spoofing

I'm working on a web service that would use an SMS gateway to receive instructions from customers. Since this would be a commercial product I would like to implement a safeguard to protect our system from SMS spoofs. I don't want people impersonating others by spoofing their number. I've noticed that Twitter allows people to tweet through text messages, how can they make sure that messages are actually genuine? Is this possible, and if so how do I accomplish this? Or should I ignore this and just deal with it through support should they get through. How do users spoof their numbers? Every

I am now load testing a website through jmeter from my machine. But I want a real world scenario , so can ip aliasing or ip spoofing be used by jmeter which will look like requests are being sent from different ip addresses.? Yes it can, see property Source IP address: : http://jmeter.apache.org/usermanual/component_reference.html#HTTP_Request Note that you must use HTTPClient implementations.

How can I spoof the user agent of a JavaScript GET request? setRequestHeader with User-Agent isn't allowed: xmlHttpRequest.setRequestHeader("User-Agent", "..."); tskuzzy You can't do this in a half-decent browser because of security issues surrounding it. You don't want XSS scripts to be changing request headers and running rampant on your site. However I believe there's a workaround in IE if you use VBScript : MyHttp.setRequestHeader "User-Agent", "MyCustomUser" The alternative is to have a web page on your site dedicated to forwarding a GET request, changing the appropriate headers as

I have been using wire-shark to analyse the packets of socket programs, Now i want to see the traffic of other hosts traffic, as i found that i need to use monitor mode that is only supported in Linux platform, so i tried but i couldn't capture any packets that is transferred in my network, listing as 0 packets captured. Scenario: I'm having a network consisting of 50+ hosts (all are powered by windows Except mine), my IP address is 192.168.1.10, when i initiate a communication between any 192.168.1.xx it showing the captured traffic. But my requirement is to monitor the traffic of 192.168.1

I am using Apache HttpClient for generating Post request and submitting the data. Since remote application relays on IP address of the user that's submitting the data, I want to send post request for user specified IP address. How do I configure this? public static void loginUser(String username, String password, String ip) throws Exception{ try { HttpClient client = new DefaultHttpClient(); HttpPost httppost = new HttpPost("http://login.myapp.com/"); // Request parameters and other properties. List<NameValuePair> params = new ArrayList<NameValuePair>(2); params.add(new BasicNameValuePair(

I have two machines each with two valid network interfaces, an Ethernet interface eth0 and a tun/tap interface gr0 . The goal is to start a TCP connection on machine A using interface gr0 but then have the responses (ACKs, etc) from machine B come back over the Ethernet interface, eth0 . So, machine A sends out a SYN on gr0 and machine B receives the SYN on its own gr0 but then sends its SYN/ACK back through eth0 . The tun/tap device is a GNU Radio wireless link and we just want the responses to come through the Ethernet. What's the easiest way to accomplish this? I need to research more on

I don't want to modify the ethernet portions of the frame, but I need to modify the IP packet and the data portion of the frame. I try sending a raw frame and it still puts in the IP information. I basically need to send a frame without defining the endpoint except in the bits I'm sending. Here's what I got: Socket s = new Socket(AddressFamily.Unspecified, SocketType.Raw, ProtocolType.Raw); EndPoint ep = new IPEndPoint(IPAddress.Parse("205.188.100.58"),80); s.SendTo(GetBytes(""),ep); //im sending nothing, so i expect the frame to just have ethernet stuff s.SetSocketOption(SocketOptionLevel.IP,
