Hello, when conducting Nmap scan on Iphone hotspot. Scan is showing port 21 open, also port 53 and 49152. However when I run netstat scan, nothing is showing as listening on this port. On advanced port scanner it shows ftp service. and Also when trying to contect to Ftp server on command it appears to open, I receive a blank screen.
Can you please provide more information about your environment.
How many pc's are connected to this hotspot? Are they all getting a unique IP address?
Which machine are you running Nmap on? Which machine are you running netstat on?
How many devices does Nmap find? Is it detecting each OS correctly?
Which machine is detected as having FTP open? Did you install IIS/FTP on that machine?
Are you running the ZenMap GUI to run the scan? Maybe share some screen images so that we can see what you are doing.
I have only my iphone hotspot connected on the one private laptop. When i run nmap -sS scan with iphone hotspot ip address. It shows above portals as open. Im running to nmap scan on my laptop with the iphone hotspot connected. I did install IIS after seeing it open. I dont have any ftp server apart from IIS. I have Zenmap Gui installed
C:\Users\XXX>nmap -sS {ip address of iphone hotspot}
Starting Nmap 7.95 ( https://nmap.org )

Those are ports that are open on your iPhone.
On my pc, ipconfig.exe shows my IPv4 address and the address of the router.
Wireless LAN adapter Wi-Fi:
Connection-specific DNS Suffix . : mynetworksettings.com
IPv4 Address. . . . . . . . . . . : 192.168.1.4
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1
A scan of my router shows open ports and detects that it is Linux based. I see that port 80/443 is open for its web interface.
Netstat displays information about my laptop because that's where it is running. It doesn't scan a network address.
The -o switch shows the owning process id which can then be queried with Powershell's get-process cmdlet.

FTP must be open on your iPhone. From a command prompt see if you can log in anonymously.
