File-Squatting Exploitation by Example

This will (hopefully) be a short story about a bug I found some time ago while auditing a .NET service from an OEM. It should be interesting as I have yet to find a description of how to exploit a similar condition. Our service was running as SYSTEM and needed to periodically execute some other utilities as part of its workflow. Before running these auxiliary tools, it would check if the executable was properly signed by the vendor. Something like this: public void CallAgent() {    string ExeFile = “C:\\Program…

A Reverse Engineer’s Perspective on the Boeing 787 ‘51 days’ Airworthiness Directive

Several weeks ago, international regulators announced that they were ordering Boeing 787 operators to completely shut down the plane’s electrical power whenever it had been running for 51 days without interruption.1 The FAA published an airworthiness directive elaborating on the issue, and I was curious to see what kind of details were in this document. While I eventually discovered that there wasn’t much information in the FAA directive, there was just enough to put me on track to search for the root cause of the issue. This blog post will…

Mismatch? CVSS, Vulnerability Management, and Organizational Risk

I’ll never forget a meeting I attended where a security engineer demanded IT remediate each of the 30,000 vulnerabilities he had discovered. I know that he wasn’t just dumping an unvetted pile of vulnerabilities on IT; he’d done his best to weed out false-positive results, other errors, and misses before presenting the findings. These were real issues, ranked using the Common Vulnerability Scoring System (CVSS). There can be no doubt that in that huge (and overwhelming) pile were some serious threats to the organization and its digital assets. The reaction…

10 Laws of Disclosure

In my 20+ years working in cyber security, I’ve reported more than 1000 vulnerabilities to a wide variety of companies, most found by our team at IOActive as well as some found by me. In reporting these vulnerabilities to many different vendors, the response (or lack thereof) I got is also very different, depending on vendor security maturity. When I think that I have seen everything related to vulnerability disclosures, I’ll have new experiences – usually bad ones – but in general, I keep seeing the same problems over and…

Do You Blindly Trust LoRaWAN Networks for IoT?

Do you blindly trust that your IoT devices are being secured by the encryption methods employed by LoRaWAN? If so, you’re not alone. Long Range Wide Area Networking (LoRaWAN) is a protocol designed to allow low-power devices to communicate with Internet-connected applications over long-range wireless connections. It’s being adopted by major organizations across the world because of its promising capabilities. For example, a single gateway (antenna) can cover an entire city, hundreds of square miles. With more than 100 million LoRaWAN-connected devices in use across the globe, many cellular carriers…

Supply Chain Risks Go Beyond Cyber: Focus on Operational Resilience

In this first, of a two-part blog series on supply chain, I’ll discuss the security and operational risk in today’s supply chain. In the past 20 years, we’ve seen the globalization of the supply chain and a significant movement to disperse supply chains outside national borders. With this globalization comes many supply chain risks — risks that go beyond just cyber attacks and demonstrate a need for stronger operational resilience. Most organizations want to take advantage of tariff treaties and overall cost savings by outsourcing the manufacturing and production of…

Internet of Planes: Hacking Millionaires’ Jet Cabins

The push to incorporate remote management capabilities into products has swept across a number of industries. A good example of this is the famous Internet of Things (IoT), where modern home devices from crockpots to thermostats can be managed remotely from a tablet or smartphone. One of the biggest problems associated with this new feature is a lack of security. Unfortunately, nobody is surprised when a new, widespread vulnerability appears in the IoT world. However, the situation becomes a bit more concerning when similar technologies appear in the aviation sector….

Multiple Vulnerabilities in Android’s Download Provider (CVE-2018-9468, CVE-2018-9493, CVE-2018-9546)

Android’s Download Provider is a component of the Android framework and is designed to handle external downloads for other applications, such as web browsers (including Google Chrome), email clients (including Gmail), and the Google Play Store, among many others. In this blog post, I’ll describe three different high-severity vulnerabilities which affected several of the most recent versions of Android. Android’s Download Provider Any app can delegate its external downloads through this provider. As a developer, you’ll only need to insert a row with the appropriate parameters (invoking the Download Content…

RSA Conference Requires Changes

For many years, IOActive has been hosting our IOAsis event as a refuge from the madness of crowds and marketing pitches. This was a hugely successful event and we appreciate everyone’s support and participation over the years to make it a high-quality “hallway con” in an upscale environment. Last year, we noticed a reduction in the quality of attendance at our event even though there was an increase in overall RSA Conference (RSAC) attendance. We discovered in talking to our clients, friends and peers in the industry that many of…

Arm IDA and Cross Check: Reversing the 787’s Core Network

IOActive has documented detailed attack paths and component vulnerabilities to describe the first plausible, detailed public attack paths to effectively reach the avionics network on a 787, commercial airplane from either non-critical domains, such as Passenger Information and Entertainment Services, or even external networks.
