You can do: brute force passwords in auth forms; directory disclosure ( use PATH list to brute, and find HTTP status code) test list on input to find. The port numbers are divided into three ranges: the Well Known Ports, the Registered Ports, and the Dynamic and/or Private Ports. The Well Known Ports are those from 0 through 1023. The Registered Ports are those from 1024. The entire exchange might looke like the diagram below. Alice has an IP packet of some sort (let's say an ICMP ping) to send to Bob. In order to find Bob's MAC address, Alice ARPs it. Bob responds to Alice, telling her his MAC. Microsoft Network Monitor (netmon.exe). Network Monitor 3.4 is a protocol analyzer. It allows you to capture network traffic, view and analyze it. Version 3.4 is an update and replaces Network Monitor 3.3. To measure memory consumption, use the following counters: Process\Private Bytes. Threshold: The threshold depends on your application and on settings in the Machine config file. The default for ASP.NET is 60 percent. Information about this FAQVersion 0. April 1. 5, 2. 00. Copyright 1. 99. 8- 2. Robert Graham (sniffing- faq@robertgraham.

Who is Robert Graham? Among other things, between 1. I worked at Network General Corporation on the Sniffer(r) Network Analyzer. I either wrote/rewrote/ported over 3. Sniffer. Now I'm working on an intrusion detection system that similarly does protocol analysis. Also, I helped develop the . In the early 1. 99. I help develope the RMON standard(s) and the first RMON systems. The basics. 1. 1 What is a . Like a telephone wiretap allows the FBI to listen in on other people's conversations, a . Therefore, network wiretap programs also come with a feature known as . This means that you don't need to break into a wiring closet to install your wiretap, you can do it from almost any network connection to eavesdrop on your neighbors. I'm not sure what this means in trademark law, where brandnames like . What is it used for? Sniffing programs have been around for a long time in two forms. Commercial packet sniffers are used to help maintain networks. Underground packet sniffers are used to break into computers. Used hackers/crackers in order to break into systems. Is there a single point on the Internet I can plug into in order to see all the traffic? No. The connectivity of the Internet looks much like a fisherman's net. Traffic flows through a mesh, and no single point will see it all. The Internet was built to withstand a nuclear attack - - and to survive any . This likewise prevents any single point of sniffing. They take a direct route of communication, and the traffic never goes across the outside public portion of the Internet. Any communication anywhere in the net follows a similar . How does sniffing/wiretap work? How does it eavesdrop on network traffic? Ethernet was built around a . It does this by ignoring all frames whose MAC address doesn't match. Thus, Mark can see all the traffic between Alice and Bob, as long as they are on the same Ethernet wire. What are the components of a packet sniffer? The hardware. Most products work from standard network adapters, though some require special hardware. If you use special hardware, you can analyze hardware faults like CRC errors, voltage problems, cable programs, . It captures the network traffic from the wire, filters it for the particular traffic you want, then stores the data in a buffer. There are a couple captures modes: capture until the buffer fills up, or use the buffer as a . Some products (like the Black. ICE Sentry IDS from Network ICE can maintain a full round- robin capture buffer on disk at full 1. This allows have hundreds of gigabytes of buffer rather than the meager 1- gigabyte you're likely to have in a memory- based buffer. This is able to find network performance issues and faults while capturing. Many vendors have started to add minimal capabilities along this line to their products. Network intrusion detection systems do this, but they sift the traffic for signs of hacker activity rather than fault/performance issues. What is an Ethernet MAC address? Since many machines may share a single Ethernet wire, each must have an individual identifier. This doesn't happen with dial- up modems, because it is assumed that any data you send to the modem is destinated for the other side of the phone line. But when you send data out onto an Ethernet wire, you have to be clear which machine you intend to send the data to. Sure, in many cases today there are only two machines talking to each other, but you have to remember that Ethernet was designed for thousands of machines to share the same wire. Section 1. 5. 4 explains how to discover the Ethernet MAC address of your own machine. Ethernet was designed to carry other traffic than just TCP/IP, and TCP/IP was designed to run over other wires (such as dial- up lines, which use no Ethernet). For example, many home users install . You just can't send data raw over the wire, you must first do something to it that Ethernet understands. In much the same way, you can't stick a letter in a mailbox, you must first wrap it in an envelope with an address and stamp. Therefore, Alice must first hand off the packet to the first router. Each router along the way will examine the destination IP address (1. All Alice knows about is the local connection to the first router, and Bob's eventual IP address. Alice knows nothing about the structure of the Internet and the route that packet will take. She uses the Ethernet to do so. An Ethernet frame looks like the following. The TCP/IP stack then sends it to the Ethernet module, which puts 1. MAC address, source MAC address, and the ethertype 0x. TCP/IP stack should process the frame. It also attaches 4- bytes on the end with a checksum/CRC (a validator to see if the frame gets corrupted as it goes across the wire). Proper adapters, however, have a hardware chip that compares the frame's . If they don't match, then it discards the frame. This is done at the hardware level, so the machine the adapter is attached to is completely unaware of this process. It looks at the 0x. TCP/IP stack for processing (which will presumably forward it to the next router in the chain toward the destination). The wiretap, however, breaks the rules and copies the frame off the network, too. The Ethernet address is considered part of the MAC sublayer. What is the format of the MAC address? The Ethernet MAC address is a 4. This number is broken down into two halves, the first 2. Ethernet board, the second 2. This guarantees that no two Ethernet cards have the same MAC address (unless the vendor fouls up). Duplicate address would cause problems, so uniquess is very important. This 2. 4- bit number is called the OUI (. One bit indicates if the address is a . The first byte contains the binary representation of 0. This is a special multicast packet that is sent to all machines that run the . What is my Ethernet address? Win. 9x. Run the program . It will show the MAC address for your adapters. Sample results are. Windows NT IP Configuration. Host Name . Sample results are. Link encap: Ethernet HWaddr 0. A: 3. 6: 3. E. inet addr: 1. Bcast: 1. 92. 0. 2. Mask: 2. 55. 2. 55. UP BROADCAST RUNNING MULTICAST MTU: 1. Metric: 1. RX packets: 1. TX packets: 9. 94. Interrupt: 5 Base address: 0x. Use the . 1. 5. 5 What are the Ethernet addresses of machines I'm talking to? For Win. NT and UNIX, use the command . Can I sniff a connection between two people without having access to their wire? In other words, you are asking about this scenario. Alice and Bob are in New York and Texas and are talking. The answer is of course . You have to have access to the wire that the communication is going across in order to eavesdrop. Same as with telephones, same as everywhere. Typical examples are. Break into Alice or Bob's computer and install sniffing software that you remotely control. Close to the wire. In some situations, like cable- modems, DSL, Ethernet VLANs, etc., you can redirect traffic between two people to go through your own machine. This is because while you are not directly in the path of communication, you can sometimes move that path to flow past your own computer. It's much like the concept that you can divert a stream slightly, though not very far. How can I defend myself against packet sniffers? How can I stop people from sniffing my data? While you can configure your local network to make sniffing hard, you are pretty much powerless stopping people from out on the Internet from sniffing your traffic. The best defense in this case is to encrypt your data, so that while they can sniff it, they cannot read it. Some techniques are. SSL. It allows encrypted web surfing, and is almost always used in e- commerce when users enter their credit card information. It passes through corporate firewalls, which may monitor the traffic. It often gets logged and saved for extended periods of time. It may get accidentally misdirected, and end up in somebody else's mailbox. The best way to keep such e- mail secret is to encrypt it. The two common ways of doing this are with PGP (Pretty Good Privacy) and S/MIME (Secure MIME). PGP can be purchased as an add- on to many products. S/MIME is built into e- mail programs by Netscape and Microsoft. You should immediately replace telnet with this service. Numerous other protocols can be tunneled through ssh connections (i. The product was originally developed by a Finish company http: //www. VPNs (Virtual Private Networks)VPNs provide encrypted traffic across the Internet. However, if a hacker compromises the end- nodes of a VPN connection, they can still sniff the traffic. A typical scenario is an end- user who surfs the Internet normally and gets compromised with a Remote Access Trojan (RAT) that contains a sniffing plug- in. When the user establishes the VPN connection, the sniffing program is able to see not only the encrypted traffic that can be seen on the Internet, but also the unencrypted traffic before it gets sent through the stack to the VPN. How can I stop people from sniffing my passwords? The data- encryption solutions above also provide for secure authentication. There are other solutions that provide for secure authentication as well. SMB/CIFSIn the Windows/SAMBA environment, make sure that you have the older Lan. Manager authentication turned off. This requires SAMBA v. Win. NT SP3 or later, and so on. Kerberos v. 5Both Windows 2. UNIX provide support for Kerberos authentication.
