Making the victim focus on service restoration while stealing data
Which scenario best exemplifies a Denial-of-Service attack mentioned in the text?
An individual causing service unavailability by pulling a power switch
What is highlighted as an often misperceived aspect of Denial-of-Service attacks in the text?
The belief that they always involve sophisticated cyber tools
In the context of Denial-of-Service, what could be a potential reason why an attacker might target a DNS server specifically?
