Malware Analysis
Malware Analysis & Reverse Engineering
Deconstruct the Threat. Engineer the Defence.
Malware analysis is no longer a niche discipline reserved for researchers in ivory towers. It is a critical operational requirement for the modern Blue Team.
In a landscape dominated by polymorphic ransomware and custom C2 frameworks, relying on automated sandbox reports is a liability. To truly defend the network, you must possess the capability to dissect the adversary's tooling, understand their logic, and turn their own code against them.

The Strategic Imperative
Why must a SOC Analyst or Incident Responder learn to reverse engineer?
Beyond the Sandbox: Automated sandboxes can be evaded. EDR can be bypassed. When the "Black Box" fails, manual analysis is the only path to ground truth.
Attribution & Intelligence: Understanding how a binary works reveals who built it. Code similarities track threat actors across campaigns.
Detection Engineering: You cannot detect what you do not understand. Analysis allows you to move from fragile hash-based blocking to robust behavioural detection and high-fidelity YARA rules.
Immediate Impact Assessment: During an active breach, waiting 48 hours for a vendor report is not an option. You need to know—right now—what the malware steals, who it talks to, and how it persists.
Core Competencies
Effective malware analysis requires a tiered skill set, moving from rapid triage to deep-dive disassembly.
1. Rapid Triage (The First Hour)
Skill: Quickly extracting IOCs (IPs, Domains, Hashes) without executing the file.
Objective: Immediate containment and blocking at the perimeter.
Techniques: String extraction, PE header analysis, entropy checking for packing.
2. Behavioural Analysis (Dynamic)
Skill: Monitoring malware execution in a controlled environment to map its lifecycle.
Objective: Understanding the "Kill Chain"—persistence mechanisms, lateral movement attempts, and C2 beacons.
Techniques: API hooking, process monitoring, traffic interception (PCAP).
3. Code Reversing (Static)
Skill: Reading Assembly (x86/x64) and decompiled C code to understand logic flow.
Objective: Defeating obfuscation, unpacking payloads, and finding hidden capabilities not triggered during dynamic analysis.
Techniques: Disassembly, control flow graph analysis, stack frame reconstruction.
4. Weaponisation (Detection)
Skill: Translating analysis findings into defensive signatures.
Objective: Immunising the network against the specific variant and its future iterations.
Techniques: Writing YARA rules, Sigma rules, and Suricata signatures.
Industry Standard Arsenal
We train on the tools used by elite threat intelligence teams and malware labs worldwide.

The heavy lifters. Used to turn binary code back into human-readable logic.
Debugging
x64dbg, WinDbg
Stepping through code execution instruction-by-instruction to bypass anti-analysis checks.
Triage & PE
PEStudio, Detect It Easy (DiE)
rapid assessment of file headers, imports, and compiler signatures.
Network

OSINT
VirusTotal, Any.Run
Correlating findings with global threat data.
Environment
FlareVM, REMnux
The standard Windows and Linux distributions for safe malware detonation.
From Binary to Defence
The ultimate goal of analysis is not a report—it is a stronger defence. RootGuard emphasises the operational loop:
Isolate the sample from the incident.
Dissect the sample to extract "Config" (C2 domains, encryption keys).
Develop a YARA rule based on unique code or string patterns.
Deploy the rule to hunt for other infections across the enterprise.
"To catch a predator, you must think like one. To stop a coder, you must read their code."
Strictly for educational and defensive research purposes. Never handle live malware on production networks.
