Lab3Lab3steps.docxScenario The university has caught a .docxsmile790243
Lab3/Lab3steps.docx
Scenario:
The university has caught a malware operator on campus and found a domain generating algorithm (DGA) on the campus-owned computer which this person was using. The campus has asked you to figure out how it works so that they can potentially use the command and control server for research like is described here in the attached pdf. (Attached in folder)
The file you will need to figure out is here (this is written in the computer language C, not malware) (this file is attached in folder).
One way to find out how something works is using IDA in Kali Linux information about kali can be found here: kali.org. Some basic stuff about IDA can be found here: http://securityxploded.com/reversing-basics-ida-pro.php (Links to an external site.). These resources will not be sufficient to get you all the way through the lab, because they were not designed as a step by step walkthrough of the lab, you will need to take the knowledge from these resources and others that you find to complete the lab.
I attached the exe file. You have to unzip the file. The exe file has to be run from command line (in a SAFE environment i.e. a virtual machine).
When reverse engineering the exe file, you should be looking at _dga/dga function. You can use IDA Pro. (The .exe file is attached in folder)
For this lab, you will need to: find out what you can from the files attached, following a lab report format outlined which is abstract, discussion, and conclusion. Take a lot of screenshots
Steps I’ve done:
1- I used command prompt to check the file using sigcheck tool
2- I checked in virustotal.com to see if it’s known
3- I used HxD to check the file hex-decimal and header and found “MZ”
4- I checked the file properties and information
5- I checked the file’s strings to see the codes and try to recognize some of them
6- I took a snapshot for the registry
7- I executed cdga.exe and took a second snapshot for the registry
8- I compared the two snapshots and found 193 changes
9- I used process monitor to monitor the process.

The post release technologies of Crysis 3 (Slides Only) - Stewart NeedhamStewart Needham
For AAA games now there is a consumer expectation that the developer has a post release strategy. This strategy goes beyond just DLC content. Users expect to receive bug fixes, balancing updates, gamemode variations and constant tuning of the game experience. So how can you architect your game technology to facilitate all of this? Stewart explains the unique patching system developed for Crysis 3 Multiplayer which allowed the team to hot-patch pretty much any asset or data used by the game. He also details the supporting telemetry, server and testing infrastructure required to support this along with some interesting lessons learned.
stackconf 2020 | Speeding up Linux disk encryption by Ignat KorchaginNETWAYS
Encrypting data at rest is a must-have for any modern SaaS company. And if you run your software stack on Linux, LUKS/dm-crypt [1] is the usual go-to solution. However, as the storage becomes faster, the IO latency, introduced by dm-crypt becomes rather noticeable, especially on IO intensive workloads.
At first glance it may seem natural, because data encryption is considered an expensive operation. But most modern hardware (specifically x86 and arm64) platforms have hardware optimisations to make encryption fast and less CPU intensive. Nevertheless, even on such hardware transparent disk encryption performs quite poorly.
This document provides a complete report on a penetration test using Kali Linux with a vulnerable machine available on Vulnhub.com. The Game of Thrones CTF: 1 (Capture The Flag) contains 11 flags in total (7 kingdom flags, 3 secret flags and one battle flag). The first chapter introduces a short description about cyber-risks and general IT security nowadays. The second chapter contains the setting for the laboratory in Oracle Virtual Box software to virtualize the attacker machine and the target machine. Furthermore, the subchapters are about the attack narrative, each one according to a specific
step-by-step location. Please notice that this walkthrough might contain spoilers to the actual TV series.
Ultimately, a comment about the vulnerabilities found in this challenge, some recommendations and the major consulted resources and used tools.
From the infection phase to the command & control functionalities, this talk is a 360 degrees analysis of a recent Russian botnet distribution package. Particular features of this botnet are communication over HTTP protocol and use of PHP and Mysql.
When you are designing a production environment security is essential. All the Docker ecosystem but in particular Docker Swarm allows us to ship our containers out of our laptop, how can we make this process safe? During my talk, I will share tips around production environment, immutability and how troubleshooting common attack as code injection with Docker. Static analysis of our images, content trust with Notary to make our journey secure.
How can we setup a cluster on the main cloud providers with VPN and node labeling to expose only a portion of our cluster? I will also show what Docker provides (Content Trust, Static Analysis) but also open source alternatives as Notary, centos/clair and Cilium.
In the end of this talk, we had a better idea around how manage Docker in production.
IoT (Internet of Things) and OT (Operational Technology) are the current buzzwords for networked devices on which our modern society is based on. In this area the used operating systems are summarized with the term firmware. The devices by themself, so called embedded devices, are essential in the private, as well as in the industrial environment and in the so-called critical infrastructure. Penetration testing of these systems is quite complex as we have to deal with different architectures, optimized operating systems and special protocols. EMBA is an open-source firmware analyzer with the goal to simplify and optimize the complex task of firmware security analysis. EMBA supports the penetration tester with the automated detection of 1-day vulnerabilities on binary level. This goes far beyond the plain CVE detection. With EMBA you always know which public exploits are available for the target firmware. Beside the detection of already known vulnerabilities, EMBA also supports the tester on the next 0-day. For this EMBA identifies critical binary functions, protection mechanisms and services with network behavior on a binary level. There are many other features built into EMBA, such as fully automated firmware extraction, finding file system vulnerabilities, hard-coded credentials, and more. EMBA is an open-source firmware scanner, created by penetration testers for penetration testers.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
