## Script to intercept Modbus TCP payload

I am trying to create a Scapy script to modify payload of Modbus TCP packets (function code 3 & 2), but could not succeed. Script is not intercepting traffic and modifying payload.

Is there anyone out there who is successful in intercepting Modbus TCP packets? Is there a sample script available with anyone? I am trying to modify ModbusPDU03ReadHoldingRegistersResponse and ModbusPDU02ReadDiscreteInputsResponse in payload.

## How to intercept data my TV communicator sends and receives?

I wish to check how and what is being sent when I interact with my TV via the remote that talks to the communicator box (not smart tv). I am curious what protocols are used, and how often does the communicator phones home. Does it send encrypted data or not. The ISP is also my TV network provider.

To tackle this question I tried to use a recently obtained knowledge of ARP poisoning. I installed a Kali Linux and used arpspoof. I also enabled IP forwarding and launched Wireshark but failed to receive any kind of packets that I could attribute to my communicator box. The TV also continued to operate normally which leads me to 2 theories:

1. My ARP poisoning failed, that is why TV worked normally and Wireshark failed to show any packets.
2. ARP poisoning worked, TV continued to work so IP forwarding must have worked too, but why would Wireshark then not capture anything?

Prior to that, I tested ARP poisoning on a 2nd home PC and successful intercepted traffic.

What are my options? Any alternatives to ARP spoofing if I wish to observe traffic my home appliances are sending to the internet? A special kind of router to put between TV communicator and the rest of the home network?

## Localhost intercept not working for burp suite

I configured my Firefox proxy to send my php website traffic running on localhost to burp suite for intercept but its not intercepting anything.My firefox and burpsuite configurations here.I’ve tried using different port other than 8080,went to about:config and enable localhost hijacking but still it wont work.Days ago it was working fine but now its not.

## Magento 2 Intercept Route

I got a small question. I have custom products/categories in my shop. Now depending on the user, it may or may not visit the specific category or product. Is there an event or other way to ‘hook’ into, or ‘intercept’ a route and execute some logic?

For example: i have customer x and customer y, product x and category x customer y does not have access to category x, i want to redirect the customer to the homepage when the customer visits category-x.

## Is it possible to intercept messages from email address or phone number that is expired? if yes, how?

I used to have an email account for receiving important messages but it was deleted by the email provider in which they claimed that deletion of the email address is still in progess but cannot be reversed. I desperately need that email address to receive important messages bascially i wonder if its still possible to intercept messages that were sent to the email address If yes, how? Also does this work on phone number as well? is it possible to intercept SMS that is sent to phone numbers in which {the phone number) is no longer in service?

In other words—if someone send a message to that email address/phone number, is it possible to intercept that message before it reached the email address/phone number? If yes, how?

## Intercept Onepage\SaveOrder

I’m trying to add a certain process in the Magento\Checkout\Controller\Onepage\SaveOrder so I decided to implement a plugin for that. But after creating the di.xml and the classes needed when I try to purchase an item and fillout all the shipping details and selected the needed payment method. Upon submission of the order I was expecting for the function to be run. But somehow it’s not being called. Can any help me with this or if anyone has any idea what I did wrong. Below are my codes

content of di.xml

<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/ObjectManager/etc/config.xsd">    <type name="Magento\Checkout\Controller\Onepage\SaveOrder">         <plugin name="Custom_Module_Plugin" type="Custom\Module\Plugin\SaveOrderPlugin" sortOrder="10" />     </type> </config> 

content of SaveOrderPlugin.php

<?php  namespace Custom\Module\Plugin;  class SaveOrderPlugin {        public function aroundExecute(\Magento\Checkout\Controller\Onepage\SaveOrder $subject, \Closure$  proceed)     {         // logging to test override             $logger = \Magento\Framework\App\ObjectManager::getInstance()->get('\Psr\Log\LoggerInterface');$  logger->debug("********** " . __METHOD__ . ' - ' . __LINE__);          // call the core observed function         $returnValue =$  proceed();           // logging to test override                 $logger->debug("********** " . __METHOD__ . ' - ' . __LINE__); return$  returnValue;     } } ?> 

As you can see I was expecting an output in the console log as shown below but this does not show. Also I tried intercepting other classes like Magento\Quote\Model\QuoteManagement and it worked as expected. But the reason I want to override the Magento\Checkout\Controller\Onepage\SaveOrder is primarily because I want to retrieve a certain parameter when the order of item is submitted.

Anyone have an idea what I did wrong here?

## Unable to intercept android app traffic neither in Burp Suite nor in Network Profiler. Can anyone help?

I need to perform MITM attack on an app which doesn’t use HttpURLConnection and OkHttp libraries for network connection.

Analysis : 1. Configured burp on the devices, able to capture request of chrome browser but not the test app. 2. Wireshark is showing, communication of test app is happening on TLS 1.2 only. 3. Tried Network profiler of android studio but nothing shown.

What we should do if network connection is done with ‘CURL’ which I am not very familier with?

## Can I intercept and impersonate a server over an HTTP wireless connection?

Let’s assume I have a strong enough antenna at exactly the same frequency as the victim. If it sends a request over unprotected http to the router, could I then listen to that request and respond to it before the router does? Would I need the MAC address of the victim too?

## Intercept network traffic with a hub

If I plugged a hub inbetween a switch and firewall, that also had a device running wireshark or similar capture software connected, due to the way a hub operates, would I be able to read ALL of the traffic between the switch and firewall, E.g. All inbound and outbound packets?

## Hyperbolic Intercept (Thales) Theorem

Is there an Intercept theorem (from Thales, but don’t mistake it with the Thales theorem in a circle) in hyperbolic geometry?

Euclidean Intercept Theorem: Let S,A,B,C,D be 5 points, such that SA, SC, AC are respectively parallel to SB, SD, BD; and SB > SA, SD > SC. Then, we have SB/SA = SD/SC = BD/AD

(see wiki illustration)

Hyperbolic Intercept Theorem? The concept of parallel lines is tricky here… Let’s place ourselves in the Klein model, consider a triangle $$0xy$$, two positive real numbers $$p,q$$, and construct the Einstein midpoints $$x’=m(x,0;p,q)$$ and $$y’=m(y,0;p,q)$$, defined by $$m(a,b;p,q)=\dfrac{p\gamma_a a+q\gamma_b b}{p\gamma_a +q\gamma_b},$$ with $$\gamma_x=1/\sqrt{1-||x||^2}$$ the Lorentz factor. The analogue of “parallel lines” here resides in that we use the same $$(p,q)$$ for $$x$$ and $$y$$. Then, I can prove that $$\dfrac{\sinh d(x’,0)}{\sinh d(x,x’)}= \dfrac{\sinh d(y’,0)}{\sinh d(y,y’)},$$ and I can also prove using hyperbolic sine law hat $$$$\sinh d(x’,y’) \leq\min \left(\dfrac{\sinh d(x’,0)}{\sinh d(x,0)}\dfrac{\sin \alpha}{\sin \alpha’},\dfrac{\sinh d(y’,0)}{\sinh d(y,0)}\dfrac{\sin \beta}{\sin \beta’} \right)\sinh d(x,y).$$$$ and I want to prove that either $$\dfrac{\sin \alpha}{\sin \alpha’} \leq 1$$ or $$\dfrac{\sin \beta}{\sin \beta’}\leq 1$$. Here $$\alpha,\beta$$ are the angles at $$x$$ and $$y$$ in $$Oxy$$, and $$\alpha’,\beta’$$ at $$x’$$ and $$y’$$ in $$Ox’y’$$.

Exploiting negative curvature, I could already prove that $$\alpha+\beta < \alpha’+\beta’$$, but that’s not enough…

I would also be happy with a proof that Einstein midpoint operations are contracting (in $$\sinh$$ of distance), when we use the same weights $$(p,q)$$.
