Watch hackers hijack WhatsApp and Telegram accounts using known telecom flaw.
WhatsApp and Telegram have both billed themselves as secure alternatives to phone, text or email correspondence. For the most part, that’s true, the two are end-to-end (e2e) encrypted by default and because of this, your conversations are much harder to monitor by outsiders.
But, sometimes it’s not the application that leads to security vulnerabilities, it’s something else entirely. In this case, that “something else” is Signaling System 7 (SS7), a global network of carriers that acts as a central hub to connect the world.
SS7 vulnerabilities aren’t a secret. We’ve known about them for years, as have governments around the world, telecoms and yes, hackers. The problem is, the vulnerability isn’t a simple one to fix, but more on that later.
For now, check out the hack in action.
