MS-SQL Post-exploitation In-depth Workshop Registration Open!

MS-SQL Post-exploitation In-depth Workshop:

The MS-SQL Post-exploitation In-depth workshop demonstrates the tactics an attacker can employ to maintain persistence in a Microsoft SQL Server database, while harnessing the available facilities to expand their influence in an environment. Plenty of resources exist today that show methods for compromising SQL and SQL-dependent applications to achieve access to the environment, very few provide methods for maintaining control of a SQL instances or performing attacks against the host and environment from within the SQL service.

This course will offer attendees an understanding of the various facilities that are available for executing system level commands, scripting, and compiling code… all from inside the SQL environment, once privileged access has been acquired. Students will walk away from this two-day course with a greater understanding of:

  • MS-SQL specific functionality
  • Stored procedures
  • Extended stored procedures
  • SQL assemblies
  • SQL agent
  • SQL internals
  • Conducting attacks and assessments from inside the SQL environment
  • Methods employed for stealth inside of SQL

Upon the completion of this workshop, attendees will:

  • Be familiar with multiple facilities in the SQL Server environment for executing system commands.
  • Understand ways to execute arbitrary code and scripts from within the database.
  • Understand methods for operating with stealth in the SQL service.
  • Know ways an attacker can rootkit or backdoor the SQL service for persistence.
  • Be familiar with hooking internal SQL functions for data manipulation.
  • Harvest credentials and password hashes of the SQL server.
  • Have familiarity with the extended stored procedure API.
  • Be able to create and deploy SQL assemblies.
  • Have the ability to impersonate system and domain level users for performing escalation in the environment.

Attendee requirements for this workshop:

  • Modern laptop with wired or wireless networking capabilities.
  • Ability to use Microsoft remote desktop from their system.
  • Basic understanding of the T-SQL language and syntax.
  • Ability to follow along with coding/scripting concepts (coding experience a plus, but not required – languages include: C, C++, C#, vbscript, jscript, and powershell)
  • Ability to navigate Visual Studio and OllyDBG (previous experience a plus, but not required.)

Attendees will be provided with:

  • Hosted VMs for testing and workshop labs.
  • Training materials – presentation materials and lab examples.

Who should attend this workshop?

  • SQL administrators and security personnel.
  • Professional pen-testers and corporate security team members.
  • Incident response analysts for new methods of attack detection.
  • Forensic team members unfamiliar with SQL related attack patterns.
  • Anyone interested in furthering their understanding of SQL Server.

Let the Hackers Learn

Schools don’t teach hacking, and the internet hides it for both profit, and fear of punishment. This makes learning, in a legal way, very difficult; so we developed a site where anyone can create any security related challenge they want. This talk is about how we keep our server safe and secure while letting our users make any mistake they want so they can teach the world about all the web based exploits.

Adventures with weird machines thirty years after “Reflections on Trusting Trust”

It’s been thirty years since Ken Thompson’s famous “Reflections on Trusting Trust” (well, 29, but what’s an off-by-one?). Back then, few hackers expected to actually encounter a planted bug, and now we speculate what commonly used software might not have them. But, if we somehow managed to eliminate all bugs, could we then trust software? We believe that the answer is “not really”: bugs are a part of the problem but by far not all of it.

Any complex enough input is indistinguishable from bytecode for a “weird” virtual machine hiding in the parser. Unless we radically redesign data formats, telling what data could do when fed to software is much harder than it needs to be. For code, of course, it’s known to be undecidable, but it may surprise you how many “tables” are as good as code: for example, so are ELF relocations + dynamic symbols, and so are IDT+GDT+TSS for an ia32 processor (no instructions needed for a Turing-complete computation). This talk will summarize two years of our explorations with @BxSays and @JulianBangert of such “weird machine” programming environments, and what these weird machines mean for “Trusting Trust” beyond bugs.

Sergey Bratus
Sergey Bratus believes that hacking has become a distinct computing research and engineering discipline: while academia focuses on abstractions, models, and frameworks, hackers expose “weird machines” inside actual systems, and show how much unexpected computation power they are capable of. On his day job as a Research Assistant Professor at Dartmouth College, he is extremely fortunate to work with brilliant students who hack ELF, DWARF, 802.11, 802.15.4, and many other nice things.

Static Malware Analysis with PyTriage

Malware analysis is a long process. It’s also not a very well known process among most IT professionals. In some corporate environments a dedicated malware analyst might not be available. In that case, one of the available IT staff might need to perform some preliminary analysis on the binary. It is for this reason PyTriage is available.

This tool provides a simple to use interface to perform preliminary static analysis of the binary. One of it’s features is to generate hashes in a variety of standards. Currently it supports MD5, SHA1 and sshdeep but more can be added quite easily. It also supports file type recognition with “file magic” technique so one can be sure of the type of the file before starting detailed analysis. PyTriage also has some PE dissection capabilities. It splits the PE into required sections and then displays the section information along with it’s hash and size. One can also peek into the imported DLLs as well as the exported functions which will hint at the possible usage of the binary. It can also generate signatures in two different formats: One for the open source malware analysis tool YARA and the other for the popular antivirus ClamAV. PyTriage also has support for submitting the file via the VirusTotal API. This allows you to look up if the file has been detected previously by antivirus providers. There is also a report generation feature that allows you to generate a concise report.

All of this is available with an easy to use GUI so newcomers to malware analysis can find analysis easy. The presentation will also take a look at how one can write plugins for the tool so as to contribute and make it a better tool.

Abusing Google Apps: Google is my Command and Control Center

This talk is about abusing Google Apps to implement various attacks that ranges from Hostless Phishing to setting up a Botnet’s Command & Control Center. In this talk i will demonstrate the implementation of Hostless Phishing, the rebirth of age old e-mail bombing, and finally implementing a cross platform (Windows, Linux, Mac) bot in python that uses Google Apps as it’s C&C. The Bot and C&C communication is done via Layer 7. The Botnet’s commands and responses are encrypted with Google’s own SSL connection.

This talk will give the audience an idea about how the innocent Google services can be abused by an attacker.

Hacking and Reverse Engineering Industrial Control Systems with DOSBox

The reality of finding MS-DOS, Windows 3.1, 95, 98, NT, 2000, etc as the controlling operating system on many industrial and SCADA control systems is all too common. To most, these systems have become a lost art that confounds those who are tasked with supporting these, unless the machine or system is under service agreement. Having systems with these operating systems is a huge threat to your infrastructure. This presentation will provide solutions for enumerating and dealing with legacy platforms including discovery, reverse engineering, emulation, and thoughts on new technology.

d4rkm4tter has a degree in Computer Science with emphasis on computer security. He has 9 years industry experience which ranges from running Internet companies (ISP and SaaS), consulting for government agencies, designing/implementing SCADA/Industrial Control systems for transit, commercial to now working with Sylarus Technologies where he is primarily focused on improving antiquated hardware and software as well as protecting intellectual property and the manufacturing machines. He is passionate hacker who is focused on innovation.

Are you Janitor or a Cleaner?

Everyday corporations are faced with the increasing likelihood of attack. They spend millions, in security software/tools/training/hardware only to neuter it at the behest of other “business” units. The idea that losing one customer because of a false positive is enough justification to put the entire customer base at risk. This talk will debunk that myth, as well as show what makes our attackers so nimble ( they don’t have to play by the rules ). On the flip side – how are you handling the breech? What are you doing with your attack data? Are you just mopping up the mess – or are you armed with the tools to thoroughly “clean” your enemy. This talk is a double shot of the real life experiences handling an active attack and cleaning up after a breach. A primer on new approaches to antiquated techniques and ultimately shine some light on what makes the attacker so nimble – and ways to up your incident response game. Are you a janitor? Or are you a cleaner?

Mask Your Checksums – The Gorry Details

When publicly submitting packet data, it is common wisdom to mask things such as your IP addresses. It is also advised that you mask your checksums, why? This talk attempts to beat this dead horse to the ground, with demonstrations and an open-source tool release.
