You are pulling at the wrong horse. Routers are the interface between the outside and inside.

If someone activate the ransomware then it is already inside and out of reach of RouterOs.

Patch your systems and instruct you employees to never ever open attachments that are suspicious or unexpected.

if you didn’t explicit redirected the port from outside ton ONE IP inside, you won’t have SMB traffic in the router form outside to inside.

If you virus/problem is inside, the routers is NOTHING there…
