I both understand the [WayBack] Urgent security advisory – MikroTik and the users reluctant to upgrade: Mikrotik has a history of updates breaking existing behaviour and underdocumenting features and release notes.
The attack is over the www or www-ssl services which by default run on port 80 and 443. You can see on which networks they are bound using this example from the terminal:

The first trick works for WinBox 3.7 on Mac [download], the second doesn’t.
First trick:

Mikrotik and SFP versus SFTP+ is always confusing especially as the text on their equipment and their documentation doesn’t show well which situations work.
Equipment text is further on, this is their text searchable documentation:
| Brand | Model | Distance | Rate | Connector/Cable type | Wavelength | Tested with | Works / Doesn’t |
|---|---|---|---|---|---|---|---|
| MikroTik | S+DA0003 | 3M | 10G | Twinax Copper | — | All MikroTik products with SFP/SFP+ interfaces | Natively supported |
As usually, a long search in the forums reveals the background information:
[WayBack] SFP in SFP+ slot – MikroTik RouterOS: 10Gb SFP+ sockets are usually backward compatible with SFP, but this is not guaranteed.
There are two tricks involved to get an SFP connection between these devices working:

Maybe for my LoT (LAN of Things): having multiple (even many) local LANs some each with their section of LoT equipment nicely separated and partially being able to talk to some of the other LANs or part of the outside world.
Some links that might help me getting this set up:

Just over a year after this got posted, I wonder what the current state of affairs is. Did it get a lot worse or just a little (as when writing this in November 2016 my guess is that it won’t get any better soon):
To repeat +Thomas Mueller ‘s words:
Internet of default passwords …
Sounds bad until you realize that it’s even worse. There are millions of devices out there that can be or have already been compromised and can get their owners into deep shit, without their owners even doing anything wrong. And keeping your virus scanner up to date won’t help at all (it doesn’t really protect your PC either, but that’s a different story).Just watch the first 10 minutes of the video, but be warned, it might ruin your day.
Via +Joe C. Hecht:
I found this to be a superior product – If you are into security, this episode was worth a listen. I hear they are into talking about home servers too. I like that.
A new TechSNAP is OUT: http://bit.ly/tsnap288

Similar to IP ranges for private networks that are safe for testing
there are also locally administered MAC address ranges safe for testing
Thanks to [WayBack] Sam and [WayBack] Peter for answering.
