A campaign that uses trusted online advertising networks to deliver malware to users through ads?

• A. Hiberfil.sys
• B. Malvertising
• C. System Restore Points
• D. CCleaner

Answer: (B)

Malvertising is when attackers use legitimate online advertising networks to spread malware. Ads served through trusted networks and on reputable sites can carry malicious code or exploit kits that execute when the ad loads, sometimes even without the user clicking anything. This takes advantage of the user’s trust in the ad network and the site, making infections feel legitimate and harder to spot. The other options don’t describe a campaign that delivers malware via ads: a hibernation file is just a Windows system file, system restore points are for undoing changes, and CCleaner is a cleanup tool—none of these capture the scenario of malware being distributed through ads.
