Time-triggered Ethernet (TTE) is used in spacecraft, basically to use the same hardware to process traffic with different timing and criticality. Researchers have defeated it: On Tuesday, researchers published findings that, for the first time, break TTE’s isolation guarantees. The result is PCspooF, an attack that allows a single non-critical device connected to a single … Read More “Successful Hack of Time-Triggered Ethernet” »

This is a new vulnerability against Apple’s M1 chip. Researchers say that it is unpatchable. Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory, however, have created a novel hardware attack, which combines memory corruption and speculative execution attacks to sidestep the security feature. The attack shows that pointer authentication can be defeated without leaving … Read More “M1 Chip Vulnerability” »
Matt Blaze tested a variety of Faraday cages for phones, both commercial and homemade. The bottom line: A quick and likely reliable “go/no go test” can be done with an Apple AirTag and an iPhone: drop the AirTag in the bag under test, and see if the phone can locate it and activate its alarm … Read More “Testing Faraday Cages” »
Rowhammer is an attack technique involving accessing — that’s “hammering” — rows of bits in memory, millions of times per second, with the intent of causing bits in neighboring rows to flip. This is a side-channel attack, and the result can be all sorts of mayhem. Well, there is a new enhancement: All previous Rowhammer … Read More “New Rowhammer Technique” »
There’s new research that demonstrates security vulnerabilities in all of the AMD and Intel chips with micro-op caches, including the ones that were specifically engineered to be resistant to the Spectre/Meltdown attacks of three years ago. Details: The new line of attacks exploits the micro-op cache: an on-chip structure that speeds up computing by storing … Read More “New Spectre-Like Attacks” »
This report is six months old, and I don’t know anything about the organization that produced it, but it has some alarming data about router security. Conclusion: Our analysis showed that Linux is the most used OS running on more than 90% of the devices. However, many routers are powered by very old versions of … Read More “Router Security” »
Together with Nate Kim (former student) and Trey Herr (Atlantic Council Cyber Statecraft Initiative), I have written a paper on IoT supply chain security. The basic problem we try to solve is: how to you enforce IoT security regulations when most of the stuff is made in other countries? And our solution is: enforce the … Read More “Securing the International IoT Supply Chain” »
Remember Spectre and Meltdown? Back in early 2018, I wrote: Spectre and Meltdown are pretty catastrophic vulnerabilities, but they only affect the confidentiality of data. Now that they — and the research into the Intel ME vulnerability — have shown researchers where to look, more is coming — and what they’ll find will be worse … Read More “Another Intel Speculative Execution Vulnerability” »
Used Tesla components, sold on eBay, still contain personal information, even after a factory reset. This is a decades-old problem. It’s a problem with used hard drives. It’s a problem with used photocopiers and printers. It will be a problem with IoT devices. It’ll be a problem with everything, until we decide that data deletion … Read More “Used Tesla Components Contain Personal Information” »
There’s a vulnerability in Wi-Fi hardware that breaks the encryption: The vulnerability exists in Wi-Fi chips made by Cypress Semiconductor and Broadcom, the latter a chipmaker Cypress acquired in 2016. The affected devices include iPhones, iPads, Macs, Amazon Echos and Kindles, Android devices, and Wi-Fi routers from Asus and Huawei, as well as the Raspberry … Read More “Wi-Fi Chip Vulnerability” »
