Welcome to the KevinSec Blog.
This section contains practical notes, technical breakdowns, lessons learned, and field observations from offensive security work.
A practical mindset guide for ethical hackers, pentesters, and security researchers who want to move beyond tools and think in systems.
BOLA happens when an API exposes object identifiers but fails to verify whether the caller is allowed to access the object.
API broken authentication appears when an API cannot reliably prove who the caller is or cannot safely manage credentials, tokens, and sessions.
Burp Suite is most effective when used as a structured manual testing workspace, not just as an intercepting proxy.
CORS is a browser security control for controlled cross-origin access. Misconfiguration can expose sensitive data to untrusted origins.
Credential phishing targets passwords, sessions, and MFA workflows. Employees can reduce risk by verifying login prompts, using password managers, enabling MFA, and reporting fast.
CVSS helps standardize vulnerability severity, but pentesters still need to explain exploitability, context, and business impact.
File upload features are high-risk because they accept complex user-controlled content and often interact with storage, parsing, and public access paths.
A safe phishing simulation program should measure risk, teach behavior, protect employees, and avoid collecting real credentials or creating unnecessary harm.
Suspicious emails can look professional. This guide shows how to inspect context, sender, links, attachments, tone, and requested actions safely.
