      <description>What draws me to each? For those interested in business, why you should also try out engineering For engineers, why business is also important Conclusion It seems pretty counterintuitive to talk about the junction of business and computer science. No two disciplines seem to be more at odds with each other than these two. As someone whose grown up interested in business and who has an older brother studying computer science, I&amp;rsquo;ve probably heard most common insults at least once at our dinner table.</description>

It was a pretty fun CTF although I wasn&amp;rsquo;t able to spend the full time focused on the competition. I&amp;rsquo;m just going to be writing about 2 of the Crypto challenges and the overall thought process when solving them.

      <description>Introduction to Marketing Advanced Marketing AP Economics Personal Finance Accounting Business Law Closing Thoughts Before I start, I wanted to mention how this is the 4th and last article I&amp;rsquo;m writing for Newport DECA. What started as a joke as to how I&amp;rsquo;d contribute to the DECA Debrief has become one of the many ways I&amp;rsquo;ve been able to share my passions in business with others (Credit to Songling for suggesting the great name &amp;ldquo;JC Hot Takes&amp;rdquo;).</description>

DECA Stock Market Personal Finance Internships Personal Projects Summer Programs School Courses Career Interviews Work Experience Conclusion For many interested, business as a field of study has some inexplicable draw to it. No matter what interests I pursue, what hobbies I partake in, business has always been a part of my life. I think that&amp;rsquo;s in part due to how society (at least in America) is, with its capitalistic nature.</description>

The Lay of the Land A Seemingly Green Light School Counselors Private Counselors (Paid) Author&amp;rsquo;s Note The Lay of the Land It’s hard to describe how much the landscape of college admissions has changed in the past 30 years.

      <description>Introduction December 1st 4 PM PST through December 3rd 5 PM PST. Those were the dates of our first cybersecurity competition.

Overall, this post hopes to discuss a bit of my thought process when making the various challenges, the things I&amp;rsquo;ve learned and finally end on a note of looking towards the future as a CTF player and a chall designer.</description>

Introduction Solving the Challenge Additional Thoughts Conclusion Introduction The hardest and also most interesting cryptography challenge of PicoCTF 2023 involved undoing AES using a side channel attack, specifically power analysis.
If I&amp;rsquo;m going to be honest, it was a pretty big surprise to see a side channel attack be the primary challenge within Pico but it was definitely a fun experience.
Solving the Challenge The core idea of correlation power analysis (CPA) is to take the non-linear part of AES, the S-box lookup and use that bit of info to extract more information about the key.</description>
