CryTekk virus Removal Guide
What is CryTekk ransomware?
CryTekk ransomware is a virus that not only operates as an extortionist but also tries to direct users to spoofed PayPal payment page
CryTekk ransomware is a new cyber threat that not only locks data but also directs users to a phishing site in order to gain access to victim's personal data
CryTekk ransomware is a file locking virus that is based on HiddenTear open-source project. After the infiltration, malware performs several changes to the system and begins a scan, looking for personal files like pictures, documents, videos, audios, databases, etc. Once located, the cyber threat makes use of AES encryption to encode data and appends .locked file extension. Next, CryTekk ransomware contacts a remote server that is controlled by hackers to send the encryption key and upload a ransom note README.html onto victim's machine. The message from cybercriminals explains what happened to their personal files, and asks users to pay $40 in BTC and contact hackers via CryTekk@protonmail.com. This malware string is poorly written and can be decrypted. However, the “catch” is to make users disclosed their credit card details on a spoofed PayPal page.
|Extra element||Phishing via spoofed PayPal page|
|Ransom size||$40 in BTC|
|Elimination||Use powerful anti-malware software|
|Damage removal||Make use of ReimageIntego|
While combining ransomware functionality with other threats (such as banking trojans, data-stealers, cryptominers, etc.) is not uncommon, CryTekk ransomware authors added a new element that was never used before – phishing. In fact, the size of the ransom makes researchers believe that the main goal is not $40, but the credit card details disclosure, which would be used for unauthorized bank account use or could be sold on the Dark Web.
CryTekk ransomware drops the ransom note that states:
YOUR FILES HAVE BEEN ENCRYPTED!
Files have been encrypted! and Your computer has been limited!
To unlock your PC you must pay with one of the payment methods provided, we regularly check your activity of your screen and to see if you have paid. Paypal automatically sends us a notification once you've paid. But if it dosen't unlock your PC upon payment contact us
Reference Number: CT-[redacted]
When you pay via BTC, send us an email following your REF Number if your PC dosen't unencrypt. Once you pay, Your PC will be decrypted. However if you don't within 14 days we will continue to infect your PC and extract all your data and use it.
Google 'how to buy/pay with bitcoin' if you don't know how. To pay by bitcoin: send $40 to your unique bitcoin address b>[redacted]
Along with the usual payment method, CryTekk virus authors offer to pay via the popular payment site PayPal. As soon as victims click on the “Buy Now” button, they are redirected to a quite legit looking site. There, users are asked to enter their credit card details and later personal information, such as name, date of birth, address, phone number, and other data. Once they proceed, a message pops up, claiming that the account restoration was successful.
While it is an obvious scam, it might be entirely believable for those who never encountered a ransomware infection before. Without a doubt, users should remove CryTekk ransomware as soon as possible and ignore criminals. The scheme is merely a trick to disclose valuable personal information and credit card details.
For CryTekk ransomware removal, you should rely on powerful security software. Be aware that not all tools might recognize the threat, so a scan using multiple apps might be needed. After the elimination of the virus, you should scan your machine with ReimageIntego in order to restore its functions to the original state.
You can then contact the security researcher Michael Gillespie for free decryption, recover data from backups or try third-party software as a last resort.

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.
