Altering packets on the fly with scapy as a MITM

≡放荡痞女 提交于 2019-12-06 01:11:19
Assuming I managed to be in the middle of the communication between a client and a server (let's say that I open up a hotspot and cause the client to connect to the server only through my machine). How can I alter packets that my client sends and receives without interrupting my own communication with other services? There must be a way to route all of the packets the client both sends and is about to receive (before forwarding them to him) through my script. I think that the correct direction of going about accomplishing this is with iptables but not sure exactly what arguments would fit to

Breaking TLS security by fully recording the handshake

假如想象 提交于 2019-12-02 07:57:52
问题 I have been looking at TLS recently, and I am unsure as to why it is so secure, but probably thanks to a misunderstanding of how it works. But if the entire handshake is recorded, either using a man in the middle attack or a packet sniffer on the target computer, then any of the remaining communication can be decrypted as you would have all the info that the client and the server used to generate the encryption keys. I doubt there would be such a hole in tls, but could anyone tell me how tls

Embedding Image/Video Stream into webpage

I'm trying to create a PHP webpage that allow the visitor to see a video stream or an image coming from a webcam without allowing the visitors to grab it's original URL/URI . In other words, I have an ip camera operating at a given address:port and I can see the stream embedding in a HTML body something like this: <img src="http://5.246.77.89:8080/videostream.cgi?user=myusername&pwd=mypass&resolution=32&rate=15" alt=""> or alternatively if we want a static image: <img src="http://5.246.77.89:8080/snapshot.cgi?user=myusername&pwd=mypass&amp" alt=""> Now the problem is that if anyone look at the

We are looking for simple light weight, preferably ruby based proxy that enables us to do the following.

How does this Man-In-The-Middle attack work?

荒凉一梦 提交于 2019-11-30 06:28:32
The Django documentation on its CSRF protection states that: In addition, for HTTPS requests, strict referer checking is done by CsrfViewMiddleware. This is necessary to address a Man-In-The-Middle attack that is possible under HTTPS when using a session independent nonce, due to the fact that HTTP 'Set-Cookie' headers are (unfortunately) accepted by clients that are talking to a site under HTTPS. (Referer checking is not done for HTTP requests because the presence of the Referer header is not reliable enough under HTTP.) I have trouble visualizing how this attack works. Could somebody explain

ssh remote host identification has changed

Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that a host key has just been changed.

Capturing HTTPS traffic in the clear?

▼魔方 西西 提交于 2019-11-26 22:53:20
问题 I've got a local application (which I didn't write, and can't change) that talks to a remote web service. It uses HTTPS, and I'd like to see what's in the traffic. Is there any way I can do this? I'd prefer a Windows system, but I'm happy to set up a proxy on Linux if this makes things easier. What I'm considering: Redirecting the web site by hacking my hosts file (or setting up alternate DNS). Installing an HTTPS server on that site, with a self-signed (but trusted) certificate. Apparently,
