A hacking group called Team Bletchley has stolen thousands of files from the CIA’s servers and published them online.
But the CIA was forced to shut down its own network, according to new reports.
The group’s leader, James Bletches, allegedly stole a large amount of data from the agency’s computers from December 2015 to May 2016, according a report from Wired and The Daily Beast.
Bletchers claimed the data was from the Defense Department, the National Security Agency, the Defense Intelligence Agency and the Central Intelligence Agency, Wired reported.
The report does not identify the CIA employees or the files that Bletcher allegedly stole.
The CIA declined to comment on the report.
The hacking group also claimed to have created a strain of ransomware that targets Windows machines.
It’s not clear if the ransomware was based on malware that was published online by Team Bletsky or if it was created by the group itself.
The reports does not say which versions of Windows were affected.
Bletchers reportedly used a program called Zeus to upload files to his server, which the group uses to host its hacking operation.
The files are encrypted, and once decrypted they are encrypted with a password.
However, when the password is revealed, it shows that the files have been downloaded.
The malware is believed to be a variant of a ransomware called Win32.
Bletsky was arrested in September on charges that included unauthorized access to a protected computer, and his case is expected to go to trial later this year.
The government has not said if it plans to seek a maximum sentence for Bletcks.
