Durable Streams is an open protocol that provides real-time sync to client applications. It supports catch-up reads and live tailing. The protocol works anywhere HTTP works, and it is built on standard HTTP with no custom protocols. Durable Streams is built for production scale. It complements backend streaming systems by reliably streaming data to client applications.

The first step focuses on learning to enumerate active processes, opening them, and retrieving their module names programmatically. This is done through Windows API functions like `EnumProcesses`, `OpenProcess`, `EnumProcessModules`, and `GetModuleBaseNameA` while managing Rust's `unsafe` code.

Startups in 2026 will focus on transforming unstructured multimodal data into structured formats, automating cybersecurity tasks to close hiring gaps, and developing agent-native infrastructures for AI workloads. AI will also enhance creative tools for seamless storytelling across media, redefine data stacks with AI-native features, and push traditional systems of record into the background in favor of dynamic agent-led execution environments. Vertical AI will evolve into multi-party collaborations, agents will prioritize machine legibility over human interface design, and personalized experiences will become the norm, culminating in AI-native universities and interactive storytelling worlds.
You've got an idea, and you're convinced it's great. You want to start building right now. This is how founders waste months on things nobody wants. PostHog's founders pivoted five times, and most of those ideas never made it past a single conversation. The trap is asking people if they like your idea - they'll say yes just to make you go away. Instead, find out if they've actually had the problem and tried to solve it themselves. If they built some crappy internal system to deal with it, there's probably a business there. If it's not a hair-on-fire problem for them, move on.
Make help requests specific, finite, and actionable to increase the chances of receiving assistance. Requests should clearly define the commitment, showing preparation and ensuring the help will be impactful. Avoid open-ended asks and demonstrate you have taken steps on your own, and value the helper's input.
Why do brilliant teams often plateau at $20M ARR? It isn't a lack of effort—it's usually a lack of Single-Threaded Ownership. If two people own a goal, no one does. This guide details how to build performance infrastructure: hire for "capacity" (driving initiatives start-to-finish), define specific actions that violate your values (like saying "that's not my job"), and ensure every objective has exactly one owner so performance is always visible.

AI has opened up the potential for real innovation, but founders are still building specialist AI products as if they were building the same subscription software tools of the last decade. Specialization will eventually lose out to simpler systems with more compute and more training data. The businesses that will define this era will be the companies that build what models need to get better, or companies that discover work that's only possible because of AI.

Today's phishing attacks involve AI-generated voices, videos, and interactive deepfakes of company executives. They fool 99% of people.
A coordinated phishing campaign that ran from April to November targeted at least 18 US universities using approximately 70 domains and the Evilginx adversary-in-the-middle toolkit. Attackers sent personalized emails containing TinyURL-shortened links that impersonated university SSO portals to steal MFA-bypassing session cookies. UC Santa Cruz, UC Santa Barbara, University of San Diego, Virginia Commonwealth University, and University of Michigan were among the most heavily targeted. Recommended mitigations include adopting phishing-resistant MFA (FIDO2/WebAuthn) and monitoring unusual session cookie behavior.
Vitas Healthcare, the largest US for-profit hospice chain, reported that a compromised vendor account was used to access its systems from late September to late October, exposing data belonging to over 300,000 current and former patients. Exposed information includes contact details, identification numbers, Social Security numbers, medical and insurance data, and next-of-kin contacts. No ransomware group has claimed responsibility.
Ivanti disclosed a critical vulnerability in its Endpoint Manager (EPM) platform that allows unauthenticated attackers with access to the EPM web service to register fake endpoints and inject malicious JavaScript into the administrative dashboard. Ivanti also patched three additional high-severity vulnerabilities, including two that could enable unauthenticated remote code execution on arbitrary systems.
A security researcher released a Sysmon configuration tailored to detect Remote Monitoring and Management (RMM) tools listed in the LOLRMM framework. The rules cover process creation, file operations, network activity, and DNS queries, derived from behavioral analysis of RMM installers executed in VirusTotal, Hybrid-Analysis, and Any.run sandboxes. By capturing file paths, registry keys, and network indicators, the configuration helps security teams spot unauthorized RMM activity even when binaries are renamed or obfuscated.
The UK NCSC explains that prompt injection fundamentally differs from SQL injection because LLMs do not separate instructions from data, they simply predict tokens. As a result, techniques like parameterized queries cannot fully mitigate prompt injection. The agency recommends treating LLMs as "inherently confusable deputies" and implementing deterministic guardrails that constrain system actions outside of the model rather than relying on input filtering. Effective defenses include enforcing least privilege for LLM-driven workflows, closely monitoring tool and API usage, and acknowledging that prompt injection remains a residual architectural risk.
Risk-Based Alerting (RBA) allows analysts to combine multiple lower-fidelity alerts into a single higher-confidence incident by assigning risk scores to alerts that do not individually generate incidents. An incident is only created once a cumulative risk threshold is met. When assigning scores, teams should weigh potential impact, the criticality of the asset or user involved, and the confidence that the behavior reflects real malicious activity. This approach can reduce alert fatigue and improve triage efficiency.

Twin brothers Muneeb and Sohaib Akhter, federal contractors previously convicted of hacking in 2015, were arrested for allegedly deleting nearly 100 government databases containing FOIA records and sensitive investigative files. After learning of their termination from Opexus, the pair allegedly used still-active credentials to access systems. Authorities say Muneeb also stole IRS tax records of 450 individuals and attempted to erase evidence via AI-assisted log deletion queries. The case underscores the need for immediate credential revocation on termination, rigorous vetting for privileged roles, and strong backup strategies.
Russian threat actor UTA0355 impersonated multiple prominent European security conferences, including the Belgrade Security Conference and Brussels Indo-Pacific Dialogue, to harvest Microsoft 365 credentials. The attackers created convincing replica websites and abused OAuth and Device Code authentication flows. They used rapport-building outreach on WhatsApp and Signal, leveraged compromised accounts for credibility, and selectively triggered credential theft based on targeted email domains. Defenses include user training on OAuth consent prompts, monitoring anomalous device registrations in Entra ID, and enforcing conditional access controls.
Security researchers report a 700% increase in ransomware attacks targeting hypervisors like Hyper-V and VMWare ESXi, with groups such as Akira leading the trend. Hypervisors often lack endpoint-style protections and offer attackers a control point over numerous VMs simultaneously. Attacks abuse built‑in tools to encrypt VM storage and misuse management utilities to disable protections.
