How Ransomware Works
Infection:

Ransomware is often delivered through phishing emails, malicious downloads, or software vulnerabilities.
Once activated, the malware spreads through the system or network.
Encryption:

Files and systems are encrypted using strong cryptographic algorithms, making them inaccessible to the victim.
Ransom Demand:

A ransom note is displayed, demanding payment in cryptocurrency (e.g., Bitcoin) to decrypt the files.
Decryption (Optional):

If the victim pays the ransom, the attackers may (but not always) provide a decryption key.
Types of Ransomware
Crypto Ransomware:

Encrypts files, making them inaccessible.
Examples: WannaCry, Locky.
Locker Ransomware:

Locks the user out of their device entirely.
Example: Reveton.
Double Extortion Ransomware:

Encrypts files and threatens to release sensitive data if the ransom is not paid.
Example: Maze.
Ransomware-as-a-Service (RaaS):

A subscription-based model where attackers rent ransomware tools.
Example: DarkSide.
Famous Ransomware Attacks
WannaCry (2017):

Affected over 200,000 computers in 150+ countries.
Targeted Windows systems, exploiting the EternalBlue vulnerability.
Impacted hospitals, government agencies, and businesses worldwide.
NotPetya (2017):

Disguised as ransomware but acted as a destructive cyberattack.
Originated in Ukraine and spread globally, affecting shipping, healthcare, and finance.
Colonial Pipeline Attack (2021):

Demands often exceeded $70 million.
SamSam (2018):

Targeted healthcare and government institutions.
Attackers demanded payments of up to $64,000 per victim.
Preventing Ransomware Attacks
Regular Backups:

Maintain offline and cloud backups to restore data without paying the ransom.
Update Systems:

Regularly patch software and operating systems to close vulnerabilities.
Use Security Tools:

Install antivirus and anti-ransomware tools.
Employ firewalls and intrusion detection systems.
Educate Users:

Train employees to recognize phishing emails and avoid clicking suspicious links.
Zero Trust Model:

Restrict access to sensitive data and systems on a need-to-know basis.
