Behind the Firewall ft. Stu Skove

by Morgan Prost / May 21, 2026

Sometimes the biggest threats are the ones you can't see. During a recent penetration test, Stu Skove uncovered a vulnerability that shows how a single unsanitized parameter can collapse the line between app security and full infrastructure compromise. At first glance, the app looked solid—no obvious issues. But deep in a file download workflow, two parameters were passing user input straight to the OS. The danger? It was blind. No errors,…

Don't just trust the tools. Sometimes, the best finds come from slowing down and asking, “what’s really happening here?” While reviewing how a web application responded to user input, KP’s Senior Penetration Tester, Brian Lowe, noticed something subtle… but it was just enough to warrant a closer look. Instead of relying only on automated tools, he crafted a custom payload by hand.  That extra step revealed a cross-site scripting (XSS) vulnerability…

In the worst-case scenario, if any user within the organization were compromised, all of this sensitive information could be leaked externally.

While performing network enumeration using a custom file share enumeration tool, he discovered several SMB shares that were accessible to all users without any restrictions. These shares contained over 30,000 files, the…

Audits are hard, but we make sure it's worth it. Not everyone loves audits, but the right experience can change everything.

Audits work best when there's transparency, not secrecy. During a recent engagement, Joseph encountered a situation that revealed much more than just a technical risk... a cultural one.  The client confirmed their penetration test was set for the weekend, but buried in the same email thread were plans to shut down vulnerable servers that Friday at 4:00p.m., then quietly bring them back on after the test.   The intent behind this wasn’t…
