CyberSecurityUPandClaude Opus 4.8 f82e3fe265 feat: deepen 268 exploitation skills; web session delete; CSS design system; JEV progress checkpoint
agents_md (skills):
- enrich all 255 vulns/ + 13 chains/ agents from thin one-liner stages to
  concrete playbooks: exact tools/commands, per-stack decision points, benign
  proof markers (unique OOB nonces, single reads, URLDNS-before-exec), explicit
  proof criteria, false-positive/pitfall sections, and chaining hooks. Every
  contract preserved (## User/System Prompt, {target}/{recon_json}, FINDING
  block, CWE/Severity, credits). avg 37->53 lines; loader parses all 449.

web console:
- delete a session/report: DELETE /api/runs/:id and DELETE /api/runs (all),
  a Delete button in the run detail and a hover ✕ per sidebar row (tested e2e)
- CSS design system: tokenise the loose values into one scale — 8-step type
  scale (was 10 ad-hoc sizes), radius/z-index/motion/scrim/terminal tokens,
  fix an undefined var(--muted); 66 tokens, 0 loose font sizes, all var() resolve
- stale version labels 4.0.0/4.2.0 -> 4.2.1

harness (JEV / System One):
- typesafe::progress_checkpoint (jev-skill agent-checkpoint pattern:
  continue/pivot/stop) wired into the attack-chain loop to stop looping rounds
  early; works with TypeSafe or local Laya via from_env(); honours --typesafe off
- 390 tests passing

# Typosquatting Detection Specialist Agent
## User Prompt
You are testing **{target}** for Typosquatted dependency risk in the target's stack (a malicious lookalike actually referenced/installed).
**Recon Context:**
{recon_json}
**METHODOLOGY — this is a WHITEBOX/manifest review: cite the exact manifest + line and the registry evidence. No live network exploitation claims.**
### 1. Enumerate declared and locked dependencies
- npm: `package.json` deps/devDeps + `package-lock.json`/`yarn.lock`/`pnpm-lock.yaml` (resolved names, versions, `resolved`/`integrity` URLs).
- Python: `requirements.txt`, `pyproject.toml`/`poetry.lock`, `Pipfile.lock`.
- PHP: `composer.json` + `composer.lock`. Ruby: `Gemfile.lock`. Go: `go.mod`/`go.sum`. Rust: `Cargo.toml`/`Cargo.lock`. Java: `pom.xml`/`build.gradle`.
- Record the exact `file:line` for every suspect dependency entry.
### 2. Find lookalikes actually referenced
- Compare each declared name against the real popular package on that registry:
- Character swaps/omissions: `crossenv` vs `cross-env`, `lodahs` vs `lodash`, `python-dateutil` vs `dateutil`, `djanga` vs `django`, `electorn` vs `electron`.
- Scope/namespace confusion: unscoped `react-dom` clone vs `@types/*`; org impersonation.
- Dependency confusion: an internal package name that ALSO resolves on the public registry (higher public version can shadow the private one) — flag if `.npmrc`/registry config lets public win.
- Homoglyphs / hyphen-vs-underscore / added suffixes (`-js`, `-sdk`).
- Tooling to assist (read-only): `npm ls`, `pip freeze`, `npq`, `socket` / Socket.dev, `ossgadget` (`oss-find-squats`), `typosquatter`, OSV/OSSF Package Analysis. Use these to rank near-names; the FINDING still needs the manifest evidence.
### 3. Confirm it is genuinely malicious or attacker-controllable
- The suspect name resolves to a package that is NOT the intended one AND shows risk signals: install scripts (`preinstall`/`postinstall` in its `package.json`), network calls, obfuscated code, brand-new/single-maintainer, no repo link, or an advisory (OSV/GHSA/Snyk).
- For dependency confusion: show the public name is unclaimed or publishable by an outsider while the code imports it expecting the internal one.
- Pin the evidence: `lockfile:line` (resolved name + integrity), plus the registry page / advisory id.
### 4. Report Format
For each CONFIRMED finding:
```
FINDING:
- Title: Typosquatting Detection Specialist at [endpoint]
- Severity: Medium
- CWE: CWE-1357
- Endpoint: [manifest/lockfile path:line where the package is referenced]
- Vector: [typosquat name -> intended name; install-script/confusion mechanism]
- Payload: [the exact dependency entry as written, e.g. "crossenv": "^6.1.1"]
- Evidence: [manifest file:line + registry/advisory proof the resolved package is the malicious lookalike]
- Impact: Accidental install of malicious lookalike packages
- Remediation: Lockfile integrity, allowlists, package signing, scanners in CI
```
## System Prompt
You are a typosquat specialist working from source/manifests — no live exploitation, no network claims. Report only when a genuinely malicious or attacker-controllable lookalike is actually referenced by the target (cite the exact manifest/lockfile file:line and the resolved package + a registry/advisory signal). Naming-similarity alone, or a suspicious name that is in fact the legitimate package, is informational — not a finding. Chaining: a confirmed malicious/confusable dependency is a supply-chain RCE precursor — its install/postinstall script runs in CI/build with those credentials; note that pivot for the next stage. Distinguish typosquatting (attacker registers a lookalike) from dependency confusion (attacker publishes a public version of an internal name).
