For those who don’t know, Whatsapp and Telegram both apps are end-to-end encrypted, and enable 256-bit encryption, this means that could take months to decode a single sentence.
This two apps suffer from same hardware vulnerability which means that can be hacked to seize control both Whatsapp and Telegram. And about Facebook, it doesn’t matter how strong your password is, hackers can access your account with your phone number.
The flaw rest in the SS7 (Signaling System 7), this is a set of telephony signaling protocols, which is used to set up and tear down most of the world’s Public Switched Telephone Network (PSTN). It also performs number translation, SMS (Short Message Service), local number portability, prepaid billing, and other mass market services.
But don’t worry, this technique is also very, very complicated to use, it take a lot of time and is more easy hack your accounts by other way, so we recommend to erase your phone number of your Facebook account and never (Never!) write down important and privacy information on Whatsapp and Telegram, like credit card numbers, social security numbers and other personal information that can be used to steal your money or worse, your identity.
We also recommend to use strong passwords, never use words, dates and names related to you, this is the easiest way to hack your accounts, is better that you use random words, with at least a capital letter on it, a number and a symbol of your preference, but never substitute a letter for a number, example, “House” for “H0us3” this is too obvious and can be hacked.
