A bumper ad is a short, non-skippable video advertisement, typically lasting up to 6 seconds. These ads are commonly used on video platforms like YouTube to deliver concise marketing messages before the main content plays. In cybersecurity, bumper ads can be relevant because malicious actors may exploit such ad formats for phishing or malware distribution if ad networks are not properly secured. Organizations should ensure that their digital advertising partners follow strict security protocols to prevent malicious content from being delivered through bumper ads.
