Outsider ransomware removal instructions

What is Outsider?

Outsider is classified as a ransomware-type computer infection designed make files unusable by encryption. This virus was discovered by GrujaRS, and like most programs of this type, renames each encrypted file by adding a specific extension - in this case, ".protected". For example, "1.jpg" becomes "1.jpg.protected". Outsider also generates a "HOW_TO_RESTORE_FILES.txt" ransom message and places it in every folder that contains locked files.

According to Outsider's developers (designers of this virus), all files have been encrypted using the RSA encryption algorithm (1024 bit). The cyber criminals state that, by encrypting files, they ensure that they are safe from any other third parties. This, of course, also prevents access by their victims. To decrypt (unlock) files, victims are encouraged to contact Outsider's developers via an email address (secureserver@memeware.net) and provide their assigned IDs. The cost (effectively the ransom amount) of a decryption tool is $900 and must be paid in Bitcoins. Victims are urged not to use decryption tools other than Outsider's, since this will apparently result in permanent data loss. They offer free decryption of one file. This is common to many ransomware developers - a gesture that they can be trusted, are capable of decryption, and have tools available for this function. In fact, cyber criminals cannot be trusted. They often simply ignore victims, whether or not ransom demands are met. Unfortunately, most cyber criminals generate unique decryption keys and store them on remote servers that are controlled only by them. This gives them the advantage, since only they can provide victims with decryption tools or keys. There are no tools capable of decrypting files locked by Outsider free of charge. The only free solution is to use an existing backup and restore everything from there.

Many cyber criminals attempt to infect computers with ransomware-type viruses. Some examples of other infections of this type are Santa, .shadow, and Bkpx. Typically, these are have identical functions: they affect computers by encrypting files, making them unusable, and thus giving cyber criminals the ability to blackmail victims by making ransom demands. Generally, the main differences between these infections are ransom size and the cryptography algorithm used to encrypt data stored on computers. It is generally impossible to decrypt the files without contacting cyber criminals (not recommended), unless the virus is not fully developed or has bugs/flaws. Therefore, maintain regular backups and store them on remote servers or unplugged storage devices.

How did ransomware infect my computer?

It is not known how Outsider proliferates this virus, however, cyber criminals usually employ spam email campaigns, trojans, untrustworthy software download sources, and fake software updaters. Spam campaigns are used to deliver malicious attachments that, once opened, download and install computer infections. These attachments could be PDF, archive files, executables, Microsoft Office documents, and so on. Trojans are malicious programs that cause chain infections (they proliferate other viruses). Various untrustworthy software download sources (such as freeware download, free file hosting websites, peer-to-peer networks, and so on) are often used to present malicious executables as legitimate software. In this way, users are tricked into downloading and installing viruses rather than the chosen software. Fake software updaters infect operating systems by exploiting outdated software bugs/flaws or by downloading and installing infections rather than the updates.

Threat Summary:
NameOutsider virus
Threat TypeRansomware, Crypto Virus, Files locker
SymptomsCan't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.
Distribution methodsInfected email attachments (macros), torrent websites, malicious ads.
DamageAll files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.

To eliminate Outsider virus our malware researchers recommend scanning your computer with Spyhunter.

How to protect yourself from ransomware infections?

Browse the web, download, install, and update software attentively. Ignore emails that include various attachments (or links) received from unknown/suspicious addresses. If the email is irrelevant or you are not sure if it is safe to open an attachment, ignore it. Do not download (or install) software using third party downloaders (or installers). These are often monetized by promoting deceptive, rogue applications. The best way to download software is use official and trustworthy sources and using direct links. Update your software correctly, legitimately: use tools or implemented functions that are provided by official software developers. This does not include third party updaters. Have reputable anti-virus/anti-spyware software installed and enabled at all times. These tools are capable of detecting and stopping viruses before they can do any damage. If your computer is already infected with Outsider, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

4. In the opened window, click "Next".

restore system files and settings

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Outsider ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

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 Outsider 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 Outsider 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 Outsider, 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 Outsider 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 as well as 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.

HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
