What best describes a web cache poisoning attack?

• A. Intercepting data packets
• B. Replacing stored data with malicious content
• C. Searching through hard drives for vulnerabilities
• D. Logging keystrokes on user devices

Answer: (B)

A web cache poisoning attack is characterized by the manipulation of the web cache by injecting malicious content into the cache store, replacing the legitimate data that would typically be served to users. This technique exploits the way caching systems operate, where cached responses are reused to serve multiple users without having to access the original server each time. When an attacker successfully poisons the web cache, future users requesting the same resource may unknowingly receive the harmful content instead of the intended, safe content. This can lead to various negative outcomes, such as users downloading malware, getting redirected to malicious sites, or having their data compromised. The other options do not adequately describe web cache poisoning. Intercepting data packets typically refers to man-in-the-middle attacks, which do not inherently involve caching. Searching through hard drives for vulnerabilities is more aligned with local security assessments, and logging keystrokes pertains to keylogging, which is a different form of attack targeting user devices rather than web cache systems.
