Just a phone number can help hacker compromise your personal data,
the latest in cyber-attack world is hack on WhatsApp’s web based
services. WhatsApp has become a channel for a lot of people to
communicate free of cost.
WhatsApp web is the latest which is a browser based service that is
rendered via smartphones and computers instead of app. The recent hack
has up to 200,000 user’s personal data with them.
To attain more information hacker’s used to send Vcard’s to
non-planned numbers they had with them which was reported by a security
firm.
V Card is an electronic contact that is used to send information
regarding contact details of someone in your contact list. The v card
that were send by hackers had a malicious code in it that would dispense
bot, ransomware and other remote access tools (RATs) on the sender’s
phone or the system they are using.
Bots can harm in a different way by slowing down the system and
asking them for ransom and to regain access to their own personal data
whereas RAT has altogether a different concept of getting a remote
access to a device.
A security firm checkpoint revealed that this WhatsApp vulnerability
can be easily exploited without the use of any hacking tool. The public
got to know about such vulnerability related to WhatsApp later on august
27 whereas the same got fixed before some days ago on august 21.
Oded Vanunu who is group manager at security research group has
appreciated WhatsApp for taking such quick and responsive decisions on
this vulnerability and deploying an initial alleviation against
exploitation in his blog post.
This was much needed step as WhatsApp has over 900 million active
users with around 200 million for web –based version of WhatsApp.
