Why Tehran’s Two-Tiered Internet Is So Dangerous

Iran is slowly emerging from the most severe communications blackout in its history and one of the longest in the world. Triggered as part of January's government crackdown against citizen protests nationwide, the regime implemented an internet shutdown that transcends the standard definition of internet censorship. This was not merely blocking social media or foreign websites; it was a total communications shutdown. Unlike previous Iranian internet shutdowns where Iran's domestic in

Phishing Attacks Against People Seeking Programming Jobs

This is new. North Korean hackers are posing as company recruiters, enticing job candidates to participate in coding challenges. When they run the code they are supposed to work on, it installs malware on their system. News article.

LLMs Generate Predictable Passwords

LLMs are bad at generating passwords: There are strong noticeable patterns among these 50 passwords that can be seen easily: All of the passwords start with a letter, usually uppercase G, almost always followed by the digit 7. Character choices are highly uneven ­ for example, L , 9, m, 2, $ and # appeared in all 50 passwords, but 5 and @ only appeared in one password each, and most of the letters in the alphabet never appeared at all. There are no repeating characters within any password. Proba

Poisoning AI Training Data

All it takes to poison AI training data is to create a website: I spent 20 minutes writing an article on my personal website titled "The best tech journalists at eating hot dogs." Every word is a lie. I claimed (without evidence) that competitive hot-dog-eating is a popular hobby among tech reporters and based my ranking on the 2026 South Dakota International Hot Dog Championship (which doesn't exist). I ranked myself number one, obviously. Then I listed a few fake reporters an

Is AI Good for Democracy?

Politicians fixate on the global race for technological supremacy between US and China. They debate geopolitical implications of chip exports, latest model releases from each country, and military applications of AI. Someday, they believe, we might see advancements in AI tip the scales in a superpower conflict. But the most important arms race of the 21st century is already happening elsewhere and, while AI is definitely the weapon of choice, combatants are distributed across dozens of domains.

On the Security of Password Managers

Good article on password managers that secretly have a backdoor. New research shows that these claims aren’t true in all cases, particularly when account recovery is in place or password managers are set to share vaults or organize users into groups. The researchers reverse-engineered or closely analyzed Bitwarden, Dashlane, and LastPass and identified ways that someone with control over the server­—either administrative or the result of a compromise­—can, in fact, steal data and, in

'Starkiller' Phishing Service Proxies Real Login Pages, MFA

Most phishing websites are little more than static copies of login pages for popular online destinations, and they are often quickly taken down by anti-abuse activists and security firms. But a stealthy new phishing-as-a-service offering lets customers sidestep both of these pitfalls: It uses cleverly disguised links to load the target brand's real website, and then acts as a relay between the target and the legitimate site -- forwarding the victim's username, password and multi-factor authentic

Ring Cancels Its Partnership with Flock

It's a demonstration of how toxic the surveillance-tech company Flock has become when Amazon's Ring cancels the partnership between the two companies. As Hamilton Nolan advises, remove your Ring doorbell.

Malicious AI

Interesting: Summary: An AI agent of unknown ownership autonomously wrote and published a personalized hit piece about me after I rejected its code, attempting to damage my reputation and shame me into accepting its changes into a mainstream python library. This represents a first-of-its-kind case study of misaligned AI behavior in the wild, and raises serious concerns about currently deployed AI agents executing blackmail threats. Part 2 of the story. And a Wall Street Journal article.

AI Found Twelve New Vulnerabilities in OpenSSL

The title of the post is"What AI Security Research Looks Like When It Works," and I agree: In the latest OpenSSL security release> on January 27, 2026, twelve new zero-day vulnerabilities (meaning unknown to the maintainers at time of disclosure) were announced. Our AI system is responsible for the original discovery of all twelve, each found and responsibly disclosed to the OpenSSL team during the fall and winter of 2025. Of those, 10 were assigned CVE-2025 identifiers and 2 rec

Side-Channel Attacks Against LLMs

Here are three papers describing different side-channel attacks against LLMs. "Remote Timing Attacks on Efficient Language Model Inference": Abstract: Scaling up language models has significantly increased their capabilities. But larger models are slower models, and so there is now an extensive body of work (e.g., speculative sampling or parallel decoding) that improves the (average case) efficiency of language model generation. But these techniques introduce data-dependent timing ch

The Promptware Kill Chain

Attacks against modern generative artificial intelligence (AI) large language models (LLMs) pose a real threat. Yet discussions around these attacks and their potential defenses are dangerously myopic. The dominant narrative focuses on "prompt injection," a set of techniques to embed instructions into inputs to LLM intended to perform malicious activity. This term suggests a simple, singular vulnerability. This framing obscures a more complex and dangerous reality. Attacks on LLM-bas

Bypassing Administrator Protection by Abusing UI Access

In my last blog post I introduced the new Windows feature, Administrator Protection and how it aimed to create a secure boundary for UAC where one didn’t exist. I described one of the ways I was able to bypass the feature before it was released. In total I found 9 bypasses during my research that have now all been fixed. In this blog post I wanted to describe the root cause of 5 of those 9 issues, specifically the implementation of UI Access, how this has been a long standing problem with UAC th

3D Printer Surveillance

New York is contemplating a bill that adds surveillance to 3D printers: New York’s 2026­2027 executive budget bill (S.9005 / A.10005) includes language that should alarm every maker, educator, and small manufacturer in the state. Buried in Part C is a provision requiring all 3D printers sold or delivered in New York to include "blocking technology." This is defined as software or firmware that scans every print file through a "firearms blueprint detection algorithm" and r

Kimwolf Botnet Swamps Anonymity Network I2P

For the past week, the massive "Internet of Things" (IoT) botnet known as Kimwolf has been disrupting the The Invisible Internet Project (I2P), a decentralized, encrypted communications network designed to anonymize and secure online communications. I2P users started reporting disruptions in the network around the same time the Kimwolf botmasters began relying on it to evade takedown attempts against the botnet's control servers.

I just noticed that the ebook version of Rewriring Democracy is on sale for $5 on Amazon, Apple Books, Barnes & Noble, Books A Million, Google Play, Kobo, and presumably everywhere else in the US. I have no idea how long this will last.

Prompt Injection Via Road Signs

Interesting research: "CHAI: Command Hijacking Against Embodied AI." Abstract: Embodied Artificial Intelligence (AI) promises to handle edge cases in robotic vehicle systems where data is scarce by using common-sense reasoning grounded in perception and action to generalize beyond training distributions and adapt to novel real-world situations. These capabilities, however, also create new security risks. In this paper, we introduce CHAI (Command Hijacking against embodied AI), a new

Microsoft today released updates to fix more than 50 security holes in its Windows operating systems and other software, including patches for a whopping six "zero-day" vulnerabilities that attackers are already exploiting in the wild.

AI-Generated Text and the Detection Arms Race

In 2023, the science fiction literary magazine Clarkesworld stopped accepting new submissions because so many were generated by artificial intelligence. Near as the editors could tell, many submitters pasted the magazine’s detailed story guidelines into an AI and sent in the results. And they weren’t alone. Other fiction magazines have also reported a high number of AI-generated submissions. This is only one example of a ubiquitous trend. A legacy system relied on the difficulty of writing and c
