If you haven’t been formally acquainted with Cosanostra ransomware, it is a form of cyber threat which uses encryption algorithms which are military-grade! Once you’ve been hit with these variants, your data is rendered useless and the encryption process of this ransomware starts as soon as it has infiltrated your system. Once the process is complete, you will start seeing files that have the extension ‘.cosanostra’.
The Ransom Note
Once the encryption process is complete, the ransomware variant leaves a file named ‘#RECOVERY_FILES#.txt’ on every encrypted folder. This is also where you will find out that Cosanostra ransomware is a variant of the Garrantdecrypt family – which makes it twice as dangerous and persistent.
In the ransom note, the perpetrators will threaten the victim with a ransom amount and then ask them to contact their alleged saviors at cosanostra19@protonmail.com. This is where we will recommend all our readers to avoid contacting the cyber criminals at all.
The Ransomware Removal Process
All the victims that have encountered a cyber infection from the Cosanostra strain of ransomware make the biggest mistake of focusing on recovering their data before terminating the threat. This is because unless the problem hasn’t been averted, it will continue to encrypt the system’s files.
This is where the victims will have to thoroughly clean their system and remove the ransomware with the help of professional grade anti-ransomware programs. We recommend the use of programs such as Plumbytes Anti-Malware, Malwarebytes, and Reimage. They have the ability to clean all the problems in the system before they cause any further damages.
You would also need to make sure that the problem has completely been eliminated from your system before moving onto data recovery. This can be done by running double-check with the above mentioned programs or with the help of alternative programs.
Data Recovery
A tried and tested method of getting back your encrypted files once the problem has been removed from the system is with the help of programs like Data Recovery Pro. All you would need to do is to download and install this program onto your system and then follow their simple steps. It will automatically scan your system for all the encrypted files and then begin restoring them so you access them.
While all of this may seem simple, we will also recommend beginning securing your system with the proper anti-malware measures. Remember that preventative measures always work better as opposed to post disaster measures.
