A DDoS mitigation service provider in Europe was targeted in a massive distributed denial-of-service attack that reached 1.5 billion packets per second.

The attack originated from thousands of IoTs and MikroTik routers, and it was mitigated by FastNetMon, a company that offers protection against service disruptions.

“The attack reached 1.5 billion packets per second (1.5 Gpps) — one of the largest packet-rate floods publicly disclosed,” FastNetMon says in a press release.
