Cloudflare has a new feature—available to free users as well—that uses AI to generate random pages to feed to AI web crawlers: Instead of simply blocking bots, Cloudflare’s new system lures them into a “maze” of realistic-looking but irrelevant pages, wasting the crawler’s computing resources. The approach is a notable shift from the standard block-and-defend … Read More “AI Data Poisoning” »

The widely reported story last week that 1.5 million smart toothbrushes were hacked and used in a DDoS attack is false.

It was a hypothetical, which Fortinet … Read More “No, Toothbrushes Were Not Used in a Massive DDoS Attack” »
