Lyrics

[Verse 1]
When the kernel sleeps in storage space
We can peek inside without a trace
No runtime needed, no system load
Just static tools to crack the code
objdump and nm are our best friends
To see how kernel magic blends

[Chorus]
objdump dash d for disassembly
nm for symbols, clear to see
Static analysis, safe and sound
No execution, knowledge found
Read the sections, map the flow
Everything you need to know

[Verse 2]
Symbol tables tell the story true
Functions, variables in clear view
nm dash D shows dynamic links
While nm dash g finds global thinks
Text and data sections laid out clean
The clearest kernel map you've seen

[Chorus]
objdump dash d for disassembly
nm for symbols, clear to see
Static analysis, safe and sound
No execution, knowledge found
Read the sections, map the flow
Everything you need to know

[Bridge]
Dash t for symbol types displayed
Dash s shows sections neatly laid
Cross-reference calls with dash x
Find dependencies, no complex hex
From entry points to exit calls
Static view reveals it all

[Verse 3]
Architecture matters, choose your flags
ARM or x86, avoid the snags
objdump dash S mixes source with code
Making sense of the kernel's load
Security analysis starts right here
With static tools, the path is clear

[Chorus]
objdump dash d for disassembly
nm for symbols, clear to see
Static analysis, safe and sound
No execution, knowledge found
Read the sections, map the flow
Everything you need to know

[Outro]
Before you boot, before you run
Static analysis gets things done
Kernel secrets, plain to see
With objdump and nm mastery
