What is Diavol Ransomware?
In a warning issued by the Government of India, Diavol is a new strain of ransomware, transmitted to the Windows PC via email attachments containing URL links to OneDrive.
The ransomware, once installed, shuts down the device and demands a ransom to give back the control. It encrypts files and renames them .lock64 extension. Furthermore, it changes the desktop wallpaper and generates a README_FOR_DECRYPT.txt file containing data recovery information.
In addition to this, to scare users in the .txt file, hackers have mentioned that in absence of no payment their downloaded data will be published on the website controlled by the hackers.
Why is ransomware dangerous?
Unlike malware, virus, adware, and other malicious threats, ransomware along with stealing your data also decrypts it and kicks the victim out of the system. This means to get back access to data, the victim needs a decryption key which can only be retained after paying the ransom. However, if you don’t want to pay the ransom, then the only way to access data is by restoring the backup.
Note: Even if you pay the ransom, there is no guarantee that you will get the key. Therefore, paying cybercriminals is never recommended.
How ransomware infects the system?
Ransomware is distributed via malicious attachments sent in an email, product download from unreliable sources, software cracking tools, fake updaters, and opening malicious files. To trick users into opening such emails, cybercriminals often disguise them as a legitimate program or send them using employees or CEO ID that they have hacked.
