Remove RIP Imao Ransomware (.jcrypt Files)

This post is all about the hazardous crypto-virus called RIP Imao. Part of the page are Removal Guide, File Recovery options, as welll as Computer Protection.

RIP Imao is the tag of the new ransomware that is a huge threat to computer files and system as well. If your files are manifesting the .jcrypt extension, it denotes that computer is infected with the said ransom virus. The goal of RIP Imao is to block users from accessing their files by applying a high level type of encryption and then, it will demand for ransom money as payment for the decryption software that is being offered by the attackers.

Jcrypt File Decryption

As of this moment, there is no alternative solution to decrypt the entire .jcrypt encrypted files. Third party file recovery applications are not considered helpful because these programs were made to recover deleted files. Remember that .jcrypt files were encrypted and only a decryption software from hackers is the sole remedy to this kind of attack.

Attacker’s specifically wrote a ransom note telling victims about the current file situation and also gives instructions to send 1 Bitcoin on the provided BTC wallet as payment. After paying, victims should contact the hackers in order to unlock the encrypted files using the provided key.

Although paying the ransom money is the only hope left to recover the .jcrypt files, malware researchers are not recommending this option. There are many cases that the offenders flee away after receiving the payment and thus, the promised decryption software or key was not provided.

RIP Imao Sources and Prevention

This ransomware spreads over the web using different channels such as spam emails, software piracy, serial key generator, web injector, bogus freeware, fake software update, and brute force by exploiting software vulnerabilities. As such, it is important that web user must know the basics of preventing the RIP Imao infection by practicing the following:

  • Do not open suspicious email especially those with attachment and link.
  • Avoid cracked applications as it often contains malware in the setup file.
  • Stay away from unknown and suspicious sites because it may have a script to automatically download RIP Imao.
  • Freeware or shareware being offered on questionable file servers may also contain the RIP Imao virus.
  • Regularly update the operating system and software to patch the present vulnerabilities.

Above all, it is crucial to protect the computer with an effective anti-virus or anti-malware application that guards the internet transmission and blocks the downloads of malicious files. Lastly, make file back up as part of the routine so that you can restore files anytime if ever there is a ransomware attack.

Backup your files

One important step before proceeding with the procedures below is to backup your files. Ransomware are not the same. Each has its unique sets of payloads aside from encrypting the files with complex method. Others tend to delete the infected files after certain period, while others keep them concealed on hidden places. In addition, ransomware decryption tools are not guaranteed to be perfect, there are instances that files suffer from damages during the decryption process.

So, create a backup copy of your entire RIP Imao encrypted files right now.

Recover Files from RIP Imao Ransomware Infection

On this section, we will provide ways to decrypt files infected with RIP Imao ransomware. Aside from dedicated decryption software and common tools, other options for file recovery are provided. As much as we can, we will update this area whenever there is new and more suitable decryption tool was made available.

Decrypting RIP Imao infected files with Emsisoft Tools

This service from Emsisoft is helpful in unlocking encrypted files without paying the ransom. It gives three ways to detect the ransomware and provide suitable recovery method:

Upload ransom note – This is usually the .txt or .hta files that was generated by RIP Imao ransomware.

Upload the encrypted file – The actual encrypted file. Choose the one that is less than 8MB in size.

Contact information – Enter the email address or any links provided as it appears in the ransom note of RIP Imao virus.

Emsisoft Tools

After submitting any of the appropriate data, Emsisoft will attempt to identify the ransomware and provide keys if there are available.

Option 1: Windows Previous Version Tool

Windows Vista and Windows 7 have a feature called Previous Versions. However, this tool is only usable if restore point was made prior to ransomware infection. To use this tool as "recovery option" for files encypted by RIP Imao virus, please follow these steps:

1. Open My Computer or Windows Explorer.

2. Right-click on the affected files or folders. From the drop-down list, please click on Restore previous versions.

3. New window will open display all backup copy of files and folders you wanted to recover. Choose the appropriate file and click on Open, Copy, or Restore. Restoring selected files overwrites the current locked files on the computer. The tool is not actually recovering files encrypted by RIP Imao. Instead, it restores files from backup copy.

Option 2: Use ShadowExplorer to restore files encrypted by RIP Imao Ransomware

Just like Previous Version tool, ShadowExplorer is taking advantage of shadow copy created by Windows. This tool allows you to retrieve older version of files before it was encrypted by RIP Imao ransomware.

1. Download ShadowExplorer from the official web site.

2. Install the program with the default settings.

3. The program should run automatically after installation. If not, double-click on ShadowExplorer icon.

4. You can see the drop-down list on top of the console. Please select proper drive and the most recent point-in-time shadow copies of files you wish to restore prior to RIP Imao ransomware infection.

5. Right-click on the Drive, Folder, or File you wish to restore and click Export...

6. Lastly, ShadowExplorer will prompt for location where you want to save the copy of recovered files.

How to protect the computer from RIP Imao ransomware?

After the removal of the ransomware, it is important to prevent similar incident from happening again. In order to protect the computer effectively, computer user must know how RIP Imao ransomware was able to infect the computer. To minimize the possible infection, staying away from the common sources of this virus is crucial.

How RIP Imao ransomware can infect your computer?

The method of infecting the computers was found to be similar as other common viruses. Though, ransomware like RIP Imao is seen to have efficient deployment via spam email messages, web injectors, malicious software installers, misleading online advertisements, and through another virus infection.

Once the virus is executed, it immediately infects the system. Then, RIP Imao ransomware communicates to remote server so that unique key can be generated for the specific computer. After acquiring the key, it starts to decrypt target files using a complex method that is almost unbreakable. On the last stage of the attack, RIP Imao ransomware demands for ransom money as payment for the decryption tool. To further understand the attack scheme, we have included an infographic below.
