Which of the following security threats aims to compromise a website that multiple employees frequently...

The best answer is C. Watering hole .

A watering hole attack occurs when attackers compromise a website that a targeted group commonly visits. The attacker expects the victims to access that site as part of their normal behavior, allowing malicious code or exploits to be delivered indirectly.

This exactly matches the scenario of a website that multiple employees frequently visit .

Why the other options are incorrect:

A. Supply chain A supply chain attack targets vendors, providers, or trusted third parties to affect downstream victims.

B. Typosquatting Typosquatting involves fake lookalike domains designed to trick users who mistype a web address.

D. Impersonation Impersonation involves pretending to be a trusted person or entity, not compromising a commonly visited site.

From a SY0-701 perspective, compromising a trusted site used by a target group is the definition of a watering hole attack.
