Two Twitter accounts associated with the hackers who claim they got into the personal email account of CIA director John Brennan are now inactive.
One account, which had posted a spreadsheet of current and former intelligence officials, containing email addresses and social security numbers, became inactive late yesterday. The second, used by a hacker calling himself "Cracka", went down this afternoon.
About an hour before it became inactive, the hacker posted a Tweet with one word: "bye."
Before shutting down, the Twitter account linked to other sites, which displayed what purported to be a recent log of phone calls made by Avril Haines, a former CIA official. The hackers had previously posted what they claimed was an earlier Haines call log.

Federal officials are looking into reports that a personal AOL email account belonging to Brennan may have been hacked by a high school student, a senior official told NBC News on Monday.
Questions over a possible hacking of a private email account belonging to the CIA director arose late Sunday after the New York Post published a story in which a hacker claimed to have gained access to the account. Described by the Post as a "stoner high school student," the individual claimed to have taken documents that included the Social Security numbers of top intelligence officials, among other information.
Senior officials confirm to NBC News reports that among the documents that may have been taken is a Standard Form 86, which is used in applying for security clearances. The lengthy document includes intimate details on the applicant's personal life, as well as information on family, friends and business contacts.
The senior officials tell NBC News there is no indication any classified material was taken.
