Operation Soft Cell - a worldwide campaign against telecommunication providers

Wednesday 2 October 16:00 - 16:30, Green room

Amit Serper (Cybereason)
Mor Levi (Cybereason)
Assaf Dahan (Cybereason)



In 2018, we investigated what seemed to be a single breach in a large telecommunications company. In the process of assessing data from the breach, we began to see signs of a larger attack campaign and identified the attacker as a nation state actor. Over the course of six months and through multiple waves of attacks, we were able to observe the tools and methodologies used by the attacker, recognize what data they were after, and at times watch the attacker operate on the network with admin privileges. We were able to determine that this attack was far more widespread and far reaching than it appeared. By using various techniques such as OSINTing and cross-correlating data from tools dropped by the attacker across multiple threat intel platforms, we discovered that the attack was part of a much larger, broader campaign against telcos.
 
In this talk we will discuss the tools the attacker used, the techniques used to infiltrate, and how we were able to find campaigns against other companies by the same actor. Attendees will leave this talk knowing more about nation state-backed APTs, attacker TTPs, and our methodology for correlating data and uncovering such campaigns.
