Malvertising, or malicious advertising, refers to the use of online advertisements to spread malware. Cybercriminals inject malicious code into ads, which can then infect devices when users view or click on these ads. This tactic exploits legitimate advertising networks, making it difficult for users to identify harmful ads.
Malvertising can lead to various cyber threats, including data breaches, identity theft, and system compromises.
To protect against malvertising, users should keep their software updated, use ad blockers, and exercise caution when interacting with online ads.
