All of the following can be indications of a ransomware attack EXCEPT?

Ransomware attacks are typically characterized by certain signs, including:

Inability to access certain files (Option A): This is a primary indication as ransomware often encrypts

files, making them inaccessible.

Increased CPU activity for no apparent reason (Option C): This can be a sign of encryption processes

running in the background.

Detection of suspicious network communications (Option D): Ransomware often communicates with

command and control servers for instructions or to send encryption keys.

Option B, an increased amount of spam email, is not an indication of a ransomware attack. Spam

emails are more commonly associated with phishing attacks or general email security issues.
