DarkHydrus Abuses Google Drive To Inject RogueRobin Trojan

DarkHydrus - a malicious hackers group recognized as an advanced persistent threat (APT) is back and this time is not only using Windows vulnerabilities but is also abusing google drive as an alternative communication channel to spread RogueRobin Trojan horse and perform other malicious activities, as well as avoid detection by antivirus programs.

The DarkHydrus trojan virus was first discovered in July last year when group carried out its illegitimate activities and attacks against government organizations and educational institutions in the Middle East.

Recently, the group has launched a yet another attack, striking against the political targets in the Middle East.

This time, the DarkHydrus APT is found using Google Drive to communicate with backdoor Trojan called as RogueRobin which is using weaponized Microsoft Excel documents to compromise victim’s system.

These Excel documents are written in Arabic and contain embedded VBA macros which will trigger the malicious commands if the file is opened.

The macro in the malicious document downloads a .TXT file to a temporary directory and then the legitimate 'regsvr32.exe' application is used to run the text file.

According to researches, the text file hides a Windows Script Component (.SCT) file that delivers a version of the RogueRobin Trojan on the targeted system.

The malicious program is written in a C# programming language and the trojan contains the anti-debug code which makes it even more complicated.

The samples of the RogueRobin trojan implement additional functionality and include Google Drive API as a secondary method for sending the malicious commands.

This new feature allows the remote attackers to use Google Drive as an alternative C&C server and makes it even more difficult to detect the malicious traffic.

The RogueRobin Trojan is used to accumulate and send system information including hostnames, to C&C server through a DNS tunnel.

However, if the DNS tunnel is not available, the trojan will contain the instructions under the name "x mode" to use Google Drive as an alternative file server which acts as a backup if the main C&C server communication route fails.

The ‘x_mode’ command is disabled by default but when it is enabled through the DNS tunneling channel which is the main communication with the C&C server.

Once activated, it allows RogueRobin to receive a unique identifier, which is also known as a list of settings stored in the variables set and these values allows to exchange information like URL for downloading, updating files, uploading, and the authentication details through Google Drive.

As it is a malicious program and the longer it stays on a computer, the more it weakens the firewall of the system and making way for other malware.

However, since you are on this page, you are already a step ahead and as the article advances, you will come to know how to remove DarkHydrus Malware before it causes more harm to your PC.
