BlueCheeser ransomware – a file-encrypting parasite that urges payment of $400 in Bitcoin cryptocurrency

BlueCheeser ransomware
BlueCheeser ransomware is a malicious parasite that has already been detected by 44 antivirus programs

BlueCheeser ransomware is a malware string that employes the Advanced Encryption Standard[1] to lock up all files that are located on the infected device. Afterward, all filenames receive the .himr extension and the malware starts providing ransom demands via Instructions.txt Notepad message. BlueCheeser ransomware includes the crooks' Bitcoin wallet address and urges to transfer $400 in BTC. This is the total price required for the release of locked files. According to the English language that is used for writing the ransom message, hackers are targeting English-speaking people.

First discovered by a cybersecurity researcher named Raby,[2] BlueCheeser ransomware arrives at the computer system with the help of deceptive techniques such as email spam, hacked RDPs, cracked software, fake flash player updates, malvertising, or infectious hyperlinks. After the infiltration process, the ransomware virus brings the BlueCheeser.exe file to the Windows computer system and includes the executable in the Windows Task Manager section.

According to VirusTotal provided information,[3] BlueCheeser ransomware has been detected by 44 AV engines out of the total 70 available ones. Some of the detection names include Gen:Heur.Ransom.Imps.3,  Trojan.Encoder.30952,  HEUR:Trojan-Ransom.MSIL.Gen.gen, Trojan:Win32/Occamy.C, Ransom_Gen.R011C0WAC20, and others.

BlueCheeser ransomware alters the Windows Registry and Task Manager for its own purposes. The cyber infection ensures that it is booted every time when the infected computer turns on. In order to do this, the malware includes specific keys and processes to the sections that are mentioned above.

Additionally, BlueCheeser ransomware can be able to scan the entire computer system once in a while and look for encryptable documents. The malicious actors want to make sure that no components have been left unencrypted. 

Afterward, BlueCheeser ransomware uses the Advanced Encryption standard to lock up files such as word documents, PDF documents, excel sheets, audio files, video files, .zip content, .exe components, and many more. Once the encryption is performed, the user cannot access the blocked files properly anymore.

BlueCheeser ransomware is a dangerous computer virus that appends the .himr extension to each filename of the encrypted components

However, you should expect that BlueCheeser ransomware will try to harden the recovery process for you. This can happen by deleting the Shadow Volume Copies of encrypted files and documents by running specific PowerShell commands. Also, both encryption and decryption keys are safely stored on a remote server that is reachable only for the criminals.

BlueCheeser ransomware developers try to frighten the victims by claiming that their files will be lost forever if they do not agree to pay. This type of claim is written as the last line of the Instructions.txt ransom message: 

Looks like all your desktop files have been encrypted!
To decrypt, send $400 to the bitcoin wallet: 43IU64UGG645G37I670IITYYR5093U55KJ5HE
RIP Your personal files if you dont pay…

BlueCheeser virus might also target your Windows hosts file and aim to permanently damage it. This type of activity is performed when the cybercriminals want to prevent users from entering various cybersecurity forums and pages. 

However, you should know that there is a big reason not to pay the cybercriminals, no matter how frightening BlueCheeser ransomware looks to you. The main fact is that hackers are very likely to scam their victims. They might provide you a fake tool or no key at all after you pay them the demanded ransom and just simply run off uncaught.

BlueCheeser ransomware makes the computer system vulnerable to other infections and might even disable the antivirus software to let in some other threats. Ransomware viruses are often used for the distribution of other malware such as trojans. These parasites aim to steal personal information and money, mine cryptocurrency, overuse the CPU power.

If you are looking for a way to avoid these possible consequences, the best thing to do would be to remove BlueCheeser ransomware from your Windows computer system and get rid of all the additional malicious products that were injected in your device during the ransomware attack.

You can successfully complete the BlueCheeser ransomware removal with the help of reliable antimalware products that will take care of the task for you. A piece of advice would be not to try to get rid of the cyber threat on your own as there is a chance of failure due to the complexity that this parasite has.

When BlueCheeser ransomware is permanently gone, you should start thinking about data recovery possibilities. Travel to the very end of this article where you will find three file restoring options some of which might appear really handy.

Be aware of unknown email messages

Ransomware is quite commonly delivered through infectious emails that pretend to be official letters from healthcare, financial, or shipping organizations. Such messages can travel to your email spam section but might also fall in the inbox. Regarding this fact, it is very important to measure the expectancy of such a letter.

According to NoVirus.uk experts,[4] if you have not been waiting for a particular email message to come, you should think if its links or attached documents are worth loading. If you have already downloaded the questionable file, do not risk your computer's safety by launching the attached component without scanning it with a trustworthy antivirus program.

Furthermore, you should always check if the message is coming from an official email or some type of weird-looking one. Plus, if you find any grammar mistakes in the contact of the text message, this might be an accurate sign that you are dealing with something unknown as reliable companies would not leave any mistakes in their official texts.

To add, ransomware infections can also get distributed through other sources such as hacked RDPs that included weak passwords or none at all, fake flash player updates, malvertising ads, etc. You should always be careful while browsing the Internet and make sure to employ a reliable antivirus product.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from BlueCheeser and other ransomwares, use a reputable anti-spyware, such as Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer various losses due to cyber infections or their own faulty doings. Software issues created by malware or direct data loss due to encryption can lead to problems with your device or permanent damage. When you have proper up-to-date backups, you can easily recover after such an incident and get back to work.

It is crucial to create updates to your backups after any changes on the device, so you can get back to the point you were working on when malware changes anything or issues with the device causes data or performance corruption. Rely on such behavior and make file backup your daily or weekly habit.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware occurs out of nowhere. Use Data Recovery Pro for the system restoring purpose.
