Cellebrite, an Israeli maker of phone hacking devices, was recently hacked and 900 GB of stolen data was made available to online magazine Motherboard. The cache, says Motherboard, includes details of login and passwords relating to customers of the my.cellebrite domain and technical data of Cellebrite products.

The hacker, who spoke to Motherboard, did not clarify the extent of the breach but said access to Cellebrite systems had been exchanged among a few participants in IRC chat rooms. Stolen files have not been made public.

"To be honest, had it not been for the recent stance taken by Western governments no one would have known but us," he added.

Cellebrite has advised its customers to change their passwords. Hacked data indicated that apart from US, the Israeli company sells its technology to countries like Russia, UAE and Turkey.

Confirming the breach, Cellebrite said: "Presently, it is known that the information accessed includes basic contact information of users registered for alerts or notifications on Cellebrite products and hashed passwords for users who have not yet migrated to the new [user account] system."
