AI Penetration Testing Tools: The Unintended Consequences of Out-of-Bounds Scanning
Artificial Intelligence is rapidly transforming how we manage network security. Recently, a growing number of web design agencies, developers, and system administrators have started utilizing new, AI-driven penetration testing and vulnerability scanning tools to audit their server environments. While we always encourage taking a proactive approach to your security here at Big Wet Fish, we are seeing a concerning trend: these AI tools are frequently probing outside of their intended scope.
If you are using or planning to use automated AI security tools on your Big Wet Fish hosted environments, it is crucial to understand how they operate and how our upstream network perimeter defenses will react to them.
The Problem: "Wandering" AI Scanners
Traditional penetration testing tools require strict parameter definitions. You tell the tool exactly which IP addresses or domains to target, and it stays strictly within those boundaries. However, some of the newer AI-assisted tools on the market attempt to be "smart" by automatically mapping network topologies. In doing so, they often scan neighboring IP spaces or probe the core routing and firewalling infrastructure of our data center partners.
From a network security perspective, there is no difference between an AI tool inadvertently probing neighboring IP addresses and a malicious actor actively searching for network vulnerabilities. Both look exactly like aggressive port scanning.
How the Network Edge Defenses React
At Big Wet Fish, we manage our own IP address schemes and internal firewalling to give you the flexibility you need. However, our upstream data center provider (Husky Networks) employs robust, dynamic edge filtering to protect the core data center infrastructure and the wider network ecosystem from unsolicited traffic.
When an AI tool begins scanning IP addresses outside of the hosting environment you control, the intrusion detection systems (IDS/IPS) immediately flag the activity.
Here is what happens next:
* Automated Perimeter Drops: Traffic exhibiting network scanning patterns targeting the data center's core infrastructure or unallocated IP space is automatically dropped at the network edge.
* The 24-Hour Block: To mitigate the perceived threat, the source IP address conducting the scan is placed on an automated blocklist, typically for 24 hours.
* Loss of Access: Because this block is applied at the outer perimeter of the data center, the offending source IP is prevented from reaching any address within the network. This means you will instantly lose connectivity to your own legitimate Big Wet Fish servers and services.
A Note on Accountability and Investigations
Recently, we have had a number of clients who have been somewhat economical with the truth after getting themselves blocked by these edge defenses. Denying involvement, withholding information, or framing an automated security drop as a mysterious "network outage" triggers unnecessary, multi-hour investigations by our support staff and our data center's network engineering team. We therefore ask you tell is exactly what you were doing if you get blocked.
If your IP address is blocked due to out-of-bounds scanning resulting in wasted time and diagnostic resources to track down a self-inflicted issue we will bill you for the engineering and support time wasted during the investigation. Honesty and transparency will save everyone time, money, and frustration.
Best Practices for Automated Security Testing
We are fully committed to ensuring a secure and stable environment for all our clients. To prevent automated edge blocks and ensure your testing doesn't impact your connectivity, please follow these best practices:
* Define Strict IP Scopes: Before initiating any AI-driven or automated penetration test, double-check the tool's configuration. Ensure it is strictly hardcoded to only scan the specific IP addresses assigned to your servers.
* Disable Auto-Discovery: If your tool has an "auto-discovery," "network mapping," or "lateral movement" feature, disable it unless you are conducting a test on a strictly isolated, local network that you entirely control.
* Know Your Boundaries: Scanning infrastructure that you do not own or manage—including the data center's core routing hardware or neighboring client IP spaces—is a violation of standard network policies and will always trigger defensive countermeasures.
By ensuring your security tools are properly scoped, you can keep your server environments secure without inadvertently triggering network-wide defense mechanisms. If you have any questions about how your specific testing methodology might interact with the network's edge defenses, please open a ticket with the Big Wet Fish support team for guidance before you begin testing.
