AI in the 2026 Midterm Elections

9 hours 10 min ago

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

Thu, 10/02/2025 - 12:19pm

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

  1. Attackers will have the advantage for 3-5 years. For less-advanced defender teams, this will take much longer. ...

Use of Generative AI in Scams

Wed, 10/01/2025 - 7:09am

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...

Details of a Scam

Longtime Crypto-Gram readers know that I collect personal experiences of people being scammed. Here’s an almost:

Then he added, “Here at Chase, we’ll never ask for your personal information or passwords.” On the contrary, he gave me more information—two “cancellation codes” and a long case number with four letters and 10 digits.

That’s when he offered to transfer me to his supervisor. That simple phrase, familiar from countless customer-service calls, draped a cloak of corporate competence over this unfolding drama. His supervisor. I mean, would a scammer have a supervisor?...

Abusing Notion’s AI Agent for Data Theft

Mon, 09/29/2025 - 7:07am

Notion just released version 3.0, complete with AI agents. Because the system contains Simon Willson’s lethal trifecta, it’s vulnerable to data theft though prompt injection.

First, the trifecta:

The lethal trifecta of capabilities is:

  • Access to your private data—one of the most common purposes of tools in the first place!
  • Exposure to untrusted content—any mechanism by which text (or images) controlled by a malicious attacker could become available to your LLM
  • The ability to externally communicate in a way that could be used to steal your data (I often call this “exfiltration” but I’m not confident that term is widely understood.)...

Digital Threat Modeling Under Authoritarianism

Fri, 09/26/2025 - 7:04am

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...

US Disrupts Massive Cell Phone Array in New York

Wed, 09/24/2025 - 7:09am

This is a weird story:

The US Secret Service disrupted a network of telecommunications devices that could have shut down cellular systems as leaders gather for the United Nations General Assembly in New York City.

The agency said on Tuesday that last month it found more than 300 SIM servers and 100,000 SIM cards that could have been used for telecom attacks within the area encompassing parts of New York, New Jersey and Connecticut.

“This network had the power to disable cell phone towers and essentially shut down the cellular network in New York City,” said special agent in charge Matt McCool...

Apple’s New Memory Integrity Enforcement

Tue, 09/23/2025 - 7:07am

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 ...

Details About Chinese Surveillance and Propaganda Companies

Mon, 09/22/2025 - 7:03am

Details from leaked documents:

While people often look at China’s Great Firewall as a single, all-powerful government system unique to China, the actual process of developing and maintaining it works the same way as surveillance technology in the West. Geedge collaborates with academic institutions on research and development, adapts its business strategy to fit different clients’ needs, and even repurposes leftover infrastructure from its competitors.

[…]

The parallels with the West are hard to miss. A number of American surveillance and propaganda firms also started as academic projects before they were spun out into startups and grew by chasing government contracts. The difference is that in China, these companies operate with far less transparency. Their work comes to light only when a trove of documents slips onto the internet...

Surveying the Global Spyware Market

Fri, 09/19/2025 - 7:01am

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

Thu, 09/18/2025 - 7:06am

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...

Hacking Electronic Safes

Vulnerabilities in electronic safes that use Securam Prologic locks:

While both their techniques represent glaring security vulnerabilities, Omo says it’s the one that exploits a feature intended as a legitimate unlock method for locksmiths that’s the more widespread and dangerous. “This attack is something where, if you had a safe with this kind of lock, I could literally pull up the code right now with no specialized hardware, nothing,” Omo says. “All of a sudden, based on our testing, it seems like people can get into almost any Securam Prologic lock in the world.”...

Microsoft Still Uses RC4

Lawsuit About WhatsApp Security

Mon, 09/15/2025 - 7:05am

Attaullah Baig, WhatsApp’s former head of security, has filed a whistleblower lawsuit alleging that Facebook deliberately failed to fix a bunch of security flaws, in violation of its 2019 settlement agreement with the Federal Trade Commission.

The lawsuit, alleging violations of the whistleblower protection provision of the Sarbanes-Oxley Act passed in 2002, said that in 2022, roughly 100,000 WhatsApp users had their accounts hacked every day. By last year, the complaint alleged, as many as 400,000 WhatsApp users were getting locked out of their accounts each day as a result of such account takeovers...

Assessing the Quality of Dried Squid

Fri, 09/12/2025 - 5:05pm

Research:

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…...
