Episode 114: Threats and Vulnerabilities — Zero-Day, SQLi, XSS

This episode explains the technical underpinnings of some of the most dangerous threats and vulnerabilities in modern systems. We start with zero-day exploits, where attackers take advantage of unknown software flaws before patches can be released. These are especially damaging because traditional defenses often can’t detect them. Next, we explore structured query language injection—SQLi—an attack that targets poorly secured databases.We also explain cross-site scripting, or XSS, which allows attackers to inject scripts into web pages viewed by others. These vulnerabilities are tested on the A Plus exam in the context of prevention, detection, and appropriate response. Understanding how they function and where they appear helps you recognize risks in both exam questions and real-world systems. Brought to you by BareMetalCyber.com.
