Decepticon is an autonomous red-team agent that coordinates AI agents, security tools, sandboxes, and supporting services for authorized cybersecurity assessments. Security researchers and red teams can run it through its Docker stack, cloud service, command-line interface, or Python SDK, with the catalogue entries representing its available skills.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
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 →
- high YARA Match · line 73 YARA rule matched a known malware signature (reverse shell, backdoor, ransomware, C2 framework, or info stealer).Fix: Remove the malware payload or compromised file entirely. Investigate how it entered the skill and audit all other artifacts for additional indicators of compromise.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00042 | $0.05055 |
| Opus 5 | $0.00021 | $0.02527 |
| Sonnet 5 | $0.00008 | $0.01011 |
| Haiku 4.5 | $0.00004 | $0.00505 |
Grade A, and why
volt-typhoon 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 8d 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.

Volt Typhoon (BRONZE SILHOUETTE, Vanguard Panda, Insidious Taurus) — Adversary Emulation Profile
Volt Typhoon is a People's Republic of China (PRC) state-sponsored cyber actor active since at least mid-2021, tracked by MITRE ATT&CK as G1017 and known by the aliases BRONZE SILHOUETTE (Secureworks), Vanguard Panda (CrowdStrike), Voltzite (Dragos), Insidious Taurus (Palo Alto Unit 42), DEV-0391 (Microsoft's pre-naming designation), and UNC3236 (Mandiant). Unlike financially motivated crews, Volt Typhoon's hallmark is patient, ultra-stealthy pre-positioning inside US critical infrastructure — communications, energy, water, and transportation — using almost exclusively living-off-the-land (LOTL) techniques and legitimate stolen credentials, with little or no custom malware on victim hosts. CISA, the NSA, and the FBI assess the group is establishing persistent access not for immediate espionage value but to enable lateral movement to operational technology (OT) for potential disruptive or destructive attacks during a future geopolitical crisis or conflict. Its operational signature is hands-on-keyboard activity, native OS binaries, web shells on edge appliances, and traffic proxied through compromised small-office/home-office (SOHO) routers to blend into normal network noise.
Attribution & motivation
- Sponsor / nation: People's Republic of China (PRC), state-sponsored. CISA/NSA/FBI and Microsoft attribute the activity to a PRC nexus; Microsoft assessed the actor as PRC state-sponsored with high confidence.
- Motivation: Strategic pre-positioning / preparation of the environment rather than classic data-theft espionage. Microsoft assessed with moderate confidence that the campaign pursues capabilities that could disrupt critical communications infrastructure between the US and the Asia region during a future crisis. CISA's AA24-038A frames the intent as enabling destructive or disruptive cyberattacks against OT in the event of conflict. This is closer to destructive/wartime-enabling than financial or influence motivation.
- Confidence: Attribution to a PRC state-sponsored actor is high (joint government + multiple vendor concurrence). The disruptive-intent assessment is moderate confidence per the original reporting.
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.

volt-typhoon is a skill published in the GitHub repository PurpleAILAB/Decepticon (5,452 stars, last pushed 8d ago), licensed Apache-2.0. It adds 42 tokens to every session and 5,055 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
