M1 Chip Vulnerability

2022-06-15T07:15:19-04:00Security|

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 [...]

Hacking Tesla’s Remote Key Cards

Despite it using AES as its algorithm, it’s implementation is flawed in multiple ways—and breakable. The moral is, as it always is, that implementing cryptography securely is hard. Don’t roll your own anything if you can help it.

Me on Public-Interest Tech

2022-06-03T15:14:16-04:00Security|

Back in November 2020, in the middle of the COVID-19 pandemic, I gave a virtual talk at the International Symposium on Technology and Society: “The Story of the Internet and How it Broke Bad: A Call for Public-Interest Technologists.” It was something I was really proud of, and it’s finally up on the net.
