Bring Your Own Agent: Your Employees' Assistants Are Already Logged In

The integration of personal AI agents into the workplace is inevitable, creating a new security challenge categorized as Bring-Your-Own-Agent (BYOA). While the tech industry is captivated by tools like OpenClaw, Muse, Instinct, and GrokBot, these personal assistants are quietly accessing corporate environments through methods like OAuth consent, saved browser credentials, and API keys. Unlike the Bring-Your-Own-Device movement where IT departments could formally register and manage physical hardware, personal AI agents often live on vendor servers or blend seamlessly into employee laptops, making them difficult to govern. Many vendors are introducing controls for managed corporate deployments, but these solutions rarely cover truly personal AI agents. Blocking them outright is difficult and prevents employees from realizing significant productivity gains. Instead, organizations should manage these agents by treating identity as the central control plane. By discovering connected shadow AI, linking each agent to a human owner, properly scoping their access, and ensuring their permissions are revoked when the employee departs, companies can safely harness the potential of BYOA. Security teams must adapt to this shift by prioritizing robust identity management over attempting to ban tools that are already entrenched in their networks.


Absence of Evidence: What an AI-Orchestrated Intrusion Harness Teaches Us About AI Detection Engineering

Recent research into SecFlow, a China-nexus AI orchestration harness, offers a critical lesson in AI detection engineering for both attackers and defenders. Developed by a Chinese-speaking operator, SecFlow used AI models like Claude, Qwen, and DeepSeek for reconnaissance, exploitation, and reporting against government and telecom targets. The harness exposed a major flaw in automated workflows: it accepted a worker’s unverified claim of a successful Apache Shiro exploit as ground truth. Because the system assumed plausible output meant actual success without checking its work, more than 27 subsequent tasks were built on this error and consequently failed. This offensive failure mirrors a significant risk for security operations centers (SOCs) relying on AI-generated detection rules. An AI tool can instantly write a rule that is syntactically correct and loads perfectly into a SIEM, giving defenders a false sense of security. However, looking correct is not the same as being operationally effective. Without executing these rules against live attacks to verify they actually fire, defenders risk deploying rules that fail silently. Ultimately, the incident underscores that in automated security engineering, plausible success must never replace proven, tested execution.


A Digital Twin Is Only As Useful As The Decision It Improves

Many digital twin projects in manufacturing fail because teams focus on creating complex, plant-wide virtual replicas instead of solving specific operational problems. According to John Parraga, a digital twin is only truly useful when it targets a single, high-stakes decision by modeling one process using live operational data. The most effective digital twins are modest in scale but deeply practical, connecting to existing systems like PLCs and historians to validate control-sequence changes or diagnose recurring issues without gambling an entire shift of live production. To ensure long-term success, companies must avoid three common pitfalls that quietly erode a model's value. First, teams must prevent scope creep by maintaining strict boundaries around the initial use case. Second, hidden assumptions within the model should be documented clearly so operators understand exactly what the twin is telling them. Finally, because physical equipment and processes naturally change over time, the twin must undergo routine recalibration to prevent model drift. Ultimately, the best approach is to start small by testing one focused use case, proving its value in changing outcomes, and only expanding the twin once that specific process demonstrates measurable, repeatable success on the plant floor.


AI compels organizations to rethink data security

The traditional approach to data security, relying on static firewalls and a digital perimeter, is no longer effective in the age of autonomous artificial intelligence. As these intelligent agents rapidly scan corporate networks to connect information at machine speed, they expose the hidden flaws in older security systems and magnify the risks associated with unclassified legacy data. To maintain control, organizations must adopt a highly strict mindset for these automated programs, tightly locking down their permissions just as they would for regular human employees. Because these digital workers act with inherent curiosity and constantly test the boundaries of a network, conventional identity and access systems fall short. Instead, the focus must shift directly to the data itself. By embedding access rights directly into the metadata, the information becomes self-describing and capable of acting as its own gatekeeper, regardless of the application trying to use it. Furthermore, keeping these development tools in-house rather than relying on external models ensures clear data ownership and far tighter control. Although automation introduces significant complexity and new vulnerabilities, it also provides the solution. Security teams must leverage this same processing power to continuously monitor, detect, and counter automated threats from within their own systems.


Playbook for the Incoming Healthcare Regulatory Regime

Healthcare organizations must prepare for a strict new regulatory environment that will permanently change how they manage cybersecurity. Driven by the Health Care Cybersecurity and Resiliency Act and pending updates to the HIPAA Security Rule, the era of treating essential security measures as optional is finally ending. Soon, all providers will be required to implement multiple factor authentication, encrypt protected health information, conduct regular penetration testing, and maintain continuous network monitoring. While large health systems may adapt smoothly, smaller clinics and rural hospitals face significant financial hurdles. Early estimates suggest initial compliance costs could reach nine billion dollars, yet proposed government grants offer only a fraction of that amount with no funding guarantees. Experts strongly advise against waiting for these regulations to become final before taking action. Instead, organizations should begin immediately by mapping their systems, identifying security gaps, and prioritizing vital upgrades like authentication and data encryption. Special attention must be given to older medical devices and outside vendor contracts, which often harbor the greatest vulnerabilities. Ultimately, adopting these mandatory security practices is no longer just about meeting compliance standards; it is a necessary step to protect sensitive patient information from the growing threat of cyberattacks and data breaches.


The Non-Human Identity Blast Radius: Taming the 45:1 Machine-to-Human Imbalance

In modern digital environments, machine accounts like automated background tasks and system connections vastly outnumber human users, often by a ratio of forty-five to one. While organizations spend significant time and money managing employee access, these non-human accounts are frequently neglected. When an employee leaves a company, their access is promptly removed. However, machine accounts created for temporary projects or testing often remain active indefinitely, holding high-level permissions without any oversight. This creates a major vulnerability. Attackers specifically target these forgotten machine accounts because they bypass standard security measures like two-factor authentication. Once compromised, these accounts provide direct access to core systems while blending in with regular system traffic. To address this risk, organizations need to stop relying on permanent access keys and instead adopt systems that grant temporary credentials only when necessary. Furthermore, companies must manage machine accounts with the same strict discipline they apply to human employees. This means assigning clear human ownership to every machine account, setting expiration dates, automatically removing unused permissions, and regularly scanning for abandoned access points. Ignoring this vast portion of digital activity leaves the door wide open for security breaches, making proper, ongoing management of all automated accounts an absolute necessity today.


When Should You Use Liquid Clustering? Benchmarking Lakehouse Layout Strategies

Choosing the best storage layout for lakehouse analytical systems isn't a one-size-fits-all decision, and getting it wrong can negatively impact both cost and performance. A recent benchmark comparing Liquid Clustering, ZOrdering, and Partitioning on Delta Lake revealed crucial insights into when to use each. While Liquid Clustering generally outperforms the others for point lookups, time-range aggregations, and large aggregations, ZOrdering shines when handling stable, highly selective multi-column workloads where queries consistently filter on the same specific columns. However, ZOrdering has a hidden flaw: if a date column is used as a secondary or tertiary key, time-range queries can slow down significantly because sequential dates get scattered across files. On the flip side, Liquid Clustering can be noticeably slower than ZOrdering when queries are narrow and predictable, as its broader optimization trades exact file pruning for flexibility. Ultimately, Liquid Clustering is recommended as the default for teams with diverse or evolving query patterns because it eliminates the need for manual optimization tasks. Before making a final choice, teams should test their top query patterns against all three layouts to see what works best for their specific data.


From IT Custodian to Business Co-Owner: How Tech Drives the Everyday Operating Model at Tim Hortons GCC

According to Vinay Kumar, Head of IT at Tim Hortons GCC, the role of technology leaders in the quick-service restaurant (QSR) industry has shifted from managing IT systems to driving business outcomes. Technology is now central to everyday operations, and CIOs must ensure their solutions are robust, agile, and easy for frontline staff to adopt. Kumar notes that a seamless customer journey requires connecting multiple backend systems—such as point-of-sale, kitchen displays, and payments—through strong integration architecture and master data management. Furthermore, system reliability during peak hours is critical, requiring a focus on offline capabilities and quick recovery rather than just system uptime. Data and artificial intelligence are also transforming operations by optimizing demand forecasting, inventory planning, and workforce management. However, Kumar cautions that AI should simplify rather than complicate the frontline experience. To achieve success, IT leaders must understand the business deeply, standardize processes, and ensure all systems provide a smooth experience for the customer, who should never have to think about the technology working behind the scenes. In this connected ecosystem, maintaining strong cybersecurity and regulatory compliance across all touchpoints is also vital.


Be a good AI ancestor: Cybersecurity already gave us the playbook

In her recent article, Lisa Thee explains that the technology industry must apply decades of cybersecurity experience to the rapidly evolving field of artificial intelligence. While autonomous AI systems offer significant benefits, they also introduce serious risks like unauthorized actions, security breaches, and data exposure that require practical, technical solutions rather than just high-level ethical guidelines. Thee argues that it is time to move past theoretical discussions about responsible AI and instead establish enforceable boundaries, which she calls "Red Lines." These explicit boundaries clearly define what autonomous systems should never be allowed to do in practice. To achieve this, organizations must empower their engineers, cybersecurity professionals, and legal experts to design, test, and tightly regulate AI safeguards. Just as competing companies have historically collaborated to successfully combat digital crimes, they must now work together across international borders to ensure AI systems operate within safe, verifiable limits. Furthermore, businesses will soon need to provide concrete evidence that their AI tools are secure, leading to the creation of new specialized roles in AI safety and risk assessment. Ultimately, building a secure infrastructure today ensures we leave behind a safe and trustworthy digital environment for future generations to inherit and build upon safely.


Your AI agents can execute every tool call correctly and still break every enterprise rule

The article argues that even when AI agents execute every tool call correctly, they can still violate core enterprise rules because the real risk lies not in the tools themselves but in the decision layer that chooses how and when to use them. It explains that most enterprise AI strategies assume a simple formula — agents plus tools plus data equals agility — but this breaks down in real corporate environments where compliance, governance, and financial controls matter. Tool‑calling makes individual actions deterministic, yet the agent’s reasoning remains probabilistic, meaning it can choose a valid tool sequence that still bypasses labor laws, tax rules, approval workflows, or security boundaries. Attempts to fix this from the outside, such as policy middleware or oversized prompts, lead companies into the “shadow ERP” trap, where they rebuild fragile copies of business logic outside their system of record. The article argues that lawful agents require guardrails at the inference layer: a context engine that filters what the agent can see, a policy engine that enforces business rules, and an execution layer that ensures actions carry the authority of the human the agent represents. The closing message is steady and pragmatic — true enterprise‑grade AI must run where governance already lives, because distance from the system of record weakens both safety and speed.

Do Stablecoins Pave the Way for CBDCs? An Architect’s Perspective

The relationship between regulated stablecoins and CBDCs is complex. Rather than being purely competitive, they may evolve to serve complementary roles in the digital currency ecosystem. Regulated stablecoins excel at facilitating cross-border transactions, supporting decentralised finance applications, and serving as bridges between traditional and crypto financial systems. CBDCs, meanwhile, are likely to focus on domestic retail payments, financial inclusion, and maintaining monetary sovereignty. The regulated stablecoin market has provided valuable lessons for CBDC implementation. Central banks have observed how private stablecoins handle scalability challenges, privacy concerns, and user experience issues. These insights are informing CBDC designs worldwide. However, significant hurdles remain before CBDCs achieve widespread adoption. Technical challenges around scalability, privacy, and security must be resolved. Legal frameworks need updating to accommodate these new forms of money. Perhaps most importantly, central banks must convince the sceptical public that CBDCs will not become tools for surveillance or financial control.


Inside the war between genAI and the internet

One way to stop AI crawlers is via good old-fashioned robots.txt files, but as noted, they can and often do ignore those. That’s prompted many to call for penalties such as infringement lawsuits, for doing so. Another approach is to use a Web Application Firewall (WAF), which can block unwanted traffic, including AI crawlers, while allowing legitimate users to access a site. By configuring the WAF to recognize and block specific AI bot signatures, websites can theoretically protect their content. More advanced AI crawlers might evade detection by mimicking legitimate traffic or using rotating IP addresses. Protecting against this is time-consuming, forcing the frequent updating of rules and IP reputation lists — another burden for the source sites. Rate limiting is also used to prevent excessive data retrieval by AI bots. This involves setting limits on the number of requests a single IP can make within a certain timeframe, which helps reduce server load and data misuse risks. Advanced bot management solutions are becoming more popular, too. These tools use machine learning and behavioral analysis to identify and block unwanted AI bots, offering more comprehensive protection than traditional methods.


How AI enhances security in international transactions

Rather than working with pre-set and heuristic rules, AI learns from transaction patterns in real time. It doesn’t just flag transactions that exceed a certain limit—it contextualises behaviour. ... If the transaction is genuinely out of place, AI doesn’t immediately block it but escalates it for real-time review. This ability to detect anomalies with context is what makes AI so much more effective than rigid compliance rules. ... One of the biggest pain points in compliance today is false positives, transactions wrongly flagged as suspicious. Imagine a business that expands into a new market and suddenly sees a surge in inbound transactions. Without AI, this might result in an account freeze. But even AI-powered systems aren’t perfect. A name match in a sanctions list, for instance, doesn’t necessarily mean the customer is a fraudster. If John Doe from Mumbai is mistakenly flagged as Jon Doe from New York, who was implicated in a financial crime, a manual review is still necessary. ... AI isn’t here to replace compliance teams, it’s here to empower them. Instead of manually reviewing thousands of transactions, compliance officers can focus on high-risk cases while AI handles routine screening. What does the future look like? Faster, real-time transaction approvals – AI will further reduce manual interventions, making cross-border payments almost instantaneous.


DiRMA: Measuring How Your Organization Manages Chaos

DiRT is a structured approach to stress-testing systems by intentionally triggering controlled failures. Originally pioneered in large-scale technology infrastructures, DiRT helps organizations proactively identify weaknesses and refine their recovery strategies. Unlike traditional disaster recovery methods, which rely on theoretical scenarios, DiRT forces teams to confront real operational disruptions in a controlled manner, ensuring that failure responses are both effective and repeatable. The methodology consists of performing a coordinated and organized set of events, in which a group of engineers plan and execute real and fictitious outages for a defined period to test the effective response of the involved teams ... DiRMA is inspired by the program DiRT, created in 2006 by Google to inject failures in critical systems, business processes and people dynamics to expose reliability risks and provide preemptive mitigations. Since some organizations have already started their journey toward the creation of environments for DiRT, in which they can launch failures, determine their level of resilience and test their incident response processes, it is essential to have frameworks, like CE Maturity Assessments, to evaluate the effectiveness, in this case, of a program like DiRT.


The RACI matrix: Your blueprint for project success

The golden rule of a RACI matrix is clarity of accountability. Because of this, as mentioned previously, only one person can be accountable for a given project. In many projects, the concept of responsibility and accountability can get conflated or confused, especially when those responsible for the project’s completion are empowered with broad decision-making capabilities. The chief difference between R (responsible) and A (accountable) roles is that, while those deemed responsible may be given latitude for decision-making when completing the work involved in a task or project, only one person truly owns and signs off on the work. ... RASCI is another type of responsibility assignment matrix used in project management. It retains the four core roles of RACI — Responsible, Accountable, Consulted, and Informed — but adds a fifth: Supportive. The Supportive role in a RASCI chart is responsible for providing assistance to those in the Responsible role. This may involve providing additional resources, expertise, or advice to help the Responsible party complete a particular task. Organizations that choose RASCI often do so to ensure that personnel who may not have direct responsibility or accountability but are nevertheless vital to the success of an activity or project are considered a notable facet (and cost) of the project. 


How to create an effective crisis communication plan

Planning crisis communication involves many practical aspects. These include, for example, identifying the room in which live crisis management meetings can take place and how online meetings will be conducted. In the event of a cyber crisis, it must always be taken into account that communication tools such as email, chat, landline, or IP telephony may not be available. It must also be expected that the IT network will be inaccessible or will have to be shut down for security reasons. Therefore, all prepared documents and contact lists of the crisis team must be accessible even without access to the internal IT network. ... Crucial to effective external communications is that the media and social network users receive information from a single source. Therefore, it must be clarified that only designated corporate communications employees with experience in public relations will provide statements to the media. All departments must be informed of their media contact details. Press relations during a crisis are generally conducted in multiple stages. Immediately upon the outbreak of a crisis, a prepared statement must be made available and issued on request. This statement may not contain details about the incident itself, but must express a willingness to engage in open communication.


Tapping into the Unstructured Data Goldmine for Enterprise in 2025

With so much structured data on hand, companies may believe unstructured data doesn’t add value, which couldn’t be farther from the truth. In fact, unstructured data can provide deeper insights and put companies ahead of the competition. However, before that happens, organizations must get a handle on all of the data they have on hand. While the majority of unstructured data is digital, some businesses have a large number of paper records that haven’t yet been digitized. By using a combination of software and document scanners, hard copies can be scanned and integrated with unstructured data. This may seem like too much of an investment from a time and resource perspective, and a heavy lift for humans alone; however, AI can fundamentally change how companies leverage unstructured data, enabling organizations to extract valuable insights and drive decision-making through human/machine collaboration. ... There’s no doubt that effectively managing unstructured data is critical to a successful and holistic data management program, but managing it can be complex, overwhelming, resource-intensive and difficult to analyze because it doesn’t fit neatly into traditional databases. Unlike structured data, which can easily be turned into business intelligence, unstructured data often requires significant processing before it can provide actionable insights.


Advances in Data Lakehouses

Recent advancements in data lakehouse architecture have significantly enhanced data management and quality through innovations like Delta Lake, ACID transactions, and metadata management. Delta Lake acts as a storage layer on top of existing cloud storage systems, introducing robust features such as ACID transactions that ensure data integrity and reliability. This enables consistent read and write operations, reducing the risk of data corruption and making it easier for organizations to maintain reliable datasets. Additionally, Delta Lake supports schema enforcement and evolution, allowing for more flexible data handling while maintaining structural integrity. Metadata management in a data lakehouse context provides a comprehensive way to manage data assets, enabling efficient data discovery and governance. ... In the rapidly evolving landscape of data management, improving query performance and enhancing SQL compatibility are crucial for modern data stacks, especially within the framework of data lakehouses. Data lakehouses combine the best of data lakes and data warehouses, providing both the scalability of lakes for raw data storage and the structured, efficient querying capabilities of warehouses. A primary focus in this area is optimizing query engines to handle diverse workloads efficiently.


Self-Healing Data Pipelines: The Next Big Thing in Data Engineering?

The idea of a self-healing pipeline is simple: When errors occur during data processing, the pipeline should automatically detect, analyze, and correct them without human intervention. Traditionally, fixing these issues requires manual intervention, which is time-consuming and prone to errors. There are several ways to idealize this, but using AI agents is the best method and a futuristic approach for data engineers to self-heal failed pipelines and auto-correct them dynamically. In this article, I will show a basic implementation of how to use LLMs like the GPT-4/DeepSeek R1 model to self-heal data pipelines by using LLM’s recommendation on failed records and applying the fix through the pipeline while it is still running. The provided solution can be scaled to large data pipelines and extended to more functionalities by using the proposed method. ... To ensure resilience, we implement a retry mechanism using tenacity. The function sends error details to GPT and retrieves suggested fixes. In our case, the 'functions' list was created and passed to the JSON payload using the ChatCompletion Request. Note that the 'functions' list is the list of all functions available to fix the known or possible issues using the Python functions we have created in our pipeline code. 


Android financial threats: What businesses need to know to protect themselves and their customers

Research has revealed an alarming trend around Android-targeted financial threats. Attackers are leveraging Progressive Web Apps (PWAs) and Web Android Package Kits (WebAPKs) to create malicious applications that can bypass traditional app store vetting processes and security warnings. The mechanics of these attacks are sophisticated yet deceptively simple. Victims are typically lured in through phishing campaigns that exploit various communication channels, including SMS, automated calls, and social media advertisements.  ... Educating customers is a vital step. Businesses can empower customers by highlighting their own security efforts, like two-factor authentication and secure transactions. By making security part of their brand identity and providing supportive resources, small and mid-size businesses can create a safe, confident experience for their customers. Strengthening internal security measures is equally important though. Small businesses should consider implementing mobile threat detection solutions capable of identifying and neutralizing malicious PWAs and WebAPKs. Additional measures include collaborating with financial partners, sharing intelligence on emerging threats and developing coordinated incident response plans to address attacks quickly and effectively.
