Over the last year we have seen an increase in the number of ransomware attacks against large organizations, such as schools and municipalities. In these events, the attackers spend a significant period of time in the network and are able to gain control of a large portion of the network. Once this control is achieved, the attacker can exfiltrate data, steal credentials or even execute ransomware on a large scale. During this talk I will walk through this entire process, which usually involves an initial dropper such as Emotet or Trickbot that is targeted toward an individual user. This leads to using multiple techniques to further penetrate across the network through lateral movement. At this point, sensitive data can be exfiltrated from the network or the attackers can encrypt the data on the network with ransomware like Ryuk, demanding a large ransom. Simply examining a few of the bitcoin addresses show that these attacks have generated Millions of dollars in attacker revenue. Understanding how these attacks operate is key to making sure that your network has the tools and visibility to prevent your network from becoming the latest Big Game trophy.
