Packet Tracer Corpus Report — Phase 1 Ingestion & Telemetry

Generated by tools/phase1_inventory.py. Every sample is identified by SHA-256; header signatures are reported as observed raw bytes (no guessing).

1. Summary

Metric Value
Sample files discovered 69
Total corpus bytes 22,882,326 (21.82 MiB)
Distinct extension signatures 3
Distinct header/magic classes 2
Unreadable (I/O error) 31

2. Header / magic classification

Class Count Interpretation
opaque-encrypted 38 Modern container — outer scramble + AEAD; no readable prefix. PT 8/9 family.
unreadable 31 Host could not read the bytes (stale mount / I/O error). Excluded from hashing.

3. Extension breakdown

Extension Count
.pka 45
.pkt 19
.pkt.pka 5

4. Content de-duplication

Metric Value
Readable samples 38
Distinct payloads (unique SHA-256) 18
Digests appearing more than once 14

Corroboration is desirable for format coverage but not for file counts. Where the same payload exists under several directory trees it is listed once here.

5. Entropy distribution

Shannon entropy (first 64 KiB) Files
0.0 31
8.0 38

Entropy ≈ 7.8–8.0 on the whole file is the signature of the modern scramble+AEAD container (effectively random ciphertext). Entropy ≈ 6–7 with a readable prefix indicates the legacy zlib/qCompress container.

9. Storage telemetry — /mnt/oldpc (LUKS2 sdb3)

Recorded during Phase 1 because it directly bounds corpus coverage.

Fact Observation
Backing device sdb3 → oldpc_crypt (dm-2) → oldpc--vg-ubuntu--lv (dm-3), mounted read-only at /mnt/oldpc
LUKS LUKS2, aes-xts-plain64, 512-bit key, argon2id keyslot 0. Header clean. Provided passphrase verified valid (cryptsetup open --test-passphrase).
Unlock state Already unlocked; key resident in kernel keyring. Encryption is not the blocker.
SMART PASSED — drive self-assessment healthy
Filesystem ext4 damage: __ext4_get_inode_loc_noinmem: unable to read itable block, Can't read a block bitmap (debugfs will not open the FS)
Media Scattered unreadable sectors across the whole volume — alternating +/- regions in ddrescue mapfiles, ~4 bad areas per 64 MiB near the head
LVM lvs/pvs do not enumerate oldpc-vg; the LV is a stale manual mapping

Effect on corpus: 31 of 69 discovered files are unreadable. Of those, 9 are exact SHA-256 duplicates of files secured elsewhere, so the true loss is ~22 files: Documents/PT9-RE-*.pkt (reproducible from the in-tree generator), uwu.pkt, JSDF-AWACS*, and pt/saves/{AWACSJSDFPR7,AWACSJSDFPR7-BACKUP,ptalb}.pka.

Recovery status: deferred to the RECOVERY workstream (see ANALYSIS_PLAN.md §7). The modern container is fully deterministic (fixed key + fixed IV ⇒ file-independent keystream), which makes signature-free carving of the readable sectors feasible.

10. Locked artifact not yet opened

filedrop/uploads/icc2026.zip is a password-protected ZIP containing icc2026.pka (954,928 bytes). The LUKS passphrase does not open it (Bad password). Needs the correct archive password, or a ZipCrypto known-plaintext attack (bkcrack) if it is legacy PKWARE encryption rather than AES.
