Demand:- After encryption, the ransomware will display a ransom be aware at the sufferer's display. This be aware commonly demands fee in cryptocurrency (consisting of Bitcoin) and presents instructions on the way to pay to acquire the decryption key.
Payment and Recovery:- If the victim decides to pay the ransom, there may be no assure that the attackers will offer the decryption key . In some Cases, paying the ransom can also inspire in addition assaults or result in additional needs.
Types of Ransomware
There are different types of ransomware each with its own methods of attack and effect are classified these are following:-
1. Crypto Ransomware :-
Crypto ransomware encrypts files on the Victim device. Common examples encompass WannaCry and NotPetya. Once the files are encrypted, they become inaccessible without the decryption key, and the victim is required to pay a ransom to regain access.

⮞ Anonymity of Payment:- The use of cryptocurrencies for ransom bills lets in attackers to remain anonymous, making it difficult for regulation enforcement to music them.
⮞ Sophisticated Techniques:- Modern ransomware makes use of advanced encryption techniques and evasion techniques to avoid detection by using traditional security measures.
⮞ High Pressure Tactics:- Ransomware regularly employs excessive-pressure approaches, together with countdown timers or threatening messages, to coerce victims into paying fast.

8. Network Segmentation
Segment your network to isolate essential structures and statistics. If an attack occurs, community segmentation can help incorporate the harm and prevent it from spreading in the course of your whole community.
9. Implement Multi-Factor Authentication (MFA)
Enable MFA(multi factor authentication) for all important systems and accounts. MFA calls for users to provide a couple of sorts of verification before gaining access, making it greater difficult for attackers to compromise accounts.
