It's recommended that users who haven't updated WhatsApp since September should download the latest version in order to prevent falling victim to this attack. Researchers disclosed their findings to the WhatsApp bug bounty program in August and the rollout of WhatsApp version number 2.19.58 in September fixed the vulnerability.

"It can be a tool for pure vandalism, or to specifically target a group such as political advisors or company executives to disrupt their communications.

While this restores the app to working order, the group and all of the contents within it are lost forever.Įven if all members of the group reinstall the app, any information sent previously is gone, meaning this attack could be used for sabotage – especially given how WhatsApp is used by billions of people around the world. The bug means that the app will continue to crash on an infinite loop when WhatsApp is reopened, meaning that the group needs to be deleted and WhatsApp needs to be reinstalled in order for the application to function again. By sending a message with this altered number, it would then crash the application for every member of the group This time researchers found they could use this technique to alter the identifying phone number of members of the group, replacing the numbers with non-digit characters. However, this is possible via the use of legitimate penetration-testing tools in this case, researchers were able to gain access to WhatsApp traffic and decrypt the secret parameters and turn them into plain text, allowing the attacker to decrypt and modify messages, as was the case in Check Point's previous research into this area. In order to launch the application-crashing attack, the attacker first of all needs to gain entry to the WhatsApp group they intend to target – although given that the chat app allows up to 256 users per group, this might not prove too difficult.Īn attacker would need to have some hacking skills in order to carry out the attack, with the ability to browse WhatsApp Web and open Chrome's DevTools, as well as gaining access to the secret parameters used by the application as part of how group chats operate. It follows on from Check Point's previous research into how hackers could tamper with WhatsApp, which provided security analysts with intelligence on how WhatsApp messages are communicated and how they can be manipulated.
