• January 25, 2026Course 20 - Malware Analysis: Identifying and Defeating Code Obfuscation | Episode 1: Defeating Malware Obfuscation: Fundamentals, Impact

  In this lesson, you’ll learn about:
  

  • The Purpose of Code Obfuscation:
    • Defining obfuscation as the practice of intentionally making software difficult to read or analyze.
    • How malware authors use obfuscation to hide strings, functions, payloads, and command-and-control communication.
    • The concept of “raising the bar” for analysts by increasing the time and effort required to understand malicious intent.
    • Legitimate uses of obfuscation for protecting intellectual property in commercial software.
  • Obfuscation Across Programming Architectures:
    • The differences between native code (C, C++, Assembly) and interpreted or managed code (Java, .NET, Python).
    • Why native binaries are harder to analyze due to reliance on disassembly rather than source-like output.
    • How interpreted code can often be decompiled into structures that closely resemble the original source, making it generally easier to reverse.
  • Common Obfuscation Techniques:
    • Using meaningless variable and function names to disrupt manual analysis and signature-based detection.
    • Injecting junk code that adds complexity without affecting functionality.
    • Hiding indicators through string encoding or encryption that only resolves at runtime.
    • Manipulating control flow with misleading jumps and unreachable branches to confuse analysis tools.
  • Skills, Environments, and Tools for Deobfuscation:
    • The importance of understanding Assembly language, the Windows API, and the Portable Executable (PE) format.
    • Setting up safe analysis environments using Windows and Linux virtual machines, including REMnux.
    • Leveraging industry-standard tools such as IDA Pro, Ghidra, dnSpy, JD-GUI, and debuggers for static and dynamic analysis.

• January 22, 2026Course 19 - Ultimate Rust Crash Course | Episode 3: Rust Fundamentals: Mastering Ownership, References, and Borrowing

  In this lesson, you’ll learn about:
  

  • Ownership and Memory Management in Rust:
    • How Rust guarantees memory safety without a garbage collector.
    • The difference between stack and heap memory and how data lifecycles are managed.
  • The Mechanics of Ownership:
    • Rust’s three core ownership rules:
      • Every value has a single owner.
      • Only one owner exists at a time.
      • Values are dropped immediately when the owner goes out of scope.
    • The distinction between moving values (invalidating the original variable) and cloning values (performing a deep copy).
  • References and Borrowing:
    • Using references to access data without transferring ownership.
    • The role of lifetimes in ensuring references always point to valid data.
    • The borrowing rules: either one mutable reference or multiple immutable references, but never both at the same time.
    • How the dot operator automatically dereferences values for method access.
  • Practical Application (Exercise E):
    • Inspecting: Reading data using an immutable reference (&String).
    • Changing: Modifying data through a mutable reference (&mut String).
    • Eating: Passing ownership to a function, consuming the value and making it unavailable afterward.
  • Why These Rules Matter:
    • Preventing segmentation faults, data races, and dangling pointers.
    • Writing safer, more reliable code despite initial compiler challenges.

  • Project Organization and Reusability:
    • Moving logic into a library file (lib.rs).
    • Exposing functions with the pub keyword and importing them using use statements.
  • Control Flow and Program Logic:
    • Using if as an expression that returns a value, replacing traditional ternary operators.
    • Working with loops: loop (including labeled breaks), while, and for.
    • Iterating with ranges, both exclusive (0..50) and inclusive (0..=50).
  • Understanding Rust Strings:
    • Differences between borrowed string slices (&str) and owned, heap-allocated String types.
    • Why UTF-8 encoding prevents direct character indexing.
    • Safely accessing string data using iterators like .bytes(), .chars(), and .nth().
  • Practical Application:
    • Processing command-line arguments as vectors of strings.
