What is CryptoPatronum ransomware?

CryptoPatronum ransomware – a file-encrypting parasite that requires a ransom equal to 1 Bitcoin or 50 Ethereums in exchange for file release

CryptoPatronum malwareCryptoPatronum ransomware is a dangerous cyber infection that urges for 1 BTC or 50 Ethereum as the payment for the decryption key

CryptoPatronum ransomware, also known as Enc ransomware, is a cryptocurrency-urging cyber infection that has emerged in the second half of January 2020. This malicious strain is recognized from the email address and .enc extension that it appends to the encrypted files that are modified by the AES-256 cipher.[1] For example, if you had a document named lists.docx, the file will be renamed to and you will not be able to access it properly anymore. Regarding this fact, the CryptoPatronum ransomware developers want to “help” people to get their files and documents back by providing specific ransom demands via HOW TO RECOVER ENCRYPTED FILES.txt text message.

The criminals are orientated in earning 1 Bitcoin that is around $9000 or 50 Ethereum that is approximately $8500. CryptoPatronum ransomware provides information on how to obtain Bitcoins or Ethereum directly in the ransom note by adding certain website URLs. The hackers also include the Bitcoin and Ethereum wallet addresses where the demanded price needs to be transferred. Furthermore, these people offer to provide evidence of the decryption tool's existence by encouraging the victims to send them 3 files that hold no more total size than 10 MB for free recovery.

Name CryptoPatronum ransomware

Category Ransomware/malware
Encryption This malicious parasite locks all types of files and documents by employing the AES-256 cipher. All the affected components end up with the appendix
Ransom note The malicious actors provide the HOW TO RECOVER ENCRYPTED FILES.txt message after locking all files. This note holds all the conditions required for the ransom transfer
Payment The hackers appear to be very greedy, they urge for a payment of 1 Bitcoin that approximately equals $9000 or 50 Ethereum that is around $8500
Distribution Criminals use stealth distribution techniques to spread their created malware. Most of the time, ransomware is delivered via email spam and malicious attachments that come together with the phishing message. Furthermore, you can receive the dangerous infection through a hacked RDP, cracked software that is placed on p2p networks, malvertising ads, infectious hyperlinks, fake software updates, etc.
Removal Once you spot the ransomware virus on your Windows computer system, you should take action against the parasite immediately. This includes fast termination by employing a reliable antimalware product. We recommend not trying to get rid of the cyber threat on your own in order to avoid possible mistakes
Data recovery If you are looking for ways to restore your files and documents, you can try some of the techniques that are described at the end of this article. You should be aware that the cybercriminals are focused on their goal only and they might not provide you with a decryption tool after the payment is processed
Fix software If the ransomware virus or any additional malware has damaged some system components, you can try fixing the compromised areas with a repair tool such as FortectIntego

CryptoPatronum ransomware alters the Windows Registry to include malicious registry keys that allow the virus to boot itself up during the computer activation process, scan the system for encryptable files, launch the encryption code, and run other background processes. Besides messing with the Registry, the cyber threat also injects malicious processes into the Windows Task Manager section one of which is named crss.exe.

Even though CryptoPatronum ransomware might aim to evade antivirus detection, this malicious threat has been spotted by 52 antimalware programs out of the total 69, according to VirusTotal provided data.[2] However, if the virtual parasite aims to block your antivirus product, you might have difficulties while dealing with the CryptoPatronum ransomware removal process. In this case, you have to boot your computer in Safe Mode with Networking or activate the System Restore feature.

Furthermore, CryptoPatronum ransomware might try to harden the recovery process of locked data files as much as possible. It might run the “vssadmin.exe delete shadows /all /Quiet” command via PowerShell and permanently terminate all the Shadow Volume Copies of encrypted files. Also, it might be able to damage the Windows hosts file in order to prevent you from accessing security-related sources where you could get valuable information on file recovery.

After the decryption process, the cybercriminals store both encryption and decryption keys on remote servers that are reachable only for the owners themselves. This type of thing also hardens the recovery process for the user. However, you should not let CryptoPatronum ransomware frighten you even though the hackers will try to convince you that the only way of restoring your data is by paying the ransom and other tools would not work:

Your files are now encrypted!

* Do not try to decrypt your data using third party software, it may cause permanent data loss.
* Decryption of your files with the help of third parties may cause increased price
(they add their fee to our) or you can become a victim of a scam.

Even though CryptoPatronum virus is likely to have the decryption key for your files, paying the ransom price cannot make you 100% sure that you will receive the tool after all. The cyber crooks could decide to scam you and run off with your money. This way you will be left with nothing else just an empty bank account as paying the demanded 1 BTC or 50 Ethereum ransom is a big amount of money to spend.

The main reason why CryptoPatronum ransomware orders cryptocurrency payments instead of regular dollar transfers is that Bitcoin or Ethereum payments do not require entering any personally identifiable information that the cybercriminals find very beneficial as they can stay untracked and anonymous all of the time.

CryptoPatronum ransomware can be really frightening not only with its ability to encrypt data and big ransom payments but also with the possibility that it might bring other malicious infections into the computer system. Some ransomware viruses can bring others of their kind or can distribute Trojan viruses. The last ones are known for their ability to steal personal information, swindle money, damage software, mine cryptocurrency, and so on.

The only way to avoid risks of getting an additional malware infection is to remove CryptoPatronum ransomware from your Windows computer system permanently. This type of process can be successfully performed with a reliable virus removal tool. Afterward, go to the end of the article and view all possible data recovery solutions. By the way, if the malware has caused any type of damage to your computer, you can try repairing the altered areas with the help of software such as FortectIntego.

The most popular distribution ways of ransomware viruses

IT specialists from[3] claim that ransomware infections are most commonly spread through email spam campaigns. The criminals often pretend to be from reputable organizations such as FedEx or DHL shipping companies and drop fake notes to random potential victims. These messages often come with an executable or word document that is the hidden malicious payload. Sometimes the hackers can include an infected link directly into the email.

Continuously, the ransomware-related payload can be delivered through multiple sources at a time. Even though email spam is considered to be the most common way employed by the crooks, these people also use other methods such as:

  • Injecting the malicious payload into software cracks. You can get cracked products from p2p networks such as The Pirate Bay, eMule, and BitTorrent.
  • Hacking RDPs. RDP that includes weak password protection or none at all is at risk of getting hacked by various cybercriminals.
  • Malvertising. Ransomware virus can get delivered through malicious advertisements that show up on third-party websites.
  • Fake software updates. Some hackers camouflage their products as fake flash player or JS updates and encourage users to falsely upgrade their software. During the false update process, the malicious payload is loaded.

Learn how to protect your device and files from ransomware

Once you have gained a little bit of knowledge in the ransomware distribution field, you can now start learning how to protect your device and files from these dangerous parasites. First of all, make sure that you have got strong antivirus protection. Update this type of tool whenever you are required to do it. It is necessary for proper operating.

Continuously, you should be careful with random email messages that fall into your email box. Avoid opening any letters that come to the spam section and better delete them immediately. If you have received a message that you were not ever expecting to get, do not feel afraid to contact the company that supposedly sent the letter. Also, check the text for possible grammar mistakes that should not be found in an official letter, do not open any attachments that you are not sure about.

Another piece of advice would be to prevent yourself from visiting unsecured p2p networks[4] and other websites that can hold infectious hyperlinks or advertisements. If you are ever provided with a bogus update request, do not rush to upgrade your software before checking the official update releases at the developer's website. Also, proper RDP configuration should include a strong and reliable password that consists of random letters, numbers, and symbols.

Your files can be protected by always creating backups for important data. These types of components should be saved on a remote device such as a USB flash drive, CD, or DVD. Also, you can store some information on a remote server such as iCloud or Dropbox.

Advanced removal possibilities for CryptoPatronum ransomware

CryptoPatronum ransomware removal should be taken care of as soon as you spot the first symptoms of infection that usually include encrypted files and the specific ransom note. Be aware that you should not try to delete the malware on your own as this type of process can be too difficult for even a highly-experienced user.

You should employ only reliable antivirus tools to remove CryptoPatronum ransomware from your Windows computer system. Furthermore, if you think that your system is suffering from some type of damage, you can check such speculation by downloading a tool such as 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.
