+42%
year-over-year increase in malvertising campaigns
Security vendors reported a 42% year-over-year jump in tracked malvertising campaigns, where legitimate ad networks deliver malicious payloads to unsuspecting users.
Context
Malvertising is the strongest security argument for ad blocking: even reputable sites have unknowingly served drive-by downloads, fake browser update prompts and tech-support scams via their ad slots.
Key takeaways
- Ad blocking is also a security control, not just a comfort tool.
- Enterprise security teams increasingly recommend ad blockers as endpoint hardening.
