Some of the most actionable threat intelligence is found behind closed doors. In this episode, we examine closed source threat intel—feeds and services provided by vendors, threat intelligence platforms, and information-sharing communities like ISACs. These sources offer high-fidelity, curated intelligence that often includes proprietary data, malware signatures, actor profiles, and zero-day warni...

Not all threat intelligence comes with a price tag. In this episode, we explore the value and limitations of open source intelligence (OSINT) in cybersecurity operations. You’ll learn how analysts use publicly available sources such as social media feeds, blogs, government advisories, and dark web monitoring platforms to gather early indicators of compromise and attacker activity. These sources ar...

All threat intelligence is not created equal. In this episode, we explore how analysts evaluate the reliability of threat intelligence based on confidence levels—specifically timeliness, relevancy, and accuracy. We also break down how to assess threat feeds and indicators in context, helping you understand when to trust data and when to investigate further. We then introduce the concept of tactics...

Some of the most damaging threats come from within—or through trusted partners. In this episode, we explore the two primary forms of insider threats: intentional actors who sabotage or steal for personal gain, and unintentional insiders whose negligence leads to exposure. You’ll learn the warning signs, the types of data most often targeted, and how security teams detect and investigate these risk...

Understanding the adversary is the first step to anticipating their next move. In this episode, we profile the major categories of threat actors you need to know for the CySA+ exam: advanced persistent threats (APTs), hacktivists, organized crime groups, nation-state actors, insider threats, and even low-skill opportunists known as “script kiddies.” You’ll hear how motivations, tactics, and resour...

Not all threats require a human response—and not all analysis can scale without scripting. In this episode, we dive into the scripting and automation fundamentals analysts need to understand for CySA+ and real-world workflows. You’ll learn how JSON and XML are used to structure data across APIs and security platforms, how PowerShell and shell scripts are used in detection and attack simulation, an...

Attackers often succeed not because they're invisible, but because they mimic normal user behavior—until they don’t. In this episode, we explore how user and entity behavior analytics (UEBA) help security analysts detect when users start acting outside of their established patterns. You’ll learn about common indicators of abnormal behavior such as impossible travel, login attempts from unexpected...

When a file changes unexpectedly, something important may have happened—and hashing is one of the best tools we have to track it. In this episode, we explain how file hashing works, which algorithms are most commonly used (like SHA-256), and how analysts use hashes to verify file integrity, detect tampering, and cross-reference files with malware databases. You’ll also learn how to generate hashes...

Phishing remains one of the most common and effective attack vectors—and analysts are often the last line of defense.
