The winner of the Best Paper Award at Crypto this year was a significant improvement to lattice-based cryptanalysis. This is important, because a bunch of NIST’s post-quantum options base their security on lattice problems. I worry about standardizing on post-quantum algorithms too quickly. We are still learning a …
The paperback version of A Hacker’s Mind has just been published. It’s the same book, only a cheaper format. But—and this is the real reason I am posting this—Amazon has significantly discounted the hardcover to $15 to get rid of its stock. This is much …
Molly White—of “ Web3 is Going Just Great ” fame— reviews Chris Dixon’s blockchain solutions book: Read Write Own : In fact, throughout the entire book, Dixon fails to identify a single blockchain project that has successfully provided a non-speculative service at any kind of scale. The closest he ever …
Matt Burgess tries to only use passkeys. The results are mixed. [...]
Amusing story about a penguin named “Squid.” As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered. Read my blog posting guidelines here. [...]
The widely reported story last week that 1.5 million smart toothbrushes were hacked and used in a DDoS attack is false. Near as I can tell, a German reporter talking to someone at Fortinet got it wrong, and then everyone else ran with it without reading the German …
Over on Lawfare, Jim Dempsey published a really interesting proposal for software liability: “Standard for Software Liability: Focus on the Product for Liability, Focus on the Process for Safe Harbor.” Section 1 of this paper sets the stage by briefly describing the problem to be solved. Section 2 canvasses …
Interesting research: “ Sleeper Agents: Training Deceptive LLMs that Persist Through Safety Training “: Abstract: Humans are capable of strategically deceptive behavior: behaving helpfully in most situations, but then behaving very differently in order to pursue alternative objectives when given the opportunity. If an AI system learned such a deceptive strategy …
Via a FOIA request, we have documents from the NSA about their banning of Furby toys. [...]
A deepfake video conference call—with everyone else on the call a fake— fooled a finance worker into sending $25M to the criminals’ account. [...]
Argentina is reporting that there is a good population of illex squid in its waters ready for fishing, and is working to ensure that Chinese fishing boats don’t take it all. As usual, you can also use this squid post to talk about the security stories in the …
David Kahn has died. His groundbreaking book, The Codebreakers was the first serious book I read about codebreaking, and one of the primary reasons I entered this field. He will be missed. [...]
February 2, 2024: We’ve updated this post to fix broken links and added a note on migrating passwords. Customers often ask us how to migrate their on-premises Active Directory (AD) domain to AWS so they can be free of the operational management of their AD infrastructure. Frequently they …
In 2009, I wrote : There are several ways two people can divide a piece of cake in half. One way is to find someone impartial to do it for them. This works, but it requires another person. Another way is for one person to divide the piece, and the …
Consumer Reports is reporting that Facebook has built a massive surveillance network: Using a panel of 709 volunteers who shared archives of their Facebook data, Consumer Reports found that a total of 186,892 companies sent data about them to the social network. On average, each participant in the …
In October, the Consumer Financial Protection Bureau (CFPB) proposed a set of rules that if implemented would transform how financial institutions handle personal data about their customers. The rules put control of that data back in the hands of ordinary Americans, while at the same time undermining the data …
GCHQ has released new images of the WWII Colossus code-breaking computer, celebrating the machine’s eightieth anniversary (birthday?). News article. [...]
It finally admitted to buying bulk data on Americans from data brokers, in response to a query by Senator Weyden. This is almost certainly illegal, although the NSA maintains that it is legal until it’s told otherwise. Some news articles. [...]
Microsoft is reporting that a Russian intelligence agency—the same one responsible for SolarWinds—accessed the email system of the company’s executives. Beginning in late November 2023, the threat actor used a password spray attack to compromise a legacy non-production test tenant account and gain a foothold, and …
Amazing footage of a black-eyed squid ( Gonatus onyx ) carrying thousands of eggs. They tend to hang out about 6,200 feet below sea level. As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered. Read my …
For most of history, communicating with a computer has not been like communicating with a person. In their earliest years, computers required carefully constructed instructions, delivered through punch cards; then came a command-line interface, followed by menus and options and text boxes. If you wanted results, you needed to …
Interesting article. I am also skeptical that we are going to see useful quantum computers anytime soon. Since at least 2019, I have been saying that this is hard. And that we don’t know if it’s “land a person on the surface of the moon” hard, or …
New research into poisoning AI models : The researchers first trained the AI models using supervised learning and then used additional “safety training” methods, including more supervised learning, reinforcement learning, and adversarial training. After this, they checked if the AI still had hidden behaviors. They found that with specific prompts …
Really interesting research: “ Lend Me Your Ear: Passive Remote Physical Side Channels on PCs.” Abstract: We show that built-in sensors in commodity PCs, such as microphones, inadvertently capture electromagnetic side-channel leakage from ongoing computation. Moreover, this information is often conveyed by supposedly-benign channels such as audio recordings and common …
You can find them by searching for OpenAI chatbot warning messages, like: “I’m sorry, I cannot provide a response as it goes against OpenAI’s use case policy.” I hadn’t thought about this before: identifying bots by searching for distinctive bot phrases. [...]
