Introduction:
Malware analysis is the cornerstone of modern threat hunting and blue team defense, requiring a deep blend of static and dynamic reverse engineering skills. Blackstorm Security’s upcoming “Malware Analysis 1” training (next class 20/JUNE/2026) promises an intense, hands-on curriculum covering disassembly, debugging, and the notoriously challenging art of unpacking—preparing students for advanced professional techniques in Malware Analysis 2. This article extracts the core technical components from the course announcement and builds a practical guide with verified commands, tool configurations, and step‑by‑step methodologies for both Windows and Linux environments.
Learning Objectives:
– Master static malware analysis using IDA Pro, including navigation, cross‑references, and signature recognition.
– Perform dynamic analysis and debugging on packed or obfuscated binaries using x64dbg and GDB.
– Unpack real‑world malware samples through memory dumping and import address table (IAT) reconstruction techniques.
You Should Know:
1. Foundations of Malware Analysis – Static vs. Dynamic Workflows
Every analysis starts with a triage phase. Static analysis examines the binary without executing it, while dynamic analysis observes behavior in a sandbox. Blackstorm’s course emphasizes both, with a solid foundation for unpacking – a critical skill because most malware today uses packers (UPX, ASPack, VMProtect) to evade signature detection.
Step‑by‑step static triage (Linux):
Identify file type and architecture file suspicious_sample.exe Extract readable strings (minimum length 6) strings -1 6 suspicious_sample.exe | head -50 Check for packers using a signature scanner python3 /usr/share/pev/peid.py suspicious_sample.exe or use 'detect-it-easy' View PE headers objdump -x suspicious_sample.exe | grep -i "section"
Step‑by‑step dynamic monitoring (Windows):
Open an isolated VM (e.g., Windows 10 sandbox). Run these commands as administrator before executing the sample:
:: Monitor process creation and network connections tasklist /v > before.txt netstat -anob > net_before.txt :: Start Process Monitor (procmon) – filter on process name later :: Capture registry and file activity with Regshot (take first snapshot) :: Execute the sample (isolated) malware.exe :: After execution, take second Regshot snapshot and compare :: Then dump active processes: tasklist /v > after.txt fc before.txt after.txt
This two‑pronged approach reveals initial indicators like dropped files, persisted registry keys (e.g., Run, RunOnce), and outbound beaconing.
2. Mastering IDA Pro for Static Analysis – What to Look For
IDA Pro is the industry standard for disassembly. The Blackstorm course explains exactly what to search for in a malicious binary – a crucial differentiator. Instead of aimlessly browsing, you focus on imports, entry point anomalies, and control flow graphs (CFGs).
Step‑by‑step IDA Pro workflow:
– Load the binary (PE, ELF, or Mach‑O). Select “Portable executable for 80386” (or appropriate).
– View the entry point (usually `start` or `main`). Press `Space` to switch to graph view.
– Analyze imports: Open Imports tab (`Ctrl+Shift+I`). Malicious imports include:
– Network: `WinHttpOpen`, `URLDownloadToFile`, `socket`
– Process injection: `VirtualAllocEx`, `WriteProcessMemory`, `CreateRemoteThread`
– Persistence: `RegCreateKeyEx`, `RegSetValueEx`
– Locate interesting strings (`Shift+F12`). Right‑click any string → “Cross reference to” (`X`) → jump to code referencing it.
– Use the decompiler (Hex‑Rays): Click on a suspicious function and press `F5` to generate pseudo‑C code. Look for loops that decode buffers or call `memcpy` into allocated memory – signs of unpacking stubs.
To automate basic static checks on Linux (headless IDA alternative):
Use radare2 to list imports r2 -qc "is" suspicious_sample.exe Use Ghidra’s headless analyzer analyzeHeadless /tmp/malware_project -import suspicious_sample.exe -postScript AnalyzeAllHeadless.java
The course stresses that unpacking often begins with identifying the Original Entry Point (OEP) after the unpacker runs. In IDA, if the binary is packed, you’ll see few imports and a single ambiguous section with execute permissions. That’s your cue to switch to dynamic debugging.
3. Debugging and Unpacking – Step‑by‑Step with x64dbg and GDB
Unpacking is the most challenging part of malware analysis, according to the course. The technique involves running the malware in a debugger, letting the unpacker decompress the original binary in memory, then dumping the unmapped executable and reconstructing its imports.
Step‑by‑step unpacking on Windows with x64dbg:
1. Load the packed binary into x64dbg. Set a breakpoint on `VirtualProtect` or `VirtualAlloc` (common unpacker APIs).
2. Run (F9) until you hit the first breakpoint. The unpacker will allocate memory with `PAGE_EXECUTE_READWRITE`.
3. Watch for `memcpy` or `rep movs` instructions – these copy the unpacked payload to the new region.
4. Find the OEP: After the last copy, the unpacker jumps (`jmp` or `call`) to the OEP. Common OEP signatures:
– `push ebp; mov ebp, esp` (standard function prologue)
– `push 0x12345678; push 0x87654321` (push of immediate values, typical of compiled C/C++).
5. Once at OEP, dump the memory region: `Plugins → Scylla → Find OEP → Dump → Fix IAT`. Scylla reconstructs the import table.
6. Save the unpacked binary and rescan with IDA Pro – now imports and strings will appear.
Linux equivalent (using GDB for ELF packers like UPX):
Install UPX to pack/unpack (for learning) sudo apt install upx Pack a legitimate binary upx -o packed_bin original_bin Debug with GDB gdb packed_bin (gdb) break _start (gdb) run (gdb) info registers note ESP, EIP (gdb) stepi single‑step until you see a far jump (jmp) (gdb) x/10i $eip examine instructions; look for OEP pattern (gdb) dump memory dumped.bin 0x00400000 0x004ff000 adjust addresses Then use 'file' and 'strings' on dumped.bin to verify.
The Blackstorm course provides real‑world samples where packers are custom‑written, requiring deeper breakpoint analysis on hardware access (`DR0`‑`DR3`) and anti‑debugging bypasses – topics covered in the advanced modules.
4. Practical Unpacking Automation & Tool Configuration
For analysts handling many samples, manual unpacking is time‑consuming. The course teaches how to configure debuggers to script unpacking routines. Use x64dbg’s Python scripting (via the `x64dbgpy` plugin) or WinAppDbg.
Example x64dbg script (pseudo‑Python):
Set breakpoint on kernel32!VirtualAlloc
dbg.set_breakpoint("kernel32.VirtualAlloc", callback=on_virtual_alloc)
def on_virtual_alloc(debugger, address, size, allocation_type, protect):
if protect & 0x40: PAGE_EXECUTE_READWRITE
debugger.log("Potential unpacking allocation at " + hex(address))
Set memory breakpoint on that region to catch write
debugger.set_memory_breakpoint(address, size, BREAK_ON_WRITE)
Windows command line configuration for a safe sandbox:
:: Disable Windows Defender real‑time protection (temporarily in VM) Set-MpPreference -DisableRealtimeMonitoring $true :: Enable PowerShell script execution for automation Set-ExecutionPolicy Unrestricted -Scope Process :: Use FlareVM (FireEye’s toolset) – preconfigured with IDA, x64dbb, ProcMon :: Install via: https://github.com/mandiant/flare-vm
5. Real‑World Threat Hunting & Blue Team Integration
After mastering unpacking, analysts join the blue team by writing detection rules. The course prepares students for Malware Analysis 2, which covers professional techniques like YARA rule creation and memory forensics.
Step‑by‑step YARA rule from unpacked strings:
rule Suspicious_Beacon_APIs {
meta:
description = "Detects unpacked malware using WinHTTP"
strings:
$a = "WinHttpOpen" wide ascii
$b = "WinHttpConnect" wide ascii
$c = "POST /beacon" fullword ascii
condition:
all of ($a,$b) or $c
}
Use it to scan your environment:
Linux yara64 -r rule.yara /path/to/suspicious/directory Windows (with YARA installed) yara64.exe -r rule.yara C:\Samples\
Additionally, the course teaches how to integrate IDA Pro analysis with Ghidra for collaborative reverse engineering. For cloud‑hardening contexts, you can apply the same unpacking skills to container escape malware or server‑side ELF binaries.
6. Post‑Training Continuous Learning – The Blackstorm Kit
The physical kit (customized box, printed certificate, t‑shirt, bookmark, folder) underscores the instructor’s commitment to real instruction time – every hour is actual teaching, not labs. After training, students receive post‑course doubt clarification. To keep skills sharp, practice on platforms like:
– MalwareBazaar (abuse.ch) – download live samples
– VX Underground – unpacking challenges
– OALABS (YouTube) – step‑by‑step unpacking tutorials
Recommended weekly lab: unpack one new sample, write a YARA rule, and simulate detection in a SIEM (e.g., Splunk free tier).
What Undercode Say:
– Key Takeaway 1: Blackstorm’s “Malware Analysis 1” prioritizes real instruction hours, not filler – every minute is used for concepts, debugging, and hands‑on unpacking with IDA Pro, filling a critical gap in most cybersecurity courses.
– Key Takeaway 2: The physical kit (printed material, certificate, swag) reflects a professional touch, but the real value lies in the practical, updated challenges that prepare students for advanced Malware Analysis 2 – especially important for blue teamers fighting polymorphic threats.
Analysis for around 10 lines: Alexandre Borges, a respected iOS/Chrome/Android exploit developer, endorses this training, lending credibility. The emphasis on unpacking as a “challenging” core skill is spot‑on – most entry‑level analysts stop at static scanning. By detailing static (IDA Pro) and dynamic (debugging) workflows, the course bridges the theory‑practice gap. The post‑training support and constant content updates ensure relevance against evolving packers (e.g., VMProtect 3.x). However, the lack of pricing or direct URL in the announcement means interested students must proactively visit the Blackstorm Security website or email the banner address – a minor friction point. Overall, this is a high‑value, technical deep dive for mid‑level threat hunters.
