Microsoft previously used ‘Solorigate’ as the primary designation for the actor, but moving forward, we want to place appropriate focus on the actors behind the sophisticated attacks, rather than one of the examples of malware used by the actors. UPDATE: Microsoft continues to work with partners and customers to expand our knowledge of the threat actor behind the nation-state cyberattacks that compromised the supply chain of SolarWinds and impacted multiple other organizations.

Acknowledgementīig thanks to rsmudge for his cintinous support and responsiveness to questions. Yes, with a star, a retweet, or by inviting me to your Red Team after I graduate from uni. Yes, on Twitter or by email Can I/We help you? Also, if you are interested in having aggressor scripts for these BOF, please lemme know! Can I/We reach you? If you need assistant, please do not hesistate to contact me. However, it goes without saying that you should modify and test the scripts before you run them in your engagements. Before pushing these scripts to GIT, they were tested on an Enterprise environment where a network MDR service is provided, and no alerts were trigged. I am not a seasoned developer yet, so use with care. What I did was minor modifications and porting it to BOF. However, the WMI lateral movement parts are mainly done by others. The DCOM lateral movement took sometime to figure out, and I did not find it done in other projects/repos. I have a curiosity that copy/pasting powershell commands is killing. I ported these techniques to BOF in order to learn more about Windows, CobaltStrike, and lateral movement. However, this method will cause the prompt "a program is trying to access email address information" each time an email is received, so I recommend to use it ONLY IF you know that this feature is disabled (it is quite common to see it disabled in Enterprises, but an additional OPSEC never hurts). If you do so, the application will only trigger if the body of an email contains "it can also be a sentence!". You can also specify the body option like the followingīofnet_execute On_Demand_C2_BOF.OnDemandC2Class body "it can also be a sentence!" *This is a COVLD-19 with a small L to ensure uniqueness The email will directly get redirected to Deleted Items and beacon will be calling home again! NET project (cheers to CCob for the brilliant work!) and follow CCob's guide here to load the the dll into the beaconĢ ) Execute it using the following: bofnet_execute On_Demand_C2_BOF.OnDemandC2Class subject COVlD-19*ģ ) Now, to have a callback from your beacon, you can send an email like As an extra, the email with the given word will be deleted before the user get notified about it. When you are done you can run the BOF again and the beacon will sleep until you send another email. When the beacon calls home, it will call home with whatever sleep time configured in the malleable profile. This way your beacon will only call home ONLY when you want it to call home. The beacon will enter a sleep state until an email with a given word (in subject or body) is provided. This is an implementation of an on-demand C2 using dotnet BOF. Most of the heavy lifting was done by wumb0in 4 ) On-demand C2 This one uses WMI events for lateral movement. 3 ) WMI Lateral Movement - Event Subscription This method uses the class Win32_Process. Similar concepts to the previous one, but an interesting learning experince. 2 ) WMI Lateral Movement - Win32_Process Create A short article can be about using COM objects in C can be found here. To use the current user, just leave the domain, username, and password empty. 1 ) DCOM Lateral MovementĪ quick PoC that uses DCOM (ShellWindows) via beacon object files for lateral movement.You can either specify credentials or use the current user.
