Crossing the other side of the bridge

Yesterday was the last day of the quarter. Naturally, it makes for a good day to reflect on the past three months. I mentioned in my last post that something new was on the horizon, and I’m now excited to share it. ORD -> SFO On March 1, 2019, I had my first one way flight booked from Chicago to San Francisco. I never actually thought I’d move further away from my friends and family. Today actually marks my first official month living in the city. But before I go any further, let’s address the elephant in the room.

It’s been about five years since my last update on this blog. I’ve been wanting to write for a while again, but life always seems to happen. Then time escapes.

A drive-by download that exploits CVE-2024-6332

First, Happy Thanksgiving to anyone that celebrates this holiday. In reality, I hope that we’re all thankful every day. Yes, I know- I’m working on a blog post on turkey day. It’s alright because I already helped cook a few items for the dinner table later this evening, and I have some free time, so why not? I’ll keep this one short.

You can learn more about it here.

I had a great time, and I met a few people that really made the rest of my time out there worthwhile. It has been a while since I last posted anything and thought I’d share some of the content that was presented during a basic malware analysis training session that I took at SecTor. You can find a better description of the session here.

Mcafee second-hand device research project

Earlier this year, I was invited to join a group of smart students from DePaul University to conduct some research on the risks associated with buying and selling used electronic equipment. Our research team received over fifty different second-hand devices that were purchased and provided by McAfee, part of Intel Security. For a short video and key findings, please visit the original blog post that was published by McAfee earlier last month.
