Gate has partnered with Visa to launch a crypto-linked card, allowing users to make payments with digital assets online and in-store wherever Visa is accepted. The card will be available across 40+ markets globally, further expanding the use of digital assets in everyday spending and global commerce.Read All

Insignary has launched Clarity AIR, a source-code scanning product that identifies open-source code and AI-written code not declared in manifests, closing a blind spot in software security. Clarity AIR finds unknown open-source code, detects AI-written code, and inventories AI dependencies, producing audit-ready SBOMs and full reports.Read All

Why confirmation is not enough: a practical Human Firewall for testing beliefs, verifying identity, and using AI without locking onto one conclusion.Read All

Explore the reasons why we rewrote this popular version manager, why we focus on security, and why there are two builds.Read All

We learned how to moderate harmful content on social media, but generative AI is harder: individual prompts may look harmless while collectively contributing to malicious projects. As AI lowers the cost of cyberattacks and becomes more autonomous, the challenge is to detect intent in real time without limiting legitimate uses.Read All

Modern fraud relies on generative AI and synthetic identities designed to blend in seamlessly with legitimate traffic. To catch these sophisticated schemes, fraud prevention must evolve beyond single-transaction anomaly detection toward context-aware intelligence combining Graph Analytics, OSINT, and Human-in-the-Loop analysis.

Confirmed TLS tunnel from the prior tcpdump investigation gets the tshark treatment: filter, extract, and stats commands reveal the tunnel actually moved 117MB (not the originally estimated 84MB), almost all of it in a single 30-minute burst after 25+ hours of quiet beaconing — plus a real tooling gotcha (a misleading io,stat result) and the fix for it.Read All

Legacy code, memory leaks, and stolen session cookies expose the weaknesses of enterprise security gateways. Here’s why Zero Trust matters more than ever.Read All

Aembit, the identity control plane for AI agents, has announced support for securing personal agents’ access to enterprise environments, available immediately to existing customers at no additional cost. This solution addresses the risk of sensitive data exposure and unauthorized changes by combining the agent’s distinct identity with the identity of the employee it represents.Read All

Vibe coding may inadvertently ship vulnerabilities into production systems. Common vulnerabilities include hardcoded secrets and API keys, broken authorization, insecure defaults, and more. To address these issues, establish strict guardrails, integrate real-time security scanning, mandate human review for critical paths, and more.Read All

This article explores the history of cybersecurity through the Brain virus and Morris Worm, how attack methods have evolved, and why understanding security, ethics, and past attacks matters today.Read All

The OpenAI and Hugging Face incident is being discussed as an AI alignment story. It is just as much an identity and access story. The White House accord signed on September 29 asks frontier labs for internal controls, and every enterprise running AI agents should be building the same thing.Read All

Over the past two years, companies added AI agents fast and left security for later. Now many CTOs can’t say how many agents they have or what those agents can access. The risk isn’t only the AI model. It’s everything around it: prompts, tools, data, APIs, passwords and keys, and third-party connections. The fix starts with a simple step: make a full list of every AI agent, who owns it, and what it can touch. Think of it as an AI agent bill of materials. From there, test agents for prompt injection, check where credentials are stored, limit access, review vendors, and make sure logs show what each agent did. Repeat these checks whenever something changes.Read All

JinnPanel is a free, open-source web hosting control panel that aims to replace traditional panels like cPanel and Plesk. It is designed to be secure, scalable, and easy to use, with a focus on isolation and separation of concerns. JinnPanel uses a unique architecture that separates the web server from the privileged services, using a root worker to handle tasks that require elevated privilegesRead All

The concept of digital sovereignty is complex and cannot be reduced to a simple question of where data is stored, as it involves multiple layers of control, including infrastructure, software, and laws. The sovereignty gap arises when a country believes it has control over its digital infrastructure but actually has dependencies on foreign technologies, suppliers, or jurisdictions.Read All

Legit Security expanded its Agentic Remediation capability to cover vulnerabilities in open-source dependencies, enabling development teams to move from detection to a verified fix without manual triage. The expansion addresses a growing gap in application security, where traditional workflows can’t keep pace with the volume of vulnerabilities introduced through dependencies.Read All

Forensic watermarking embeds an invisible binary payload into video signals, allowing rights holders to track down stolen live feeds in seconds. This technology has become essential for major broadcasters, who use it to prevent piracy and protect their content.Read All

XSS can range from an informational finding to a critical security vulnerability, depending on several factors, including the security context in which the XSS executes, the type of application affected, and the application’s available functionality.Read All

The author built three tools: sBOMBox, sBOMBPath, and KeyScan, to address common security issues in Python projects, including vulnerable dependencies, exploitable vulnerabilities, and leaked secrets. These tools automate security checks and provide simple, consistent solutions to improve project security.Read All
