Ransomware is a type of malicious software (malware) that encrypts a victim's data, files, devices, or systems, rendering them inaccessible and unusable until a ransom is paid to the attackers. Here's a concise explanation:

1.Definition

Ransomware is a form of malware that encrypts files and documents on various devices, from individual computers to entire networks, making the data inaccessible.

2.Modus Operandi

Ransomware typically enters a system through malicious email attachments, software vulnerabilities, or by exploiting security weaknesses.

3.Encryption

Once inside, it encrypts the victim's data using a strong encryption algorithm, making it impossible to access without the decryption key.

4.Ransom Demand

Attackers then demand a ransom, usually in cryptocurrency, in exchange for the decryption key. Paying the ransom is discouraged as it doesn't guarantee data recovery.

5.Impact

Ransomware attacks can have severe consequences, including data loss, financial damage, and potential harm to an organization's reputation.

It's crucial to implement strong cybersecurity measures, regularly back up data, and stay informed about evolving ransomware threats to prevent and respond effectively to these attacks.
