Summary: Design Patterns for Securing LLM Agents against Prompt Injections

A new paper, authored by 11 researchers from major organizations like IBM and Google, discusses strategies to protect LLM agents from prompt injection attacks. The authors propose design patterns that limit agent capabilities to enhance security while still allowing useful functions.

Key Points:

1. Understanding the Problem: The authors recognize that general-purpose agents currently lack reliable safety guarantees against prompt injections. Their focus is on creating agents that can perform useful tasks while minimizing risks.

2. Design Patterns: They introduce six design patterns to mitigate prompt injection risks:

   • Action-Selector Pattern: Agents can initiate actions without access to the results, preventing harmful responses.
   • Plan-Then-Execute Pattern: Agents plan actions before receiving untrusted input, ensuring that malicious content doesn’t affect decisions.
   • LLM Map-Reduce Pattern: Sub-agents process untrusted content separately, and results are aggregated safely.
   • Dual LLM Pattern: A privileged LLM manages a quarantined LLM to avoid exposure to untrusted data.
   • Code-Then-Execute Pattern: The privileged LLM writes code in a controlled environment to specify tool usage and manage data flow.
   • Context-Minimization Pattern: The agent removes unnecessary user prompts from context to prevent potential injections.

3. Case Studies: The paper includes ten practical case studies demonstrating how these patterns can be applied, such as in customer service, medical diagnosis, and software engineering contexts.

4. Final Thoughts: The author expresses optimism about the increasing attention to prompt injection problems in research, emphasizing the importance of developing secure agent systems.

In summary, this paper contributes valuable insights and practical solutions to the ongoing challenge of securing LLM agents against prompt injections.

This work demonstrates that the geometry of Euclidean 3-space can arise from the way quantum measurements are related over time when measuring a single qubit's properties (called Pauli observables). Interestingly, these quantum correlations do not depend on the qubit’s initial state. This means that an observer can gather geometric information from these measurements without needing to know the starting conditions of the qubit. The findings imply that space might originate from these quantum correlations, and the authors propose a simple model to explore this idea further.

In late 2024, researchers uncovered that Kremlin-backed disinformation campaigns were using advanced advertising technology to evade moderation on social media. This technology, known as "dark ad tech," helps spread fake news, particularly through a network called "Doppelganger," which promotes pro-Russian narratives via cloned websites.

Doppelganger utilizes a technique called “domain cloaking” to show different content to search engines and users, keeping the disinformation online longer. It shares infrastructure with VexTrio, a malicious traffic distribution system (TDS) that typically manages traffic from phishing and malware victims.

One notable aspect of this investigation is the LosPollos ad network, which uses themes from the show "Breaking Bad" and employs tactics to drive traffic to dubious dating sites and scams. Affiliates earn commissions by embedding deceptive links on hacked websites. Another related network, TacoLoco, tricks users into enabling push notifications that bombard them with misleading alerts.

The research revealed connections between these networks and a company called Adspro Group, which operates using Swiss hosting services. Despite denials from Adspro's CEO regarding links to VexTrio, evidence suggests they share similar practices and infrastructure.

As of early 2025, other malware strains have shifted their traffic away from VexTrio to another TDS called Help TDS, indicating ongoing adaptations in malicious advertising strategies. Security experts emphasize that the threats posed by these ad tech systems are serious, as they can lead to significant financial scams.

To protect against these issues, users are advised to be cautious with push notifications and consider blocking them in their browser settings.

Summary of the June 12, 2025 Newsletter:

The newsletter discusses using SMT (Satisfiability Modulo Theories) solvers to tackle a puzzle called "LinkedIn Queens," which is a variation of the classic N-Queens problem. The author highlights that solving this problem with SMT is easier than using traditional SAT (Boolean SATisfiability) solvers, which are often underutilized in the industry.

Key points include:

• LinkedIn Queens Puzzle: You must place N queens on an NxN grid, ensuring no two queens are in the same row, column, or region, while allowing for diagonal placements.
• SMT vs. SAT: SMT solvers can handle a broader range of data types and can simplify the problem-solving process compared to SAT solvers, which deal only with boolean variables.
• Implementation: The author provides a brief overview of how to set up the SMT solver using the Z3 library in Python. This includes defining constraints for queen positions and regions and checking for valid solutions.
• Sanity Checks: The author emphasizes the importance of adding checks to ensure the regions are set up correctly, as mistakes in encoding can occur.

The newsletter also mentions that there will be no issue next week due to the author's upcoming talk at a conference.

In 2001, a significant fossil skull known as Toumaï was discovered in the Djurab desert of Chad, believed to be the oldest known ancestor of humans, dating back 6 to 7 million years. Palaeontologist Michel Brunet announced the find, naming it Sahelanthropus tchadensis, which suggested human evolution might have originated in the Sahara rather than East Africa.

However, the discovery sparked intense debate among scientists regarding whether Toumaï was truly a hominin. Critics argued that the skull did not provide enough evidence of bipedalism, a key trait for identifying ancient human ancestors. The situation escalated when it was revealed that a femur, potentially belonging to Toumaï, had been discovered alongside the skull but was initially overlooked.

Brunet became a prominent figure in the scientific community, but his relationships with colleagues soured, particularly with Roberto Macchiarelli, who examined the femur without Brunet's permission. Tensions over the femur led to accusations of scientific misconduct and ethical breaches, culminating in a long-standing feud between Brunet’s supporters and Macchiarelli’s camp.

Despite the controversies, further studies eventually concluded that Sahelanthropus was likely bipedal, reinforcing its significance in human evolution. The ongoing debates highlight the complexities and competitive nature of palaeoanthropology, where new fossil discoveries can dramatically alter our understanding of human ancestry. The narrative of Toumaï serves as a reminder of the challenges and rivalries inherent in scientific research, especially in the quest to uncover our origins.

A recent study from Aarhus University and the University of Oxford reveals that when we listen to sounds, our brains don’t just respond; they actually reorganize themselves in real time. This finding comes from a new imaging technique called FREQ-NESS, which tracks how different sound frequencies move through brain networks.

The research shows that sounds trigger complex changes in brainwave patterns, suggesting that our brain is more dynamic than previously thought. Instead of being static, brain activity shifts according to the frequencies of sounds we hear, which can change our perception and attention.

This method, FREQ-NESS, allows scientists to map brain activity with high precision, offering new insights into music cognition, consciousness, and brain-computer interfaces. The study opens up possibilities for personalized brain mapping and could influence how we study brain responses to various stimuli.

Overall, the research highlights that our brains continuously adapt to auditory experiences, reshaping their networks in the process.

OpenAI has significantly reduced the pricing for its o3 model by 80% and launched a new version called o3-pro. This new model shows improved performance, achieving a 64% win rate over the previous version in human tests. The author, Ben Hylak, shares his early experiences with o3-pro, emphasizing the importance of providing context when using it.

He notes that while o3-pro is much smarter, it requires more context to demonstrate its capabilities. In his tests, when he provided detailed background information, o3-pro generated highly effective plans that changed their approach to future projects.

Hylak points out that AI models excel in isolation but need better integration into real-world applications. o3-pro shows improvements in collaborating with humans and using tools effectively. However, it can overthink if not given enough context, and he finds it better at orchestrating tasks rather than performing them directly.

Overall, he concludes that successful use of reasoning models still relies heavily on context and well-crafted prompts. The advancements in o3-pro indicate a shift towards models that can reason about tool usage effectively.

The article discusses whether Python dictionaries are ordered data structures. Here are the key points:

1. Historical Context: Before Python 3.6, dictionaries did not maintain any order. In versions 3.6 and later, dictionaries preserve the order of insertion, meaning the order in which items are added is the order they will be displayed.

2. Python Versions: From Python 3.6, this order preservation was an implementation detail, and in Python 3.7, it became part of the official language specification. Therefore, from 3.7 onward, you can rely on dictionaries keeping the order in which you insert items.

3. Equality of Dictionaries: Even though dictionaries maintain insertion order, two dictionaries with the same key-value pairs but different orders are considered equal. This is different from sequences like lists, where order matters.

4. OrderedDict: Python also has an OrderedDict type, which explicitly maintains order. Unlike standard dictionaries, two OrderedDict instances with the same items in a different order are not considered equal.

5. Conclusion: While dictionaries preserve order, this feature is not a defining characteristic like it is for sequences. The main purpose of a dictionary is to map keys to values, and order is secondary.

Overall, dictionaries are not classified as ordered data structures in the same way as lists and other sequences, but they do maintain the order of insertion starting from Python 3.6.

The authors introduce a new type of electromagnetic (EM) attack that allows attackers to eavesdrop on conversations using digital microphones found in devices like laptops and smart speakers. This attack focuses on microphones that convert sound into digital signals through pulse-density modulation (PDM). The researchers found that the digital pulses still carry audio information, which can be retrieved using standard radio receivers.

In tests, they demonstrated the attack could accurately recognize spoken digits from up to 2 meters away, even through a concrete wall. They also showed that popular speech-to-text software could transcribe this captured audio with relatively low error rates. Notably, the attack works with inexpensive equipment, like a homemade antenna.

The authors discuss the weaknesses of current defenses against such attacks and suggest a new hardware solution involving clock randomization. Overall, this research highlights significant vulnerabilities in modern electronic devices regarding audio privacy.

The author created a project called Eyesite as a DIY alternative to the Apple Vision Pro, which costs $3,500. Eyesite allows users to interact with a website using their eyes instead of a mouse, utilizing a Javascript library called WebGazer.js for eye tracking.

To set up eye tracking, users must calibrate their gaze by looking at specific points on the screen multiple times. The project aims to make the experience smooth and immersive. Initially, a red dot indicated where users were looking, but this was distracting and revealed inaccuracies in tracking. The author removed the visible cursor to enhance the feeling of control.

To help users recognize interactive buttons, the interface responds with a glow when the user's gaze hovers over them. Since eye tracking isn't perfect, the user interface (UI) is designed to be large, which accommodates any tracking jitters.

The author encourages others to explore or improve upon the Eyesite project, which is available on GitHub.

Two European journalists were hacked using spyware from Israeli company Paragon, according to a report by The Citizen Lab. The affected journalists include Italian journalist Ciro Pellegrino and another unnamed European journalist. Evidence suggests they were both hacked by the same Paragon customer, likely linked to the Italian government.

Pellegrino, who works for the news site Fanpage, had previously received a notification from Apple about a spyware attack but was not initially informed that it involved Paragon. Recent findings indicate that this incident is part of a larger spyware scandal involving Italian authorities, which may also affect other European countries.

The Citizen Lab's investigation revealed that both journalists were targeted using a sophisticated "zero-click" attack through iMessage, meaning they did not need to interact with any suspicious links for their devices to be compromised. The report raises questions about the Italian government's involvement in spying on journalists, with Pellegrino expressing concerns over his civil rights.

In addition to Pellegrino, two other Italian activists were confirmed to have been targeted by the same spyware. The investigation is ongoing, and further analyses may reveal more about the extent of the spyware's use against journalists and activists in Italy and beyond.

In South Korea, age plays a significant role in social interactions, which can be surprising for newcomers. Unlike in Germany, where age isn't a big deal, Koreans often ask about your birth year early in conversations. This is important because friendships are often defined by age; the term "친구 / chingu" (friend) is used only for those born in the same year.

Korean culture emphasizes respect for elders, creating a strict age hierarchy. The language reflects this with different speech levels that show varying degrees of respect based on age. Younger people must speak formally to older individuals and typically use titles instead of names when addressing them.

Koreans use two age systems: international age and Korean age. In Korean age, you are considered one year old at birth and gain an additional year on January 1st, making your Korean age usually one or two years older than your international age. This can lead to confusion, so people often ask for your birth year instead.

Recently, South Korea has started using the international age more, officially adopting it in June 2023, but Korean age is still commonly used, especially for legal matters like the drinking age, which is 20 in Korean age.

Summary: The Fiefdom of Files - Lessons from an 1834 Landscape Gardening Guidebook

Hermann Ludwig Heinrich, Count of Pückler-Muskau, born in 1785, is known today not for his political status but for Pückler Ice Cream, a dessert named after him. He was passionate about landscape gardening and wrote "Hints on Landscape Gardening" to improve the design of parks in Prussia.

Pückler's guide covers everything from basic tree planting to advanced techniques for keeping commoners from damaging gardens. His insights can apply to various design projects, such as software development or game design.

Key lessons from his work include:

1. Show the Obstacle: Curved paths in parks should have reasons for their design. This makes walking more enjoyable. For example, instead of letting visitors see everything at once, hide certain views to build anticipation.

2. Hide the Castle: Important sights should not be immediately visible. This creates excitement and makes the reveal more rewarding.

3. Emulate, Don’t Simulate: Parks should mimic nature while being artificial. Designs should reflect natural patterns, such as the way trees and rivers appear in nature, rather than just placing elements randomly.

Pückler's principles encourage thoughtful and engaging design in both physical and digital environments, aiming to create spaces that are enjoyable and meaningful.

Archaeologists may have finally solved the mystery of the Roanoke Colony, America's first English settlement that vanished in the late 16th century. Research led by Mark Horton from the Royal Agricultural University suggests that the settlers, who disappeared around 1590, did not meet a tragic fate but instead assimilated into the local Croatoan Native American community.

The team discovered tiny iron fragments known as hammerscale in trash heaps on Hatteras Island, which indicate iron-working technology that Native Americans at the time did not possess. This evidence suggests that the English colonists lived among the Croatoans after leaving Roanoke Island.

Additionally, other artifacts found include guns, nautical fittings, and various personal items, further supporting the idea that the colonists adapted to their new environment rather than facing death or conflict. The findings suggest the colonists may have survived and integrated into the local population, with descendants living in the area for years afterward. Although the archaeological evidence is strong, Horton notes that the legend of the Lost Colony will likely continue to captivate people's imaginations.

Summary of "Inbox Zero for Error Tracking"

The concept of Inbox Zero suggests that your email inbox should not be a cluttered space but rather a place where every message is either dealt with, archived, or deleted. This principle can also be applied to error tracking in software development.

Key Points:

1. Treat Errors Like Emails: Just as you manage emails, you should manage errors. Each error should be addressed—either fixed, investigated, or ignored if irrelevant. The aim is to have zero unresolved errors.

2. Regular Check-Ins: You don’t need to check errors constantly but should set a regular schedule (daily or weekly) to review and clear them. This helps reduce mental clutter and anxiety over unresolved issues.

3. No Need for Dashboards: You don’t need complex tools or metrics to act on errors. Each incoming error should be reviewed individually to determine its relevance, rather than relying on frequency or volume.

4. Catch Errors Early: Addressing errors promptly prevents them from causing further issues down the line, much like how you handle failing tests in a continuous integration (CI) pipeline.

5. Clarity and Focus: A clean error tracker allows you to focus on the most important issues without being overwhelmed by a backlog of unresolved errors. It enhances productivity and decision-making.

6. Limitations of Inbox Zero: This approach doesn’t work for every situation. In noisy environments or for minor issues, trying to achieve Inbox Zero can be counterproductive.

7. Personal Approach: The author uses a case-by-case method for managing errors, being more diligent with critical applications while allowing some leniency in local development.

8. Tool Support: Not all error tracking tools are designed for Inbox Zero. It’s essential to have user-friendly tools that facilitate quick resolutions and support the goal of keeping errors to a minimum.

Conclusion: Implementing Inbox Zero for error tracking can lead to greater peace of mind and efficiency, allowing developers to focus better and make quicker decisions. While it's not suitable for every project, it can be very effective when applied appropriately.

Samuel Pepys' diary was first published in June 1825 and quickly became popular, with newspapers sharing quotes from it. Notable entries include his accounts of the Great Fire of London and personal moments like trying tea for the first time. By the late 19th century, the diary was recognized as a classic in British history and literature. Today, Pepys is featured in museum exhibits and historical novels, and his writings are often used to teach students about the Restoration period in England.

Summary of AlphaWrite: Inference Time Compute Scaling for Writing

AlphaWrite is a new framework designed to enhance creative text generation using advanced computational techniques. While large language models (LLMs) have improved in areas like math and coding, creative writing has not seen similar advancements due to the subjective nature of evaluating narratives.

Key Points:

1. Evolutionary Approach: AlphaWrite employs an evolutionary model for iterative story generation. It combines story creation with a ranking system inspired by Elo ratings, allowing stories to compete and evolve over generations.

2. Methodology:

   • Initial Generation: A diverse set of stories is created using various author styles and themes.
   • Judging and Ranking: Stories are compared in pairs, and an LLM judge scores them based on narrative quality, updating their Elo rankings.
   • Evolution: The top stories are selected to generate new variants, which keeps the creative output diverse and progressively improves story quality.

3. Evaluation Challenges: Assessing story quality is complex due to subjective preferences. The study focuses on short stories (under 500 words) and uses a clear evaluation rubric.

4. Results: AlphaWrite showed significant improvements:

   • 72% preference rate over initial stories.
   • 62% preference over traditional methods.
   • A recursive self-improvement loop was tested, showing a 56% improvement over the base model.

5. Broader Applications: Beyond narrative fiction, AlphaWrite can be adapted for technical writing, marketing, and other domains, allowing for targeted improvements in specific writing components.

6. Conclusion: AlphaWrite demonstrates that systematic scaling of inference time can enhance creative writing tasks, opening new possibilities for advancing AI writing capabilities.

Dolly Parton's Dollywood Express, a heritage steam train in her theme park, has more riders than the rail systems in 27 U.S. states. Dollywood, which Parton helped develop from a former tourist park, is now a major employer in the area and attracts many visitors. The Dollywood Express operates a 2.5-mile loop with three coal-fired steam engines, running every hour and carrying about 5,000 people daily. This ridership accounts for 92% of all rail riders in Tennessee, excluding Amtrak's single daily train. The article highlights the disparity in ridership between Dollywood's train and public transit, raising questions about national infrastructure priorities.
