Cybersecurity What is Privilege Escalation? How Attackers Go From Foothold to Full Control An attacker starts with a low-privileged shell or user account and escalates to root or Administrator using misconfigurations, SUID binaries, kernel exploits, and Active Directory attacks. Here's every technique, the tools professionals use, and how to harden against it.
Cybersecurity What is Social Engineering? The Attacks That Bypass Every Technical Control Phishing, vishing, pretexting, physical infiltration — here's how every technique works, how attackers use them in production breaches, and how to actually defend against them.
Cybersecurity What is Penetration Testing? The Discipline of Breaking Things Before Attackers Do Penetration testing is authorized, structured hacking — finding vulnerabilities in systems, networks, and applications before real attackers do. Here's the full methodology, every phase of a real engagement, the tools professionals use, and how to build a career in it.
Cybersecurity What is Cross-Site Scripting (XSS)? The Attack That Turns Your Website Against Your Users XSS injects malicious JavaScript into web pages served to other users — stealing sessions, redirecting to phishing pages, or silently exfiltrating data. It's been in the OWASP Top 10 since 2003. Here's every type, how each one works, and how to actually fix them.
Cybersecurity What is SQL Injection? The Attack That's Been Destroying Databases Since 1998 In 2008, attackers used SQL injection to breach Heartland Payment Systems, a payment processing company. They stole 130 million credit and debit card numbers. The breach cost Heartland over $140 million in settlements and fines. The CEO described it as an "international cybercrime ring." The technical execution was
Cybersecurity What is Encryption? The Math That Keeps Your Data Private Encryption transforms readable data into unreadable ciphertext that only someone with the right key can reverse. It's what makes HTTPS, messaging apps, banking, and password storage work. Here's how it actually functions.
Cybersecurity What is Cybersecurity? The Field That Keeps the Internet From Collapsing Cybersecurity is the discipline of protecting systems, networks, and data from attack, damage, and unauthorized access. Here's what it actually covers, how attacks work, how defense works, and why every developer needs to understand it.
Cybersecurity Understanding Why PassKeys will Replace Passwords First, allow me to start off with that I am absolutely loving using Passkeys to login into CloudFlare, Stripe, and other important services that I use to run CoderOasis. This should of been a thing a few years ago – maybe all the way back in 2016 or so. The growth
Cybersecurity Hacktivism: Social Justice by Data Leaks and Defacements Around the end of February, a hacktivist that calls himself JaXpArO and My Little Anonymous Revival Project breached the far-right social media platform named Gab. They managed to gain seventy gigabytes of data from the backend databases. The data contained user profiles, private posts, chat messages, and more – a lot
