Media's commenting system.

The attacks on Sunday, by a group known as Gnosis, led to the theft of 1.3 million Gawker member usernames and passwords. This led to some members having their Twitter accounts taken over by spammers.

According to The New York Post, FBI investigators are scheduled to meet Gawker Media CEO Nick Denton.

“We need to improve our internal procedures for the sharing of administrative passwords. And improve the encryption of passwords in case the user database is ever compromised,” Denton said in a statement to The Post.

Gawker Media runs gossip websites related to the entertainment world and the technology sector, Gawker, Gizmodo and Jezebel.

The hackers gained entry into the company's commenting system and stole 1.3 million of the 1.5 million user names and passwords that were stored. The hackers publicly posted around 200,000 e-mail addresses belonging to Gawker users.
