DUMB ransomware project: everything you need to know about this virus

Authors of the DUMB virus must be very sarcastic. They have not only dubbed the ransomware “dumb,” but also asks victims to pay a ransom of 100 didgeridoos to restore encrypted files[1]. Speaking about the encryption, the virus uses XOR pad [2] generated via the ISAAC CSPRNG. What is more, while many viruses cannot encrypt large files, DUMB virus easily encodes files larger than 4GB in size. However, files can be decrypted in a surprisingly easy way. The victim simply needs to close the “Main” program that DUMB ransomware launches. This program says that victim’s files have been encoded, and in 48 hours the key to decrypt files will be deleted unless the victim deposits “100 didgeridoos in a private didgeridoo wallet.” Not sure what the criminals wanted to say because [[3] is a wind instrument created by Indigenous Australians.

This virus has been developed by Alfur, a member registered under AlphaDelta nickname of GitHub. This ransomware is created using C# programming language[4] and is described as a fast ransomware proof of concept[5]. While it appears that this ransomware was developed for fun, cybercriminals quickly scrapped the code of this ransomware and built Ramsomeer virus based on it. This virus provides an identical user interface, but it provides the information not only in English but in the Turkish language as well. Ramsomeer malware wants to get 0.3169 Bitcoins in exchange for the decryption key, and just like common ransomware viruses, it leaves a Bitcoin wallet address so that the victim could transfer the ransom to it. This version is definitely more dangerous. If you have been attacked by Ramsomeer ransomware, we are afraid that it might be impossible to restore your files (unless you have a backup). Speaking about DUMB ransomware, all you need to do is to close the ransomware window to decrypt your records. We have written instructions on how to remove DUMB ransomware successfully – do not forget to read them before running anti-malware software to clean your PC from malware. We suggest you complete DUMB virus removal using trustworthy anti-malware tools like Reimage.

Learn how ransomware viruses spread

DUMB ransomware project is unlikely to expand its extent because it seems that it was developed as a proof of concept.

Therefore, you need to know what methods scammers use to distribute malicious programs. In general, ransomware viruses are mostly distributed via email, exploit kits, and malware-laden ads. To avoid getting infected with ransomware via email, you should stay away from suspicious-looking emails that contain attachments. To avoid ransomware attacks via exploit kits and malware laden ads, stay away from untrustworthy websites online and protect your PC with proper security tools.
