Alight, we have some sort of solution now. Thanks to those who actually helped instead of flaming us for not using Linux/Nginx/Claude/CoudFlare/whatever. I'll share the solution below but first some clarifications are in order.
OK, serious question. About 2/3 of our customers are on PHP 7.3, one is on 5.6 (all on Windows, Apache 2.4, PHP started as a Fastcgi process, not Apache module). They can't install the latest PHP. We've done the recommended PHP settings mitigations, but they are not enough.

This resolves the emergency, so now we have some time to think. First order of business is to have a serious chat with the boss and tell her to have a serious chat with the customers and explain them that they are at risk running obsolete versions.

But that upgrading them is a hell of lot of work that cannot be done for free, so they need to allocate some budget for it. Once this is done we could get to it with the help of Claude and do some extensive testing. And if they can't shell the money they shouldn't blame us.

Any suggestions what else to do? I've seen recommendations to use AppArmor to prevent the server from spawning processes - but that's a Linux thing and they are all using Windows.

I recently had to set up a WireGuard VPN. Never done that before. Win10 server, clients for Win10, Linux Mint, Android/iOS phones. Setting up the mobile clients was especially cumbersome - the app can get a config from a QR code but nothing generates it.

So, I wrote a guide and two helper PowerShell scripts; one of them generates QR codes for the mobile clients (among other things). Decided to make them (scripts and guide) public, in case it helps others: gitlab.com/-/snippets/606917…

Can anyone recognize the ransomware from this ransom note? id-ransomware is of no help.

Large files (probably larger than 1 Mb but I don't know where the cut-off is exactly) have only their first and last 9216 bytes encrypted; smaller files are encrypted completely.

Attention SIP botnet herders! Fix your bots! They are not processing your template correctly. For 3 days in a row, the only messages my SIP honeypot gets from the attackers look like this: OPTIONS sip:${RAND_ALPHA=8}@${DADDR} SIP/2.0 The "From" and "To" fields are borked too.
