Flok License Plate Surveillance
The company Flok is surveilling us as we drive:
A retired veteran named Lee Schmidt wanted to know how often Norfolk, Virginia’s 176 Flock Safety automated license-plate-reader cameras were tracking him. The answer, according to a U.S. District Court lawsuit filed in September, was more than four times a day, or 526 times from mid-February to early July. No, there’s no warrant out for Schmidt’s arrest, nor is there a warrant for Schmidt’s co-plaintiff, Crystal Arrington, whom the system tagged 849 times in roughly the same period.
You might think this sounds like it violates the Fourth Amendment, which protects American citizens from unreasonable searches and seizures without probable cause. Well, so does the American Civil Liberties Union. Norfolk, Virginia Judge Jamilah LeCruise also agrees, and in 2024 she ruled that plate-reader data obtained without a search warrant couldn’t be used against a defendant in a robbery case...

AI-Enabled Influence Operation Against Iran
Citizen Lab has uncovered a coordinated AI-enabled influence operation against the Iranian government, probably conducted by Israel.
Key Findings
- A coordinated network of more than 50 inauthentic X profiles is conducting an AI-enabled influence operation. The network, which we refer to as “PRISONBREAK,” is spreading narratives inciting Iranian audiences to revolt against the Islamic Republic of Iran.
- While the network was created in 2023, almost all of its activity was conducted starting in January 2025, and continues to the present day.
- The profiles’ activity appears to have been synchronized, at least in part, with the military campaign that the Israel Defense Forces conducted against Iranian targets in June 2025. ...

AI in the 2026 Midterm Elections
We are nearly one year out from the 2026 midterm elections, and it’s far too early to predict the outcomes. But it’s a safe bet that artificial intelligence technologies will once again be a major storyline.
The widespread fear that AI would be used to manipulate the 2024 U.S. election seems rather quaint in a year where the president posts AI-generated images of himself as the pope on official White House accounts. But AI is a lot more than an information manipulator. It’s also emerging as a politicized issue. Political first-movers are adopting the technology, and that’s opening a ...

Daniel Miessler on the AI Attack/Defense Balance
His conclusion:
Context wins
Basically whoever can see the most about the target, and can hold that picture in their mind the best, will be best at finding the vulnerabilities the fastest and taking advantage of them. Or, as the defender, applying patches or mitigations the fastest.
And if you’re on the inside you know what the applications do. You know what’s important and what isn’t. And you can use all that internal knowledge to fix things—hopefully before the baddies take advantage.
Summary and prediction
- Attackers will have the advantage for 3-5 years. For less-advanced defender teams, this will take much longer. ...

New report: “Scam GPT: GenAI and the Automation of Fraud.”
This primer maps what we currently know about generative AI’s role in scams, the communities most at risk, and the broader economic and cultural shifts that are making people more willing to take risks, more vulnerable to deception, and more likely to either perpetuate scams or fall victim to them.
AI-enhanced scams are not merely financial or technological crimes; they also exploit social vulnerabilities whether short-term, like travel, or structural, like precarious employment. This means they require social solutions in addition to technical ones. By examining how scammers are changing and accelerating their methods, we hope to show that defending against them will require a constellation of cultural shifts, corporate interventions, and effective legislation...

Digital Threat Modeling Under Authoritarianism
Today’s world requires us to make complex and nuanced decisions about our digital security. Evaluating when to use a secure messaging app like Signal or WhatsApp, which passwords to store on your smartphone, or what to share on social media requires us to assess risks and make judgments accordingly. Arriving at any conclusion is an exercise in threat modeling.
In security, threat modeling is the process of determining what security measures make sense in your particular situation. It’s a way to think about potential risks, possible defenses, and the costs of both. It’s how experts avoid being distracted by irrelevant risks or overburdened by undue costs...

Apple’s New Memory Integrity Enforcement
Apple has introduced a new hardware/software security feature in the iPhone 17: “Memory Integrity Enforcement,” targeting the memory safety vulnerabilities that spyware products like Pegasus tend to use to get unauthorized system access. From Wired:
In recent years, a movement has been steadily growing across the global tech industry to address a ubiquitous and insidious type of bugs known as memory-safety vulnerabilities. A computer’s memory is a shared resource among all programs, and memory safety issues crop up when software can pull data that should be off limits from a computer’s memory or manipulate data in memory that shouldn’t be accessible to the program. When developers—even experienced and security-conscious developers—write software in ubiquitous, historic programming languages, like C and C++, it’s easy to make mistakes that lead to memory safety vulnerabilities. That’s why proactive tools like ...

Surveying the Global Spyware Market
The Atlantic Council has published its second annual report: “Mythical Beasts: Diving into the depths of the global spyware market.”
Too much good detail to summarize, but here are two items:
First, the authors found that the number of US-based investors in spyware has notably increased in the past year, when compared with the sample size of the spyware market captured in the first Mythical Beasts project. In the first edition, the United States was the second-largest investor in the spyware market, following Israel. In that edition, twelve investors were observed to be domiciled within the United States—whereas in this second edition, twenty new US-based investors were observed investing in the spyware industry in 2024. This indicates a significant increase of US-based investments in spyware in 2024, catapulting the United States to being the largest investor in this sample of the spyware market. This is significant in scale, as US-based investment from 2023 to 2024 largely outpaced that of other major investing countries observed in the first dataset, including Italy, Israel, and the United Kingdom. It is also significant in the disparity it points to the visible enforcement gap between the flow of US dollars and US policy initiatives. Despite numerous US policy actions, such as the addition of spyware vendors on the ...

Time-of-Check Time-of-Use Attacks Against LLMs
This is a nice piece of research: “Mind the Gap: Time-of-Check to Time-of-Use Vulnerabilities in LLM-Enabled Agents“.:
Abstract: Large Language Model (LLM)-enabled agents are rapidly emerging across a wide range of applications, but their deployment introduces vulnerabilities with security implications. While prior work has examined prompt-based attacks (e.g., prompt injection) and data-oriented threats (e.g., data exfiltration), time-of-check to time-of-use (TOCTOU) remain largely unexplored in this context. TOCTOU arises when an agent validates external state (e.g., a file or API response) that is later modified before use, enabling practical attacks such as malicious configuration swaps or payload injection. In this work, we present the first study of TOCTOU vulnerabilities in LLM-enabled agents. We introduce TOCTOU-Bench, a benchmark with 66 realistic user tasks designed to evaluate this class of vulnerabilities. As countermeasures, we adapt detection and mitigation techniques from systems security to this setting and propose prompt rewriting, state integrity monitoring, and tool-fusing. Our study highlights challenges unique to agentic workflows, where we achieve up to 25% detection accuracy using automated detection methods, a 3% decrease in vulnerable plan generation, and a 95% reduction in the attack window. When combining all three approaches, we reduce the TOCTOU vulnerabilities from an executed trajectory from 12% to 8%. Our findings open a new research direction at the intersection of AI safety and systems security...

Nondestructive detection of multiple dried squid qualities by hyperspectral imaging combined with 1D-KAN-CNN
Abstract: Given that dried squid is a highly regarded marine product in Oriental countries, the global food industry requires a swift and noninvasive quality assessment of this product. The current study therefore uses visiblenear-infrared (VIS-NIR) hyperspectral imaging and deep learning (DL) methodologies. We acquired and preprocessed VIS-NIR (4001000 nm) hyperspectral reflectance images of 93 dried squid samples. Important wavelengths were selected using competitive adaptive reweighted sampling, principal component analysis, and the successive projections algorithm. Based on a Kolmogorov-Arnold network (KAN), we introduce a one-dimensional, KAN convolutional neural network (1D-KAN-CNN) for nondestructive measurements of fat, protein, and total volatile basic nitrogen…...

Interesting analysis:
When cyber incidents occur, victims should be notified in a timely manner so they have the opportunity to assess and remediate any harm. However, providing notifications has proven a challenge across industry.

Victims often do not trust these notifications, as cyber criminals often use the pretext of an account compromise as a phishing lure.

This is a pretty exciting paper from a theoretical perspective, but I don’t see it leading to any practical real-world cryptanalysis.

Editor’s summary:
Cephalopods are one of the most successful marine invertebrates in modern oceans, and they have a 500-million-year-old history. However, we know very little about their evolution because soft-bodied animals rarely fossilize. Ikegami et al. developed an approach to reveal squid fossils, focusing on their beaks, the sole hard component of their bodies. They found that squids radiated rapidly after shedding their shells, reaching high levels of diversity by 100 million years ago. This finding shows both that squid body forms led to early success and that their radiation was not due to the end-Cretaceous extinction event...

Generative AI as a Cybercrime Assistant
Anthropic reports on a Claude user:
We recently disrupted a sophisticated cybercriminal that used Claude Code to commit large-scale theft and extortion of personal data. The actor targeted at least 17 distinct organizations, including in healthcare, the emergency services, and government and religious institutions. Rather than encrypt the stolen information with traditional ransomware, the actor threatened to expose the data publicly in order to attempt to extort victims into paying ransoms that sometimes exceeded $500,000.
The actor used AI to what we believe is an unprecedented degree. Claude Code was used to automate reconnaissance, harvesting victims’ credentials, and penetrating networks. Claude was allowed to make both tactical and strategic decisions, such as deciding which data to exfiltrate, and how to craft psychologically targeted extortion demands. Claude analyzed the exfiltrated financial data to determine appropriate ransom amounts, and generated visually alarming ransom notes that were displayed on victim machines...

Indirect Prompt Injection Attacks Against LLM Assistants
Really good research on practical attacks against LLM agents.
Abstract: The growing integration of LLMs into applications has introduced new security risks, notably known as Promptware—maliciously engineered prompts designed to manipulate LLMs to compromise the CIA triad of these applications. While prior research warned about a potential shift in the threat landscape for LLM-powered applications, the risk posed by Promptware is frequently perceived as low. In this paper, we investigate the risk Promptware poses to users of Gemini-powered assistants (web application, mobile application, and Google Assistant). We propose a novel Threat Analysis and Risk Assessment (TARA) framework to assess Promptware risks for end users. Our analysis focuses on a new variant of Promptware called Targeted Promptware Attacks, which leverage indirect prompt injection via common user interactions such as emails, calendar invitations, and shared documents. We demonstrate 14 attack scenarios applied against Gemini-powered assistants across five identified threat classes: Short-term Context Poisoning, Permanent Memory Poisoning, Tool Misuse, Automatic Agent Invocation, and Automatic App Invocation. These attacks highlight both digital and physical consequences, including spamming, phishing, disinformation campaigns, data exfiltration, unapproved user video streaming, and control of home automation devices. We reveal Promptware’s potential for on-device lateral movement, escaping the boundaries of the LLM-powered application, to trigger malicious actions using a device’s applications. Our TARA reveals that 73% of the analyzed threats pose High-Critical risk to end users. We discuss mitigations and reassess the risk (in response to deployed mitigations) and show that the risk could be reduced significantly to Very Low-Medium. We disclosed our findings to Google, which deployed dedicated mitigations...

Here’s an interesting story about a failure being introduced by LLM-written code. Specifically, the LLM was doing some code refactoring, and when it moved a chunk of code from one file to another it changed a “break” to a “continue.” That turned an error logging statement into an infinite loop, which crashed the system.
This is an integrity failure. Specifically, it’s a failure of processing integrity. And while we can think of particular patches that alleviate this exact failure, the larger problem is much harder to solve.

A few years ago, scammers invented a new phishing email. They would claim to have hacked your computer, turned your webcam on, and videoed you watching porn or having sex. BuzzFeed has an article talking about a “shockingly realistic” variant, which includes photos of you and your house—more specific information.
The article contains “steps you can take to figure out if it’s a scam,” but omits the first and most fundamental piece of advice: If the hacker had incriminating video about you, they would show you a clip. Just a taste, not the worst bits so you had to worry about how bad it could be, but something. If the hacker doesn’t show you any video, they don’t have any video.

Spying on People Through Airportr Luggage Delivery Service
Airportr is a service that allows passengers to have their luggage picked up, checked, and delivered to their destinations. As you might expect, it’s used by wealthy or important people. So if the company’s website is insecure, you’d be able to spy on lots of wealthy or important people. And maybe even steal their luggage.
Researchers at the firm CyberX9 found that simple bugs in Airportr’s website allowed them to access virtually all of those users’ personal information, including travel plans, or even gain administrator privileges that would have allowed a hacker to redirect or steal luggage in transit. Among even the small sample of user data that the researchers reviewed and shared with WIRED they found what appear to be the personal information and travel records of multiple government officials and diplomats from the UK, Switzerland, and the US...

Cheating on Quantum Computing Benchmarks
Peter Gutmann and Stephan Neuhaus have a new paper—I think it’s new, even though it has a March 2025 date—that makes the argument that we shouldn’t trust any of the quantum factorization benchmarks, because everyone has been cooking the books:
Similarly, quantum factorisation is performed using sleight-of-hand numbers that have been selected to make them very easy to factorise using a physics experiment and, by extension, a VIC-20, an abacus, and a dog. A standard technique is to ensure that the factors differ by only a few bits that can then be found using a simple search-based approach that has nothing to do with factorisation…. Note that such a value would never be encountered in the real world since the RSA key generation process typically requires that |p-q| > 100 or more bits [9]. As one analysis puts it, “Instead of waiting for the hardware to improve by yet further orders of magnitude, researchers began inventing better and better tricks for factoring numbers by exploiting their hidden structure” [10]...

“Encryption Backdoors and the Fourth Amendment”
Law journal article that looks at the Dual_EC_PRNG backdoor from a US constitutional perspective:
Abstract: The National Security Agency (NSA) reportedly paid and pressured technology companies to trick their customers into using vulnerable encryption products. This Article examines whether any of three theories removed the Fourth Amendment’s requirement that this be reasonable. The first is that a challenge to the encryption backdoor might fail for want of a search or seizure. The Article rejects this both because the Amendment reaches some vulnerabilities apart from the searches and seizures they enable and because the creation of this vulnerability was itself a search or seizure. The second is that the role of the technology companies might have brought this backdoor within the private-search doctrine. The Article criticizes the doctrine particularly its origins in Burdeau v. McDowelland argues that if it ever should apply, it should not here. The last is that the customers might have waived their Fourth Amendment rights under the third-party doctrine. The Article rejects this both because the customers were not on notice of the backdoor and because historical understandings of the Amendment would not have tolerated it. The Article concludes that none of these theories removed the Amendment’s reasonableness requirement...

Seems like an old system system that predates any care about security:
The flaw has to do with the protocol used in a train system known as the End-of-Train and Head-of-Train. A Flashing Rear End Device (FRED), also known as an End-of-Train (EOT) device, is attached to the back of a train and sends data via radio signals to a corresponding device in the locomotive called the Head-of-Train (HOT). Commands can also be sent to the FRED to apply the brakes at the rear of the train.
These devices were first installed in the 1980s as a replacement for caboose cars, and unfortunately, they lack encryption and authentication protocols. Instead, the current system uses data packets sent between the front and back of a train that include a simple BCH checksum to detect errors or interference. But now, the CISA is warning that someone using a software-defined radio could potentially send fake data packets and interfere with train operations...

Undeterred, the team instead focused on finding ancient squid beaks—hard mouthparts with high fossilization potential that could help the team figure out how squids evolved.
With that in mind, the team developed an advanced fossil discovery technique that completely digitized rocks with all their embedded fossils in complete 3D form.

A whole class of speculative execution attacks against CPUs were published in 2018. They seemed pretty catastrophic at the time. But the fixes were as well. Speculative execution was a way to speed up CPUs, and removing those enhancements resulted in significant performance drops.
Now, people are rethinking the trade-off. Ubuntu has disabled some protections, resulting in 20% performance boost.
After discussion between Intel and Canonical’s security teams, we are in agreement that Spectre no longer needs to be mitigated for the GPU at the Compute Runtime level. At this point, Spectre has been mitigated in the kernel, and a clear warning from the Compute Runtime build serves as a notification for those running modified kernels without those patches. For these reasons, we feel that Spectre mitigations in Compute Runtime no longer offer enough security impact to justify the current performance tradeoff...
