What goes around comes around.

Hackers have breached SyTech, a contractor for FSB, Russia’s national intelligence service, from where they stole information about internal projects the company was working on behalf of the agency — including one for deanonymizing Tor traffic.

The breach took place last weekend, on July 13, when a group of hackers going by the name of 0v1ru$ hacked into SyTech’s Active Directory server from where they gained access to the company’s entire IT network, including a JIRA instance.

Hackers stole 7.5TB of data from the contractor’s network, and they defaced the company’s website with a “yoba face,” an emoji popular with Russian users that stands for “trolling.”
