Rogue ransomware removal instructions

What is Rogue ransomware?

Based on Hidden Tear, Rogue ransomware was discovered by GrujaRS. As a rule, software of this type encrypts files (makes them inaccessible), renames them and creates and/or display a ransom note (or multiple notes). Rogue renames encrypted files by appending the ".rogue" extension to their filenames, for example, it renames "1.jpg" to "1.jpg.rogue", "2.jpg" to "2.jpg.rogue", and so on. Also, it changes victim's desktop wallpaper to a ransom note and creates another note, a text file named "READ_IT.txt".

Both ransom notes ("READ_IT.txt" file and desktop wallpaper) have four website addresses in them. Those addresses open pages that contain instructions on how to pay a ransom. As explained in them, victims have to send 0.05 of Bitcoin to the provided Bitcoin address (wallet), click the "payment" and then "Payment Received" buttons. This should start downloading a decryption tool which supposed to decrypt files encrypted by Rogue ransomware. However, it is common that victims who pay cyber criminals get scammed. They do not receive any decryption tool even after a payment. Therefore, ransomware developers should bot be trusted. Unluckily, most ransomware-type programs make sure that victims could not decrypt encrypted files without tools that can be purchased only from cyber criminals who designed ransomware. In most cases the only way to recover files without losing any money and risking to get scammed is to restore them from a backup. Also, it is recommended to uninstall ransomware from the infected operating as soon as possible because that prevents it from causing any possible further encryptions. Although, encrypted files remain inaccessible even after its uninstallation.

There are many ransomware-type programs that are similar to Rogue. A couple of examples are Serpom, NEPHILIM and NEMTY REVENUE 3.1. In most cases they are designed to lock files by encrypting them and create (and/or display) a ransom note or multiple notes. The main and most common differences are price of decryption tool and/or key and cryptographic algorithm (symmetric or asymmetric) that ransomware users to encrypt files. Unfortunately, cyber criminals behind ransomware often are the only ones who can provide tools that can decrypt files encrypted by their ransomware. In other words, it impossible to decrypt files for free unless ransomware is not finished (has some bugs, flaws etc.). That is why it is important to always have data backed up and keep it stored on some remote server (like Cloud) or unplugged storage device.

How did ransomware infect my computer?

Most cyber criminals attempt to spread ransomware by using spam campaigns, fake software updaters, untrustworthy download channels, unofficial software activation tools and Trojans. It is very common that cyber criminals seek to trick users into installing malware by sending emails that include malicious attachments or website links that are designed to download malicious files. Usually they attach some malicious Microsoft Office document, archive file (like ZIP, RAR), PDF document, JavaScript or executable file (like .exe) and hope that recipients will open (execute it). Unofficial (fake) updating tools infect systems by installing malicious programs instead of updating installed ones, or by exploiting bugs, flaws of some outdated software. Examples of untrustworthy software download channels are unofficial pages, Peer-to-Peer networks (e.g., torrent clients, eMule), free file hosting, freeware download sites and other channels of this kind. Cyber criminals often use them as tools to host, upload malicious files. Typically, they are disguised as legitimate, regular. When users download and open them, they cause installation of some high-risk malware. It is worthwhile to mention that third party installers can be used to distribute malware too. Software 'cracking' tools (unofficial activators) supposed to activate paid software for free. Nevertheless, instead of doing that they often install malicious software. Trojans are programs that can be designed to spread other malware. Simply said, if a malicious program of this type is installed on the operating system, then may install other software of this kind.

How to protect yourself from ransomware infections?

Irrelevant emails that contain some attachment (and/or website link), are received from unknown and/or suspicious address should not be trusted. It is common that such emails are being sent by cyber criminals who attempt to proliferate malware. All installed software must be updated and activated with implemented functions or tools that are designed by official software developers. None of the third party updaters or activation tools should be trusted. Besides, it is not legal to bypass activation of licensed software with various unofficial, 'cracking' tools. Furthermore, it is important to download software from trustworthy, official websites, and via direct links. Tools, channels liket third party downloaders, installers, questionable pages and other similar sources are mentioned in the previous paragraph can be used to distribute unwanted, malicious software. And finally, it is recommended to regularly scan a computer for threats with a reputable anti-spyware or antivirus software, detected threats should be removed as soon as possible. If your computer is already infected with Rogue, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Rogue ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Rogue are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by Rogue, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Rogue ransomware.

Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites, and Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
