MIRCOP ransomware removal instructions

What is MIRCOP?

MIRCOP (also known as "Microcop" or "Crypt888") is a ransomware virus distributed via spam emails. The infected document appears as a Thai customs form, which is used during import and export of various goods. Note. however, that this document has a number of embedded MS Windows PowerShell scripts that download malware. Once infiltrated, MIRCOP encrypts various files stored on the victim's computer. During encryption, MIRCOP appends the name of each compromised file with .lock. For example, sample.jpg is renamed to lock.sample.jpg. Furthermore, MIRCOP changes the desktop wallpaper.

The new desktop wallpaper contains a message demanding a ransom. Regular ransomware attempts to sell victims a decryption tool, however, MIRCOP accuses users for supposedly stealing money (48.48 Bitcoin, which is, at time of writing, equivalent to $32336.16) and demands that the funds are returned. If the victim refuses to pay, their files will supposedly remain encrypted forever. Unlike other ransomware, MIRCOP provides no detailed payment instructions - it simply gives a Bitcoin wallet address where the money should be sent. This ransomware claims to assume that victims already know how to pay, since they supposedly stole the money in the first place. This behavior is unusual to ransomware-type viruses, since, as mentioned, developers of ransomware usually attempt to sell a decryptor with a price fluctuating between 0.5 and 1.5 Bitcoin ($333.5-$1000.5). Accusing victims of theft and then demanding a refund (in this case, 48.48 Bitcoins) is new behavior. This is the largest ransom of this type seen to date. Fortunately, AVG has developed a tool capable of decrypting files compromised by MIRCOP ransomware (download link). Thus, there is no need to pay the ransom.

Research shows that developers of ransomware-type viruses commonly ignore victims, despite payments made. Therefore, paying is risky and will not yield any positive results. In doing so, you will lose your money and support the malicious businesses of cyber criminals. For these reasons, we strongly advise you not to contact these people and to ignore all demands to pay. Furthermore, ransomware-type viruses are very similar. There are dozens of malware infections sharing similarities with MIRCOP including Anonymous Pop-up, SATANA, and CryptoRoger. Most ransomware encrypts files and makes ransom demands. These viruses are often distributed using fake software updaters, malicious email attachments, peer-to-peer (P2P) networks, and trojans. To protect your system, use a legitimate anti-virus or anti-spyware suite and keep your installed applications up-to-date. In addition, never open any attachments sent from unrecognized/suspicious email addresses and, if possible, download your desired files/programs from trusted sources (for example, official download websites). The key to computer safety is caution.

Ransom demanding message:

Hello, You’ve stolen 48.48 BTC from the wrong people, please be so kind to return them and we will return your files… Don’t take us for fools, we know more about your than you know about your self. Pay us back and we won’t take further action, don’t pay and be prepared. 3BGrRU4mhAkCFx1s3Z4yQLCbNg29wtBFj8

A new variant of this ransomware is calling itself “Zuahahhah”. When encrypting files this ransomware will add “Lock.” at the beginning of the file name. For example 1.jpg after encryption will be renamed to Lock.1.jpg

A variant of this ransomware called "END of North Korea". Adds “Lock.” at the beginning of the file name. For example 1.jpg after encryption will be renamed to Lock.1.jpg

Text in the wallpaper set by this ransomware:

Chinese son of a Chinese boy
Don't promise what you see and hear!
Today is the screen war, the battle machine was tomorrow,
Child, women, kill the president!
You think you are the chosen people of God, but you are in your dreams. I think you guys are the chosen ones,
Be in a dream.
I wake up in this dream.
You guys are people who have no conscience.
Get out of Seoul from the sea to the river!
They stopped invading somewhere else in Seoul.
The Republic of Korea's conscience doesn't last long.
Get our of our land Seoul.
Seoul is ours.
Busan belongs to us.
I'm done with you!
END OF North Korea

Update 27 February, 2017 - Security researcher Jan Poulsen discovered a builder for this ransomware - this means that this ransomware is offered as Raas (ransomware as a service) and anyone who downloads this builder can create and spread this ransomware. Due to this fact the distribution of Crypt888 ransomware can increase. Notice that the decrypter still works and the files encrypted by this ransomware can be decrypted for free.

Step 2

Log in to the account infected with the MIRCOP virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.

If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.

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 MIRCOP 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 MIRCOP 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 MIRCOP 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 MIRCOP, 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 encrypting ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and Malwarebytes Anti-Ransomware, which artificially implant group policy objects into the registry to block rogue programs such as MIRCOP ransomware.)

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