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” »
I have been meaning to write about Joe Sullivan, Uber’s former Chief Security Officer. He was convicted of crimes related to covering up a cyberattack against Uber. It’s a complicated case, and I’m not convinced that he deserved a guilty ruling or that it’s a good thing for the industry. I may still write something, … Read More “The Conviction of Uber’s Chief Security Officer” »
After suffering two large, and embarrassing, data breaches in recent weeks, the Australian government increased the fine for serious data breaches from $2.2 million to a minimum of $50 million. (That’s $50 million AUD, or $32 million USD.) This is a welcome change. The problem is one of incentives, and Australia has now increased the … Read More “Australia Increases Fines for Massive Data Breaches” »

Already, previous versions of the Rubber Ducky could carry out attacks like creating a fake Windows pop-up box to harvest a user’s login credentials or causing Chrome to send all saved passwords to an attacker’s webserver. But these attacks had to be carefully crafted for specific … Read More “USB “Rubber Ducky” Attack Tool” »
Interesting research: “Sponge Examples: Energy-Latency Attacks on Neural Networks“: Abstract: The high energy costs of neural network training and inference led to the use of acceleration hardware such as GPUs and TPUs. While such devices enable us to train large-scale neural networks in datacenters and deploy them on edge devices, their designers’ focus so far … Read More “Attacking the Performance of Machine Learning Systems” »
Cloudflare is reporting a large DDoS attack against an unnamed company “operating a crypto launchpad.” While this isn’t the largest application-layer attack we’ve seen, it is the largest we’ve seen over HTTPS. HTTPS DDoS attacks are more expensive in terms of required computational resources because of the higher cost of establishing a secure TLS encrypted … Read More “15.3 Million Request-Per-Second DDoS Attack” »
