What is Ghost?

Cyber criminals use the Ghost ransomware-type virus to infect systems and encrypt data, thereby making it unusable until the ransom demands are met. Ghost was discovered by MalwareHunterTeam. Once a computer is infected, this virus renames all encrypted files by adding the ".Ghost" extension. For example, "1.jpg" becomes "1.jpg.Ghost", and so on. Ghost is designed to display a ransom note in a pop-up window.

According to the cyber criminals behind the Ghost virus, they have encrypted all files and demand payment of 0.08116 of Bitcoin (currently equivalent to ~$425) if victims wish to retrieve their files via a decryption key (or tool). They also urge victims to contact them via an email address and ID provided. Ghost developers provide a Gmail email address ( as a means of contact. This is unusual, since cyber criminals generally do not use public email services to make ransom demands as it greatly increases the risk of being caught. Note that ransomware developers often ignore victims even if they are contacted and the ransom demands are met. In this way, people are scammed. It is not known which cryptography algorithm (symmetric or asymmetric) Ghost developers use to encrypt files. In any case, there is no tool capable of cracking Ghost ransomware encryption free of charge. Generally, if a system is infected by a virus of this type, the best (free) solution is to restore files using an existing backup.

Cyber criminals use many different ransomware viruses. Other examples of similar infections are BlackHat, .pptx, and DataWait (and many more). Most ransomware-type viruses of this type lock/encrypt files and make ransom demands. Size of ransom and cryptography algorithm used to encrypt the files are usually the only differences. A unique decryption key is generated for each victim and stored on a remote server controlled by cyber criminals. Ransomware viruses cannot easily be cracked, and thus decryption without involvement of cyber criminals is generally impossible. To prevent data loss, we recommend that you maintain regular backups and store them on a remote server or unplugged device.

How did ransomware infect my computer?

It is not clear exactly how Ghost developers proliferate their ransomware, however, some common methods include spam email campaigns, untrustworthy third party software download sources, fake software updating tools and trojans. Cyber criminals employ spam campaigns to spread viruses through malicious email attachments (or links). They send emails containing malicious Microsoft Office documents, archive files, PDF files, executable files hoping that people will open them. Once opened, these attachments (or links) download and install viruses. Untrustworthy third party software download sources such as peer-to-peer networks (torrent clients, eMule, etc.), free file hosting, freeware download websites and other similar sources are used by criminals to trick people into installing viruses. They achieve this by presenting malicious executables (.exe) or other files as legitimate. In some cases, they use fake software updaters - these tools are used to do download and install viruses rather than the promised updates or to exploit outdated software bugs and flaws.

Threat Summary:
NameGhost 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 Ghost virus our malware researchers recommend scanning your computer with Spyhunter.

How to protect yourself from ransomware infections?

To prevent computer infection by ransomware-type viruses, browse the Internet, and install/download and update software carefully. Do not open email attachments (or links) received from unknown, untrustworthy or suspicious addresses. Avoid opening files that are attached to irrelevant emails. When updating software, use implemented functions or tools provided by official developers only. Do not use third party tools. Never download software from untrustworthy/unofficial websites or using third party downloaders. It is possible that these third party download or installation set-ups will contain rogue applications that might cause high-risk computer infections. Having a reputable anti-spyware or anti-virus software installed is also paramount. These tools can prevent computers from being harmed by various infections. If your computer is already infected with Ghost, 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 Ghost 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 Ghost 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 Ghost 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 Ghost, 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 Ghost 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:
