The Dtrack RAT has been attributed to the Lazarus cluster, which is alleged to be fairly active in terms of malware development. This RAT has been targeting Indian monetary establishments and analysis centers with tools the same as those employed in the 2013 Seoul campaigns. one in all the recent tools believed to originate from the computers of the Lazarus Advanced Persistent Threat cluster is Dtrack RAT, a foreign Access Trojan that permits its operators to require virtually complete management over infected computers. It’s believed that the Dtrack RAT is said to be an ATM track, a chunk of ATM malware that was found on the computers of Indian banks in 2018. each tool square measure developed and employed by the Lazarus APT cluster, and it’s possible that the ATMDtrack maybe a stripped version of the Dtrack RAT.
The dropper has an encrypted payload embedded as an overlay of a PE file. The overlay statistics, whilst decrypted, contains an additional executable, technique hollowing shellcode, and a listing of predefined executable names. Its decryption ordinarily has been observed to begin between the start() and WinMain() functions. The malicious code is embedded into a binary that could be an innocent executable inclusive of the Visual Studio MFC project. Once the statistics are decrypted, the process hollowing code starts. It takes the name of the technique to be hollowed as an argument.
When the Dtrack RAT is initialized, it’ll connect with the pre-configured address used for a Command & management server forthwith. The RAT checks for brand spanking new commands at a particular interval, and executes all unfinished tasks forthwith. The wrongdoer will assemble the interval between command checks, and that they conjointly can:
Upload or download documents to the compromised pc and launch them.
Grant startup persistence to documents they choose.
Copy the contents of a folder, partition, or hard drive to their control server.
Update the Dtrack RAT or cast off it.
The range of victims tormented by the Dtrack RAT continues to be very low, and cybersecurity professionals have now not been able to perceive a unique safety hole that the Lazarus hackers may have used to deliver the threatening program. It is in all likelihood that they try and take advantage of vulnerable services and software programs, unpatched running systems, or poorly secured networks.
Defending against Dtrack
As the criminals are looking to benefit partial manage over the community for spying via this campaign, security professionals recommend businesses to:
Enhance community and password policies
Use visitors monitoring software and antivirus solutions
