The last missing data file. Seven known-bad-identity signatures over four
families - webshell, reverse_shell, cryptominer, hacktool - reproduced
verbatim from llm-security/knowledge/signatures.json at b0de0ca, key order
included. The file was generated from the parsed source rather than typed,
and provenance pins the source's byte length (2494) and SHA-256 so the
claim is checkable rather than asserted.
Note the family spellings: reverse_shell with an underscore, and
cryptominer rather than miner. The working note this file was planned from
had both wrong. They are policy keys - the engine filters on them and
interpolates them into every finding title - so a rename is a breaking
change, which is exactly why the table was read instead of recalled.
The rules were the easy half. The substance is engine_behaviour_not_data,
which draws the line between the table and the runtime around it. No rule
carries a flags field, because the engine compiles every pattern with `i`
unconditionally at signature-scanner.mjs:48 - so a consumer compiling these
case-sensitively silently under-matches all seven, and the dialect block
records that where a reader will hit it. Also engine, not data: matching
against five decode variants rather than raw bytes, the enabled-families
policy filter, per-file rule dedup, custom-rule merging, and a loader that
defaults four missing fields instead of rejecting a rule.
Two limits are stated as evidence limits rather than left implied. Seven
signatures are not malware coverage; a clean SIG result is not "no
malware", and the seed runtime's own header calls the table deliberately
tight. And three of the seven match on names - xmrig, mimikatz,
meterpreter - so a document discussing those tools matches. The seed
runtime hides that by excluding knowledge/, tests/, docs/ and
node_modules/, which is scan scoping and does not travel with the table.
Verified: 7/7 rule objects field-identical to source including key order,
no non-ASCII bytes, all seven compile in Node bare, i and iu (21/21) and in
Python re (7/7). Charter guard clean - no executable code in the repository.
README and CHANGELOG updated: the file moves out of "planned, not in
v0.1.0" and out of "not included".
