“Viber has confirmed a situation earlier this morning in which Viber appeared to have been hacked by the Syrian Electronic Army (a pro-government group of computer hackers aligned with Syrian President Bashar al-Assad).
AppleSpot originally reported on the hack that affected the Viber support page, though it was unclear the extent to which hackers accessed Viber systems.”
