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 FortectIntego.
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. While we do not believe that this virus is going to be distributed actively, other cybercriminals can use it as a base to create their customized ransomware viruses. 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. If you want to protect your files, create data backups. Learn how to create them now.
Remove DUMB ransomware with ease
If you want to remove DUMB virus easily, just run the anti-malware software and let it clean the computer system from malware and spyware for you. Before DUMB removal, close the program to restore your files. This method is not going to work in case you’ve been infected with Ransomeer ransomware. If so, you should use data backups or data recovery methods provided below to restore your files.
