An unidentified hacker, known only as Deus, has revealed on an internet forum that he has hacked into the systems of the giant Israeli communications firm Voicenter and stolen 15 terabytes of data, local media reported on Monday. The hacker put the information up for sale, posting hundreds of examples of the private data that he has taken.
Ynet News said that the major cyberattack hit Voicenter on Saturday. The attack paralysed the communications systems of a number of firms that receive services from the company. It added that software giant Check Point, mobile network operator Partner, Mobileye, Expon, we4G, SimilarWeb, AllJobs, and Gett are among the companies that work with Voicenter.
The company sent SMS messages to its clients on Sunday, saying that the perpetrators of the attack were "hackers from abroad." However, Voicenter claimed that the attack did not affect its work. "As far as we know, the incident did not entail any information leaks."
However, according to Ynet News, many of Voicenter's clients, including we4G and Expon, reported customer service malfunctions following the hack.
It is not for the first time that Israeli firms and private and public institutions have been targeted by cyberattackers.
