Summary
A comprehensive analysis of benign internet scanning activity from November 2024, examining how quickly and thoroughly various legitimate scanning services (like Shodan, Censys, and others) discover and probe new internet-facing assets. The study deployed 24 new sensors across 8 geographies and 5 autonomous systems, revealing that most scanners found new nodes within 5 minutes, with ONYPHE leading in first contacts.
