kandi X-RAY | attack-review-testbed Summary
Thanks for your interest in attacking the hardened Node demo app. Hopefully seeing what security machinery resists concerted attempt by skilled attackers will help the Node community better safeguard their users' interests. This document explains how to access the target application, and what does and does not constitute a successful breach. Slow Setup Ahead: The target application is meant to be run locally on a machine you control. Setup below builds a patched node runtime from source, which takes over several minutes, so it may be worth starting that running while you browse this document. The target is a simple social-networking web application that lets users post updates. "Setup" explains how to get it up and running. "What is a breach" and "What is not a breach" explain what constitutes a successful attack. Later, there are logistical notes on how to contribute breaches or report other issues. The final section discussion explains how this effort fits into a bigger picture. The target application has an intentionally large attack surface. This application should be easy to breach if it were not for the security machinery under test, so if it resists breach, then the security machinery provides value. Specifically, the target application code does not filter inputs for dangerous patterns, does not explicitly escape outputs, calls require() with a URL path to dispatch to HTTP request handlers, and composes SQL queries and shell strings from untrusted strings without explicit escaping.

QUESTION
I am aiming to build a hardware based password manager that will store credentials like -username and passwords- externally, right now I am searching about it but I am having trouble in identifying that how will that external device integrate with browsers and websites when connected to provide the credentials stored in it. I mean what technique is used to integrate the hardware password managers to the device or browser.
I would appreciate any sort of help and guidance from your side, Thanks!
...ANSWER
Answered 2021-Apr-28 at 12:48Usually they inject passwords using a HID device acting as a keyboard. Check out the OnlyKey as an example.
The way these work is by injecting/typing username and password based on pressing a hardware button against which you have stored the relevant credentials. There is also the option to complete MFA by storing an OTP token. Some will act like any other password manager by parsing the website URL against what is stored, but I guess this opens an attack surface when feeding data back to the device.

QUESTION
I have to write the "assumptions" part of a pentest report and I am having trouble understanding what I should write. I checked multiple pentest reports (from https://github.com/juliocesarfort/public-pentesting-reports) but none of them had this paragraph.
Also I found this explanation "In case there are some assumptions that the pen-tester considers before or during the test, the assumptions need to be clearly shown in the report. Providing the assumption will help the report audiences to understand why penetration testing followed a specific direction.", but still what I do have in mind it is more suited for "attack narative".
Can you provide me a small example (for one action, situation) so I can see exactly how it should be written?
ANSWER
Answered 2021-Apr-16 at 15:25I would think the "assumptions" paragraph and the "Attack narrative" paragraph are somehow overlapping. I would use the "Assumptions" paragraph to state a couple of high level decisions made before starting the attack, with whatever little information the pentester would have on the attack. I would expand on the tools and techniques used in the "Attack narrative" paragraph
For example an assumption could be: "The pentester is carrying on the exercise against the infrastructure of a soho company with less than 5 people It is common for soho companies to use consumer networking equipment that is usually unsecure, and left configured as defualt. For this reason the attacker focused on scanning for http and ssh using a database of vendors default username and passwords"
QUESTION
I'm trying to analyse a compiled file for cybersec learning purposes and want to use a particular function.
Here is the output of nm --defined-only ./compiled_file

ANSWER
Answered 2021-Mar-09 at 12:54Yes, it is possible. The point of having exported symbols in shared libraries is to be able to use them - after all. In C, you can do this either by linking the library to the application (not really an option for python), or runtime loading the library and finding the required symbol (on linux: dlopen, dlsym). The manpage example shows how to do this in C.
QUESTION
Currently, I have set the following CSP header in the HTML file of my webpage -
...ANSWER
Answered 2020-Nov-04 at 19:09The issue was caused and fixed as follows -
The button that takes XML file as input in the HTML form has an inline event handler, which the CSP Policy was blocking, thereby blocking the upload. I moved this inline event handler to an external function and called the function. This fixed the issue and CSP is no longer blocking the function.
