Ransomware Summary
- Ransomware is a type of malicious software that encrypts a victim’s files.
- Attackers demand a ransom payment to restore access to the encrypted data.
- It often spreads through phishing emails, malicious downloads, or network vulnerabilities.
- Ransomware attacks can target individuals, businesses, and governmental institutions.
- Paying the ransom does not guarantee data recovery, and it encourages further attacks.
Ransomware Definition
Ransomware is a type of malicious software designed to block access to a computer system or data until a sum of money is paid. It typically encrypts the victim’s files, making them inaccessible, and demands a ransom payment for the decryption key.
What Is Ransomware?
Ransomware is a form of cyberattack where malicious software encrypts a victim’s data.
The attacker then demands a ransom payment, often in cryptocurrency, to provide the decryption key.
The primary goal is to extort money from the victim.
Who Is Targeted By Ransomware?
Ransomware can target anyone with digital data.
This includes individuals, small businesses, large corporations, and governmental institutions.
Attackers often target entities that are more likely to pay the ransom, such as hospitals or financial institutions.
When Did Ransomware Become Prevalent?
Ransomware attacks have been around since the late 1980s.
However, they have become more sophisticated and widespread in the past decade.
The rise of cryptocurrencies has facilitated anonymous ransom payments, leading to an increase in attacks.
Where Does Ransomware Spread?
Ransomware can spread through various vectors.
Common methods include phishing emails, malicious attachments, drive-by downloads, and exploiting network vulnerabilities.
It can affect any system connected to the internet, from personal computers to enterprise networks.
Why Do Attackers Use Ransomware?
Attackers use ransomware primarily for financial gain.
By encrypting critical data and demanding a ransom, they create a sense of urgency and desperation in the victim.
The anonymity provided by cryptocurrencies makes it an attractive method for cybercriminals.
How Does Ransomware Work?
Ransomware typically starts with an initial infection, often through a phishing email or malicious download.
Once on the victim’s system, it encrypts files and displays a ransom note.
The note instructs the victim on how to pay the ransom, usually in cryptocurrency.
After payment, the attackers may or may not provide the decryption key.
