I was logged into my Cloudflare account today attempting to setup Tunnels when I noticed various security events related to my domain. Upon further inspection I realized that they all originated from a Microsoft Owned IP address (I’m assuming somebody running a Azure VM instance).
Looking into the actual request headers I can see that whatever bot was running was looking for common PHP exploits or unsecured endpoints.
I usually ignore such instances as I have proper firewall rules both on the Cloudflare side as well as my local network side so I’m doubting there’s actually any threat to my network. However, I decided today to email the abuse contact provided from the WHOIS details. Was wondering if anybody else had experience with writing these? Is it even worth writing them or do they just end up being a waste of time?
Edit: Thanks everybody for the responses! Seems that it’s up in the air if I’ll ever get a response back. Maybe that’s okay - Looks like the general consensus is that these usually do end up getting taken seriously (at least by some providers). I guess I’ll keep composing away even if it’s just an exercise in good internet stewardship :)
Wait, what? To their [email protected] or whatever email (whatever’s listed in whois)?
I’ve had Azure IPs absolutely hammering my VoIP server and absolutely none of the reports I sent were even acknowledged. Ended up just blocking the entire Azure CIDR range in the firewall.
AWS, OTOH, got back to me within about an hour and a resolution within 3.
Yep! Just for whatever the abuse contact was in whois. Could have been coincidence, or maybe just whoever was on shift in Azure town at the time. I don’t remember if I got a response or not from MS.
