However, a current version of the ransomware does not provide any ransom note. It’s possible that developers are working on the technical side of the program and will include the Bitcoin[1] demanding message later. Thus, if you accidentally encounter this cyber threat, you should remove CryptolockerEmulator ASAP and do not wait until it is upgraded.

Security tips for ransomware prevention

File-encrypting viruses spread similarly. Most of the time, the payload is attached to spam emails that pretend to be legit letters from banks, government institutions or well-known companies. Social engineering helps crooks to trick people into opening the obfuscated email attachment and download malware to the system.

Therefore, users are advised to be careful with malicious spam emails and open attachments only when you are 100% certain about its credibility and safety. Additionally, security researchers from Los Virus[2] warn about other methods used by developers of crypto-viruses:

  • malicious ads placed on legit and high-risk websites;
  • bogus downloads and fake updates;
  • exploit kits.

Computer users should not click on ads that seem “too good to be true” or offer to download missing updates. In addition, security alerts or notifications about detected viruses never show up in the form of a pop-up. Thus, never click those entries!

Finally, keep your programs and operating system up-to-date because ransomware can take advantage of vulnerabilities and infiltrate the device. Moreover, you should install an antivirus program and create data backups.[3]
