Analysis Summary
DCRat – a Russian backdoor, was initially introduced in 2018, but rebuilt and relaunched a year later. The DCRat backdoor appears to be the product of a single threat actor who goes online with the pseudonyms of “boldenis44,” “crystalcoder,” and Кодер (“Coder”).
DCRat is one of the cheapest commercial RATs. For a two-month membership, the price starts at 500 RUB (less than 5 GBP/US$6), and it periodically drops even cheaper during special offers. This is written in .NET and features a modular structure, allowing affiliates to create their own plugins using DCRat Studio, a dedicated integrated development environment (IDE).
The malware’s modular architecture allows it to be extended for a variety of nefarious objectives, including surveillance, reconnaissance, data theft, DDoS attacks, and arbitrary code execution.
The DCRat consists of three parts:
- A stealer/client executable
- The command-and-control (C2) endpoint/ interface is a single PHP page
- An administrator tool
The malware is still in development, the author announces any news and updates through a dedicated Telegram channel with about 3k users updated with any news and changes.
