    A pineapple can have any subnet it wants. Also I have multiple subnets that start 172.16.xx.xx

      Yeah, it’s not that it’s not valid for private networks, it’s that 172.16.42.x is common for WiFi Pineapples

      It’s not that it’s on the 172.16.0.0/12 range. That’s totally normal and used for all kinds of stuff.

      It’s that it’s in 172.16.42.0/24 which is the default dhcp settings for a wifi pineapple. It’s the /24 mask given on the .42 that’s a little suspicious because that’s not a common range for anything else.

      Being assigned one of those specific 253 hosts with that subnet mask would definitely make me think twice.

        Well now I know. I operate a ton of /24 subnets in the 172.16.0.0/12 scope. Technically I could fit them in the 192.168.0.0/16 scope, but I have lots of students connecting SoHo wifi-routers to the subnets, and this way it’s pretty easy to tell, if someone put the WAN cable in a LAN port when people are getting 192.168.1.0/24 DHCP offers.

          I use 172.31.254.0/23 on my WiFi router. I guess I’d confuse you. /23 to just separate it nicely into 2 /24 blocks.
          172.31.254.0/24 range is for manual assignments and 172.31.255.0/24 range is given out by DHCP.
          I do not need that many IPs, it’s just for convenience.

          I chose this range because of my school as it uses 192.168.0.0/16 range.
          To help mitigate my possible mistakes when connecting to school network, I set the DHCP lease time to just 5 minutes.

            I do similar for my home network, mostly for a combination of future proofing and ease of use.

            Realistically it would probably make more sense to segment it with more networks, but I’m only going to go so far with complexity for my home production

          It’s just one of many private ranges.

          Sure, it’s one of many, but how often do you see that specific (42) block used? I honestly don’t think I ever have, outside of a pentest lab. The 172.16.42.0/24 (not just any 172.16 like you’re saying) block is the default for a WiFi Pineapple. Any other range is usually ok, but the 42 on a /24 granting WAN access specifically would make me (and most people who actually know what a WiFi Pineapple is) avoid that network.

          Saying 172.16.0.0/12 is usually for pentesting scummy thing is very misleading…Saying it’s dangerous is like saying every websites using .xyz domain is dangerous(which makes little more sense than this, btw)

          You clearly don’t know what a WiFi Pineapple is, because we’re zeroing in on the 42 and you liken it to the entire 172.16 block. And linking every .xyz domain to a specific block (42) that is used by default for a pentest device is even more misleading.

          There’s nothing at all suspicious about the 172.16.0.0/12 address block.

          Correct. However the 172.16.42.0/24 block is the default for a WiFi Pineapple. Any other range is usually ok, but the 42 on a /24 specifically would make me (and most people who actually know what a WiFi Pineapple is) avoid that network.

      HTTPS solved much of the security issues of untrusted networks. As long as you’re not doing banking or whatever, you should be fine without a VPN.

        Why would banking be an issue? I get that its a target, but I really would expect a bank to take care of their TLS.

          Also i would expect banks to use some sort of 2FA where you have to manually confirm any transaction on your mobile device, or enter a code generated from there into your computer.

        It should be fine as long you don’t click through any SSL errors. And something like a bank should have HSTS enabled, meaning your browser will refuse to load the site if there’s an SSL error.

          They don’t let me choose a password longer than 6 characters. I don’t assume anything about my bank’s security.

    The only part of this I didn’t immediately realize is the wifi pineapples default IP range.

    From now on, I’m going to set that as my clients default public IP range to troll anyone who knows.

    So I guess I must be a leet haxor because of all the businesses I configured for the 172.x space because 192.168.x space was too small and 10.x space was way the hell too big.
