• C. Ransomware attack

Answer: (C)

A corporation finding a note demanding cryptocurrency for a decryption key is experiencing a ransomware attack. This type of cyber threat involves malicious software that encrypts the victim's data, rendering it inaccessible. The attackers then demand payment, often in cryptocurrency, to provide the decryption key, which is necessary to regain access to the compromised files.

Ransomware typically spreads through various means, such as malicious email attachments or compromised websites. Its primary goal is financial gain for the attackers, and it can have devastating effects on businesses, potentially leading to significant data loss and operational interruptions. Recognizing ransomware is crucial for organizations to develop effective strategies for prevention and recovery.
