Abstract (click to view)

The 27th of June 2017, a new wormable malware variant has surfaced. Talos is identifying this new malware variant as Nyetya. The sample leverages EternalBlue, EternalRomance, WMI, and PsExec for lateral movement inside an affected network. The presentation will be divided in two parts:

the first part will describe Nyetya: how it works, the integrated exploits, Doublepulsar modifications, the “encryption” of the infected systems… This part will be focused on the analysis of the malware (reverse engineering)
the second part will describe the incident response performed by Cisco Advanced Services Incident Response in Ukraine focused on M.E.Doc software. This part will contains the techniques used by the attackers to massively compromised M.E.Doc users. A timeline will be exposed and detailed
