![]() ![]() Last year I even wrote a tool that does most of this for you and injects javascript miners into public networks. Anyone with a live boot of kali or parrot os can have this attack up and running in about 5 minutes. My favorite is testing my phone apps for random things they're sending over the internet. I use this attack pattern all the time to test devices on my home network for weaknesses. You'll see the name of the service in brackets. ![]() Netstat -a -b and look for ports marked as listening. How to identify what services are running on your listening ports The command and results are almost the same on Linux Also anything marked with private addresses such as 10.0.0.0 to 10.255.255.255 The one's marked with 127.0.0.1 you can ignore because those are only visible internally to your machine.Īnything marked as 0.0.0.0:Port will be visible to attackers on the network. The output will show you all the ports that are open and listening internally and externally. How do you see what ports are open and listening on Windows? To do what I've described above has a very low barrier of entry. If you want to dig in a little deeper into what can be done, how and with what tools, please look at these links below. If you're connecting to public wifi points you have some accepted risk. Also make sure your machine is fully patched and running all available firewall services. Any openings are potential access points. Honestly, you probably shouldn't have any ports open. Make sure that you don't have any unnecessary services running on your machine that are open to the network. Nmap even has some nifty passive scanning features where it won't even expose the attacker on the network because it just listens to who's transmitting instead of actively probing.Īlways use TLS and if you can, connect to a VPN whenever you're on a public wifi. Using tools such as nmap to first scan the network for potential targets and then port scanning each target, an attacker can quickly find you and identify any possible holes in your machine. It has an ability to filter intercepted packets by source ip,source port, destination ip. Just being on the same network as the attacker gives them the ability to scan your machine for open ports, vulnerable services running, start probing your machine. Enabling IP forwarding allows packets to pass through your machine. I recommend downloading Backtrack as it comes with all these tools out of the box. The attacker doesn't even need to arp spoof you to attack your machine though. For this guide, you will need a computer with arpspoof and SSLstrip installed, as well as nmap for finding your target’s IP address. Once the arp spoof and ipv#_forwarding is configured it's trivial to sniff your traffic, inject malicious javascript into http traffic, etc etc etc. Then all your traffic will pass through them. ![]() It's very easy to arp spoof the entire network and pretend to be the router. You're still at risk.Īn attacker doesn't need to compromise a router to attack you on a public network. Many public places have WiFi with WPA2 enabled and they just freely give out the password. Regardless if you're connected to an open access point, an access point with WEP enabled (hopefully not) or an access point with WPA/WPA2 you can be attacked. What can an attacker do if they're on the same network as you? I'm using the latest version from Kali Linux (2019_3) and MacOS (Catalina).Can you tell if the network you're attached to, assuming you're just an average user, has a been compromised? In any case, nothing appears when I trying to use "urlsnarf -i wlan0" on a new terminal, nothing appears apart from: "urlsnarf: listening on wlan0 ". But when trying to navigate the web from my phone, some pages load (Facebook, Google), but most don't (BBC or Amazon for instance). I then use these addresses to construct a phony ARP response to the victim that tells them that I am their default gateway (or any other IP address if you don't want it to be the default gateway). The commands seem to run properly (I'm having an output that look similar to the ones on any tutorial on arpspoofing on both terminals). The arpspoof.c file sends 2 ARP requests, one to the default gateway and one to the victim, to get their MAC addresses. Then, I'm launching the two arpspoof commands from two terminal windows: "arpspoof -i wlan0 -t 192.168.1.1 192.168.1.24" and "arpspoof -i wlan0 -t 192.168.1.24 192.168.1.1", knowing that these are respectively my router's and my phone's local IPs. I've set packet forwarding using echo 1 > /proc/sys/net/ipv4/ip_forward. I've set the USB ports to be accessible from the VM, and then used the adapter to connect to my wifi from the kali VM. I just received a wireless adapter ( Atheros AR9271 2.4 Ghz USB WiFi Wireless Adapter) and want to try man-in-the-middle type attacks at home, using kali Linux in VirtualBox on my Mac. ![]()
