This post has been created to help you remove the newly emerged CA$HOUT ransom virus and restore files enciphered by this infection on your PC.

A ransomware computer virus, carrying the ironical name CA$HOUT has been detected by security researchers. CA$HOUT’s end goal is to get the victim of the infected computer to pay $100 in order to get his files restored back to their original state and become accessible once more. The virus uses encryption mode to make the files not openable to reach this end goal. Read this article if you have become a victim of the CA$HOUT ransom virus.

How Is CA$HOUT Ransomware Spread

CA$HOUT ransomware virus is programmed to infect while remaining undetected. It can be prevented, however. Ransomware threats, like this often tend to use e-mail spam messages to spread. This is the convincing e-mail from PayPal that there is suspicious activity on your e-mail account, the e-mail from your bank, from eBay or any other institutions. Usually, those e-mails have malicious objects embedded in them. These objects are either malicious files or malicious web links. Sometimes the cyber-criminals use archives to mask the malicious files, so that they cannot be detected, for example:

Other methods by which CA$HOUT ransomware virus may have infected your computer system are to spread the virus via torrent websites or websites that are suspicious. The malware may come as fake updates, activation programs, like cracks and other such software. It can also automatically infect your computer if you have other, malware on it, like a Trojan Horse, for example.

CA$HOUT Ransomware – More Information

As soon as you become infected by CA$HOUT ransomware, the virus may connect to a distribution server and download the malicious files of the virus. The payload of CA$HOUT ransomware consists of the following files:

• Info.exe
• Temp.exe

These files may be located anywhere on the %SystemDrive% of your computer. One of them is the file which encrypts your important data and the other is the lockscreen of CA$HOUT Ransomware which aims to convince you into paying $100. The lockscreen looks like the following:

In addition to this, CA$HOUT ransomware may also create multiple Windows registry entries on your computer. They are basically value strings added in sub-keys of the Windows Registry Editor. These sub-keys are usually the following:

→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

These keys are primarily targeted and in them, CA$HOUT may have value strings with data in them that points out to the actual location of the malicious virus file responsible for encrypting your data.

How Does CA$HOUT Encrypt Files

Similar to many other file-encryption viruses, CA$HOUT replaces segments of data from original files with data from the encryption algorithm it uses which is presently unknown. From there, the virus begins to perform multiple different activities that generate a unique decryption key. This key is sent to the cyber-criminals, making them the only ones possible to decode the files directly. However, no matter how dire the situation is, security experts do not advise paying the ones, who are infecting with CA$HOUT ransomware, because:

• You support criminal activity.
• It is no guarantee you will get your files back.
• Texttt

CA$HOUT ransomware may encrypt the files with the following file extensions if it detects them on your computer:

Remove CA$HOUT andyou’re your Data Back

In order to remove CA$HOUT ransomware we advise you to follow the removal instructions below. They are specifically designed to help you delete the files by isolating the virus in Safe Mode. However, tampering with malicious files may be risky if you lack the experience. This is the main reason why experts advise that a ransomware-specific removal scanner should be sought out to delete the virus files automatically.

Manually delete CA$HOUT from your computer

Note! Substantial notification about the CA$HOUT threat: Manual removal of CA$HOUT requires interference with system files and registries. Thus, it can cause damage to your PC. Even if your computer skills are not at a professional level, don’t worry. You can do the removal yourself just in 5 minutes, using a malware removal tool.

1. Boot Your PC In Safe Mode to isolate and remove CA$HOUT files and objects

Boot Your PC Into Safe Mode

1. For Windows 7,XP and Vista. 2. For Windows 8, 8.1 and 10. Fix registry entries created by CA$HOUT on your PC.

For Windows XP, Vista, 7 systems:

1. Remove all CDs and DVDs, and then Restart your PC from the “Start” menu.
2. Select one of the two options provided below:

– For PCs with a single operating system: Press “F8” repeatedly after the first boot screen shows up during the restart of your computer. In case the Windows logo appears on the screen, you have to repeat the same task again.

– For PCs with multiple operating systems: Тhe arrow keys will help you select the operating system you prefer to start in Safe Mode. Press “F8” just as described for a single operating system.

3. As the “Advanced Boot Options” screen appears, select the Safe Mode option you want using the arrow keys. As you make your selection, press “Enter“.

4. Log on to your computer using your administrator account

While your computer is in Safe Mode, the words “Safe Mode” will appear in all four corners of your screen.

Step 1: Open the Start Menu

Step 2: Whilst holding down Shift button, click on Power and then click on Restart.
Step 3: After reboot, the aftermentioned menu will appear. From there you should choose Troubleshoot.

Step 4: You will see the Troubleshoot menu. From this menu you can choose Advanced Options.

Step 5: After the Advanced Options menu appears, click on Startup Settings.

Step 6: Click on Restart.

Step 7: A menu will appear upon reboot. You should choose Safe Mode by pressing its corresponding number and the machine will restart.

Some malicious scripts may modify the registry entries of your computer to change different settings. This is why manual clean up of your Windows Registry Database is strongly recommended. Since the tutorial on how to do this is a bit lenghty, we recommend following our instructive article about fixing registry entries.

2.Find malicious files created by CA$HOUT on your PC

Find malicious files created by CA$HOUT

1. For Windows 8, 8.1 and 10. 2. For Windows 7,XP and Vista.

2. Restore files encrypted by CA$HOUT

Restore Files Encrypted by CA$HOUT

Ransomware infections like CA$HOUT aim to encrypt your files using an encryption algorithm which may be very difficult to directly decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that they may not be 100% effective but they may help you little or a lot in some situations.

Method 1: Scanning your drive’s sectors by using Data Recovery software.
Another method of restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:

• Stellar Phoenix Data Recovery Technicians License(Pro version with more features)
• Stellar Phoenix Windows Data Recovery
• Stellar Phoenix Photo Recovery

Method 2: Trying Kaspersky and EmsiSoft’s decryptors.
If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:

• Kaspersky Decryptors
• Emsisoft Decryptors

Urgent! It is strongly advisable to first remove the CA$HOUT threat before attempting any decryption, since it may interfere with system files and registries. You can do the removal yourself just in 5 minutes, using an advanced malware removal tool.

Method 3: Using Shadow Explorer

To restore your data in case you have backup set up, it is important to check for shadow copies in Windows using this software if ransomware has not deleted them:

• Shadow Explorer

Method 4: Finding CA$HOUT decryption key while it communicates it via a network sniffing software.

Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
