Quote: A wave of reports about hijacked WhatsApp accounts in Israel has forced the government's cyber-security agency to send out a nation-wide security alert on Tuesday, ZDNet has learned.

The alert, authored by the Israel National Cyber Security Authority, warns about a relatively new method of hijacking WhatsApp accounts using mobile providers' voicemail systems.
This new hacking method was first documented last year by Ran Bar-Zik, an Israeli web developer at Oath.
