The SS7 signaling system is often called the nervous system of a phone network. Before the invention of SS7, service commands for subscriber connection and data packet delivery were transferred via a speaking channel. This approach was upgraded and replaced with the global signaling system (SS7) over 30 years ago. SS7 is a set of protocols allowing phone networks to exchange the information needed for passing calls and text messages between each other and to ensure correct billing. It also allows users on SS7 hack explained. Technology is, in its nature, developing based on current progress. Sometimes it is worth going back to the blue box era to discover something in today's world. More or less recent scandals involving NSA's practice to track, listen, and intercept communication without authorisation made a splash, but not many took the time and effort to understand the magic behind. (If you don't know what SS7 is, you may want to start here.) Although SS7 networks have been vulnerable since inception, the risk of SS7 based attacks on mobile networks have been gaining a lot of attention in the public media, both in the United States and overseas. The GSM Association's (GSMA) Fraud and Security Group has recently categorized SS7 vulnerabilities in a comprehensive document SIGTRAN is a group of protocols for transporting signaling (SS7) over IP networks. Each protocol in SIGTRAN logically replaces a protocol in the SS7 stack (for example M3UA replaces MTP3).. Example capture file. Example of GSM MAP packet captured on a TDM link.

SS7 Vulnerability Isn't a Flaw — It Was Designed That Way

SS7 Mobile Application Part (MAP) protocol has been introduced for mobility support in 2G networks and is still in active use. Flowcoder allows to simulate any SS7 MAP network node and assure SS7 security. INAP, CAP, ISUP are also supported. Every SS7 network interface can be simulated packet-by-packet with any standard and non-standard packets
