Introduction Today we will take a first look at malware-based attacks on ATMs in general, while future articles will go into more detail on the individual subtopics. ATMs have been robbed by criminal gangs around the world for decades. A successful approach since ~ 20 years is the use of highly flammable gas, which is … Continue reading Malware-based attacks on ATMs – A summary
As discussed in our first post in the series about our ICS firing range, we came to the conclusion that we had to build a lab ourselves. Now, this turned out to be a quite tricky task and in this blog post I am going to tell you why: which challenges we faced and which … Continue reading Building an ICS Firing Range – Part 2 (Defcon 29 ICS Village)
Wi-Fi devices are affected by a series of new attacks on the Wi-Fi protocol, known as FragAttacks and released in May 2021. These attacks have complex requirements and impacts. We attempt to shed some light on those and provide some guidance for users, developers and asset owners (integrators or IT staff).
This blog post is the last part of a series, if you are interested in the security or privacy of smart home devices, be sure to check out the other parts as well! TL;DR: In our previous blog posts we concluded that there is quite a long way to go for both security and privacy … Continue reading Smart Home Devices: assets or liabilities? – Part 3: Looking at the future
TL;DR - Part two of this trilogy of blog posts will tackle the next big topic when it comes to smart home devices: privacy. Are these devices doubling as the ultimate data collection tool, and are we unwittingly providing the manufacturers with all of our private data? Find out in this blog post! This blog … Continue reading Smart Home Devices: assets or liabilities? – Part 2: Privacy
This blog post is part of a series, keep an eye out for the following parts! TL;DR - Smart home devices are everywhere, so I tested the base security measures implemented on fifteen devices on the European market. In this blog post, I share my experience throughout these assessments and my conclusions on the overall … Continue reading Smart Home Devices: assets or liabilities? – Part 1: Security
TL;DR: We use a proof of concept script to attack a Digi Connect ME 9210 device affected by CVE-2020-11898, part of the newly-released Ripple20 series of vulnerabilities. Ripple20 In June 2020, JSOF released information about a series of 19 vulnerabilities dubbed "Ripple20". Ripple20 affects the popular Treck network stack, which is used by many connected … Continue reading Testing Ripple20: A closer look and proof of concept script for CVE-2020-11898
TL;DR: IOXY is an open source MQTT intercepting proxy, developed by NVISO for our IoT pentest needs, and now available on GitHub. Features include a GUI, live packet interception and modification and MQTTS support. The need for IOXY In the web and mobile application worlds, intercepting proxies like Burp and OWASP ZAP occupy a central … Continue reading Introducing IOXY: an open-source MQTT intercepting proxy
TL;DR: The second of our short, IoT-related posts shares a simple trick we use in IoT pentests to temporarily change the contents of read-only files in Linux-based devices. Very useful when trying to proxy network traffic or temporary change the behavior of a device! IoT field notes is a series of short stories about interesting … Continue reading IoT hacking field notes #2: Using bind mounts to temporarily modify read-only files
TL;DR: First in a new series of short, IoT-related posts, this tells the story of a simple glitching attack we used to get a bootloader shell and ultimately root a device. IoT field notes is a new series of short stories about interesting (hopefully 🙂 ) observations, vulnerabilities and techniques, inspired directly from the IoT … Continue reading IoT hacking field notes #1: Intro to glitching attacks
