![]() ![]() ![]() These are programs or scripts that an adversary can, with relatively high reliability, expect to be present on a Windows-based system. Finally, we’ll explore questions to consider when detecting and investigating these intrusions over the network.Īs with several other tools, WMI (wmic.exe) and Scheduled Tasks (schtasks.exe) executables are part of a collection of binaries often referred to as LOLBINS, or Living off the Land Binaries and Scripts. We’ll look at WMI and Scheduled Tasks individually to discuss why, how, and what type of adversaries use them for lateral movement. Attackers use a variety of methods for lateral movement, but this post will focus on those using Windows Management Instrumentation (WMI) and Scheduled Tasks.īoth WMI and Scheduled Tasks play the same role in a lateral movement operation: They provide a means of execution on a remote system over the network. Once an adversary gains access to a victim environment, their natural progression will be to move laterally to other hosts of interest, getting ever closer to the ultimate objectives. If you'd like to learn more about Cobalt Strike 3.0, ask questions directly, or see a live demo-stop by the vendor area at either conference to say hi.Lateral movement is a necessary step early in the attack lifecycle of any successful breach. Strategic Cyber LLC will be at BlackHat and DEF CON this year as well. ![]() I expect Cobalt Strike 3.0 to come out late-2015. To answer questions about this effort I've put together a preview demo of Cobalt Strike 3.0: Cobalt Strike 3.0 is a major effort to re-align Cobalt Strike to its red team operations and adversary simulation use cases. There are rumors that I'm working on a mysterious fork of Cobalt Strike with some big changes. This is a reflection of the need for all security assessments to help customers understand how well their defenses work against real-world targeted attacks. My understanding is that a lot of material that was formally in the Adaptive Red Team Tactics course is finding its way into Adaptive Penetration Testing. The Adaptive Penetration Testing course is the beginner-intermediate course on process and tactics to conduct efficient penetration tests today. This class will make heavy use of Beacon and PowerShell. The focus of this class is data mining, abusing trust relationships in large active directory environments, and stealthy lateral movement. The Adaptive Red Team Tactics course is the advanced red team operations course. I will also be on-site as a "lab assistant" to help out on the last day of both runs of these classes. These classes are a good way to learn 2015's Red Team Tradecraft. The Veris Group classes at BlackHat USA are almost full. You'll want to read the rest of the email. I'm curious to see who reads this far into my emails. Licensed Cobalt Strike users may update using the included update program: To see the full list of changes, consult the release notes file: By popular demand-Malleable C2 now exposes options to use a valid SSL certificate with the HTTPS Beacon. This makes it easy to turn a compromised system into a redirector for your payload handler elsewhere.ĥ. This command sets up a reverse port forward on a compromised system. Cobalt Strike 2.5 adds rportfwd to Beacon. spawnas uses PowerShell to avoid touching disk.Ĥ. This release also gives us spawnas which will spawn a Cobalt Strike session as another user with the credentials you provide. This release adds make_token which generates a token that's designed to pass the credentials you provide. With this in mind, commands to manipulate trusts are important. They rely on Windows to authenticate to the target for you. Beacon's lateral movement options do not accept credential material. This listener pairs *very* well with the above lateral movement options.ģ. This listener also comes with a proprietary stager to deliver the SMB Beacon over a named pipe. This listener is designed for use with Beacon's features (e.g., bypassuac, psexec, etc.). This option replaces windows/beacon_smb/reverse_tcp. This release adds a windows/beacon_smb/bind_pipe listener to Cobalt Strike. The psexec command generates a service executable and delivers it to the target.Ģ. These commands use a PowerShell one-liner to inject a payload stager into memory. Use the psexec_psh, winrm, and wmi commands to deliver a Cobalt Strike listener to a target. Beacon now has built-in automation for lateral movement. Trust Relationships and Lateral Movement are the theme of this release.
