APIs have become one of the most important layers of modern software architecture. They connect web applications, mobile apps, SaaS platforms, identity providers, payment processors, cloud services, analytics systems, artificial intelligence tools, internal databases, and third-party integrations. For most organizations, APIs are no longer a secondary concern sitting behind the application. They are the application’s…

AI risk is often discussed like it is one massive category, but most organizations face a narrower and more practical set of problems: sensitive data entering tools that were never approved, AI features being added into business platforms without security review, employees relying on generated answers without validation, developers embedding models into workflows with weak…

A fragile detection rule is a rule that works only under narrow, ideal conditions. It may fire in a lab, catch one known proof-of-concept, or match a specific command from a public report, yet fail as soon as an attacker changes syntax, tooling, parent process, file path, argument order, encoding, log source, or execution method.…

AI-powered phishing is forcing security teams to rethink one of the oldest assumptions in email defense: that malicious messages usually look different from legitimate ones. For years, defenders trained users and tuned controls around obvious signs of fraud, including awkward grammar, misspelled domains, generic greetings, suspicious attachments, and low-quality branding. That model still catches plenty…

Today’s Topics: Congress Presses Instructure After Canvas Breach Congress is pressing Instructure for answers after the company’s Canvas learning management system was disrupted by a cyberattack that exposed user information, interrupted core school functions, and raised new questions about how well major education technology providers can contain repeat intrusions. The incident follows a pattern we…

Token replay is one of the reasons identity compromise has become harder for security teams to contain. In a traditional credential theft scenario, the attacker needs a password, a working MFA path, or some way to trigger a new authentication event. In a token replay scenario, the attacker steals an already-issued authentication or session artifact…

Microsoft’s May 2026 Patch Tuesday includes security updates for 120 vulnerabilities, with no zero-days disclosed this month. Despite the absence of actively exploited or publicly disclosed zero-days, the release is still significant due to the volume of high-severity flaws and the number of critical remote code execution vulnerabilities addressed. This month’s update includes 17 critical…

Today’s Topics: Ollama Vulnerabilities Expose Local AI Servers to Memory Leaks and Persistent Code Execution A newly disclosed Ollama vulnerability is drawing attention to a growing risk in local AI deployments: tools built to keep models and data off cloud infrastructure can still expose sensitive information when their APIs, model loaders, or update mechanisms are…

The recent Canvas security incident tied to ShinyHunters shows how quickly a third-party platform compromise can move from a vendor issue to an operational disruption for schools, universities, faculty, students, and IT teams. Instructure, the company behind Canvas LMS, confirmed that it detected unauthorized activity in Canvas on April 29, 2026. According to Instructure, the…

AI-generated code has moved from developer experiment to production reality, and security teams are now dealing with the result: faster software output, more code entering review, and a new class of AppSec risk where code can look clean, functional, and production-ready, yet still contain common security flaws. GitHub reported that nearly 80% of new developers…
