SCI reduces the chances of an e-commerce skimming attack through the inspection of a website’s shopping cart by a SecurityMetrics Forensic Investigator.Read All

SpyCloud released its report,  The Identity Security Reckoning: 2025 Lessons, 2026 Predictions. The report outlines 10 of the top trends that will shape the cyber threat landscape in the coming year.Read All

The GTG-1002 is widely assessed as the first large-scale cyber attack executed with near complete AI autonomy. It simultaneously managed intrusion campaigns against about 30 different organizations at once including major tech, financial firms, chemical manufacturers, government agencies. The sophistication was entirely in the orchestration, not the individual tools.Read All

On November 3, 2025, Balancer lost over $120 million in one of the largest DeFi breaches of the year. Attackers exploited a rounding direction error that had existed in the code for years. Users could only watch as their funds drained or race each other to the exit.Read All

78% of organizations run AI in production. Half have no AI-specific security. The damage is measurable: a $25M deepfake wire transfer, Samsung’s leaked source code, and Microsoft Copilot data breaches. This article is a playbook for leaders and practitioners who want both speed and safety.Read All

AI agents aren’t just tools anymore—they think, plan, and act on their own. That changes everything about enterprise security. It’s time to stop guarding networks and start securing intent.Read All

A Twitter user tweeted a screenshot of an email from customer support for Obsidian Entertainment. The bot told them to email their account credentials and verification document to the dedicated support and pointed to wrong email address. This is not only a security nightmare but also an architectural mishap. The failure is a preview of what happens across every industry when organizations bolt AI onto existing systems.Read All

93% of security leaders say insider threats are as difficult or harder to detect than external cyberattacks. Only 23% express strong confidence in stopping them before serious damage occurs. Report warns that most organizations remain reactive despite a surge in AI-driven risks and increasing prevalence of decentralized workforces.Read All

Data Security has long been the cornerstone of enterprise cybersecurity strategies. But as artificial intelligence becomes deeply embedded in business operations, a new discipline emerges: AI Security.Read All

npm’s new token lifetime limits (90-day max, 7-day default) and mandatory WebAuthn are good security hygiene, but they don’t address how attacks actually happen. The September 2025 breach that compromised 18 packages with 2.6B weekly downloads succeeded via phishing—the attacker had full account access and could generate tokens at will. The XZ Utils backdoor involved three years of social engineering to gain maintainer trust. Token rotation doesn’t stop account takeovers, malicious insiders, or the lack of code review. npm is treating the symptom (token exposure) rather than the disease (anyone can publish anything instantly).Read All

Healthcare is experiencing an unprecedented explosion in connected medical devices. From smartwatches monitoring heart rhythms to continuous glucose monitors transmitting blood sugar levels, patients and providers have embraced the Internet of Medical Things. While these innovations have revolutionized patient care and improved outcomes, they have created a massive, largely invisible security vulnerability.Read All

AI coding tools promise velocity but deliver chaos: security holes, context loss, infinite debugging loops. I spent 8 months solving this and created DevFlow a pure prompt engineering framework that adds discipline to AI development. Nine specialized agents handle everything from architecture to security reviews. Five workflow types route tasks intelligently. Quality gates prevent incomplete work. Works with Claude Code, Cursor, Gemini, or any AI assistant. The result? Production-ready code with full audit trails.Read All
