IDA Binja Named
IDA Pro and Binary Ninja are named commercial disassemblers — know they exist, use legally licensed copies on $RE_LAB only.
Visual · re_ida_binja_named
IDA/Binary Ninja named literacy. $RE_LAB only. Original Cyberlium.
Opening
IDA and Binary Ninja are industry tools — naming them is literacy, not a license to pirate the tools or targets.
IDA Pro (Hex-Rays decompiler) and Binary Ninja are commercial disassemblers/decompilers widely used in industry and CTF. Both offer graph views, scripting, and type systems similar to Ghidra. Cyberlium names them so you recognize job postings and writeups — use only properly licensed installs on $RE_LAB for authorized binaries. You will NOT pirate IDA/Binary Ninja licenses or use them to crack commercial software. Ghidra remains the free default for labs. Next: Static Tools Lab.
1. IDA Pro (named)
Interactive Disassembler with graph mode, Hex-Rays decompiler plugin, IDC/Python scripting. Industry standard for firmware and malware RE — when authorization and license exist.
On $RE_LAB: if your school provides licensed IDA, use only on crackmes and toys per policy — same ethics as Ghidra.
Command guide
Try these commands — IDA Pro (named)
═══ LINUX / macOS (Malware Static & Dynamic Triage) ═══
Inspect PE / ELF binary headers and sections
Command — copy this
readelf -h sample.bin 2>/dev/null || xxd -g 1 -l 32 sample.bin
Check binary entropy (high entropy often signals packed or encrypted payloads)
Command — copy this
python3 -c "
import math, sys
data = open('sample.bin', 'rb').read() if len(sys.argv) > 1 else b'MZX\x00\x90'
ent = -sum((data.count(bytes([b]))/len(data))*math.log2(data.count(bytes([b]))/len(data)) for b in set(data))
print(f'Calculated File Entropy: {ent:.4f} (Entropy > 7.0 suggests packed/encrypted)')
" sample.bin 2>/dev/nullPrimary tools to practice this lesson: curl, strings. Reference sites: IDA docs (https://docs.hex-rays.com/); Binary Ninja docs (https://docs.binary.ninja/); strings(1) (https://man7.org/linux/man-pages/man1/strings.1.html). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Binary Ninja (named)
Modern UI with IL lifts, MLIL/HLIL intermediate languages, collaborative projects. Strong API for automation on authorized targets.
Compare workflow to Ghidra: import → analyze → rename → decompile — tool differs, literacy transfers.
3. Tool licensing ethics
Forbidden: pirating IDA/Binary Ninja, using cracked disassembler installs to crack other commercial software, or analyzing unauthorized binaries because 'the tool is expensive so I pirated it.'
Ship: comparison table — Ghidra vs IDA vs Binary Ninja, one column each: cost model, decompiler, script language. Next: Static Tools Lab.
4. What you ship: disassembler comparison table
Ghidra/IDA/Binary Ninja comparison. $RE_LAB licensed use only. NEVER tool or target piracy. chmod 600.
5. What you record before the next lesson
Date. Disassembler comparison. $RE_LAB named. File t23-m05-l03-ida-binja-named.txt chmod 600.
6. Wrong vs right: commercial piracy vs crackmes/CTF toys
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Pirate IDA to crack games. Confuse tool literacy with license to bypass DRM.
Right
Write disassembler comparison with licensing ethics note. Next: Static Tools Lab.
Mission: compare three disassemblers
1) Three columns: Ghidra, IDA, Binary Ninja. 2) Note cost and script language each. 3) Write NEVER pirate tools line. 4) chmod 600.
