Does AiProtection really work?

Good to know about the Russian connection. AG started acting weird on my router recently, so I went back to Diversion. AG is fun to play around with, has great reporting & logging. Diversion has much of the same, seems to integrate better w/ Merlin, and other features found in AG can be configured on other parts of the router, like assuring that the router is the exclusive provider of DNS by blocking 53, 853, 80/443 UDP & so on (DNS Director works and then doesn't). Diversion has it's quarks, but generally seems to be stable.

AIProtect, I believe over the last few months with the news about Asus routers having certain CVEs I found that one of the functions of the IDS/IPS portion is to prevent those vulnerabilities from being exploited on the router--if you haven't updated or receive a new device that may have been on the shelf for a while. If you decide to turn AIProtect off then you might not have protection and should probably be sure to update your router anytime an update is released...

On another note, I wanted to see what the AIProtect option in Skynet was about--to see what entries would be added when you select "Add AIProtect Data". I had ClaudeAI put together a script. As far as I can tell it doesn't make any external calls or run outside of its' lanes (only pulls the sql data and formats it). The attached script, I placed in my /jffs/scripts folder. After running the script, the database really doesn't have all that much information in it other than what's easily found in the WebGUI.. There's an option to export that data into a report, however I haven't tried that menu option.... Thought I would upload it, in case someone is interested. YMMV as it has only been tested on an AX86u, so you may have to make adjustments to the script for it to work & a "chmod +"? once you save it.... In other words, I currently don't have the time to support it, however if you want to see what's in the AIProtect database this does that and a little more...

if you haven't updated

The signatures file AiProtection uses updates infrequently. Chances to catch something new are slim.

My signatures are dated January 2025 and no updates since then doing manual updates.

I support a few Asus routers remotely, the signature file shows version 2.464 from Jul 2025.

Yes that's the same version # I have and it never has updates since January 2025. Thank you for responding!

Adguard is Russian. It seems to always be the one complaining in logs about DNS rebind security issues when I tried a couple of years ago using their DNS resolvers.

1. I use Cloudflare's Family DNS over TLS, with DNS Sec. Cloudflare Family does Malware and Adult. Remember, many adult sites and adverts on them are booby trapped in terms of malware.
2. Validation of unsigned DNSSec replies
3. DNS rebind protection enabled.
4. I use Microsoft's Smartscreen and Defender on Windows PCs.
5. Windows PC's locked down further by group policies and disabling of non important services (like telemetry)
6. Auto Update enabled on other family member devices.
7. On windows, remove some components not required by DISM (e.g. Windows Recall).
8. Android and Apple devices configured to be more secure than default by disabling any "leakage" of data where possible.
9. No old protocols in use like SMB v1 on any device.
10. WPA3 and MAC filtering (yes, MAC filtering is not absolute, just another step to make it harder for casual)
11. Long SSID passkey with complex characters and non-dictionary words
12. Isolate WiFI devices from other VLANS / Intranet
13. All devices must use the DNS over TLS as it's set to force on Asus router.
14. AI Protection is ON and caught stuff on a regular basis, mainly, but not limited to, things like adverts being a scam.
15. I use Diversion and LARGE list for Ad blocking.
16. DoS enabled on routers and switches (my switches are managed types).
17. WiFi devices over SharkSurf VPN at router level.
18. VLANS setup on router (GT-BE98)
19. Machines/Switches and software are patched.
20. Any web facing servers behind reverse proxy and Cloudflare (free) as two stage certs between host and clients and hides home IP. Most security options enabled there.
21. Client Outlook configured to block any countries deemed not required for emails (UK/Eire/US/Australia/NZ/Europe OK but others not so)
22. SkyNet block certain countries unlikely to ever visit their URLS (North Korea etc)
23. Review of privacy and security options at Google and Microsoft including setup of 2FA.

Defence in Depth for me. Just some of the stuff I've done.

Is ad blocking in your list?

Like all other upstream filtering services returning 0.0.0.0. It's an old Russian DNS rebind trick.

Just some of the stuff I've done.

Won't hurt to learn what some of the stuff on your list does and how. It's close to "how to torture my family members better with what I found on Internet" category. Completely unrelated to the original question about AiProtection.

Thanks, I should have seen that.
