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. Kudos for Washington Post: they went looking into this.
After little research taking me 50 years back in time, I will explain the technology behind and demonstrate that one does not need NSA resources or an army of hackers to repeat the trick on you.
The calling protocol that is used for one network to “talk” to another was developed in 1970’s and is called SS7. The protocol was somewhat refined around 2000 with a SIGTRAN specification, which made it IP network environment friendly. This, however, meant that all the weak links on the upper level of SS7 infrastructure were carried over.

Picture that the communication is made possible not by one, but in fact several hundreds of links, which result a chain that triggers phone on the other end of your call ringing. Referencing back to my earlier post on “Evolution of Authentication”, I would like to demonstrate that the same principle of security level assessment applies here: the chain is as safe as it’s weakest link. Consider WhatsApp hacking methods, message virus trends, phone number exploits, Skype lock services.
During my time in Deutsche Telekom Consulting, I was involved in review of a number of networks (fun times included climbing down sewers following copper lines laid there in 50s-60s-70-s, which were used by corporations and governments in 2003-2004 and likely still to be in place). The hardware and software providers vary from network to network and are extremely segmented, which leads to a simple result: they have to keep their chains wide open to make sure that the next chain link can integrate.
So did anyone know about these vulnerabilities until 2013? In short: of cause. First reference I have discovered dates back to a report published in 2001, which I (admittedly) could not read to full extent due to my neglected Swedish. Google Translate may help you.
It was also made public by Tobias Engel during a Chaos Computer Club Congress held in 2008, when Tobias made a live demo of tracking abilities:
A white paper on SS7 hack SS7: locate track manipulate (pdf file; original here)
And, of cause, it was most widely reported during NSA scandal involving Edward Snowden, that revealed how NSA was exploiting the weaknesses of SS7 to create a very intelligent and complex series of solutions enabling them to simultaneously track and analyse millions of citizens without their nor carrier’s knowledge or approval.
SS7 hack software
So what does one require to make this work? The list is quite short:
- Computer
- Linux OS
- SDK for SS7
Apart from the computer itself, remaining ingredients are free and publicly available on the Internet.
It may have slipped under your radar, but apparently now there is a legal way to use this technology to track anyone worldwide, and NSA is not involved at all: the service offering is open to public and provided by a NASDAQ listed Verint Systems Inc. (NASDAQ: VRNT). In their product description, which was made public, they refer to the system as “Skylock”. During search I even stumbled upon a certification of encryption capabilities of this product by NIST (certificate scan).
Verdict? Abandon illusions of privacy if you still had them.

Disclaimer: this article is a warning to regular citizens about low technological barrier protecting their privacy specifically in relation to mobile phone hacking using ss7 protocol. It is not a guide to hack-a-phone. I will intentionally leave a few aspects uncovered. I urge all readers NOT to use this technology and hope that the solution to restrict this ability to track phones will be implemented soon.
SS7 hack or signaling system 7 hack is the process of getting calls or SMS for an actual subscriber, on another mobile number, or in an application. For many services (e.g banking etc.), a person is verified by using SMS or a call. If somehow call and SMS can be routed to another number then it is possible to hack.
We will explain, the ss7 protocol and call flow for getting calls and SMS over another number/application.
Ss7 vulnerability exposes the network for SMS and voice hack. Along with this, once access to the ss7 network, the real-time location of a person can be obtained.
SS7 is the traditional network that uses standard ISUP and MAP protocol for call and SMS.

SS7 hack is not simple as it looks, people claim to install software and then just enter phone number to hack SMS or calls. Getting calls and SMS via a hack is the process to connect to the ss7 network and run an application so that the home network of an original subscriber gets the impression that software is the roaming VLR/MSC node in a network. The first step is to get the ss7 connection.
Get an SS7 Connection for the hack:
Get SS7 Global Title and Point Code: For an SS7 connection, one should have a Global Title and a point code (international), a local point code (local, between you and mobile operator )can be used, depends on the ss7 connection provider. If one is a mobile operator, then get this from the standard GSM body. New network code is assigned by gsm so that you can have a big range of global titles or MSISDNs and IMSIs.
If not a mobile operator, one can take a global title on lease from a mobile operator. Once you have GT, now there are the following options.
SS7 connection via an aggregator: In this, you can connect to an SS7 aggregator and they can publish you GT, on all networks. So any traffic coming to your GT will be forwarded by aggregator towards your node or application. Mostly MVNO does this, they have GT ranges, those are published to an aggregator for connecting mobile network operators globally.
Directly with a Mobile Operator: In this, you will have direct links with mobile operators, each will set routing for your GT, towards the serving node. In this, you need to connect each mobile operator Individually.
SS7 vs Sigtran:
Ids install software. If you are using pure SS7 (E1/T1), then the box with the application should be on the premises of mobile operators. If using SIGTRAN, which is IP based, You can have your box in a data center on the cloud.
Ss7 hack tool or Software:
Once one has an ss7 connection. Now time to develop an ss7 application over GSM MAP signaling. SDK for ss7 provides the required ss7 stack and libraries for developing ss7 hack software. Before developing the application first finalize the requirements. If one wants to receive SMS, then the application should be developed to handle protocol messages for SMS. Now the ss7 application will simulate as it is a real device.
Application Registration as a real phone:
The first step is to register the application as a phone registers in the roaming network. This required the IMSI of the sim card, to which the mobile number belongs. Mobile number everyone has but IMSI don’t. So the first step is to get IMSI. Hacking Application sends SRI-SM with the phone number to the HLR, which sends IMSI and roaming information in response. Roaming information includes the county code and area code.
From IMSI the application builds the location update along with other parameters. Then open a TCAP dialogue to the SS7 node. The open dialogue needs to fill SCCP called party address and SCCP Calling party address. Called Party address is derived from IMSI and calling party address is the GT of software application.
During Update Location, HLR will respond with ISD or Insert Subscriber Data. The software application needs to acknowledge the ISD to the HLR, else update location procedure will fail and the application will not attach as a phone. One HLR sends update location ACK, which means registration is done.
SS7 Hack for SMS:
Once the application registered with the home network. The global title of ss7 hack software updated on the home HLR as an outcome of update location procedure. When a request for authentication for mobile terminated SMS starts. HLR gets SRI-SM query from the hack application, in the response of SRI-SM, HLR sends have visiting MSC number and IMSI. In our scenario, the MSC number is the GT of the application. The sender SMS will send the SMS to the software application using the MSC number. Now its applications responsibility to decode the message and display the message as a user-readable string. Now you have the authentication code you were looking for.

SS7 Hack for Voice:
For voice, after phone registration call flow. The hack software should activate the call forwarding to the new number. While activating call forwarding, the ss7 hack tool can send the type of call forwarding and the mobile number where the hacker wants to receive the call. The call forwarding type can be “Call Forwarding Unconditionally”. This will enable call forwarding all the time. In this case, even the mobile user never comes to know that his call has been hacked. After voice verification, the call forwarding can be removed.

SS7 hack applications examples:
Any application which required user verification from SMS or voice can be hacked by the ss7 network. We will cover the ss7 call flows for WhatsApp and Facebook.
ss7 hack Whatsapp:
Whatsapp is used everywhere. It does the message and file transfer over the IP network. It connects your phone book to the others using phone numbers. So no need to add a contact explicitly. Like in skype, we need to create an account and need to add other skype ids before any communication. But with this app, the phone number is the profile id. While installing WhatsApp it requires user authentication via SMS. If WhatsApp needs to hack, after installation, run the ss7 hack software app and received the authentication message on the hack software app. Enter the code in installed WhatsApp. Now you can have messages on your WhatsApp, while the number belongs to another guy.
ss7 hack Facebook:
Facebook also does authentication via SMS. One can get SMS on an ss7 hack software.
