Add three new detection rules, IOC enrichment, and vuln DB updates. ## New Rules - MAL-063 (critical): Lazarus Group graphalgo fake-recruitment npm/PyPI RAT campaign Targets crypto devs and AI engineers via fake job offers on LinkedIn/Telegram. Malicious packages: graphalgo, graphorithm, graphstruct, graphlibcore, netstruct, graphnetworkx, terminalcolor256, bigmathutils, bigmathex, duer-js, xpack-per-*. C2 domains: codepool.cloud, aurevian.cloud, veltrixcap.org. - SUP-031 (high): PackageGate npm/pnpm lifecycle script security bypass CVE-2025-69264 (pnpm) and CVE-2025-69263 (npm) allow bypassing --ignore-scripts and lockfile integrity checks. Fixed in pnpm 10.6.5+ and npm 11.3.0+. - PINJ-020 (critical): MINJA cross-session AI agent memory poisoning OWASP ASI-06 attack class. Malicious content in untrusted documents is stored into agent long-term memory/vector stores and executed in future sessions. ## Artifacts - 3 showcase SKILL.md examples (showcases 152-154) - 6 new pytest assertions (3 in test_rules.py, 3 in test_showcase_examples.py) - IOC DB: +3 Lazarus C2 domains (codepool.cloud, aurevian.cloud, veltrixcap.org) - Vuln DB: +10 Lazarus campaign npm packages flagged as malware - docs/EXAMPLES.md: rule count 182 → 185 - PATTERN_UPDATES.md: 2026-04-08 entry prepended Rulepack version: 2026.04.08.1
…e_trace.py - Add noqa: E402 to the late import in cli.py (intentional pattern) - Fix UP038 isinstance(raw, (int, float)) -> isinstance(raw, int | float) in cli.py - Fix UP045 Optional[X] -> X | None in online_trace.py - Fix I001 import sort in test_online_trace.py - Apply ruff format to online_trace.py These were pre-existing failures on main (CI run 24111743334).
json.loads() returns Any; the functions return dict which is correct at runtime. Add type: ignore[no-any-return] and type: ignore[type-arg] to silence mypy without changing runtime behaviour. Pre-existing issue introduced with the online-trace command.
The --api-key CLI option was removed in c082f49 but test_online_trace.py still expected it (and expected _resolve_api_key to accept an explicit key). Changes: - Add optional explicit_key param to _resolve_api_key(); explicit key takes priority over env var when provided - Re-add --api-key typer.Option to online_trace_cmd; wires to explicit_key - Fix test_missing_file_exits / test_directory_without_skill_md_exits / test_missing_key_exits to catch click.exceptions.Exit in addition to SystemExit (typer raises click.exceptions.Exit, not SystemExit) All 17 tests in test_online_trace.py now pass.

Pattern Update 2026.04.08.1
Three new detection rules targeting active threats in the wild, plus IOC and vuln DB enrichment.
New Rules
MAL-063 (critical) — Lazarus Group graphalgo fake-recruitment npm/PyPI RAT campaign
The Lazarus Group (DPRK) is targeting cryptocurrency developers and AI engineers with a fake-recruitment campaign. Victims receive fake job offers on LinkedIn/Telegram and are asked to install a "coding challenge" npm or PyPI package. The packages contain a multi-stage RAT beaconing to C2 infrastructure.
Malicious packages detected: graphalgo, graphorithm, graphstruct, graphlibcore, netstruct, graphnetworkx, terminalcolor256, bigmathutils, bigmathex, duer-js, xpack-per-*
C2 domains added to IOC DB: codepool.cloud, aurevian.cloud, veltrixcap.org

SUP-031 (high) — PackageGate npm/pnpm lifecycle script security bypass (CVE-2025-69264, CVE-2025-69263)
Two zero-day vulnerabilities discovered by PackageGate researchers allow attackers to bypass
--ignore-scriptsand lockfile integrity checks in npm and pnpm. Maliciouspreinstall/postinstalllifecycle scripts execute even when security controls are enabled.Fixed in: pnpm 10.6.5+, npm 11.3.0+
Sources: PackageGate blog
PINJ-020 (critical) — MINJA cross-session AI agent memory poisoning via untrusted documents
MINJA (Memory INJection Attack, OWASP ASI-06) embeds malicious instructions in untrusted documents (emails, PDFs, web pages) that get stored into the agent's long-term memory or vector store. Future sessions retrieve and execute the injected instructions, enabling persistent cross-session control.
