What is ss7 attack ?

Hello friends today I will tell you what is ss7 attack ?

Before that, let us know what ss7 is -

ss7 means 'signalling system 7' is a kind of protocol. Let's say with an example in easy language, assume that someone is a network provider named (A) and he provides the people with a singling system and one day he makes a call or text message to someone named (B). The process that calls or text messages between a network provider named (A) and a person named (B) or what works between them is called ss7.

Now let's talk about what ss7 attack is - 

friends germany karsten nohl in 2014, who was a researcher he used to work for a network protocol company, he brought ss7 in front of the world there is some flaw inside ss7 and if they If not fixed, hackers can attack hacking on ss7, if that company did not believe them, then they proved hacking attack on ss7 in 60 minutes to prove this flaw, then the world came to know how to attack it. is .

Have you ever heard that someone's call recording or otp has been hacked, this work is done with ss7 attack, now let me explain you with an example that suppose someone is a person named (R) and he is a person named (L) Is making a call and when the call of a person named (R) goes to a person named (L), you do not believe that the call goes directly to the person named (L), that call first means that tower A person named (R), who owns a cellular network, first connects the system, then goes to a person named (L) and when a hacker comes in between them, a person named (R) calls his The cellular network used to go to a person named (L) through the company's system, now it will go to the call hacker because the hacker breaks the connection between the (R) and the network company system and creates its new network. Now when a person named (R) calls from a person named (L), that call will first be connected to the hacker network and then that call will go to the person named (L), meanwhile the hacker hacks their call.
