What healthtech AppSec needs beyond generic security practices
242.9 million records were exposed in 2024 HIPAA breaches. Generic AppSec checklists don't satisfy FDA premarket SBOM rules or a pending HIPAA rewrite.
JWT security vulnerabilities and best practices
The jsonwebtoken library shipped three separate signature-bypass CVEs between 2015 and 2022 — algorithm confusion is still the most common way JWTs fail.
Securing gRPC APIs: mTLS, Interceptors, and Input Validation
CVE-2023-44487 knocked grpc-go services offline with a Rapid Reset flood — a reminder that gRPC ships fast, insecure by default, and needs hardening at every layer.
Where should your SPA store auth tokens?
OWASP has warned against localStorage tokens for years, yet it remains the default in countless SPA tutorials — one XSS bug is all it takes to exfiltrate every session.
Symbolic Reasoning vs. LLMs: Which Static Analysis Actually Finds Bugs?
The CASTLE benchmark tested 13 static analyzers and 10 LLMs on 250 programs — neither approach won outright, and the reasons why matter for your AppSec stack.
Dynamic Scanning, Explained for Engineers Who Aren't Security Specialists
Dynamic scanning tests a running application the way an attacker would, by sending it requests and watching what comes back. Here's what that actually involves and when it's the right tool.
AI-driven DAST for modern applications
73% of open-source developers now use AI coding tools. Dynamic testing built for nightly crawls can't keep pace with apps that reshape their attack surface daily.
CVE-2025-29927: inside the Next.js middleware auth bypass
A single spoofed header let attackers skip Next.js middleware entirely — CVSS 9.1, four major versions affected, exploited in the wild within days.
A HIPAA technical safeguards checklist for application security teams
HHS reported 663 large healthcare breaches in 2024 exposing 242.9M records. Here's how §164.312's technical safeguards map to concrete app-sec controls.

A CVSS 10.0 pre-auth RCE in React Server Components, exploited within 48 hours of disclosure — how the deserialization flaw works and how to mitigate it.
Reducing false positives in SAST and SCA tools
NIST benchmark data puts some SAST false-positive rates near 78%. Reachability analysis and contextual triage are how teams cut that noise without missing real risk.
A methodology for testing SPAs for client-side vulnerabilities
DOM XSS, token storage, and API exposure don't show up in a server-side scan — here's a repeatable methodology for testing React, Vue, and Angular apps.
