  • In this video, I demonstrate how to perform firewall detection with Nmap through the use of ACK probes. Nmap is a free and open-source network scanner created by Gordon Lyon. Nmap is used to discover hosts and services on a computer network by sending packets and analyzing the responses. Nmap provides a number of features for probing computer networks, including host discovery and service and operating system detection.

    @HackerSploit I love your videos, I’m using them partially to prepare myself for the OSCP, I was wondering if you can do a video on encrypting a file with AES 256bit encryption. And essentially bypassing a payload on the best firewalls. Thanks in advance you’re my favorite CZcamsr bro

    I’ve gotten tcpwrapped which, from some research, means there’s a firewall or something present.
    However, I’ve ran: nmap -sS -A -f (fragmentation? I believe) and was able to get results

    you are sending TCP ACK flag to check if you get RST response or not. What about checking with SYN or SYN-ACK flag? Is it possible? Does it have the same effect?

    Why is it important here to use Ack instead of simple Sym ? In both cases we should get a RST if there is no Firewall, wouldnt we?

    • @pinkyakp
      @pinkyakp Před rokem +3

      remind
      sending a SYN packet to initiate a connection and waiting for a SYN-ACK response to determine if the port is open, an
      ACK packet is sent with the purpose of determining whether a firewall is present on the target system.
      The idea behind an ACK scan is that most firewalls allow incoming ACK packets, as they are used to acknowledge receipt of legitimate traffic. If an ACK packet is blocked or filtered, it could mean that a firewall is present on the target system. However, the drawback of an ACK scan is that it cannot differentiate between open and closed ports, as an ACK response can be sent by both open and closed ports.
      i Hope u got it :)

    Hi, using nmap -sA - -reason it tells me all scanned ports are unfiltered because of resets.
    By using nmap - -badsum it tells me all scanned ports are filtered.
    Any idea why it happens? My IP target is a iPad on LAN, could it be a firewall filtering some ports rst?

      It's most likely a firewall in the middle that block that ping scan. Tell nmap to not performing ping scan by adding a -Pn tag

      @bhsamuraii Před 4 lety +2

      Well, if the device your scanning is genuinely down, then it cant be nmap's fault.
      However, if you are scanning a mobile phone or tablet, you might want to turn it on or use it. What I have found is that even if your device is powered on but not in use, nmap for some reason cant detect it...
      Hope this helps!

      You can use virtualbox to install any other OS(kali) inside windows.... And you cannot hack WiFi using termux without your wireless card being put into monitor mode. It's a long and complex process to do in an android....
