Echida Stealer is a new data collection and remote command-receiving malware written in C# programming language. Despite limited sample data, it offers data collection capabilities and remote control features. Targeted for various purposes, its unique advantage is remote command reception. However, ethical and legal concerns surround its use, and ongoing development and testing are needed for competitiveness. There are limited samples, and samples are pointed out for testing at this time. The first sample was brought to discussion by Viriback on September 4th, 2023.

The main capabilities of malware consist of receiving and running a command from the server, generating unique hardware identifiers for every victim, mining cryptocurrency on the victim’s device, and adding an infected computer to the botnet that might be used for various purposes, such as DDoS attacks.

Analyst Note

Beta version of the panel does not seem to work properly and has lots of typos at this point. For example, panel title is “Danshboard” and few endpoints of the server is available as open directory.

Analyst Note (From Command and Control Communication Section)

Although commands and capabilities of the malware are limited at the time, with remote update and plugin installation option can be used for migration to more stabilized and foolproof infrastructure. The malware panel has various options such as steal logs and crypto mining. These features not implemented on the malware yet, but actors does not require whole new process of infection.

Conclusion

In conclusion, Echida Stealer, though not yet available in the market, enters the domain of data-stealing software, particularly relevant to botnet operations. While its capabilities may not be entirely unique, they highlight the ongoing concerns surrounding such technology, especially within the context of botnets.

As this software undergoes development, it is imperative to recognize that responsible technology use should be at the forefront. Echida Stealer’s potential for data collection and remote control is particularly interesting to those involved in botnet activities, underscoring the need for heightened vigilance.

In a world where botnets and cyberattacks pose significant threats to digital privacy and security, the emergence of software like Echida Stealer reinforces the importance of comprehensive cybersecurity strategies. Further development and testing should be carried out with a focus on responsible standards within the evolving landscape of botnet-related activities.
