Bitcoin ransomware CryptoWall continues to upgrade

Bitcoin ransomware is an emerging malware that attacks computers and networks around the world. Attackers have found a new way to illegally obtain Bitcoins by encrypting users' important files and forcing them to redeem them with Bitcoins. Even as developers continue to come up with ways to combat Bitcoin ransomware, the CryptoWall Trojan is constantly being upgraded, and new versions of Bitcoin ransomware are threatening users' Bitcoin security.

CryptoWall 4.0 is still extorting Bitcoin from users

,

Unfortunately, the latest version of CryptoWall ransomware does not remove the option to make infected users pay in Bitcoin. In fact, the latest version has been "improved" in many places and has better design specifications, which makes it more deadly than previous versions. The latest version of CryptoWall first appeared in November 2015, and then it became part of the hacker's核开发组件. For those who have not heard of this name before, the core exploit kit is one of the most powerful exploit kits in the underground hacker market.

In the past, CryptoWall was spread through traditional means, such as through phishing emails and spam. Despite the warnings issued by security experts every year, users can still get infected by opening unknown malware and ransomware. Since hackers can infect computers through kernel exploit components, CryptoWall 4.0 is more dangerous than before.

There is still a chance that hackers can install CryptoWall 4.0 on computers running Windows operating systems. Windows is the most widely used system in the world, which provides a lot of attack opportunities for CryptoWall 4.0.

CryptoWall 4.0 is very different from its previous versions. The previous versions encrypted individual files, while CryptoWall 4.0 also encrypts the file name itself. Once the computer is infected with this latest version of ransomware, the user has no choice but to pay Bitcoin or format the computer.

Impact on Bitcoin’s public image

Although Bitcoin has nothing to do with the CryptoWall ransomware attack, this series of attacks on Bitcoin has seriously affected the public image of digital currency. Media reports always exaggerate how unsafe Bitcoin is and how hackers use it to carry out various malicious activities around the world. In short, it is always good to be involved in hacker activities.

However, the inventors of CryptoWall and users mistakenly believe that Bitcoin ransom is anonymous, and they think that no one can trace its recipient. But Bitcoin is by no means anonymous, and anyone in the world can trace the final address of a Bitcoin transaction.
