Keep Calm ransomware virus is real – unlocks your files, asks for $250

Keep Calm ransomware

KeepCalm ransomware is a new computer virus that acts like a typical screen-locking ransomware. The virus is based on EDA2 malware[1], and during the encryption, it marks each affected file with .locked file extension. The ransomware then changes desktop wallpaper with an image called wall.jpg, which represents an ASCII image of skull and a few lines, saying:

KEEP CALM AND RECOVER YOUR FILES

Keep Calm virus then drops a ransom note called Instructions.rtf. It explains that the computer has been “hacked” and that files stored on it were encrypted. As usual, the ransom note provides the price of the decryption software needed for data recovery, or, in other words – a ransom. Cyber criminals want 0.1 BTC per one infected computer, approximately $250.

The note also contains statements urging the victim to pay the ransom within one week to “prevent them from being leaked.” The criminal also suggests writing to luisa91@you-spam.com and providing date of the transaction, PC’s name and also the email address to which the victim wants to receive the decryption key.

Surprisingly, the developers of the ransomware state that they “are business people and treat customers well” if they follow “what they ask.”

If your files were corrupted by this ransomware, we highly recommend that you do not pay the ransom. Considering that the ransomware is based on an open-source ransomware, malware analysts might find it easy to reverse the encryption process and create a free decryption tool. Therefore, to prepare your PC for further usage, we highly recommend you to remove Keep Calm virus using Reimage or another anti-malware software.

It is important not to mistake the described ransomware for KeepCalm virus, which is one of Globe Imposter viruses. This piece of malware adds .keepcalm file extensions and drops HOW_TO_BACK_FILES.html file (the ransom note). No matter which ransomware compromised your files, your aim is to complete Keep Calm removal as soon as possible.

Ways to get infected

Computer viruses can infect your computer in various ways. Usually, they travel via deceptive emails composed by cybercriminals. Such emails are designed to spark victim’s interest in the attached file that carries the malicious payload. It can be a ZIP, DOC, or JS file. Of course, the file format can differ.

It is highly advisable not to open email attachments or questionable links included in an email you received from a stranger. What is even more important is that you check the sender of the email – you must be sure that it is a trustworthy sender and not some fraud trying to impersonate an employee of some well-known company.

Cyber security experts believe that the virus won’t be distributed using more sophisticated malware distribution techniques used by ransomware professionals. It is highly unlikely that it will be distributed via exploit kits, malvertising[2], Trojans or other measures taken by developers of Cerber or CryptXXX ransomware.

However, if you want to protect your PC from all kinds of ransomware viruses, you should use several layers of protection such as anti-malware software, data backup and avoidance of suspicious Internet websites. For more security-related tips and tricks, visit NoVirus.uk site[3].

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Keep Calm from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

To restore your files, you should use a data backup that you created at some point in the past. However, in case you forgot to do it, try one of the suggested data restoration alternatives.

If your files are encrypted by Keep Calm, you can use several methods to restore them:

Run Data Recovery Pro

Looking for a tool to decrypt those .locked file extension files? If so, you might be interested in trying Data Recovery Pro. Although this tool isn't created to restore files encrypted by ransomware, in some cases it helps to restore some files. Therefore, you can't lose anything by giving it a try.

Restore using Volume Shadow Copies

Volume Shadow Copies can and should be used for data recovery, however, ransomware viruses tend to delete these copies after encrypting all data on the compromised computer. Luckily, even computer programs fail to complete certain tasks in certain circumstances. To find these copies and restore your files, use ShadowExplorer software.

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Keep Calm and other ransomwares, use a reputable anti-spyware, such as Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware
