Signaling System No. 7 Protocol is used by all networks worldwide.

SS7 is a set of telephony signaling protocols that are used to set up most of the world’s public switched telephone network (PSTN) telephone calls.


SS7 Attacks

With access to SS7 and a victim’s phone number, an attacker can listen to a conversation, pinpoint a person’s location, intercept messages to gain access to mobile banking services, send a USSD (Unstructured Supplementary Service Data) command to a billable number, and conduct other attacks.

SS7 hacks are mobile cyber attacks that exploit security vulnerabilities in the SS7 protocol to compromise and intercept voice and SMS communications on a cellular network.

Similar to a Man In the Middle attack, SS7 attacks target mobile phone communications rather than wifi transmissions.


Two-factor authentication (also known as 2FA/OTP) via SMS using SS7 is inherently flawed as these SMS messages are unencrypted and can be intercepted.

With the code from the SMS in their hand, a cyber-criminal can potentially reset your password to Google, Facebook, WhatsApp account, or even your bank account.


Call Interception refers to actually intercepting live phone calls taking place on the Target phone, in real time as they happen.

Call Redirect refers to intercepting the phone call and forwarding it to your number in real time.


Being able to track the location of your target is a valuable goal for espionage operations.

The location tracking happens in real time even if the phone GPS is turned on or off.

SS7 Hacking Software

SS7 hacking software takes advantage of vulnerabilities in the protocol to gain unauthorized access to sensitive information and intercept communications. There are several techniques that hackers can employ to exploit these vulnerabilities:

  • Location Tracking: By exploiting SS7 weaknesses, hackers can track the location of mobile devices. They can intercept the signaling messages exchanged between the MSCs and VLRs to determine the approximate location of a target device.
  • Call and SMS Interception: Hackers can intercept and redirect calls and text messages by exploiting SS7 vulnerabilities. They can reroute incoming calls and SMS messages to their own devices, allowing them to eavesdrop on conversations or gain access to sensitive information sent via SMS.
  • Denial of Service Attacks: SS7 hacking software can be used to launch denial of service attacks on targeted networks. By flooding the network with signaling messages, hackers can overload the system and disrupt services.
  • Subscriber Information Extraction: By exploiting SS7 vulnerabilities, hackers can extract subscriber information such as call records, billing details, and even listen to voicemail messages.

How does SS7 Hacking Software Work?

SS7 hacking software works by taking advantage of the inherent vulnerabilities present in the SS7 protocol. Here’s a step-by-step breakdown of how it operates:

  1. Intercepting Signaling Messages: With access to the SS7 network, the hacker can intercept the signaling messages exchanged between different telecommunication networks. These messages contain crucial information, such as call records, location data, and authentication details.
  2. Manipulating Signaling Messages: Once the messages are intercepted, the hacker can modify them to suit their malicious intentions. For example, they can redirect calls, forge SMS messages, or even disable certain services.
  3. Exploiting Network Services: In addition to intercepting and manipulating signaling messages, SS7 hacking software can also exploit various network services. For instance, it can enable the hacker to bypass two-factor authentication systems, clone SIM cards, or perform unauthorized call forwarding.
  4. Covering Tracks: To avoid detection, hackers using SS7 hacking software often take steps to cover their tracks. This includes deleting logs, using encryption techniques, and employing anonymization tools.
