Crypto Locker is a form of which of the following?

Correct option is A

CryptoLocker is a type of ransomware, a malicious software designed to encrypt a user's files and demand a ransom payment in exchange for the decryption key. It was first observed in 2013 and became infamous for targeting individuals and businesses, causing significant data loss and financial harm.

Important Key Points:

1. Ransomware like CryptoLocker encrypts critical files, making them inaccessible to users.
2. Victims are typically asked to pay in cryptocurrency, such as Bitcoin, to regain access to their data.
3. Regular backups and robust security measures are essential to mitigate the risks of ransomware attacks.

Knowledge Booster:

• Adware: Software that displays unwanted advertisements, not related to file encryption or ransom demands.
• Spyware: Malicious software that secretly gathers user information without encrypting files.
• Worms: Self-replicating malware that spreads across networks but does not involve encryption or ransom demands.
