What is CONTI Ransomware

CONTI is a ransomware-type virus that encrypts user’s data and keeps it locked until the ransom is paid. Some security experts indicate, that it can be a successor or Ryuk Ransomware. Whilst the encryption is being made, all files including photos, videos, documents, and other regular data will be altered with the new .CONTI extension. This means that the affected files will look like 1.mp4.CONTI or similarly depending on the original name. After this, successful encryption is followed up with a text file (CONTI_README.txt) that is dropped on the desktop of victims.

CONTI Ransomware
Your system is LOCKED. Write us on the emails:
mantiticvi1976@protonmail.com
fahydremu1981@protonmail.com
DO NOT TRY to decrypt files using other software.

The note itself does not contain anything extraordinary, it simply says that your data was locked, and to decrypt it, you should contact cyber criminals via attached e-mails. It is also claimed that third-parties software will not seal the deal and might lead to permanent loss. It is partially true because ransomware developers create self-destruction mechanisms against the involvement of extraneous impact. For the moment, it is almost unreal to decrypt your files for free with the help of additional tools. If possible, you can restore your data from backup storage that was created before the infection. Either way, we recommend you to get rid of CONTI Ransomware to prevent further encryptions.

How CONTI Ransomware infected your computer

When it comes to ransomware infiltration, extortionists abuse e-mail spam with malicious attachments. They send these messages to random users and force them to open contained links or files (MS Office documents, PDFs, executables, and JavaScript files). If done, your system will be infected in the background mode without your consent. To prevent this, you should avoid clicking on suspicious content and downloading software from unwanted resources. It is also worth installing some anti-malware utilities to reinforce the shield against malware attacks. Besides that, there are other distribution channels like backdoors, keyloggers, trojans, exploit of unprotected RDP configuration, fake software cracking tools, and others.
