How to Remove Cdpo Ransomware

Cdpo ransomware is a new edition of a virus emerging from the STOP/DJVU group. It uses a complex method of locking computer users out of important files like documents, spreadsheets, images, videos, drawings, archives, and so on. In fact, Cdpo ransomware is notorious because it can encrypt a long list of file types aside from the ones mentioned. Aside from encrypting the data, this ransomware incorporates a Cdpo file extension as a way to identify the affected objects. To cite an example, the usual image.jpg will transform into image.jpg.cdpo after the encryption process.

The primary objective of Cdpo ransomware

The main objective of the Cdpo ransomware virus is to encrypt the files on a victim’s computer or network, rendering them inaccessible. Once the files are encrypted, the ransomware displays a message demanding payment, usually in cryptocurrency, in exchange for the decryption key. The goal is to coerce the victim into paying the ransom to regain access to their files. Cdpo ransomware attacks can target individuals, businesses, or even entire government systems, seeking financial gain for the attackers. The perpetrators often threaten to permanently delete or publish sensitive data if the ransom is not paid, adding an additional layer of coercion to their malicious activities.

How Cdpo virus infects the computer?

There are dozens of ways for Cdpo ransomware to successfully infiltrate the computer. Social engineering attacks, web injections, Trojan Downloader infections, software exploits, and spam email messages are just the top spreaders of this virus. Among the stated methods, it was observed that mass-mailing is the most successful way to deploy Cdpo ransomware. This is a technique where the virus is attached to an email, and the attackers send it to randomly selected recipients.

When the attached file is opened, Cdpo ransomware starts the stages of attack that begin with communication to a remote server. Then, it downloads extra files on the infected computer as well as placing entries in the Windows Registry. The moment that it is operating perfectly on the infected computer, file encryption starts, and this is the most hazardous part of all the stages.

File encryption and decryption by Cdpo

The ransomware scouts the drive for target file types and encrypts them using a complex algorithmic method. This military-grade encryption process is difficult to decipher because a combination of the private key and tool is necessary for file recovery. Aside from the encryption process, the virus is going to append the encrypted data with a Cdpo file extension.

To be able to decrypt the files, the attackers are requesting payment from the victims. Even if the offenders ensure full recovery of files after the payment, there are reports of unsuccessful file decryption. Due to this, malware researchers do not recommend dealing with these cyber-criminals. According to them, victims should focus first on the removal of Cdpo ransomware and wait for the free and official decryption tool.
