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…
GE Reason S20 Industrial Managed Ethernet Switch Multiple Vulnerabilities
The S20 Ethernet Switch is a device manufactured by GE Grid Solution which is deployed in industrial environments. This device is part of ICS/SCADA architectures. Stored XSS flaws can result in a large number of possible exploitation scenarios. With most XSS flaws, the entirety of the JavaScript language is available to the malicious user.
pppd Vulnerable to Buffer Overflow Due to a Flaw in EAP Packet Processing (CVE-2020-8597)
Due to a flaw in the Extensible Authentication Protocol (EAP) packet processing in the Point-to-Point Protocol Daemon (pppd), an unauthenticated remote attacker may be able to cause a stack buffer overflow, which may allow arbitrary code execution on the target system. This vulnerability is due to an error in validating the size of the input before copying the supplied data into memory. As the validation of the data size is incorrect, arbitrary data can be copied into memory and cause memory corruption possibly leading to the execution of unwanted code.
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…
LoRaWAN Networks Susceptible to Hacking: Common Cyber Security Problems, How to Detect and Prevent Them
LoRaWAN is fast becoming the most popular wireless, low-power WAN protocol. It is used around the world for smart cities, industrial IoT, smart homes, etc., with millions of devices already connected. The LoRaWAN protocol is advertised as having “built-in encryption” making it “secure by default.” As a result, users are blindly trusting LoRaWAN networks and not paying attention to cyber security; however, implementation issues and weaknesses can make these networks easy to hack. Currently, cyber security vulnerabilities in LoRaWAN networks are not well known, and there are no existing tools…
