The Gamaredon group has been active since at least 2013. Contrary to other APT groups, the Gamaredon group seems to make no effort in trying to stay under the radar. Typical Gamaredon compromise chain . While most of the recent publications have focused on the spearphishing emails together with the downloaders they contain, this blogpost focuses on the post-compromise tools deployed on these systems. Office macro injection module – CodeBuilder . We analyzed different variants of malicious modules used by the Gamaredon group to inject malicious macros or remote templates into documents already present on the compromised system. It then scans for documents with valid Word or Excel file extensions on all drives connected to the system. The most prevalent tools downloaded and installed on compromised machines can be broadly grouped into two different categories: downloaders and backdoors. Backdoors – file stealers . While some variations exist in functionalities, the main purpose of these modules is to enumerate all documents on a compromised system and upload them to the C&amp;C server. The behavior of this module is quite straightforward: it scans the system for new Microsoft Office documents, both on local and removable drives, and uploads them to the C&amp;C server. Quality of execution . We were able to collect numerous different samples of malicious scripts, executables and documents used by the Gamaredon group throughout their campaigns. Conclusion . Despite the simplicity of most of their tools, the Gamaredon group also is capable of deploying some novelty, such as their Outlook VBA module
