Summary
Attackers route malicious traffic through ordinary home internet connections — and to a reputation feed, the source IP is indistinguishable from a legitimate user's connection. GreyNoise analyzed 4 billion sessions over 90 days and found that 39% of unique IPs targeting the edge come from residential address space. 78% vanish after just 1–2 sessions, before any reputation system can flag them. The report documents why detection must shift from where the traffic comes from to what it is doing.
