Create realistic memory dump and hexdump output for debugging and forensics training. Simulate memory analysis with address ranges, hex bytes, and ASCII columns.
Press Ctrl + C to exit. Output is simulated for demo purposes only.
This module simulates memory addresses, hex bytes, and region patterns log events with realistic pacing.
It is designed for demos, log pipeline testing, and documentation where the real stack is unavailable.
All output is generated locally in the browser and is safe to run.

No. It is a simulator that prints log text only.
Yes. The CLI supports speed and repeat options, and the web page can be refreshed.
No. It does not install, update, or modify anything.
Memory dump and hex dump tools output address ranges, hex bytes, and ASCII columns. They are used in forensics and low-level debugging.
The simulator above produces that style for safe demos and log pipeline testing.
Popular questions and answers from Stack Overflow related to memdump.
Use hexdump -C file for hex+ASCII view, xxd file for hex dump, or objdump -s for object files. For crash dumps, use tools like WinDbg (Windows) or crash (Linux).
0xCD = uninitialized heap memory (MSVC). 0xDD = freed heap memory. 0xFD = guard bytes. 0xCC = uninitialized stack. These patterns help identify memory issues during debugging.
Linux: gcore PID creates core.PID file. Or /proc/PID/mem with root. Windows: Task Manager > Create dump file, or procdump -ma PID. Dumps can be large.
Use gdb: gdb ./program corefile. Commands: bt (backtrace), info registers, x/100x $rsp (examine memory). Load symbols with symbol-file. Requires debug symbols (-g).
hexdump -C for hex+ASCII. strings command extracts printable strings. od (octal dump) with various formats. xxd -r reverses hex to binary. Use objdump for structured binary.
Core dump: full process memory including stack, heap, code, registers. Heap dump: only dynamically allocated memory (Java heap, malloc). Heap dumps are smaller, focused on application data.
Set ulimit -c unlimited for unlimited size. Configure /proc/sys/kernel/core_pattern for location/naming. Example: echo "/tmp/core.%e.%p" > /proc/sys/kernel/core_pattern.
Use strings command: strings dumpfile | grep pattern. For binary patterns: grep -obUaP "\x00\x01\x02" file. xxd + grep for hex patterns. Consider volatility for forensics.
In gdb: dump memory filename start_addr end_addr. Linux: dd if=/proc/PID/mem bs=1 skip=$ADDR count=$SIZE. Use readelf to find section addresses.
Volatility Framework: most popular, plugins for various OS. Rekall: similar to Volatility. LiME: Linux memory acquisition. WinDbg: Windows analysis. Autopsy: general forensics with memory plugins.
