TTP Tuesday: APT29 - RNC Hack

3rd party mischief

Theme Overview

This week we are releasing our last APT29 themed chain based on the RNC hack in 2021. ESET has identified and attributed the attack to APT29. Like our previous case studies, not much information about this attack has been released.

Utilize me: Third party tools

This week's kill chain focused on APT29’s utilization of 3rd party software. APT29 used AdFind, an Active Directory query tool, in order to collect information about compromised networks. They’ve also extensively utilized Dropbox as a means upload results of reconnaissance. To model these behaviors, we created our latest chain, ExBox. This chain executes AdFind to collect information, compresses these results, and exfiltrates these results to Dropbox.
