Trojan:Java/Agent!MSR is a type of malware that exploits certain vulnerabilities on the computer to execute a malicious Java script file. Once inside and active on the computer, this threat can establish a remote connection and perform data-gathering functions on the computer. It can spy on computer details like the installed operating system, network details, security settings, and more. Trojan:Java/Agent!MSR can perform other malicious actions as commanded by the remote attacker as long as it is persistently operating and the communication towards the remote server is active. Therefore, computer users must act at once to remove this malware by thoroughly scanning the computer with an effective antivirus program.
How does it infect the computer?
Trojan:Java/Agent!MSR uses stealthy techniques to get inside the computer through a malicious Java script file. The actors behind this threat are said to be utilizing a variety of distribution techniques, and a wide array of resources via the internet. Hence, the most common ones include “malvertising” (malicious advertising), where the file is disguised as a software update or necessary tools that users must download in order to watch a video, listen to music, or play an online game.
Software piracy is also observed as a channel that attackers are using in deploying Trojan:Java/Agent!MSR. In-demand freeware or commercial software is being modified to include the malware code so that it installs alongside the application.
How does this malware operate?
Please do note that Trojan:Java/Agent!MSR is a heuristic detection for a threat that uses Java script file in order to infect a computer. Its operation normally depends on the design of the variant that infects the system. However, it is commonly associated with data-stealing actions once they are operational. Trojan:Java/Agent!MSR can gather information like computer settings, Windows version, networking setup, installed programs, and security settings.
The existence of Trojan:Java/Agent!MSR on the computer is a real threat to the user’s privacy and security. Aside from data gathering, it can elevate its payload to act as a backdoor. When that happens, the remote attacker may gain full access to the compromised system and do any of the following malicious actions:
- Steal sensitive information like usernames and passwords.
- Drop and execute another threat.
- Deactivate security programs and alter the firewall settings.
- Infect the internet browser program to execute redirects.
