DarkHydrus Hacking group Uses Microsoft Excel To Inject RogueRobin Malware

RogueRobin Malware is an infamous threat developed by APT hacking group DarkHydrus. The new malicious campaign attributed to this group abuse Google Drive and Microsoft Excel via C2 servers for worldwide attacks.

According to cybersecurity reports, the targeted attacks involved sending macro-enabled Excel documents (VBA code) and .xlsm files via phishing emails in the Arabic language.

DarkHydrus - a malicious hackers group is targetting middle east countries. Macros download a .txt file document and regsvr32.exe application then a c# file drops down onto the victims' computer.

Once the file executes, it fetches a payload dubbed as RogueRobin malware which is a fully featured backdoor providing varieties of functionalities to the threat authors.

It allows the operators of DarkHydrus to execute PowerShell scripts such that it takes advantage of PowerShell features and add functionality by generating new scripts.

Before carrying out any functionality, the payload checks whether it is executing in a sandbox. If the payload is not running in a sandbox, then it tries installing itself persistently into the system.

The payload interacts with C2 server and then inject and communicate with DarkHydrus’ Malware. RogueRobin malware uses Google Drive as C2 Channel which we are going to describe later in this article.

What is RogueRobin Malware?

It is a high-risk trojan which distributes via email spam campaigns and delivers malicious attachments like Microsoft Excel documents into the victims' computer.

After the successful infiltration, RogueRobin connects to the remote server, downloads several files and run the number of commands from that file. Cyber criminals or malware attackers basically gain remote access to the system and perform various actions inside it without user permission.

The malware uses Google Drive as a second method to send malicious instructions via DNS tunneling channel and activates x_mode command. Once the values are assigned to every variable of the command, RogueRobin uploads file to Google Drive.

The malware continuously uses DNS tunneling to communicate on C2 servers. It also repeatedly checks for debuggers everytime it does a DNS query. If a debugger is identified, the query generates a hex-coded subdomain (676f6f646c75636b.gogle[.]co) which means 'goodluck.'
