Mole virus Removal Guide
What is Mole ransomware virus?
Evolution of Mole ransomware
Mole virus functions as a ransomware which spreads via malicious spam emails disguised as USPS delivery problems. The virus adds .mole file extensions to files it corrupts and drops INSTRUCTION_FOR_HELPING_FILE_RECOVERY.TXT, which is the ransom note. So far, the criminals have released three versions of this virus – Mole, Mole00, Mole01, Mole02 and Mole03 ransomware.
The malware is programmed to encrypt files using an RSA-1024 encryption key, appending .mole file extension and demanding to pay the ransom. Indeed, its behavior barely differs from other file-encrypting viruses. This cyber infection is known to eliminate Shadow Volume Copies; so it prevents victims from recovering data using these data copies.
However, there is some good news – victims of the initial ransomware version can now decrypt files encoded by Mole crypto-malware. You can find its download link in the data recovery instructions provided below the article. In case you got attacked by an updated version of the crypto-malware, you can use data backups.
If the virus has already inflicted damage, do not consider paying the ransom as there are few chances of recovery. Though the decrypter was finally released, IT experts have found a new version which appends .mole00 file extension to the files.
Furthermore, it disguises under Oren Music Panel executable. It is suspected that the malware might be distributed via several distribution channels, including exploit kits and spam emails. Mole removal might be a better decision. Attempts to obtain decryption software from the cyber criminals might end up with money loss and further cyber infections Thus, we recommend employing ReimageIntego or Malwarebytes.
The virus starts its malicious task as soon as a person clicks on a link provided in the infected email. After clicking on it, people are redirected to the fraudulent MS Word Online site which informs that document cannot be opened in the browser and users need to download and install the latest plugin.
Probably, you can get a feeling that this button installs a payload on the system. According to the research, Mole virus is executed either from pluginoffice.exe or plugin-office.exe file from doc-14-8g-docs.googleusercontent.com. When malware executable is dropped and activated on the system, it shows a fake Display Color Calibration alert that informs about an inability to turn off Windows calibration management.
The purpose of this fake error message is to force victims to click on “OK” button. This button is designed to start ransomware execution processes. Then, the virus starts data encryption procedure, and once it's over the virus drops INSTRUCTION_FOR_HELPING_FILE_RECOVERY.TXT file on the desktop and each folder that includes crypted files.
This file is a ransom note where victims are informed that they have 78 hours to contact cyber criminals and learn how to obtain the decryption key. However, sending the unique ID number to firstname.lastname@example.org and email@example.com emails is not recommended.
We can assure that crooks will demand to transfer few Bitcoins, but you may not be satisfied with this purchase. You may never receive a decryptor, or it might be not working properly, or it might be infected. It’s important to remove Mole from the device if you want to continue using your computer safely. Hopefully, alternative data recovery methods will help you to recover at least some of the corrupted files until the official decryptor is released.
Update June 2017: Victims whose computers were affected by this notorious ransomware virus no longer need to sorrow for lost data because if you haven't deleted the corrupted files, you can decrypt them now for free. Researchers from CERT Polska reveal that they decided to take a look at a sample of this crypto-ransomware after one of the victims contacted them.
It turns out, they succeeded to perform a thorough analysis of the ransomware and also initiated a reverse-malware process. As a consequence, Mole decryptor was created. So if you were wondering whether to pay or not to pay the ransom, you can stop hesitating already and download the decryption tool to restore corrupted files.
We already mentioned this, but the ransomware removal must be performed before attempting to use a decryptor. You can find the link to download the decrypter in data recovery section below.
Mole ransomware spreads via fake USPS package delivery failure notifications and tricks people into installing a necessary plugin to view the details about shipping problems.
Versions of Mole ransomware
Mole00 ransomware virus. On July 4th, 2017, a new variant of Mole emerges. This time, the virus uses .MOLE00 extension to mark the encrypted files. After encrypting the data, the malicious program creates _HELP_INSTRUCTION.TXT file and saves it to every computer location that contains at least some corrupted files. The ransom note doesn't provide a particular ransom price but suggests visiting Mole00-02 payment website that asks paying 1 BTC to receive a data recovery software.
The ransomware was mainly distributed via email – scammers used USPS-themed spam campaign to trick unsuspecting victims into installing a malicious plug-in to view the attached message's content. The ransomware is highly dangerous, and so far there are no tools that could recover Mole00 file extension files for free.
Mole01 ransomware virus. Mole01 ransomware emerged for a short period but was quickly replaced by Mole02 ransomware version. The 01 version used _HELP_INSTRUCTION.TXT to provide instructions for victims. It also points to a dark web site accessible via Tor browser and also demands 1 BTC as a ransom.
Unfortunately, ransomware decryptors available today are not powerful enough to decrypt .mole01 file extension files. To restore encrypted files, we suggest using data backup or any data copies stored in email, online data storage accounts, and other places. Before you attempt to recover some files, remove Mole01 virus first.
Mole02 ransomware virus. MOLE02 version emerged on July 08, 2017. The virus completely corrupts the original file name and adds .MOLE02 file extension to it. The virus scans the entire computer system and corrupts all of the files with extensions from its target list. Following that, the virus creates and saves the _HELP_INSTRUCTION.TXT file as a ransom note.
The ransom note holds instructions on how to access the secret website with instructions on how to recover victim's data. The payment website suggests buying the “private key” for one Bitcoin. The victim has to enter one's victim ID and personal email address after transferring the ransom to criminals' Bitcoin address. However, a decrypter for MOLE02 is available, so we ask you not to pay the ransom!
Mole03 ransomware virus. Mole03 ransomware emerges on July 23. Reportedly, actors behind EiTest campaign distribute the virus via “The “HoeflerText” wasn't found” pop-ups. In other words, ransomware authors compromise legitimate websites and make them display the malicious pop-up.
Once the victim visits an infected site, the malicious script checks if the victim is using Google Chrome. If yes, it suggests installing a font pack that contains malware. If the victim uses Internet Explorer, the website automatically redirects the victim to a tech support scam site.
MOLE03 virus also uses _HELP_INSTRUCTION.TXT to send a message to the victim. It also points to the same payment website that demands 1 BTC.
There is no decryptor for Mole03 ransomware available. Therefore, if it locked your files, you will need to use alternative data recovery methods. Ideally, use a data backup. In case you never created it, try data recovery solutions listed below the article.
Techniques used to distribute the virus
Online security researcher Brad Duncan noted that Mole hijack occurs via malicious spam emails, which alert netizens about problems with package delivery. The subject line might include these names:
- Delivery problem, parcel USPS #number;
- New status of your USPS delivery code: #number;
- Our USPS courier can not contact you parcel # number;
- Please recheck your delivery address USPS parcel #number;
- Status of your USPS delivery ID: #number;
- We have delivery problems with your parcel # number.
However, there might be other email campaigns that distribute a malicious payload. Though, it is important to be careful and not to click on the links provided in the email that informs about delivery issues; especially, if you do not expect to receive any parcel. As we mentioned earlier, these emails have a link that leads to the fake Microsoft Office Online page which informs about a necessity to download a plugin to open the content.
This download button is infected and drops a malicious file on the system which generates another error message. Fake Display Color Calibration notification includes the “OK” button, which allows Mole ransomware to start damaging processes on the system as soon as it is clicked on.
Right after the project was launched, the developers of Mole malware decided to improve their distribution technique. The malware continues impersonating U.S. Postal Service emails. Besides disguising the malware in the attachment, now the developers have loaded more “malicious” content in the attached files.
They would hide Kovter (which now has its own crypto-malware – Kovter ransomware) and Miuref (alternatively known as Boaxxe) malware . The entire malignant content is packaged into plugin.zip folder. Naturally, within this folder, plugin.js is placed as well.
In order for Mole crypto-malware to execute and paralyze the system, Nemucod trojan is also included. Interestingly, the gearheads also revived another malware – Nymaim ransomware . It uses almost identical spam messages and includes the mentioned series of malware as well. On April 21, the crooks diverted from imitating USPS services to disguising under diverse lottery, parking notifications, and tax refund messages.
Remove Mole ransomware, get your files back
Having ransomware on the computer puts computer’s security and your privacy at risk, so remove Mole virus without a delay. This crypto-malware has already damaged your files; thus, you should not let it allow other viruses to enter the system and cause you more problems. We suggest you eliminate
We suggest you eliminate virus from the system as soon as you find a ransom demanding message and find out that you cannot access your files. Elimination requires using professional antivirus software or malware removal tools. We suggest performing this task using ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes.

However, you can use this method under one condition – System Restore feature needed to be enabled before Mole virus attack.
- Find an encrypted file you need to restore and right-click on it;
- Select “Properties” and go to “Previous versions” tab;
- Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.
Computer Emergency Response Team from Poland, known as CERT Polska, has reversed a sample of the malware and created a free decryptor that you can use. Download the Mole decryptor from their official page.
IMPORTANT. Victims of MOLE02 can decrypt their files using this decrypter.
Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Mole and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes
How to prevent from getting ransomware
Do not let government spy on you
The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet.
You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.
Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.
Backup files for the later use, in case of the malware attack
Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.
When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
