Strange network activity on mikrotik, am I the only one?

Question

Computer networks

On all (more than 10) mikrotik devices, with different architectures, I see strange network activity in the torso (even when all physical network interfaces except ISP are disabled):
185.156.73.125:40230
and a few more, but this connection is definitely on everyone.
How to check for yourself:
winbox - tools - torch, select interface (your ISP interface) - entry timeout 10+ minutes - uncheck src / dst v6, check port, source and dst addresses 0.0.0.0/0. Let's start, wait.
