In This document, we download one vulnerable machine VM image and start analysis on the machine and get root privileged.
Secure coding is the practice of developing computer software in a way that guards against the accidental introduction of security vulnerabilities. Defects, bugs and logic flaws are consistently the primary cause of commonly exploited software vulnerabilities. Through the analysis of thousands of reported vulnerabilities, security professionals have discovered that most vulnerabilities stem from a relatively small number of common software programming errors. By identifying the insecure coding practices that lead to these errors and educating developers on secure alternatives, organizations can take proactive steps to help significantly reduce or eliminate vulnerabilities in software before deployment.

В последнее время все чаще происходят сложные целенаправленные атаки (APT) с использованием скрытой загрузки. Существующие системы автоанализа, как правило, не способны анализировать вредоносное ПО, используемое для APT-атак, и исследователи вредоносного ПО вынуждены анализировать его вручную. Докладчик представит новую систему автоанализа памяти в режиме реального времени (Malware Analyst). Данная система не генерирует дамп памяти при помощи LibVMI, а имеет непосредственный доступ в память для ускорения диагностики и четко распознает подозрительное поведение вредоносного ПО.
Внедрение безопасности в веб-приложениях в среде выполненияPositive Hack Days
В данной работе рассматриваются результаты исследования по реализации алгоритма исправления ошибок в приложении в среде выполнения. Исследование проводилось на приложении с незащищенным кодом с целью его защиты от внедрения кода и других уязвимостей веб-приложений. Также в работе будет представлена технология защиты веб-приложений нового поколения под названием Runtime Application Self-Protection (RASP) (самозащита приложения в среде выполнения), которая защищает от веб-атак, работая внутри веб-приложения. Технология RASP основана на исправлении ошибок в среде выполнения путем «внедрения» безопасности в веб-приложения в неявном виде, без внесения дополнительных изменений в код. В завершении доклада перечисляются основные проблемы при реализации этой новой технологии и обзор перспектив защиты среды выполнения.

Big problems with big data – Hadoop interfaces securitySecuRing
Did "cloud computing" and "big data" buzzwords bring new challenges for security testers?
Apart from complexity of Hadoop installations and number of interfaces, standard techniques can be applied to test for: web application vulnerabilities, SSL security and encryption at rest. We tested popular Hadoop environments and found a few critical vulnerabilities, which for sure cast a shadow on big data security.

OWASP - Open Web Applications Security Project to fundacja której celem jest eliminacja problemów bezpieczeństwa aplikacji. OWASP działa w duchu "open source" i dostarcza narzędzi, informacji i wiedzy pozwalających podnieść poziom bezpieczeństwa aplikacji. W trakcie wykładu przedstawię krótko OWASP Top 10 w wydaniu dla programistów, czyli "Top 10 Proactive Controls" a więc najważniejsze zalecenia pozwalające na uniknięcie kluczowych błędów bezpieczeństwa.
The security of an application is a continuous struggle between solid proactive controls and quality in SDLC versus human weakness and resource restrictions. As the pentester's experience confirms, unfortunatelly even in high-risk (e.g. banking) applications, developed by recognized vendors, the latter often wins - and we end up with critical vulnerabilities.
One of the primary reasons is lack of mechanisms enforcing secure code by default, as opposed to manual adding security per each function. Whenever the secure configuration is not default, there will almost inevitably be bugs, especially in complex systems.
I will pinpoint what should be taken into consideration in the architecture and design process of the application. I will show solutions that impose security in ways difficult to circumvent unintentionally by creative developers. I will also share with the audience the pentester's (=attacker's) perspective, and a few clever tricks that made the pentest
(=attack) painful, or just rendered the scenarios irrelevant.
With the right skills, tools and software, you can protect yourself and remain secure. This session will take attendees from no knowledge of open source web security tools to a deep understanding of how to use them and their growing set of capabilities.

[CB20] Operation I am Tom: How APT actors move laterally in corporate network...CODE BLUE
TeamT5 has helped many cyber-attack victims defending against APT actors for years. We see enormous cases showing that the actors still maintained their access to the victim network after some malware cleaning by unexperienced network managers or immature security teams. The main reason would be lacking knowledge regarding threat actors’ techniques in lateral movement operations. For example, Microsoft Windows Active Directory plays a key role and dominates most corporate network environments for centralized management and authentication. However, there are many scenarios of improper security settings would cause Active Directory attacks to become a convenient way for threat actors to move around.
In this talk, we are going to present lateral movement methods to penetrate corporate network environment and techniques to bypass security monitoring systems. All cases are based on our real experiences fighting with APT actors in recent years. We categorize them into 4 categories and list the items as below:
1.AD Farm's penetration technique: mimilib, MemSSP, skeleton key, ACL abuse
2.Web-shell technique: IIS module abuse, Web source code injection, Deserialization, Rootkit
3.Second Tier backdoor techniques: DLL-hijack, IAT insert, Port reuse
4.Miscellaneous technique: how actors moving laterally in your network without malware or hacking tools.
The target audiences of this talk include security researchers, antivirus vendors, SOC team analyst and incident response teams. The techniques disclosed in this talk would help and facilitate blue team members to detect and understand threat actors’ footprints inside a corporate network and effectively block their activities.
This version of Virtually Pwned was first presented at Black Hat US 2010. It contains details on the attacks to VMware and the pentesting approach to pentesting virtualized environments.
Hacking Highly Secured Enterprise Environments by Zoltan BalazsShakacon
In theory, post-exploitation after having remote access is easy. Also in theory, there is no difference between theory and practice. In practice, there is. Imagine a scenario, where the hacker/penetration-tester has deployed a malware on a user's workstation, but the target information is on a secure server accessed via two-factor authentication, with screen access only (e.g. RDP, Citrix, etc.) On top of that, the server runs application white-listing, and only the inbound port to the screen server (e.g. 3389) is allowed through the hardware firewall. But you also need persistent interactive C&C communication (e.g. Netcat, Meterpreter, RAT) to this server through the user's workstation.
I developed (and will publish) two tools that help the community in these situations. The first tool can drop malware to the server through the screen while the user is logged in. The second tool can help to circumvent the hardware firewall after one can execute code on the server with admin privileges (using a signed kernel driver). My tools have been tested against Windows server 2012 and Windows 8, and they work with RDP or other remote desktops (e.g. Citrix). The number of problems one can solve with them are endless, e.g., communicating with bind-shell on webserver behind restricted DMZ. Beware, live demo and fun included!

Attack web applications by using SQL attacks, CSRF, XSS. You will learn how to extract information by generating API json / xml and how to use cookies to code injection.
In an interconnected world, companies need to be able to integrate their MQTT broker into existing enterprise applications and services. One way to do so is to use an MQTT broker that can be extended by custom functionality. HiveMQ has a powerful integration SDK for doing this. The HiveMQ extension SDK provides an open API that enables developers to create custom extensions that suit their specific infrastructures. The extension framework can be used to enrich HiveMQ with custom business logic or to integrate virtually any system into HiveMQ. In this webinar, our experts will clarify the motivational drivers for building custom extensions and give an introduction to the HiveMQ extension SDK. Using an example, they will also live-demonstrate how to develop, debug, and test a custom HiveMQ extension.

1.Wireless Communication System_Wireless communication is a broad term that i...JeyaPerumal1
Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

Kioptrix: 2014 (#5)
This is Vulnhub Vulnerable machine series, In this session we find the root access of this machine.
Download VM :
https://www.vulnhub.com/entry/kioptrix-2014-5,62/
About :
As usual, this vulnerable machine is targeted at the beginner. It's not meant for the seasoned pentester or
security geek that's been at this sort of stuff for 10 years. Everyone needs a place to start and all I want to do is
help in that regard.
Also, before powering on the VM I suggest you remove the network card and re-add it. For some oddball
reason it doesn't get its IP (well I do kinda know why but don't want to give any details away). So just add the
VM to your virtualization software, remove and then add a network card. Set it to bridge mode and you should
be good to go.
This was created using ESX 5.0 and tested on Fusion, but shouldn't be much of a problem on other platforms.
Kioptrix VM 2014 download 825Megs

Waist line 32"
p.s.: Don't forget to read my disclaimer..
Hacking Step :
How to get VM IP :
Use “netdiscover -r 192.168.2.89” Command in your Kali linux box
Note : Check Screen shot Tab
Enumeration :
Get Open ports information in target machine, for that we used nmap command for enumerate
open port details and running services with version number. We also get running OS detail.
Note : Check Screen shot Tab
Web Server Port :
We found web server port 80 and 8080, Now we open running web server in our kali machine. with
80 port we get “it Works” web server but when we use 8080 port, it give error like 403.
Now we open web server of target machine with “80” port, and check source information of page.
we can see following lines,
2. <META HTTP-EQUIV="refresh"
CONTENT="5;URL=pChart2.1.3/index.php">
In this lines you can see “pchart2.1.3” word. Now you can check this word with “searchsploit” and
find any vulnerability available in this application.
http://192.168/pChart2.1.3/examples/index.php?
Action=View&Script=%2f..%2f..%2fetc/passwd
We found above LFI vulnerability in this application, using this vulnerability we can get system details.
with above command we ca get system /etc/passwd file information.
But Now we want to get 8080 port virtual host hosting details, which details available
in /usr/local/etc/apache22/httpd.conf file.
Open this file with LFI vulnerability. like
http://192.168.2.89/pChart2.1.3/examples/index.php?
Action=View&Script=%2f..%2f..
%2fusr/local/etc/apache22/httpd.conf
We found the server running on 8080 with different user-agent. “User-Agent:Mozilla/4.0"
Note : Check Screen shot Tab
Access 8080 hosted web server :
Use following command for access 8080 hosted web server with specific user-agent.
curl -H "User-Agent:Mozilla/4.0" http://192.168.1.68:8080
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<html>
<head>
<title>Index of /</title>
</head>
<body>
<h1>Index of /</h1>
<ul><li><a href="phptax/"> phptax/</a></li>
</ul>
</body></html>
Finally we get above output, In this output you can see one line “href=“phptax”. you can search
exploit for this phptax application using searchsploit command. and found one metasploit exploit.
Note : Check Screen shot Tab
Get Shell using Metasploit :
3. Now we have shell with web-root user permission. But our goal is to get root access. Using uname
command you can get running operating system and version and patch details.
Note : Check Screen shot Tab
Get Root Privilege Access :
Now we have some of target machine information, like In target machine “FreeBSD” OS running and
version is 9.0. Now use searchsploit command to find root privilege access exploit details.
Now found one exploit “28718.c” using searchsploit command.
Note : Check Screen shot Tab
