Wiki virus Ransomware spreads its infection through commonly used internet services such as spam e-mail campaigns, unreliable software download channels and fake software updaters. Once the PC is infected, Wiki virus searches the system for targeted system & user file extensions. When found, it encrypts the files using strong Encryption Algorithms & makes them instantly unreadable. It further drops a ransom-note on desktop of the infected system.
The note suggests the victim to pay the required ransom amount in Bitcoins to purchase Wiki decrypter. Any attempt of renaming the encrypted files or trying to decrypt using third party software may lead to permanent data loss.

The latest member of Dharma Malware Family, Wiki Ransomware is currently posing as a menace to the computer users around the world. It stealthily infects the system via commonly used internet services, encrypts the files & instantly makes them unreadable to the users.
Wiki Ransomware uses highly-complex encryption methods to encrypt the files. The encrypted files are renamed by appending-
For example, a file named “image.jpg” might be renamed as image.jpg.id-1E757D00.[email@example.com].wiki.
Certain file extensions that Wiki Ransomware is able to encrypt are-
The encrypted files are instantly made unreadable & hence, it restricts the users from accessing/opening the files.
It has been found that the threat behavior of Wiki File Virus shares some common traits with other Ransomware infections such as Maze 2019, MedusaLocker & Deal. These crypto-viruses encrypt the files & demand handsome amount for decryption. The major differences in these Ransomware infections are type of encryption algorithms used & amount of ransom demanded, which usually ranges between three-digit to four-digit sums in USD.
However, the hackers demand ransom in digital currencies so as to avoid being tracked by the cyber-security analysts.
Once the targeted files are encrypted, Wiki Ransomware drops a ransom-demanding note on the victim’s desktop. This note is in a text format & named as “FILES ENCRYPTED.txt”.
The note explains the current situation of the PC & asks the victim to contact the hackers to get the encrypted data restored.
In addition to that, a pop-up window covers the screen, which contains the ransom note in a detailed manner. It asks the victims to write an e-mail to the hackers from the alternative e-mail address provided in the note in case they do not receive response from hackers in 24 hours. The e-mail must contain the unique ID (mentioned in ransom note) of the victim in the subject-line.
Hackers demand the ransom for decryption in Bitcoins, which solely depends on how quickly the victim is contacting the hackers. They promise to send the Wiki Decryption tool after receiving the ransom amount.
To display the authenticity of their promises, the hackers offer to decrypt any one file for absolutely no cost. However, the file sent for decryption should not contain sensitive information. This way the hackers attempt to earn the confidence of the victims.
Regardless of the claims made in the ransom-note, computer users are expressly advised not to communicate with the hackers & make any ransom payment. Victims not always receive necessary tools & unique private key in exchange of the ransom amount.
Analysis has revealed that majority of the victims who paid the ransom did not receive any response from the hackers. And sadly, they lost their data permanently.
Therefore, in order to protect the data from encryption or damage, computer users are advised to keep the data backup in remote servers &/or on unplugged storage devices.
