Hacking Robots Before Skynet
Robots are going mainstream in both private and public sectors – on military missions, performing surgery, building skyscrapers, assisting customers at stores, as healthcare attendants, as business assistants, and interacting closely with our families in a myriad of ways. Robots are already showing up in many of these roles today, and in the coming years they will become an ever more prominent part of our home and business lives. But similar to other new technologies, recent IOActive research has found robotic technologies to be highly insecure in a variety of…
Harmful prefetch on Intel
We’ve seen a lot of articles and presentations that show how the prefetch instruction can be used to bypass modern OS kernel implementations of ASLR. Most of the public work however only focuses on getting base addresses of modules with the idea of building a ROP chain or maybe patching some pointer/value of the data section. This post represents an extension of previous work, as it documents the usage of prefetch to discover PTEs on Windows 10. You can find the code I used and perform the tests in…
In Flight Hacking System
In my five years with IOActive, I’ve had the opportunity to visit some awesome places, often thousands of kilometers from home. So flying has obviously been an integral part of my routine. You might not think that’s such a big deal, unless like me, you’re afraid of flying. I don’t think I can completely get rid of that anxiety; after dozens of flights my hands still sweat during takeoff, but I’ve learned to live with it, even enjoying it sometimes…and spending some flights hacking stuff. What helped a lot to…
Security Vulnerabilities in Routers
The LB-LINK BL-WR2000 router, manufactured in China and sold world-wide, contains a critical vulnerability that allows an attacker to extract the admin credentials from the login page and gain access to the web admin interface. IOActive has identified 3 high to critical vulnerabilities in the product. An attacker could exploit these issues to fully compromise the device.
Let’s Terminate XML Schema Vulnerabilities
XML eXternal Entity (XXE) attacks are a common threat to applications using XML schemas, either actively or unknowingly. That is because we continue to use XML schemas that can be abused in multiple ways. Programming languages and libraries use XML schemas to define the expected contents of XML documents, SAML authentications or SOAP messages. XML schemas were intended to constrain document definitions, yet they have introduced multiple attack avenues. XML parsers should be prepared to manage two types of problematic XML documents: malformed files and invalid files. Malformed files do…
Five Attributes of an Effective Corporate Red Team
After talking recently with colleagues at IOActive as well as some heads of industry-leading red teams, we wanted to share a list of attributes that we believe are key to any effective Red Team. [ NOTE: For debate about the relevant terminology, we suggest Daniel’s post titled The Difference Between Red, Blue, and Purple Teams. ] To be clear, we think there can be significant variance in how Red Teams are…
Multiple Vulnerabilities in BHU WiFi “uRouter”
A Wonderful (and !Secure) Router from China The BHU WiFi uRouter, manufactured and sold in China, looks great – and it contains multiple critical vulnerabilities. An unauthenticated attacker could bypass authentication, access sensitive information stored in its system logs, and in the worst case, execute OS commands on the router with root privileges. In addition, the uRouter ships with hidden users, SSH enabled by default and a hardcoded root password…and injects a third-party JavaScript file into all users’ HTTP traffic. In this blog post, we cover the main security issues…
Securing the Connected Car: Commonalities in Vehicle Vulnerabilities
With the Connected Car becoming commonplace in the market, vehicle cybersecurity grows more important by the year. At the forefront of this growing area of security research, IOActive has amassed real-world vulnerability data illustrating the general issues and potential solutions to the cybersecurity issues facing today’s vehicles. This paper explains the differences in testing methodologies, with recommendations on the most appropriate methods for testing connected vehicle systems. Detailed findings follow, including the impact, likelihood, overall risk, and remediation of vulnerabilities IOActive consultants have discovered over the course of thousands of…
Multiple Vulnerabilities in D-Link DCS-5009L IP Camera
The D-Link DCS-5009L IP Camera can be used to remotely monitor your home. It can be accessed via the D-Link Cloud or configured to upload recordings to an FTP server, as well as send notifications by email. The DCS-5009L can rotate and tilt, and has night vision and movement detection. IOActive has identified four high-risk and two low-risk vulnerabilities in the D-Link DCS-5009L IP Camera. An attacker could exploit these issues to fully compromise the confidentiality, integrity, and availability of the product.
Assessing and Exploiting XML Schema’s Vulnerabilities
Specifications for XML and XML schemas include multiple security flaws. At the same time, these specifications provide the tools required to protect XML applications. This provides a complex scenario for developers, and a fun environment for hackers. Even though we use XML schemas to define the security of XML documents, we also use them to perform a variety of attacks: file retrieval, server side request forgery, port scanning, or brute forcing. This talk will analyze how to infer new attack vectors by analyzing the current vulnerabilities, and how it is…
