Introduction to Packet Analysis - Part 7: Capturing Network Traffic with TCPDump (Part 1)
 
07:45
Author: Jeremy Druin Twitter: @webpwnized Thank you for watching. Please help by up voting, subscribing or even support this channel at https://www.youtube.com/user/webpwnized Description: From the ISSA-KY Network Packet Analysis Workshop, this video series introduces the basics of the OSI packet model, application packet model and common network protocols. Later videos will discuss specific protocols such as TCP, IP, UDP and HTTP. Later, packets will be captured into PCAPs which are analyzed with Wireshark and Network Miner. We continue the series on network packet analysis with capturing network packets into PCAP files with TCPDump. TCPDump is available on most versions of Linux and is preinstalled on Kali Linux. It is easy to use even for beginners and captures files in the PCAP format. The PCAP format is the standard network packet capture file format allowing the files to be opened in other tools such as Wireshark and Network Miner. A TCPDump port for Windows is also available for operating systems like Windows 10. Tools discussed in other videos are Wireshark, Network Miner, Scapy, TCPDump and Traceroute for Linux. Later videos will cover usage of some of these tools. Also, other videos on this channel discuss tools like scapy. For videos that go into depth on these tools please see videos at playlist https://www.youtube.com/playlist?list=PLZOToVAK85MqkNyx8VKPT7h9ZlxkX2krG. If you would like access to the full course including the lab exercises and walk-through, please consider taking the course at http://ellipsisinfosec.teachable.com/p/introduction-to-network-packet-analysis-and-forensics The webpwnized YouTube channel is dedicated to information security, security testing and ethical hacking. There is an emphasis on web application security but many other topics are covers. Some of these include forensics, network security, security testing tools and security testing processes. The channel provides videos to encourage software developers and system administrators to perform security testing. Also, the channel educates the next generation of security testers and bug bounty hunters who want to respectfully, legally and ethically help system owners that allow security testing.

Network Traffic & Interfaces
 
03:32
Network Traffic & Interfaces Encapsulation helps prepare Host Networks, starting with the local segment, and when necessary, beyond network boundaries. At Layer-4, the Payload receives Network Protocol & Port information. At Layer-3, IPv4 and IPv6 Addresses define the Sender & Receiver Internet address. An IPv4 address is a logical, 32-bit address used in local and internetwork communication. Inside the Layer-3 Packet, a Source & Destination IP Address exist to move traffic across Networks. At Layer-2, MAC Addresses define a Network Device’s address for Link-Local communication. The MAC is a unique 48-bit hexadecimal-based hardware address. Inside the Layer-2 Frame, a Source & Destination MAC Address exist to help move traffic on the Local Network. In order for networks to behavior, it’s important that Host Network Interfaces are configured with unique Layer-2 & Layer-3 Network Addresses. Network interfaces identify the physical and logical ports on which a Host can receive or send Network traffic. In addition to physical Network interface, like a Wired or Wireless Card, or group of Switch Ports, several types of logical interfaces exist, including: Loopback, generally for testing & network administration Bridge, like when joining a wired & wireless interface on the same local segment under a common network address Virtual, which enables an interface to participate in a Virtual LAN, Tunnel, for point-to-point links across WANs, And more. Network traffic can generally be described to move in either of two directions, relative to an interface: egress or ingress. Egress describes traffic leaving an interface—think egress, or exit. Ingress describes traffic approaching an interface—think ingress, or, in. Colloquially, Network Traffic is also said to move “Downstream” or “Upstream” relative to a Network’s Topology, Devices, and/or Users. In networking today, Hosts use both Layer-2 and Layer-3 Addresses to communicate via one of three methods. Unicast traffic involves one-to-one communication, where either the intended recipient’s Layer-2 or Layer-3 Network Address is known. For example, an ICMP Ping Reply is Unicast traffic. Broadcast traffic is one-to-all communication, where all Hosts on the Layer-2 or Layer-3 Network are the intended recipients. For example, a Host needing a DHCP Address would use the Layer-2 Broadcast address FF:FF:FF:FF:FF:FF in attempt to Discovery a DHCP Server on the Local Network. All Hosts on the Local Network would receive the Broadcast message. Multicast traffic is one-to-some communication, where not all, but some Network Devices are the intended recipients. For example, Dynamic Routing protocols use Multicast addresses to communicate solely among Routers, but not with other Network Hosts.

[A] Actually they have shown that it detects many threats that all other anti-virus software misses mainly because it has access to data those other anti-virus programs do not like the networking history of the application. [Q] Can this monitor my whole houses network? [A] Only if it's running on a router running Windows, otherwise it's designed to only monitor the PC's it is installed on. That being said it has capabilities that centralized solutions like pfsense do not like integration with applications and services running on your PC to detect exactly where traffic is coming from and going to. [Q] What are the remote connections? [A] This allows you to connect remotely to your computer and monitor GlassWire like you were there sitting at the PC. This is honestly one of my favorite features of the software since I can monitor all the PC's in my house with the Elite license and always know what is going on everywhere. [Q] The text is to small I can't read it?!?! [A] Watch in 1080p or higher full screen, since I'm capturing the screen this video isn't really meant for people to watch in a little window. [Q] The DNS cache was why bing and google still worked when blocked in the host file. [A] You are correct, I should have run "ipconfig /flushdns" to clear the cache and it would have worked. Strange thing is chrome doesn't use the DNS cache since it always works the second I change the hosts file. ▼ Support me by sending BitCoin (Wallet Address) ▼ 18Su2PV63BabMZWwYEhgXC8obK1XBVveCp ▼ Get 10% off Kinesis Split Ergonomic Keyboards & Pedals ▼ http://www.kinesis-ergo.com/ [use code 'Barnacules' at checkout to get 10% off] ▼ Join my [email protected] team and help cure diseases with spare CPU/GPU cycles ▼ Barnacules Nerdgasm Team # 231300 Download Client @ http://folding.stanford.edu/ ** Top 10 contributers shown on Twitter weekly! ▼ I am now live streaming on Twitch so come give me a follow to receive notifications when I'm streaming ▼ https://www.twitch.tv/barnacules 💥 See my Amazon Store for all the products I use & review 💥 https://www.amazon.com/shop/barnacules1

Sniff the traffic of any device on your network
 
06:25
In this video, I show how to use arpspoof and mitmproxy to sniff the HTTP and HTTPS traffic of any device on your network. I use arpspoof to trick the device into thinking my laptop is the router and then use mitmproxy to view the incoming and outgoing requests. I compelte a game of candy crush to show the data that the ipad is sending to the remote server and the response it receives. Follow the instructions below to try this yourself. Install mitmproxy and arpspoof (Debian based OS): -------------------------------------------------- apt-get install mitmproxy apt-get install arpspoof Install mitmproxy and arpspoof (Mac OS X): ------------------------------------------- Install Macports and then run: port install dsniff pip install mitmproxy Certificate ----------- During the installation of mitmproxy, a certificate file will be created called mitmproxy-ca-cert.pem . Copy this certificate to your device and install it. In my case, I emailed it to my iPad, clicked the attachment and followed the onscreen instructions. This step will vary depending on the device. ip forwarding, redirect traffic to mitmproxy, start mitmproxy in transparent mode: ----------------------------------------------------------------------------------- sysctl -w net.ipv4.ip_forward=1 iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080 iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 443 -j REDIRECT --to-port 8080 mitmproxy -T --host Use arpspoof to trick target device into thinking we are the router: (where 10.0.1.7 is the target device and 10.0.1.1 is the genuine router) -------------------------------------------------------------------------- arpspoof -i eth0 -t 10.0.1.7 10.0.1.1 That's it. You should now be able to view the target devices traffic in your mitmproxy window.

Packet Loss vs Latency
 
07:36
https://www.thetechfirm.com I get involved with a lot of performance related troubleshooting and the majority of the time the root cause is related to packet loss or excessive latency. Let me start with explaining the difference between the two terms. Packet Loss is literally when you do not receive a packet. This can be caused by a variety of reasons such as corrupted frames, RF interference, half full duplex mismatches, dirty fibre connectors, oversubscribed links and routing issues. Packet loss is an issue since TCP based protocols will have to wait and retransmit lost frames. The key word here is ‘wait’ since waiting implies you are no longer transmitting. For example, if you had a 500ms delay on 10 Mb link, you lost the opportunity to transmit 5 Mb within that 500 ms time frame. If your application is UDP based, all bets are off and it is up the application to decide what to do. I’ve seen UDP based applications react to packet loss by terminating the connection, resend data or corrupt data. With VOIP you hear echo and distorted audio. read the rest at https://www.networkcomputing.com/networking/packet-loss-vs-latency-analyzing-impact/523143466

iftop - linux traffic monitoring
 
02:37
iftop is a command-line system monitor tool that produces a frequently-updated list of network connections. By default, the connections are ordered by bandwidth usage, with only the "top" bandwidth consumers shown. The iftop website gives the following description: "iftop does for network usage what top(1) does for CPU usage. It listens to network traffic on a named interface and displays a table of current bandwidth usage by pairs of hosts. Handy for answering the question 'why is our ADSL link so slow?'".

Network Traffic Analysis using Deep Packet Inspection and Data Visualization (SHA2017)
 
25:12
Eventpad: the Sublime editor for network traffic For the protection of (critical) infrastructures against complex virus attacks, deep packet inspection is unavoidable. In our project SpySpot we are developing new tools and techniques to assist analysts in gaining insight and reverse engineering WireShark PCAP files. In this talk we present and demo a new data visualization system Eventpad to study PCAP traffic by visualizing patterns according to user-defined rules. We illustrate the effectiveness of the system on real-world traffic including VoIP communication and Ransomware activity in file systems. #NetworkSecurity #DeviceSecurity ArrayX

How To: Use SSLstrip On Kali Linux
 
11:22
In this tutorial, I'm going to teach you how to use sslstrip on Kali Linux. Additionally, we will simulate a target to demonstrate how sslstrip is used to capture a target's Facebook login information. WHAT WILL YOU LEARN IN THIS TUTORIAL? 1) Nmap You will learn how to use Nmap to scan a network and discover hosts. Nmap is the tool that we'll use to find our target. 2) ARPspoof You will learn how to use ARPspoof to redirect a device's internet traffic to your computer. ARPspoof is the tool that we'll use to intercept the target's HTTPS requests and login information. 3) IPtables You will learn how to enable IP forwarding and create an iptables rule to forward and filter internet traffic. These are the tools that we'll use to redirect our target's port 8080 traffic (HTTPS traffic) to port 80 (HTTP). 4) SSLstrip You will learn how to use sslstrip to observe and manipulate internet traffic. SSLstrip is the tool that we'll use to convert our target's HTTPS requests into HTTP requests. It will also be used to capture our target's HTTP POST data (i.e. usernames and passwords). NOTE: It is illegal to perform this attack unless you have explicit permission from the target. The information presented in this video is for educational purposes only and should not be used outside of a secure test platform.
