AGENCY IS THE LAST FRONTIER

Despite unprecedented access to knowledge, tools, and capital, most people fail to act and achieve meaningful outcomes. The limiting factor today is agency, the willingness to start, iterate, and learn by doing. High-agency people close the gap between what's possible and what actually happens. Capital, AI tools, and information are abundant, but action remains rare and is the key differentiator. Stop waiting and begin building now.

VERTICAL SOFTWARE ALREADY WON THE CONTEXT GRAPH

Vertical software companies have been building context graphs, crucial for autonomous agents, by capturing specific business decisions for over a decade. Unlike horizontal platforms with broad, flexible data models, vertical software uses industry-specific ontologies to record reasoning and integrate functions, making decision traces more reconstructible. As AI and embedded services grow, vertical platforms hold a strategic advantage over horizontal SaaS and agent-first startups, with their deeply established context graphs.

HIBP ADDS ALLEGED UNDER ARMOUR DATA BREACH IMPACTING 72 MILLION EMAILS

Have I Been Pwned added an alleged Under Armour breach attributed to the Everest ransomware group that exposed 72.7 million unique email addresses along with names, dates of birth, physical addresses, and purchase history from a 343GB exfiltration in November. The data was published after Under Armour reportedly did not pay the ransom, with the dataset now circulating on underground forums and indexed by DeHashed. Affected users should monitor for targeted phishing impersonating order-related communications and change reused passwords.

CISCO FIXES UNIFIED COMMUNICATIONS RCE ZERO-DAY EXPLOITED IN ATTACKS

Cisco has announced a new vulnerability impacting United Communications, Cisco Unity Connection, and Webex Calling Dedicated Instance. The vulnerability is due to improper validation of user-supplied input in HTTP requests that could allow an attacker to obtain access to the underlying system via a sequence of specially crafted HTTP requests. The patches are version-specific, so admins should check the README before applying patches.

HACKERS EXPLOIT SECURITY TESTING APPS TO BREACH FORTUNE 500 FIRMS

Automated pentest company Pentera discovered nearly 2K instances of exposed security testing apps, such as OWASP Juice Shop and DVWA, publicly exposed in the networks of Fortune 500 companies. Many of these web apps are used for security training and are deployed in cloud environments with overly permissive IAM roles and default credentials. Pentera found evidence that 20% of exposed DVWA apps had malicious artifacts such as webshells and cryptominers deployed.

IS THAT ALLOWED? AUTHENTICATION AND AUTHORIZATION IN MODEL CONTEXT PROTOCOL

Remote MCP servers should implement the OAuth 2.1 Authorization Code grant with PKCE for client authentication, leveraging protected resource metadata (RFC 9728) and authorization server discovery (RFC 8414) for the handshake. The 2025-11-25 MCP specification introduces step-up authorization for scope negotiation and recommends Token Exchange for downstream service authentication, while explicitly prohibiting token passthrough. Organizations deploying MCP servers should design granular scopes with clear read/write/delete separation, ensure short-lived access tokens, and implement proper validation, including checks for issuer, audience, and expiration.

VULNERABILITY PRIORITIZATION BEYOND THE CVSS NUMBER

CVSS scores alone fail to capture how vulnerabilities propagate through interconnected systems. Log4Shell is an example in which widespread nested dependencies, not just technical severity-driven impact, are at play. The Unified Linkage Model (ULM) framework evaluates vulnerabilities based on adjacency, inheritance, and trust relationships to identify "blast radius multipliers," such as SSO services or CI/CD pipelines. Security teams should map system dependencies and prioritize patching vulnerabilities near identity systems and shared services that can amplify downstream risk.

KEEPING SECRETS OUT OF LOGS

Secrets often end up in logs from a variety of sources, such as forgotten debugging lines, excessive error logging, and telemetry. Some fixes include architecting to reduce logging sinks, using domain primitives to abstract secrets, using read-once objects, using log preprocessors, adding unit tests, and implementing taint tracking. To prepare for a logging overhaul, teams should first lay the foundations of the initiative, understand the data flow, protect data at choke points, apply defense-in-depth, and plan for response and recovery in the event of leaked secrets.

DON'T TRIP[WIRE] YOURSELF: TESTING ERROR RECOVERY IN ZIG

Tripwire is a Zig library for injecting failures at named points in code to test `errdefer` error handling paths, which are typically untested and a consistent source of resource leaks and memory corruption. The library uses comptime to completely optimize away in non-test builds, producing zero runtime cost in production. Integration into Ghostty immediately uncovered approximately six `errdefer` bugs that had never manifested in production.

THE YEAR OF THE GREAT FRACTURE

2026 is shaping up as a year of fracture, where the “middle” has collapsed. The average customer no longer exists. Markets are splitting into clear extremes with different needs, resources, and behaviors. AI is commoditizing speed and efficiency, making trust the only real moat. Influence is moving from public platforms to private, owned channels. The winners are decisive operators who pick a side and act while others keep hedging.

E-COMMERCE TIP: WIN BACK LOST CUSTOMERS AFTER CANCELLED ORDERS

After a customer has refunded or cancelled an order, send a survey email asking for the reason. Provide the most common answers that are simple to decide between, and use links to collect the response. Once the user clicks a link, save that option under their profile. From that, create a Cancelled/Refunded Order Winback Flow with personalized emails based on the survey answer they selected.

HOW TO GENERATE AN EXTRA $1M FROM RETENTION

Focus on fixing what is already broken instead of sending more campaigns. Identify where customers drop off, which products drive churn, and what delivery or support issues create friction. Lock in core flows like welcome, post-purchase, abandoned cart, replenishment, and winback before increasing broadcasts. Simplify segmentation and sharpen messaging so value is clear. Use post-purchase email to reduce regret and set expectations. Maintain a tight learning loop where every send drives a clear decision.

HOW MODERN ANIMAL GOT 50M VIEWS IN THREE MONTHS

Instead of educational or polished brand content, Modern Animal shifted to filming veterinarians mic'd up during real appointments, capturing candid conversations and behavior that viewers normally never see in veterinary clinics. Led by a two-person creative and social team, the strategy relied on multi-angle footage and minimal editorial framing, which helped a single post break out to 25M+ views and accelerate follower growth. The visibility translated into higher site traffic during viral periods and increased comfort among potential customers who said the content reduced anxiety about what happens when pets go “in the back”.

YOUTUBE DISTRIBUTION IS TILTING TOWARD SHORTS, PRESSURING LONG-FORM REACH, DATA SUGGESTS

YouTube distribution is shifting toward Shorts, which is cutting long-form reach for many creators. Analysis of more than 500 channels shows average long-form views fell from about 150,000 to about 60,000 per upload, and the top 100 YouTubers saw a roughly 50% view drop in one week. Homepage space for long-form videos shrank from about ten slots in 2024 to two or three in 2025, while Shorts visibility from homepage and search roughly doubled versus 2024. Older Shorts now lose promotion after about 30 days, and AI-generated channels add pressure by capturing 63 billion views and an estimated $117 million in annual revenue. These shifts concentrate long-form views among fewer channels and raise sustainability risks since Shorts earn less revenue and require higher output.

ANTI-ENGAGEMENT

A new generation of creators is redefining influence by embracing mystery instead of full transparency. They use anti-engagement strategies like erratic posting, faceless profiles, and selective disclosure. This makes audiences actively seek them out. Followers form devoted, idea-driven communities rather than casual fans. Influence is based on a worldview or aura, not lifestyle visibility. By resisting algorithms and controlling access, these creators make their presence compelling through what is withheld.

GENAI, THE SNAKE EATING ITS OWN TAIL

AI weakens the ecosystems it relies on. Models trained on human content extract value without attribution or revenue for creators. This accelerates the decline of open source and publishing. The result is a broken incentive loop that risks a long-term content collapse. A proposed fix is pay-per-use AI, with source citations and revenue sharing, so creators, users, and AI companies all benefit.
