Hi Joe & Joe, I’m not sure which Joe is the original Joe anymore, but I like this reply better than the previous one. It feels more informative and more useful to the community. I just stumbled on this article. https://www.zdnet.com/article/google-chrome-syncing-features-can-be-abused-f... Could it be that what the OP observed is link to a browser vulnerability started to be exploited recently?

I would think (at a minimum) you would be able to negotiate such an action with them, perhaps it is time to re-negotiate that contract? If your simply trying to report an offending IP for brute force stuff perhaps the tact you may find more helpful is to ask for a contact at xzy ISP on list, versus asking folks to do reporting for you. As well there are like 100s of lists to report this to outside of NANOG As well, if I am reading this correctly, deployment of devices that have public facing IPs and do not have a means to protect themselves is concerning to say the least. This is about as reckless as putting up a login page without a password and crying foul when something gains access that you didn't expect. Again, I do not know all of the details of this so I may be way off base with that respect. If your ability to prevent issues is due to lack of a firewall/control to your network, possibly asking for help in mitigating such threats would be better, as there are a lot of very well versed/clever folks that help out.

I stated we have a plan but it is ways out. FACT: we have a known malicious C&C FACT: We know what networks it is hitting and the cellular network is the most vulnerable, imo. FACT: this IP is against Verizon terms of service so the way to address it is to report it to them as they request. I honestly got what I needed from this thread, thanks. And I thank the nonbullies that helped me off list. -- Thank You, Joe On Thu, Feb 4, 2021 at 5:11 PM Ryan Hamel <administrator@rkhtech.org <mailto:administrator@rkhtech.org> > wrote: Joe, It isn’t on Verizon to setup a firewall, especially if you have a direct public IP service. The device being attached directly to the Internet (no matter the transmission medium), must be able to protect itself. ISPs provide routers which function as a NAT/Firewall appliance, to provide a means of safety and convenience for them, but also charge you a rental fee. Stick a Cradlepoint router or something in front of your device, if you want an external means of protection. Otherwise you’ll need to enable the Windows Firewall if it’s a Windows system, or setup iptables on Linux, ipfw/pf on *BSD, etc. Ryan From: JoeSox <joesox@gmail.com <mailto:joesox@gmail.com> > Sent: Thursday, February 4, 2021 5:04 PM To: ryan@rkhtech.org <mailto:ryan@rkhtech.org> Cc: TJ Trout <tj@pcguys.us <mailto:tj@pcguys.us> >; NANOG <nanog@nanog.org <mailto:nanog@nanog.org> > Subject: Re: Suspicious IP reporting How do I setup a firewall when I am not a Verizon engineer? There is a firewall via the antivirus and operating system but that's it. Do you not understand my issue? I thought that is the real problem with the online bullies in this thread. -- Thank You, Joe On Thu, Feb 4, 2021 at 5:01 PM Ryan Hamel <administrator@rkhtech.org <mailto:administrator@rkhtech.org> > wrote: Joe, The underlying premise here is, “pick your battles”. If you don’t want an IP address to access your device in anyway, setup a firewall and properly configure it to accept whitelisted traffic only, or just expose a VPN endpoint. The Internet is full of both good and bad actors that probe and scan anything and everything. While some appreciate the notification here, others will find it annoying. We cannot report anything malicious about an IP address on the Internet, unless it does harm to us specifically, otherwise it is false reporting and does create more noise at the ISP, and waste more time getting to the underlying issue.
