Yanlouwang Ransomware

Yanlouwang Ransomware is malware that is in development, yet it is already causing concern for businesses. The group was discovered in August 2021 in one of its attacks. Yanlouwang is a name for a Chinese entity, known as the god of the underworld, Yanluo Wang. Although the name is derived from an Asian culture, there is no information on where the ransomware originated.

Despite being in testing stages, the ransomware was able to break into the systems of large institutions such as Walmart. In a post on the group’s leak site, they claim to have accessed about 40,000 to 50,000 Walmart computers. The hackers asked for $55 million to hand over the files, but the company ignored the negotiation and resorted to other methods to recover the data. Walmart denies such an attack.

The ransomware is not interested in stealing the victims’ files, but only in encrypting them using the RSA-1024 encryption algorithm. When systems are infected, all files are given the extension “.yanluowang” and if ransom demands are not met, threats of DDoS (Distributed Denial of Service) attacks are carried out.

According to Kaspersky, the countries that suffered most attacks from the group were the US and Turkey, both responsible for 20% of the victims, and Brazil with 16% of the targets. The ransomware operates in these countries targeting organizations in the finance, manufacturing, IT, consulting, and engineering sectors.

Ransomware Recovery FAQ

Every day, ransomware attacks get better and better. After a successful attack attempt, ransomware quickly maps the user’s most important files to begin encryption. Microsoft Office files, databases, PDFs and design are among its main targets.

Ransomware is designed to be unnoticeable, so it can disable all system defenses without being noticed and start the process of encrypting the files. Even though ransomware can go unnoticed by the system, it can still be noticed by the user, because ransomware uses the system’s own resources to do the encryption, this can slow down the system. Ransomware also changes file extensions. So be on the lookout for these signs: System slowdown and extensions being added to files.

You can also start the diagnostics to identify threats with your antivirus, the vast majority of antiviruses have this function.
