To my own shame, yes, that's correct. And I say "to my own shame" because about 10-15 years ago I was a techy/computer guy and normally would have known better, it didn't even cross my mind, also, back 10+ years ago I don't recall random people using means to find and access the average Joe's ftp to cause some havoc as a common thing. I'm sure it happened but the security issues in the past were definitely not like they apparently are today.
I haven't kept up with most computer related stuff in about a decade, my desktop PCs (which I put together) components were bought back in September 2011. About a month ago when I was playing around with my PC, I ended up looking at different pc components for the heck of it, and I have to say that what's out there now, and for those prices are from perspective absurd, but in a good way. I frankly can't grasp why the average tech guy would need some several TB of storage space unless they were ripping and or downloading full bluray isos constantly lol.
Anyway, as an update to what happened, after re attaching my usb hardrive to my router and re-enableing my ftp and this time with credentials being required, within just 12 hours of enabling it, at least 2 individuals tried accessing my WAN. I only knew about it because Monday afternoon I went to my routers GUI through my DDNS and there was a lock out for too many failed attempts. When I got in and looked at the system logs, sure enough this showed up,
