These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

apt34-oilrig scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

APT34 (OilRig, Helix Kitten, Hazel Sandstorm) — Adversary Emulation Profile

APT34 — tracked as OilRig, Helix Kitten, Hazel Sandstorm, Earth Simnavaz, Crambus, Cobalt Gypsy / COBALT GYPSY, IRN2, Evasive Serpens, EUROPIUM, ITG13, and TA452 (MITRE ATT&CK G0049) — is a suspected Iranian state-sponsored cyber-espionage group operational since at least 2014. It conducts long-running, reconnaissance-heavy intrusions against Middle Eastern and international organizations, favoring spearphishing for initial access, heavy use of PowerShell/VBScript backdoors, custom DNS-tunneling C2, supply-chain and trust-relationship abuse, and patient credential harvesting. The group continually re-tools (BONDUPDATER → SideTwist → cloud/Exchange-based C2) and is notable for living-off-the-land tradecraft, password-filter-DLL credential capture, and exfiltrating data through victim-owned Microsoft Exchange servers to blend with legitimate mail flow.

Attribution & motivation

  • Suspected sponsor: Iran. FireEye/Mandiant assesses APT34 "works on behalf of the Iranian government based on infrastructure details that contain references to Iran, use of Iranian infrastructure, and targeting that aligns with nation-state interests." Multiple vendors (Trend Micro, Microsoft, CrowdStrike) link the cluster to Iranian intelligence services.
  • Motivation: Strategic cyber espionage — long-term reconnaissance and credential/data theft to advance Iranian geopolitical interests in the region. Primary intent is intelligence collection, not financial gain. (A separate but related Iranian destructive operation, ZeroCleare wiper (S1151), is associated with the same cluster, indicating latent destructive capability.)
  • Confidence: High that the activity is Iranian state-aligned espionage; the precise sponsoring agency varies by vendor naming. Attribution of any single intrusion should be treated as suspected unless backed by collected infrastructure/tooling overlap.

Targeting

  • Sectors: Financial/banking, government, energy/oil & gas, chemical, telecommunications, critical infrastructure, and aviation/transport.
  • Regions: Primarily the Middle East — Gulf Cooperation Council states (UAE, Saudi Arabia, Kuwait, Qatar, Bahrain), plus Israel; with international reach into the U.S. and other regions via supply-chain and trust-relationship pivots.
  • Victim profile: Government ministries and state-aligned enterprises in strategic sectors; the group frequently compromises one organization (e.g., HR/job portals, telecoms) and abuses that trust to reach higher-value government targets.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
