Further analysis reveals that the campaign is mostly using the spear-phishing emails to deliver the malware through the weaponized Microsoft Office document attachment.
There are different versions of the sample has been used for this campaign between 2009 to 2017, and the latest version of the malware used until 2017.
APT campaigns’ command and control server deployed in the cloud storage at mydrive.ch. “For every victim, the operators created a new account there and uploaded additional malware modules and a configuration file with commands to execute it.”
It performs the following actions once it connected to the C2 server:
- downloaded the command file to the working directory;
- uploaded files collected and prepared by additional malicious modules
- downloaded additional malware modules
According to Kaspersky research, The glue30.dll malware module provides keylogging functionality. The updater.mod module uses the Win API function SetWindowsHookExW to install hooks for the keyboard and to inject glue30.dll into processes that get keyboard input. After that, glue30.dll loads and begins intercepting input in the context of each hooked process.
DarkUniverse campaign collecting various sensitive information including Email conversations, Files from specific directories, Screenshots, information from the Windows registry, Sends a file to the C2, Credentials from Outlook Express, Outlook, Internet Explorer, Windows Mail and more.
