![]() ![]() Run DFIR-Orc to extract artefacts on the Windows 10 machine.The different steps and tools used to extract and analyze the artefacts post compromise are: Windows 10 workstations with Sysmon installed,.The Lab is composed of the following elements: This short analysis can be later on used as a reference to build rules to detect Cobalt Strike movements during a forensics incident response (without Sysmon or Audit Policies). Depending on the Cobalt Strike settings used by the attackers, the events generated may be slightly different and detection rules may fail.Įach command was executed twice to avoid false positives, and the investigations were conducted on one of these two executions. ![]() It is important to note that Cobalt Strike allows users to change various settings (pipe names, service name, default temporary process, etc.) to customize its footprint. The tests were done with Cobalt Strike version 4.4 with the default configuration, without any kind of customization. To get a better context and understanding, we enabled Sysmon on the victim workstation, in order to get a baseline to compare with. The aim here is to provide basic information on the kinds of logs and other artefacts that could be generated from Cobalt Strike on a default Windows 10 host. This article will detail lateral movements using the Cobalt Strike Beacon with the following built-in jump commands: The command allows to remotely access and control the compromised system, and to use it as a pivot point for further attacks on the network. This second part will focus on the jump command in Cobalt Strike, used to establish a connection from a compromised system to the command and control (C2) server. The previous article detailed the findings of the Cobalt Strike remote-exec built-in command that allows executing arbitrary commands on the remote host without creating a persistent session with a Beacon. ![]()
