PyVil Trojan – Virus Infection Methods
The PyVil Trojan is a Python-based malware that is being orchestrated against computer victims by a very experienced hacking group. The detected campaign appears to be focused on financial groups and companies. The aim of the hackers is not only to deploy the Trojan but also to automatically hijack as much information from the victims as possible.
What we know from the conducted analysis is that this Trojan is orchestrated by the Evilnum hacking group which has been known to us since 2018. The attacks that utilize this virus are mainly against financial institutions and organizations which are primarily located in Europe. One of the important characteristics of this malware is that it is written in the Python programming language which makes it cross-platform — it can run on practically all modern desktop and mobile operating systems.
The main distribution mechanism appears to be the use of phishing email messages. The criminals will construct messages that appear as important notifications or contacts and send them out in bulk to the intended recipients. Upon receiving the files the users will find that there will be an attached ZIP archive file or LNK files that appear as PDF documents. When they are launched on the local machines the infection will be started.
PyVil Trojan – Virus Capabilities
Upon execution, the PyVil Trojan will start its malicious sequence automatically. The virus samples show that it is capable of hiding from detection by looking for any installed security programs: firewalls, anti-virus engines, intrusion detection systems and other applications. This shows that the virus is fully capable of having full process control — it can hookup to running processes and monitor their operations, as well as stopping them. The main virus engine can subsequently create its own threads with system administrator privileges thereby reserving its own memory space and launching even more complex actions.
The Trojan function will be run after right the security bypass has been done. The local agent will connect to a hacker-controlled server and allow the remote attackers to completely take over control of the machines. Furthermore, they can spy on the victims in real-time and steal their files.
The detected instances have been found to install themselves as persistent threats. This means that the virus will start itself when the computer is powered on and the setup commands may disable access to the recovery boot options. As a result, most manual user recovery guides will not work correctly.
This PyVil Trojan can be used to install other malware as well, a popular option is the file encrypting ransomware. This is a popular category of computer viruses that are designed to encrypt target users’ data with a very strong cipher. All processed files will no longer be accessible to the users and they will be blackmailed to pay a ransom decryption fee.
Given the fact that the criminal group is very experienced other functionality can be added in future samples.
