Remove DERZKO ransomware (Decrypt Locked Files)

Delete DERZKO ransomware From Computer

DERZKO ransomware is another hazardous kind of file-encrypting virus that belongs to the NEFILIM ransomware family. It has been specially designed by a group of vicious hackers with their sole motive to encrypt data stored inside the Windows computers and force victims to pay them an amount of ransom for their decryption. This deadly crypto-malware uses a very strong cryptography to lock videos, audios, documents, spreadsheets, presentations etc. and hence, those files are no longer accessible. After that, they can only be accessed by using the proper decryption software that is allegedly put on attackers’ server.

Depth Analysis Of DERZKO ransomware:

Files encrypted by DERZKO ransomware can easily be identified as it renames them by appending “.DERZKO” extension with each of them as suffix. Following successful encryption, this hazardous threat leaves a ransom note titled “DERZKO-HELP.txt” on each affected folder and informs victims about the unpleasant situation. It also instructs the affected people to contact the attackers via the provided email addresses to get more details. The only way to restore the locked data is by paying ransom money to the criminals. If they don’t make the payment or contact the crooks, then the compromised data will be leaked on the websites.

Should You Pay The Ransom?

No matter what situation is, you should never consider dealing with DERZKO ransomware authors as you have absolutely no guarantee that they will deliver the required tool even after taking the ransom. It has been tendency of such hackers that they often disappear once the payment is made and cause them to lose both files as well as money. At several occasions, they provide rogue software in the name of decryption tool which causes even more hazards to the work-station once installed. So, you should never trust such people and find any alternative way to recover the files.

Infiltration of DERZKO ransomware:

Ransomware or any other type of cyber threats often rely on novice users to get into their PC systems who do not pay enough attention to details and skip through steps or ignore red flags on suspicious online material. Malspam campaign is the most common and popular method to proliferate file-encoding viruses. You can receive emails from an unknown sender that might pretend to be from well-known companies however, often include malicious attachments. Some users tend to read all these spam emails and download files attached to messages.

Unfortunately, such behavior leads to infections and payload dropper activities.
