Cloudnet virus
Cloudnet virus is a piece of malicious software designed to change system settings and redirect users to dangerous sites

Cloudnet virus is a type of malware that belongs to the Trojan[1] category. Created by Epic Net Inc., it was bugging users since early 2017, and multiple anti-virus engines are still reporting infections all over the world. The threat is usually injected via the dropper malware already present on the system or is downloaded by users from malicious websites. Once installed, Cloudnet virus compromises system security by performing a variety of changes to it. It connects to a remote server controlled by hackers who can remotely send and receive information, which puts sensitive data at risk. The virus runs Cloudnet.exe process in the background, which is located in a subfolder of the user's profile folder, allowing it to perform its activities. Additionally, because the Cloudnet virus is usually transferred with the help of other malicious applications, the possibility of the system being infected with such hazards as crypto-miners, backdoors, keyloggers, and similar threats is quite high.

  • Win32/Glupteba.BC trojan, etc.
Activities Connects to various IPs and URLs, collects and sends out data, compromises system security
Main dangers Personal data theft, additional malware infection
Infiltration Downloaded from malicious websites, installed by other malware
Elimination Use reputable security software to scan your device in Safe Mode
Recovery Use Reimage to restore normal system functions and repair damage done

Because the malware can compromise system security, experts[2] advise not to delay Cloudnet virus removal. However, the process might be a little complicated, as Trojans are sometimes difficult to detect and remove due to persistence techniques used. Therefore, it is highly recommended entering the safe environment in Windows (Safe Mode) and performing a full scan with anti-virus software.

Once the malicious payload is executed, Cloudnet virus backdoor performs the following tasks:

  • Creates a new path %Application Data%\EpicNet Inc\CloudNet\;
  • Creates an executable %Application Data%\EpicNet Inc\CloudNet\cloudnet.exe;
  • Creates mutex to ensure one copy of executable is running;
  • Adds and modifies Windows Registry to ensure persistence;
  • Creates a proxy connection;
  • Downloads and executes arbitrary files.

Once system modifications are complete, Cloudnet virus can start its malicious activities. First of all, it sends out a variety of information (OS version, processor name, memory information, malware version, etc.) to a C2[3] server starts redirecting users to dangerous websites and also include users' emails in advertisement campaigns, which can spam the inbox rather quickly.

Because the backdoor can modify proxy settings, some users might have troubles when trying to remove Cloudnet virus. Nevertheless, powerful security software should be able to perform the task in the Safe Mode. Please refer to the bottom section of the blog.

Once Cloudnet virus elimination is complete, you should scan your devices with Reimage – it can repair Windows Registry automatically and recover from system damage in just a few minutes.

Cloudnet trojan
Cloudnet virus is a trojan horse that arrives on the system with the help of other malware present on the system or is downloaded from a malicious site

Be careful when surfing the internet – malicious scripts can install malware on your system

Malicious software developers have always been looking for new ways to infect as many users as possible. While the most primitive methods range from hosting malicious links on websites, some sophisticated techniques rely on exploit kits that abuse software vulnerabilities.

While no method would keep you out of trouble 100%, there are several methods that you could decrease the chance of trojan infection by a lot. Some most basic security measures (which most users still fail to implement) include a running anti-malware software and timely system updates. However, probably the most important thing is to be attentive while browsing the internet.

Security software cannot and will not protect you from ALL viruses, as new threats are being developed every day, and databases of AV engines and not immediately updated. Therefore, do not browse questionable sites (like torrent, porn, gambling), do not download pirated software, and use ad-block for your own safety.

Remove Cloudnet virus and prevent further system compromise

If Cloudnet backdoor entered your machine with the help of other malware, your device might be infected with multiple threats. Different malware serves different purposes, however, they do not bring anything beneficial for the victim and can even result in loss of funds, personal files or even identity theft. Therefore, computer security should not be treated lightly. Talking about this particular threat, you can open Task manager and check if Cloudnet.exe is running.

Remove Cloudnet virus with the help of security software. Beware that not all anti-virus applications may recognize the threat, so you might have to use a different program to eliminate malware completely. Besides, if your machine is affected by other malicious threats, AV software should be able getting rid of it all in one scan.

Once Cloudnet virus removal is completed, use Reimage for system repair. It will restore Windows registry and delete unnecessary processes malware created.
