# Q-Feeds: ASNs with the highest confirmed malicious share # https://qfeeds.com/threat-statistics/malicious-asns/ # Updated 2026-10-13. Refreshed monthly from the Q-Feeds threat intelligence database. # Ranked by confirmed share: indicators reported by two or more independent sources, # discounted for cloud address space, minimum 70% and 50 malicious IPs in 90 days. # Not a block list: blocking a whole ASN also blocks its legitimate users (false positives). # Use it as a scoring or alerting input. # License: CC BY 4.0, attribution to Q-Feeds (qfeeds.com).
