What is Arena virus?

Arena virus is the name of a computer virus categorized as Dharma ransomware. The Arena virus infects a computer, encrypts files that match certain files types using military grade cryptography algorithms, and appends the .arena file extension (.id-[ID].sindragosa@bigmir.net].arena) to the end of the file name. The ransomware will also download a ransom note named FILES ENCRYPTED.txt in each existing folder and Windows desktop.

Once the Arena virus has encrypted certain files such as video, image, document, and others it will download a ransom note on Windows desktop and in folders it encrypted files in. The Arena virus uses the ransom note to explain to victims of the virus what happen to their files and how to purcahse a decryption key and special tool to decrypt files the way that the malware authors want them to. The ransomware suggests to email sindragosa@bigmir.net for information and help.

An example of the content from the actual ransom note is detailed below (typos are correct):

Like most ransomware infections, the Arena virus is typically spread by email spam messages that contain malicious .zip and .rar email attachments. Once the attachment is downloaded and executed it will spread the malware across the machine and begin its encryption process.
