The new reports say about hijacked WhatsApp accounts in Israel and the government forced cyber-security agency to send out a nation-wide security alert on Tuesday, ZDNet has learned. After the effects of this, Israel National Cyber Security Authority alerted a new method of hijacking WhatsApp accounts using mobile provider’s voicemail systems.
The new hacking method was first reported in the year 2017 by an Israeli web developer named Ran Bar-Zik says ZDnet. The report explains that if the voicemail users with their phone numbers do not change their account’s default password which is usually either 0000 or 1234, then these types of WhatsApp account owners are the main victims of hackers.
How its work?
According to Ran Bar Zik, WhatsApp will send a security SMS code to the given handset number for authentication for security protocol. After this, WhatsApp let to the users to verify the account using a ‘voice verification’.
For this, WhatsApp will call the user’s number and speak the one time password. If the user is not attending the call, the call with the code goes to the voicemail account. At this time the hacker enters the correct pin to get the code. This will let the hacker use your WhatsApp account using your own number without any permissions.
What’s the solution?
You can simply change the password of the voicemail account to something more complex to prevent the hackers from performing the above-mentioned task. Then the second solution is, you can enable two-step verification system to make your account more secure.
According to the researcher Martin Vigo, this flaw can be used to gain access to user’s Facebook, Google, Twitter, PayPal, eBay and even WordPress accounts. So the users must have to secure their accounts. And the companies must bring a new solution to prevent this flaw.
