One of the security features that WhatsApp supports is end-to-end encryption. This means that messages sent and received via WhatsApp are encrypted, which in theory means that no one should intercept them and read their content. However, security researchers at Check Point suggest otherwise.
During a recent Black Hat security conference in Las Vegas, several security vulnerabilities were discovered on WhatsApp that allow changing chat messages. This means that, in theory, the hacker can modify the content of the message and make it completely different.
Another drawback is that hackers can change how the sender identifies themselves. This allows the hacker to modify the message to make it look like it came from someone else.
Fortunately, Check Point points out that these security vulnerabilities and security vulnerabilities have been resolved in the meantime, and a Facebook official (owned by WhatsApp) states that the scenarios described are the mobile equivalent of changing e-mail responses and that problems of this type were resolved a year ago.
