ChaCha is a file-encrypting threat that uses two different ciphers (RSA + ChaCha20) to lock targeted data. The malicious activities of this cyber threat were spotted in the first have of May.

Payload

Transmission

ChaCha ransomware is a very dangerous and difficult threat due to the ways its activities are being carried out. It mostly gets carried through bundled free third party programs, spam emails, suspicious websites, shareware and other tricks.

Infection

once files are encrypted, ChaCha virus adds an extension which contains random characters. Additionally, the ransomware virus applies 0x66116166 mark to each encrypted component. Later on, the malware bombards the computer screen with a message named DECRYPT-FILES.html.

ChaCha targets English-speaking people because it produces a message in this language. English is first in the entire world so using this type of language is the easiest for crooks to communicate with there victims. Take a closer look at the ransom-demanding message:
