Botnets on Your Network: Detection and Clean-up for ISPs
Infected subscriber devices damage your reputation and bandwidth. Here is how ISPs detect and remediate botnet activity.
How botnets hurt ISPs
Compromised routers, cameras and PCs launch DDoS attacks, send spam and scan the internet. The result is blacklisted IP ranges, abuse complaints and wasted upstream capacity.
Detection signals
- Connections to known command-and-control infrastructure
- Sinkhole and threat-intelligence feed matches
- Unusual outbound scanning or SMTP volumes
- DNS lookups for algorithmically generated domains
Remediation that works
Notify affected subscribers clearly with simple steps — reboot, update firmware, change default passwords. For repeat cases, a walled-garden approach that limits access until clean-up is effective.
Prevention
Ship customer premises equipment without default passwords, enable automatic firmware updates and block common abused services at the edge where appropriate.
