The Reverse Engineering Workflow
Tie the basics together into a repeatable methodology: how professionals move from an unknown binary to understood behavior, step by step.
The Reverse Engineering Workflow is a free Reverse Engineering & Binary Analysis Basics lesson on CoddyKit — lesson 4 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Reverse Engineering & Binary Analysis Basics learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
From Concepts to a Process
You know the concepts, ethics, and lab. Now you need a repeatable workflow so analysis is systematic, not random poking — it saves hours and produces real documentation.
Step 1: Define Your Goal
Start by defining your goal: Is this file malicious? How does the license check work? What protocol does it speak? A clear question keeps you out of the weeds.
Step 2: Triage the File
Next, triage the file for quick facts — its type, architecture, and obvious strings — before you commit to deep analysis.
file sample.bin
strings -n 6 sample.bin | head
sha256sum sample.binStep 3: Static Survey
Static analysis examines the binary without running it. Scan imports and strings for telltale API calls — networking, crypto, file I/O — to form hypotheses.
Step 4: Dynamic Confirmation
Dynamic analysis runs the binary in your isolated lab and watches behavior: files touched, registry keys, network calls. Static is the map; dynamic shows the roads driven.
Static vs Dynamic: Use Both
Use both: static gives full coverage but obfuscation hides intent, while dynamic shows real behavior but only executed paths. Pros iterate between them.
Step 5: Take Notes Constantly
RE is memory management for your brain — take structured notes on addresses, renamed functions, and confirmed facts. Your disassembler comments become a second memory.
## sample.bin notes
- 0x401000 main entry
- 0x4012a0 -> looks like decrypt_config (XOR loop)
- TODO: confirm C2 host stringIterate and Pivot
Findings reshape the plan: a network call sends you back to static, a found string sends you to dynamic. The workflow is a loop, not a straight line.
Scoping and Time-Boxing
Binaries are bottomless, so time-box each phase and stop once you've answered your goal. Log open questions for later instead of chasing every rabbit hole.
Reporting Your Findings
Analysis ends in a report: hashes and metadata for verification, key behaviors with evidence, indicators of compromise, and a confidence level per claim.
Staying Safe During the Workflow
Throughout, honor your lab rules: only analyze what you're authorized to, snapshot the VM before running anything, and keep malware network-isolated.

Recap
You've got a real methodology: define the goal, triage, survey statically, confirm dynamically, iterate, take notes, time-box, and report with confidence levels.
