Syniverse reported in filings that an unknown individual or organization obtained unauthorized access to the databases of its network several times. The information obtained by hackers used to log in to the system allowed attackers to gain access to most of the important data of the company and its customers. Medium of transmission (EDT) was compromised by 235 of her clients.
Former Syniverse employee who worked on systems EDT, stated that they have information on all types of call data. Syniverse declined to answer specific questions about the scale of the hack and its consequences. According to a representative of one of the cellular operators, the hackers who hacked Syniverse gained access to metadata such as the duration and cost of calls, as well as the number of the caller, the location of the participants in the conversation, and the content of SMS messages.
The company reported that it found signs of a breach in May this year, but unauthorized access to its networks was first carried out in May 2016 of the year. According to the official website Syniverse, the company processes 740 billions of text messages annually and partners with more than 300 mobile operators around the world. Her clients are 95 from 100 largest mobile operators.

Researchers call the five-year presence of attackers on Syniverse networks a global disaster for the privacy of cellular users. It is noted that hackers could gain access to SMS messages from two-factor authentication systems, which allowed them to gain access to the accounts of Google, Facebook, Microsoft and personal accounts of bank customers. A recently discovered attack could potentially affect hundreds of millions, if not billions, of mobile users. Using the data Syniverse possesses, hackers can create a detailed user profile, knowing exactly what they are doing, where they are, who they are calling.
A former Syniverse employee said the attack probably did not significant damage, because over the past five years there have been no obvious events indicating the use of a vulnerability against users.
