A smart-home camera maker ships devices with a default password that users are never prompted to change. Attackers log in to thousands of cameras and use them to flood a website with traffic. Which pairing correctly describes the weakness and the resulting attack?

The weakness is weak, unchanged default credentials, and the attack is a distributed denial of service. Hijacked cameras form a botnet that floods the target website with traffic, a well-known pattern in IoT security failures.

  1. AWeak default credentials; distributed denial of service via a botnetCorrect
  2. BStrong encryption; phishing of bank customers
  3. CUnpatched mainframe; ransomware on paper records
  4. DExcess bandwidth; SQL injection on the camera screen

Explanation

Unchanged default passwords are a classic IoT weakness that lets attackers take over devices. Compromised devices form a botnet used for a distributed denial of service attack, as in the Mirai incident. The other pairings do not match the facts.
