Over the last year, synchronized and coordinated attacks against critical infrastructure have taken center stage. Remote cyber intrusions at three Ukrainian regional electric power distribution companies in December 2015 left approximately 225,000 customers without power. Malware, like BlackEnergy, is being specially developed to target supervisory control and data acquisition (SCADA) systems. Specifically, adversaries are focusing their efforts on obtaining access to the human-machine...

Following recent security issues discovered in Android, Google made a number of changes to tighten security across its fragmented landscape. However, Google is not alone in the struggle to keep Android safe. Qualcomm, a supplier of 80% of the chipsets in the Android ecosystem, has almost as much effect on Android’s security as Google. With this in mind, we decided to examine Qualcomm’s code in Android devices. During our research, we found multiple privilege escalation vulnerabilities in...

Rogue access points provide attackers with powerful capabilities, but in 2016 modern privacy protections such as HTTPS Everywhere, free TLS certificates and HSTS are de-facto standards. Surely our encrypted traffic is now safe on the local coffee shop network? If not, my VPN will definitely protect me… right? In this talk we’ll reveal how recent improvements in online security and privacy can be undermined by decades old design flaws in obscure specifications. These design weakness can be...

TASBot is an augmented Nintendo R.O.B. robot that can play video games without any of the button mashing limitations us humans have. By pretending to be a controller connected to a game console, TASBot triggers glitches and exploits weaknesses to execute arbitrary opcodes and rewrite games.

As a matter of fact, it is all about time to reverse engineer the most complex piece of code. Code complicity techniques are usually used just to increase the time and effort needed for reverse engineering. The desired effect of code complicity can be magnified using mechanisms that decrease and narrow the allowed time frame for any reverse engineering attempt into few milliseconds. Such approach can be applied using a metamorphic engine that is aware of the time dimension. Beyond metamorphic...

Active Directory domain privilege escalation is a critical component of most penetration tests and red team assessments, but standard methodology dictates a manual and often tedious process – gather credentials, analyze new systems we now have admin rights on, pivot, and repeat until we reach our objective. Then — and only then — we can look back and see the path we took in its entirety. But that may not be the only, nor shortest path we could have taken. By combining our concept of...

Managed Code Rootlets (MCRs) are terrifying post-exploitation attacks that open the doors for cementing and expanding a foothold in a target network. While the concept isn’t new, practical tools for developing MCRs don’t currently exist. Ere Metula released ReFrameworker in 2010 with the ability to inject attack modules into the C# runtime, paving the way for MCRs, but the tool requires the attacker to have knowledge of intermediate languages, does not support other runtimes, and is no...

When developers have done their job well you’ll find JTAG locked-up, non-responsive serial ports, locked-down boot, and perhaps even a home brewed secure-boot solution. In this session you’ll learn details of a useful hardware/software penetration technique to attempt when you’ve run out of easier options. We’ve used this technique on two commercial device...

The main benefit of the later technique over the former being that it does work. Once achieved universal code ‘reuse’ by relinking those relocatable objects as arbitrary shared libraries, we’ll create a form of binary reflection, add scripting capabilities and in memory...

In the past few years, several tools have been released allowing hobbyists to connect to CAN buses found in cars. This is welcomed as the CAN protocol is becoming the backbone for embedded computers found in smart cars. Its use is now even spreading outside the car through the OBD-II connector: usage-based policies from insurance companies, air-pollution control from law enforcement or engine diagnostics from smartphones for instance. Nonetheless, these tools will do no more than what...

If you’re interested in vulnerability research for fun or profit, or if you’re a beginner and you’re not sure how to progress, it can be difficult to sift through the firehose of technical information that’s out there. Plus there are all sorts of non-technical things that established researchers seem to just know. There are many different things to learn, but nobody really talks about the different paths you can take on your journey. We will provide an overview of key concepts in...

The number of IMSI-catchers (rogue cell towers) has been steadily increasing in use by hackers and governments around the world. Rogue cell towers, which can be as small as your home router, pose a large security risk to anyone with a phone. If in range, your phone will automatically connect to the rogue tower with no indication to you that anything has happened. At that point, your information passes through the rogue tower and can leak sensitive information about you and your device....

The use cases for hooking code execution are abundant and this topic is very expansive. EhTracing (pronounced Tracing) is technique that allows monitoring/altering of code execution at a high rate with several distinct advantages. Full context (registers, stack & system state) hooking can be logged without needing to know a function prototype and changes to execution flow can be made as desired. Traditional detours like hooking requires a length disassembly engine than direct binary .text...

Modern web applications generate a ton of logs. Suites like ELK (Elasticsearch, Logstash, Kibana) exist to help manage these logs, and more people are turning to them for their log analysis needs. These logs contain a treasure trove of information regarding bad actors on your site, but surfacing that information in a timely manner can be difficult. When Etsy moved over from Splunk to ELK in mid-2014, we realized that ELK lacked necessary functionality for real-time alerting. We needed a...

Network telescopes are collections of unused but BGP-announced IP addresses. They collect the pollution of the Internet: scanning, misconfigurations, backscatter from DoS attacks, bugs, etc. For example, several historical studies used network telescopes to examine worm outbreaks. In this talk I will discuss phenomena that have recently induced many sources to send traffic to network telescopes. By examining this pollution we find a wealth of security-related data. Specifically, I’ll touch on...

Get mirandized for an encrypted world. This talk will cover the legal doctrines and statues our government is perverting to compel individuals into decrypting their data, or conscript technology companies into subverting the security of their own products. We’ll survey the arguments being advanced by prosecutors, the resulting case law, and the ethical dilemmas facing technology companies. The session will cover the rights and civil liberties we’ve already lost, and review the current...
