New attack against the RADIUS authentication protocol: The Blast-RADIUS attack allows a man-in-the-middle attacker between the RADIUS client and server to forge a valid protocol accept message in response to a failed authentication request. This forgery could give the attacker access to network devices and services without the attacker …
Interesting : By reverse-engineering how Ticketmaster and AXS actually make their electronic tickets, scalpers have essentially figured out how to regenerate specific, genuine tickets that they have legally purchased from scratch onto infrastructure that they control. In doing so, they are removing the anti-scalping restrictions put on the tickets by …
ProPublica has a long investigative article on how the Cyber Safety Review Board failed to investigate the SolarWinds attack, and specifically Microsoft’s culpability, even though they were directed by President Biden to do so. [...]
A new vampire squid species was discovered in the South China Sea. Blog moderation policy. [...]
It’s a serious one : The vulnerability, which is a signal handler race condition in OpenSSH’s server (sshd), allows unauthenticated remote code execution (RCE) as root on glibc-based Linux systems; that presents a significant security risk. This race condition affects sshd in its default configuration. [...] This vulnerability, if …
If you’ve been reading my blog, you’ve noticed that I have written a lot about AI and democracy, mostly with my co-author Nathan Sanders. I am pleased to announce that we’re writing a book on the topic. This isn’t a book about deep fakes, or …
This article about an app that lets people remotely view bars to see if they’re crowded or not is filled with commentary—on both sides—about privacy and openness. [...]
A new paper, “Polynomial Time Cryptanalytic Extraction of Neural Network Models,” by Adi Shamir and others, uses ideas from differential cryptanalysis to extract the weights inside a neural network using specific queries and their results. This is much more theoretical than practical, but it’s a really interesting result …
A new squid species—of the Gonatidae family—was discovered. The video shows her holding a brood of very large eggs. Research paper. [...]
Longtime NSA-watcher James Bamford has a long article on the reauthorization of Section 702 of the Foreign Intelligence Surveillance Act (FISA). [...]
A group of cryptographers have analyzed the eiDAS 2.0 regulation (electronic identification and trust services) that defines the new EU Digital Identity Wallet. [...]
This move has been coming for a long time. The Biden administration on Thursday said it’s banning the company from selling its products to new US-based customers starting on July 20, with the company only allowed to provide software updates to existing customers through September 29. The ban …
Interesting paper about a German cryptanalysis machine that helped break the US M-209 mechanical ciphering machine. The paper contains a good description of how the M-209 works. [...]
Former NSA Director Paul Nakasone has joined the board of OpenAI. [...]
Beautiful astronomical photo. [...]
The memorial service for Ross Anderson will be held on Saturday, at 2:00 PM BST. People can attend remotely on Zoom. (The passcode is “L3954FrrEF”.) [...]
Interesting summary of various ways to derive the public key from digitally signed files. Normally, with a signature scheme, you have the public key and want to know whether a given signature is valid. But what if we instead have a message and a signature, assume the signature is …
There has been a lot of toxicity in the comments section of this blog. Recently, we’re having to delete more and more comments. Not just spam and off-topic comments, but also sniping and personal attacks. It’s gotten so bad that I need to do something. My options …
Culture is increasingly mediated through algorithms. These algorithms have splintered the organization of culture, a result of states and tech companies vying for influence over mass audiences. One byproduct of this splintering is a shift from imperfect but broad cultural narratives to a proliferation of niche groups, who are …
There is a lot written about technology’s threats to democracy. Polarization. Artificial intelligence. The concentration of wealth and power. I have a more general story: The political and economic systems of governance that were created in the mid-18th century are poorly suited for the 21st century. They don …
Interesting research: “ Teams of LLM Agents can Exploit Zero-Day Vulnerabilities.” Abstract: LLM agents have become increasingly sophisticated, especially in the realm of cybersecurity. Researchers have shown that LLM agents can exploit real-world vulnerabilities when given a description of the vulnerability and toy capture-the-flag problems. However, these agents still perform …
Squid humor. 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. [...]
This is a current list of where and when I am scheduled to speak: I’m appearing on a panel on Society and Democracy at ACM Collective Intelligence in Boston, Massachusetts. The conference runs from June 26 through 29, 2024, and my panel is at 9:00 AM on …
This is really neat demo of the security problems arising from reusing nonces with a symmetric cipher in GCM mode. [...]
As India concluded the world’s largest election on June 5, 2024, with over 640 million votes counted, observers could assess how the various parties and factions used artificial intelligence technologies—and what lessons that holds for the rest of the world. The campaigns made extensive use of AI …
