Rumba is a high-risk computer infection categorized as ransomware. It is a new variant of Djvu ransomware and was discovered by Michael Gillespie. Programs of this type are designed to encrypt data (rendering it unusable) and keep it in that state unless a ransom is paid. To retrieve their files, users are encouraged to purchase a decryption tool. After encryption, all files are renamed by adding the “.rumba” extension. For example, “1.jpg” becomes “1.jpg.rumba”. Instructions about how to decrypt files can be found in the “_openme.txt” text file.
