Trojan.Volgmer

Researchers in the cybersecurity world are well familiar with the Trojan.Volgmer because it has been actively used since at least 2013. Unfortunately, malicious trojans have a bad habit of resurrecting when cybercriminals need them. In 2017, for example, this malware was used in the Hidden Cobra attacks, which are linked to North Korean cyberwarfare. When will this malware strike next? When will it be used to open backdoors via which cybercriminals could invade systems? We cannot predict that, but if one thing is for sure, it is that it is never too late to implement security blockades just in case. While this trojan is most likely to be used by state actors in attacks targeted at governments, regular users cannot sit with their hands folded tight. Everyone needs to take action. In this report, we summarize what is already known about this malicious threat, which should help you better understand how it works. We also add instructions on how to remove Trojan.Volgmer if it is found on a Windows operating system.

It is important to note that Trojan.Volgmer is a backdoor trojan, which means that it used to enable remote access, using which, cybercriminals can take over the device, system, or network. The trojan is installed by a malicious dropper file (.exe) that could be dropped in various ways. A spam email attachment could hide it. It also could be hidden in removable drives, sent via a bundled downloader, or dropped using an unpatched vulnerability, which cybercriminals could exploit silently. The trojan is unlikely to act on its own. For example, during the Hidden Cobra attacks, Trojan.Volgmer was paired with FallChill, a remote administration tool (RAT). Therefore, if you happen to discover this trojan, it is a must to inspect the entire operating system for other threats that could exist and require removal also. If you purchase a second-hand computer or if your own computer has been neglected for years, trojans, RATs and other threats could be discovered. Even if attackers are not using this malware at the moment, you must delete it.

If used actively, Trojan.Volgmer can be very intrusive. This malware can read files and send them to the attackers’ servers, execute shell commands, download and delete files, update IP addresses, download IP addresses, and open ports. Essentially, this malware can retrieve highly sensitive information, mess with all files, and even delete malware once it completes the tasks to keep malicious activity under wraps. This trojan can give cybercriminals immense power to do a lot of damage. And if it is paired with an even more intrusive infection, it could be used to take over systems, steal sensitive data, drop other threats, and so on. Ultimately, when cybercriminals have goals, nothing can stop them from achieving them, and such threats as Trojan.Volgmer can help them immensely. It is most important that government agencies, large companies, and other entities that state-backed cybercriminals could target take action to secure their systems and educate employees about potential dangers. If all security measures are implemented, it is harder – if not impossible – for cybercriminals to perform successful attacks.

If you are dealing with trojans, RATs, and other kinds of malware, there really is no reason to mess around with manual removal. Leave that to potentially unwanted programs, adware, hijackers, and other low-level threats. When it comes to critically dangerous malware, you need the help of anti-malware software. Not only can it automatically detect and delete Trojan.Volgmer and other threats but also secure your system in the future. It goes without saying that if you do not secure your system, new threats could try to invade it again. Even Trojan.Volgmer itself could find its way back. If you discover trojans and RATs, you need to contact your IT support team immediately because they are the ones who are trained to deal with attacks. If you are an individual user, you need to secure your system and think about what kinds of personal data could have been leaked by the trojan. For example, if you are a small business owner, perhaps the attackers could have stolen files with customer and order data? Whatever happens, you need to react immediately.
