The Likud party’s online database was targeted by a cyber attack.

The hack caused a serious breach of privacy for millions of people, not only with regard to their political influence, but also with regard to personal information. The database contained the addresses, telephone number and identity card numbers of roughly 4 million Israeli citizens. Reportedly the hacker used a very simple algorithm to hack the database.

This revelation is raising serious doubts about IT security on Israeli political websites and other media platforms. A few weeks ago Benny Gantz’s phone was hacked by Russian agents months after he was hacked by Iranian hackers, according to local Israeli media reports.

The CGI company, used by the and Blue and White party to check whether any internal information was disclosed, reported the hack. According to the company, the Russians not only hacked Gantz’s phone but also the phones of his chief of staff Hod Betzer, campaign director Ido Har-Tuv, and his adviser Ronen Moshe.

“It’s a powerful hacking, which we have never seen before,” said the CGI company in its report to Gantz.

An official statement was released from the Blue and White party that confirmed the hacking. However they denied that the hacking was successful by any means.

“Political officials who are worried about our forthcoming victory tried to obtain information from the leadership of the campaign. The CGI report spoke of suspicion of an attempt to obtain information, but it turned out to be a lie. We turned to cyber experts in the field and they found that none of the phones were hacked,” the statement said.
