Hacker Noon Cybersecurity

Free VPNs aren’t free. Someone pays for every server, every IP address, every gigabyte of traffic. When you don’t pay with money, you pay with your data, your bandwidth, or sometimes your identity. To make you understand this better, I’ll break down the actual infrastructure economics with real numbers and documented cases in this article.Read All

Current Breach and Attack Simulation (BAS) tools just replay static scripts and generate PDFs. VANGUARD uses an LLM ReAct loop to autonomously hack targets, adapting to what it finds and streaming its reasoning live via SSE. After the assessment, it automatically synthesizes and deploys Elasticsearch KQL rules to catch the exact vulnerabilities it just exploited.Read All

• Pricing systems at scale fail not only due to logic, but due to unstable network behavior • DNS inconsistency, routing issues, and external blocking introduce financial risk • Traditional VPNs are not designed for deterministic execution in financial systems • We built a custom network control layer with: – controlled DNS for critical domains – segmented routing policies – secure server-to-server connectivity – resilience under network disruption • Network design became part of financial risk management, not just infrastructure • Result: more predictable execution, reduced anomalies, and safer pricing operations Read All

Modern AI tools like Claude Code, Codex, or even the browser-based ChatGPT and Claude.ai often run npm install behind the scenes to make the things you ask for. If you asked an AI to “make me a weather app,” it might have pulled in Axios as a transitive dependency. You never saw the command, and you never approved the install.Read All

The base is a reflection of current scale, a strategic platform that can be leveraged to introduce, cross-sell, and upsell future-ready security solutions acrosRead All

The cybersecurity industry isn’t 72 companies — it’s 25 companies filling 72 foundational roles across a layered value chain from identity and endpoint at the edge to SIEM, SOAR, and managed services at the core. The most consequential vendors — Palo Alto Networks, Microsoft, IBM, AWS, Google Cloud, Broadcom, and Datadog — appear multiple times because they’ve built platforms spanning the entire chain. Platform consolidation, cloud providers as default security vendors, and an attack surface expanding faster than the defense are the three forces reshaping who wins.Read All

Code audits catch bugs, not systemic risk. Resolv, Bybit, GMX, WazirX lost $100M+ to threats no audit would find: compromised keys, governance blind spots, infrastructure failures. Threat modelling identifies how your system fails, prioritizes which risks matter most, and produces a roadmap. Build it before launch, maintain it forever. The difference between companies that get hacked and companies that don’t.Read All

ClickFix attacks have become increasingly popular among cybercriminals. They trick users into connecting their Macs to a malicious criminal network. Moonlock Lab uncovers a sophisticated ClickFix scheme that uses fake VC firms and personas to target crypto professionals with fake job opportunities.Read All

I deployed a staking vault on Sepolia and got it verified on Etherscan with a green checkmark. The source code contains a storage write that does not exist in the compiled bytecode, due to a known Solidity optimizer bug (SOL-2022-7). The verification confirms the build is reproducible. It does not confirm the bytecode does what the source says. Read All

A 56,000-star LLM app ships with raw string concatenation in its database connector. I found it, reported it, got the CVE. Here is the whole story and why it matters beyond the bug.Read All

Why developers are ditching bloated agent protocols and turning to the CLI as the most practical foundation for building AI agents in 2026.Read All

CIC Private Debt’s new risk hire signals how private credit firms are preparing for a tougher cycle where operations may matter as much as returns.Read All

TL;DR: The GlassWorm campaign compromised 151+ GitHub repos and 72+ VS Code extensions in March 2026 using invisible Unicode payloads, AI-generated camouflage, and blockchain-based command infrastructure. As a solo developer running a Next.js app in production, I walked through what I checked, what I changed, and why indie builders can no longer ignore supply chain security.Read All

Gcore data highlights a threat landscape defined by newfound automated attack capabilities, scale, and frequency. Technology remains the most targeted sector, accounting for 34% of attacks, followed by financial services (20%) and gaming (19%).Geographic patterns show a strong concentration of attack sources in Latin America.Read All

Traditional signature-based tools fail against zero-day attacks. We built a behavioral anomaly detection system using AWS Lambda, SageMaker, and API Gateway for our Java microservices. Results: 94% accuracy on known attacks, 78% zero-day detection, sub-100ms latency. This article covers feature engineering, model training with Random Cut Forest, real-time response automation, and lessons on false positive tuning. Includes code examples for telemetry emission, Lambda authorizers, and deployment architecture. Read All

New Report Highlights Surge in Exposed API Keys, Session Tokens, and Machine Identities. Report shows attackers are increasingly targeting machine identities and authenticated session artifacts.Read All

AI security is the biggest tech challenge of the next decade because probabilistic systems break traditional security boundaries. We examine real attack vectors like prompt injection and training data poisoning plus practical defenses including semantic input validation and behavioral monitoring. Learn why signature-based tools fail against AI attacks and how to build layered security for machine learning pipelines in production. Read All

Private companies are becoming strategic targets in global cyber operations. Cyber operations serve as both telescope and excavation tool for intelligence efforts. Cyber attacks are also contributing to a rising tide of cyber activity targeting major national powers. Read All
