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 special programming languages have been proliferating with the goal of making it structurally impossible for software to contain these vulnerabilities, rather than attempting to avoid introducing them or catch all of them.

[…]

With memory-unsafe programming languages underlying so much of the world’s collective code base, Apple’s Security Engineering and Architecture team felt that putting memory safety mechanisms at the heart of Apple’s chips could be a deus ex machina for a seemingly intractable problem. The group built on a specification known as Memory Tagging Extension (MTE) released in 2019 by the chipmaker Arm. The idea was to essentially password protect every memory allocation in hardware so that future requests to access that region of memory are only granted by the system if the request includes the right secret.

Arm developed MTE as a tool to help developers find and fix memory corruption bugs. If the system receives a memory access request without passing the secret check, the app will crash and the system will log the sequence of events for developers to review. Apple’s engineers wondered whether MTE could run all the time rather than just being used as a debugging tool, and the group worked with Arm to release a version of the specification for this purpose in 2022 called Enhanced Memory Tagging Extension.

To make all of this a constant, real-time defense against exploitation of memory safety vulnerabilities, Apple spent years architecting the protection deeply within its chips so the feature could be on all the time for users without sacrificing overall processor and memory performance. In other words, you can see how generating and attaching secrets to every memory allocation and then demanding that programs manage and produce these secrets for every memory request could dent performance. But Apple says that it has been able to thread the needle.

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.

[…]

It is tempting to think of the Great Firewall or Chinese propaganda as the outcome of a top-down master plan that only the Chinese Communist Party could pull off. But these leaks suggest a more complicated reality. Censorship and propaganda efforts must be marketed, financed, and maintained. They are shaped by the logic of corporate quarterly financial targets and competitive bids as much as by ideology­—except the customers are governments, and the products can control or shape entire societies.

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 Entity List, and the broader global leadership role that the United States has played through imposing sanctions and diplomatic engagement, US investments continue to fund the very entities that US policymakers are making an effort to combat.

Second, the authors elaborated on the central role that resellers and brokers play in the spyware market, while being a notably under-researched set of actors. These entities act as intermediaries, obscuring the connections between vendors, suppliers, and buyers. Oftentimes, intermediaries connect vendors to new regional markets. Their presence in the dataset is almost assuredly underrepresented given the opaque nature of brokers and resellers, making corporate structures and jurisdictional arbitrage more complex and challenging to disentangle. While their uptick in the second edition of the Mythical Beasts project may be the result of a wider, more extensive data-collection effort, there is less reporting on resellers and brokers, and these entities are not systematically understood. As observed in the first report, the activities of these suppliers and brokers represent a critical information gap for advocates of a more effective policy rooted in national security and human rights. These discoveries help bring into sharper focus the state of the spyware market and the wider cyber-proliferation space, and reaffirm the need to research and surface these actors that otherwise undermine the transparency and accountability efforts by state and non-state actors as they relate to the spyware market.

Really good work. Read the whole thing.

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.

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.”

[…]

Omo and Rowley say they informed Securam about both their safe-opening techniques in spring of last year, but have until now kept their existence secret because of legal threats from the company. “We will refer this matter to our counsel for trade libel if you choose the route of public announcement or disclosure,” a Securam representative wrote to the two researchers ahead of last year’s Defcon, where they first planned to present their research.

Only after obtaining pro bono legal representation from the Electronic Frontier Foundation’s Coders’ Rights Project did the pair decide to follow through with their plan to speak about Securam’s vulnerabilities at Defcon. Omo and Rowley say they’re even now being careful not to disclose enough technical detail to help others replicate their techniques, while still trying to offer a warning to safe owners about two different vulnerabilities that exist in many of their devices.

The company says that it plans on updating its locks by the end of the year, but have no plans to patch any locks already sold.
