YOUR DATA AGENTS NEED CONTEXT

The market is aware that a lack of context is a problem, but it is still in the early stages of building solutions. Building a proper data agent is a blend of technical challenges related to data infrastructure and engineering and human operational challenges related to tribal knowledge collection. This post proposes a modern context layer paired with an agentic data system. Not every enterprise will build this in-house, so the market is open for an external solution.

MEETINGS ARE PRODUCTS

Everyone should tend to their recurring meetings the way they would tend to any other product they were responsible for. This can reveal unnecessary meetings or issues that no one thought to question. Some meetings only exist because the highest-paid person in the room decided that's how things work. However, attendees can usually adjust the who, what, how, or when these meetings occur.

THE ONLY PITCH PREP YOU'LL EVER NEED

Redbud VC's pre-seed framework prioritizes how founders reason under pressure over rehearsed answers. Sharpest signals include naming credible failure modes, articulating uncomfortable market beliefs, and showing how customer feedback has changed their thinking. The strongest indicator of success is the ability to say "I don't know" and explain the plan to find out, as early companies typically fail from misjudging reality and updating too slowly.

WHITE COLLAR GOES BLUE

Your autonomy, your creative ownership, your seat at the table - none of that was ever a right. It was compensation for being hard to replace. A startup founder recently admitted their core team could just do the work themselves with AI, and dealing with ten personalities on a spectrum of competence isn't worth it anymore. You can't walk into a one-on-one and say, "Actually, we just need you to execute now and stop having opinions." So companies are resetting instead. Lay people off, restructure, and rehire the same roles but scoped as trades from the start.

THE ORG CHART MATH BEHIND AI-NATIVE SPEED

Metcalfe's Law states that each new team member adds n-1 new connections. This means there are 11,175 potential communication channels in a traditional 150-person organization. An AI-enabled team producing equivalent output might need 30 people, dropping potential communication channels down to 435, a 96% reduction. AI-native startups are pulling ahead because fewer humans means fewer channels and faster iteration, compounding speed.

FAKE CLEANMYMAC WEBSITE SPREADS SHUB STEALER THROUGH CLICKFIX TERMINAL TRICK

A fraudulent CleanMyMac site uses a ClickFix-style social engineering technique to trick macOS users into pasting a malicious Terminal command that silently installs SHub Stealer, bypassing Gatekeeper entirely. The stealer harvests macOS Keychain credentials via a fake system authentication prompt, targets Exodus, Atomic Wallet, Ledger Live, and Trezor Suite for seed-phrase extraction, and persists via a LaunchAgent disguised as a Google software updater that runs every minute. Russian-language keyboard layouts trigger immediate self-termination, a common indicator of Russian-nexus cybercriminal origin.

ERICSSON US DISCLOSES DATA BREACH AFTER SERVICE PROVIDER HACK

Swedish telecom giant Ericsson disclosed that it had suffered a data breach affecting over 16k individuals whose data was held by a third-party service provider. The breached data includes names, addresses, SSNs, driver's license numbers, government-issued ID numbers, financial information, medical information, and dates of birth. No cybercrime group has claimed the breach, suggesting that the third party may have paid the ransom, or the cybercriminals could not link the data to Ericsson.

HOW TO SCAN FOR VULNERABILITIES WITH GITHUB SECURITY LAB'S OPEN SOURCE AI-POWERED FRAMEWORK

GitHub Security Lab's open source Taskflow Agent employs a multi-stage LLM pipeline — threat modeling, issue suggestion, and thorough audit — to detect high-impact auth bypasses, IDORs, and logic flaws with a low hallucination rate. It has identified over 80 vulnerabilities across more than 40 repositories so far. Out of 1,003 suggested issues, only 21% met the criteria for impactful reporting, with business logic flaws having the highest true-positive rate at 25%, and IDOR issues exceeding combined XSS and CSRF cases. Notable confirmed findings include a privilege escalation in Outline (CVE-2025-64487), PII exposure in WooCommerce (CVE-2025-15033) and Spree (CVE-2026-25758), and a universal authentication bypass in Rocket.Chat's microservices DDP layer (CVE-2026-28514) caused by a missing await on a bcrypt Promise.

FROM A SOPHISTICATED BROWSER-EXTENSION SUPPLY-CHAIN COMPROMISE TO A VIBECODED TWIST: A CHROME EXTENSION AS THE INITIAL ACCESS VECTOR FOR A BROADER MALWARE CHAIN

The Featured Chrome extension ShotBird (ID: gengfhhkjekmlejbhmmopegofnoifnjp) was weaponized after an ownership transfer between December 2025 and March 2026, transformed into a remote-controlled malware channel that beaconed to api.getextensionanalytics.top, stripped CSP/X-Frame-Options headers via declarative rules.json, injected fake Chrome update lures, and exfiltrated form data including passwords, card/CVV, IBAN, and SSN fields. The file-delivery path dropped googleupdate.exe (SHA256: E8D2ED43...), a WiX Burn bootstrapper bundling a legitimate Google-signed ChromeSetup.exe alongside a stager psfx.msi that decoded to irm orangewater00.com|iex. PowerShell Script Block Logging (Event ID 4104) reconstructed a second stage from 115 fragments, revealing ETW suppression via PSEtwLogProvider, Windows Credential Manager enumeration, Chromium Login Data and Web Data targeting, and exfiltration routines — with infrastructure and endpoint patterns overlapping a parallel campaign involving the QuickLens extension documented by Annex Security.

AN IPHONE-HACKING TOOLKIT USED BY RUSSIAN SPIES LIKELY CAME FROM US MILITARY CONTRACTOR

The 23-component iPhone exploit toolkit dubbed "Coruna" — targeting iOS 13 through 17.2.1 — has been traced by former employees and iVerify researchers to L3Harris's Trenchant division, originally built for Five Eyes intelligence customers. Former Trenchant GM Peter Williams, sentenced to seven years last month, sold eight company tools to Russian zero-day broker Operation Zero for $1.3M, providing a likely path by which Coruna reached Russian espionage group UNC6353 and later Chinese cybercriminals. Two Coruna exploits (Photon and Gallium) have also been linked to Operation Triangulation, the sophisticated iOS campaign first disclosed by Kaspersky in 2023.

THE MCP AUTHN/Z NIGHTMARE

Doyensec maps the full OAuth 2.0/dynamic client registration attack surface in MCP deployments, covering tool poisoning, rug pulls, schema poisoning, prompt injection via tool responses, command injection (CVE-2025-53100, CVE-2025-53818), SSO metadata manipulation (CVE-2025-4144, CVE-2025-4143), DNS rebinding against unauthenticated localhost WebSocket servers, and OIDC discovery endpoint abuse. The proposed Identity Assertion JWT Authorization Grant (JAG) enterprise authorization model introduces four unresolved risks: no token revocation path for misbehaving agents, LLM-driven scope escalation without user consent, undefined client credential issuance enabling scope namespace collision and resource identifier injection, and ID-JAG replay amplifying blast radius across multiple MCP access tokens. Security teams auditing MCP deployments should treat every step of the authorization chain as an injection point and prioritize mTLS/certificate-based trust anchors, strict resource namespacing, centralized access invalidation, and explicit per-action consent gates for high-risk tool calls.

AGENT SAFETY IS A BOX

AI agents are highly flexible and adaptable systems that can affect the outside world via side effects. To effectively secure these workflows, we need to add a deterministic “box” around the agent. In a cloud environment, agents can run in an AgentCore Runtime, which utilizes an AgentCore Gateway to restrict the access an agent has outside of the “box,” and an AgentCore Policy can be utilized to grant the agent authorization to use specific tools in a specific way.

A DEFINITIVE GUIDE TO VIDEO HOOKS

Strong social media videos rely on 3 hooks in the first few seconds to capture attention. Start with a text on screen hook that quickly signals what the video will cover, often through a question or cliffhanger. Pair it with a concise spoken hook that includes key words and delivers the message immediately, since viewers decide quickly whether to keep watching. Add a visual hook through movement or editing, such as zooms, transitions, or dynamic framing, to create curiosity and keep the viewer engaged.

OUR MARKETING TEAM IS MOVING TO GITHUB

The Head of Marketing at BizMachine moved the team's marketing infrastructure from Google Drive to GitHub because their AI-driven workflows had grown too complex for a shared drive. The team manages numerous AI agents, skills, context files, and automations that require reliable collaboration and change tracking. Google Drive lacked version control and structured review, making it difficult to manage updates as the team grew. GitHub provides version history, pull requests, and testing branches, allowing workflows to be updated and tested safely, similar to how engineering teams manage shared infrastructure.

WHEN PEOPLE ARE MOST LIKELY TO SWITCH BRANDS

Consumers are most likely to switch brands after they gain some experience in a product category but before they become experts. Analysis of 3.7 million product reviews across nearly 30 years showed that confidence follows an inverted U pattern as experience grows. People were 4.5% more likely to switch makeup brands after reviewing 2 to 10 products, and 54% of people who switched never returned. The research shows that prompting customers to reflect on product quality or benefits can increase confidence and reduce switching.

CHECKING AN LLM'S WORK IS A SYSTEMIC, NOT AN INDIVIDUAL, PROBLEM

LLMs increase output speed but weaken problem definition when teams skip critique and rely on AI-generated prototypes. Tools like ChatGPT spread quickly because they fit workflows that reward speed and visible activity instead of real progress. AI can generate code or designs in seconds, but the output is statistically average and cannot signal when it fails. Humans must review every result, and constant checking increases mental fatigue and burnout. The typical AI prototype workflow lacks a structured design critique, where people question the purpose of a design, examine why decisions were made, and test whether the solution actually solves the user's problem.

HOW I STOPPED BORING PEOPLE WITH MY CONTENT

To make content compelling, focus on finding a specific angle rather than just covering a topic. Avoid “everyday angles” that are common statements your audience has seen many times. Instead, create a “payday angle” by identifying a specific problem your audience faces, uncovering an unexpected or counterintuitive truth about it, and presenting a better path forward. This requires customer research and listening to sales calls. A strong payday angle interrupts expectations and provides insight competitors aren't offering, ensuring your work is noticed.
