xdumpgo dump --pid <PID> --output dump.bin
xdumpgo dump --pid 1337 --hash-algo sha256 --hash-file hashes.txt After the dump, run:
| Symptom | Cause | Solution | |---------|-------|----------| | Dump is smaller than expected | Ran out of memory or disk | --page-buffer-size 64 (increase buffer) | | Checksum errors on every page | Process changed during dump | Add --frozen-vm and --freeze-attempts 3 | | Missing regions | Permission denied | Run as root: sudo xdumpgo ... | | Dump contains uninitialized data | Reading from /dev/mem directly | Use --pid instead of --mem-range | For repeatable, high-quality dumps, script the process. xdumpgo tutorial extra quality
sudo xdumpgo info --dump $OUTPUT_DIR/full.bin --verbose > $OUTPUT_DIR/metadata.txt
xdumpgo dump --pid 1337 --output proc_dump.bin --verify-checksums --skip-bad-pages --page-size 4096 This produces a raw binary image of the process's memory space, skipping only the truly unreadable pages. The "extra quality" keyword implies moving beyond defaults. Use these four advanced switches: 2.1 Atomic Snapshots with --frozen-vm Standard dumps change while you read them (the "moving target" problem). Enable OS-level process freezing: xdumpgo dump --pid <PID> --output dump
In the world of digital forensics, penetration testing, and low-level system debugging, the tools you use determine the quality of the data you retrieve. Enter xdumpgo —a powerful, high-performance utility designed for extracting memory regions, process dumps, and raw binary data from running systems. But simply running the command isn't enough. To achieve what experts call "extra quality" —dumps that are forensically sound, complete, and uncorrupted—you need a structured approach.
| Flag | Purpose | |------|---------| | --verify-checksums | Validate each page read | | --skip-bad-pages | Log errors but don't abort | | --page-size 4096 | Match system page size (default 4KB) | The "extra quality" keyword implies moving beyond defaults
