What is Ransomware?

What is Ransomware?

Ransomware is a new generation threat that uses a strong Encryption algorithm that encrypts the some or all your computer files.

Hackers use Phishing Emails, RDP vulnerabilities and cracked software in order to enter your infrastructure.

Then they launch the encryption trojan to lock your files while the malicious hacker has they only key to the decryption.

The Ransomware reseller or controller, after all your files are encrypted, asks you to pay a ransom payment in order to decrypt your files.

Sometimes you will be blackmailed not only to pay once but many times in order to get your files

Ransomware teams are ruthless and will try to extort as much money they can from you, in the form of bitcoin or other cryptocurrencies.

Sometimes they demand huge amounts and even when they get paid, they ask for more.

You can never be sure.

Also sometimes they give you a certain timeframe where you need to pay and if you don’t they double the price.

But even if you don’t pay, they will blackmail you that they will release your data to the public.
