WhatsApp: A new malware attack?
Whatsapp has been the top instant messaging app yet. With 1.5 billion users, it’s responsibilities have also increased. The most important one is providing more security than before. As some of the malware attacks had happened on WhatsApp before by some hackers. Some caused the user to lost his data. Just last September, a malware attack by using a GIF image was complaint to WhatsApp by Check Point, which was resolved quickly. But this time the attack is a bit stronger.
The attacker will send you a message in a group chat. If you open that then your WhatsApp will stop working and would crash. It would keep on crashing as long as you are trying to open it. Your action will cause the same problem with the other members of that group. The solution would be to uninstall the app and then re-install it. But the bug will cause you to delete your group permanently which will delete your data related to that group too. Other than that, no message of any individual chat will be exposed to the attacker.
The attacker is supposed to be a member of a group to send messages to the users joined that group. The maximum capacity for the users in a group is 256.
“WhatsApp greatly values the work of the technology community to help us maintain strong security for our users globally. Thanks to the responsible submission from Check Point to our bug bounty program, we quickly resolved this issue for all WhatsApp apps in mid-September. We have also recently added new controls to prevent people from being added to unwanted groups to avoid communication with untrusted parties altogether.” said a software engineer working for WhatsApp.
The users who haven’t update their WhatsApp since September should update as soon as possible to get their data saved from this attack.
“Because WhatsApp is one of the world’s leading communication channels for consumers, businesses and government agencies, the ability to stop people using WhatsApp and delete valuable information from group chats is a powerful weapon for bad actors,” said Oded Vanunu, Check Point’s Head of Product Vulnerability Research, in a media statement.
