WhatsApp, a popular messaging platform which as of this writing claims to have over 1 billion downloads and Telegram another popular messaging app with over 2 million users may have a vulnerability that allows hackers to take over hundreds of millions of accounts as was disclosed by Check Point. I should mention that this has yet to be proven.
To guarantee user privacy, WhatsApp and Telegram use end-to-end encryption. The encryption is designed to ensure that only the people communicating can read the messages and no one else. Check Point discovered the vulnerability in the messaging services, online platforms of WhatsApp and Telegram. The vulnerability can allow hackers to take over users’ accounts on any browser. As well as access to personal and group messages, photos, videos, contact lists, and shared files. Basically, the hacker has full control of users accounts. Therefore attackers could potentially download any and all of your personal photos, videos, and conversations to even use them against you.
The vulnerability was reported to WhatsApp’s and Telegram’s security team. Both companies have acknowledged the security issue and developed a fix for web clients worldwide.
