Malvertising

Definition

Malvertising refers to malicious advertising that uses online ad networks to spread malware. By embedding harmful code in legitimate online advertisements, cybercriminals can distribute malware without needing direct interaction from users. This technique often exploits trusted websites, making it harder for users to detect the threat and increasing the chances of infection.

Review Questions

• How does malvertising utilize legitimate advertising networks to spread malware?
  • Malvertising takes advantage of trusted online advertising networks by embedding malicious code within ads that appear on reputable websites. When users view or click on these ads, they unknowingly download malware onto their devices.

  • Current strategies to combat malvertising include using advanced threat detection systems and implementing strict vetting processes for advertisers. Ad networks are increasingly focusing on identifying and removing malicious ads before they reach users. However, the effectiveness of these measures varies as cybercriminals continuously evolve their tactics to bypass detection systems. Ultimately, while strides have been made, ongoing vigilance and user education remain essential components in reducing the risks associated with malvertising.
