What is red-team-tactics?

A set of red-team tactics for simulating how an attacker might move through a system, based on the MITRE ATT&CK framework. Red teaming is authorized security testing that imitates real attacks to find weaknesses.

Use it to plan adversary simulations, map an attack surface, examine attack phases, test detection evasion, and structure security findings and reports.

It provides a way to organize testing from reconnaissance and initial access through discovery, data collection, and impact. This helps teams consider both attack paths and ways to detect them.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00026	$0.01001
Opus 5	$0.00013	$0.00500
Sonnet 5	$0.00005	$0.00200
Haiku 4.5	$0.00003	$0.00100

Security

Grade B, and why

red-team-tactics scanned grade B with 1 finding 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 6d 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.

Harvests environment variablesmediumData exfiltration

Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Red Team Tactics

Adversary simulation principles based on MITRE ATT&CK framework.

1. MITRE ATT&CK Phases

Attack Lifecycle

RECONNAISSANCE → INITIAL ACCESS → EXECUTION → PERSISTENCE
       ↓              ↓              ↓            ↓
   PRIVILEGE ESC → DEFENSE EVASION → CRED ACCESS → DISCOVERY
       ↓              ↓              ↓            ↓
LATERAL MOVEMENT → COLLECTION → C2 → EXFILTRATION → IMPACT

Phase Objectives

Phase	Objective
Recon	Map attack surface
Initial Access	Get first foothold
Execution	Run code on target
Persistence	Survive reboots
Privilege Escalation	Get admin/root
Defense Evasion	Avoid detection
Credential Access	Harvest credentials
Discovery	Map internal network
Lateral Movement	Spread to other systems
Collection	Gather target data
C2	Maintain command channel
Exfiltration	Extract data

2. Reconnaissance Principles

Passive vs Active

Type	Trade-off
Passive	No target contact, limited info
Active	Direct contact, more detection risk

Information Targets

Category	Value
Technology stack	Attack vector selection
Employee info	Social engineering
Network ranges	Scanning scope
Third parties	Supply chain attack

3. Initial Access Vectors

Selection Criteria

Vector	When to Use
Phishing	Human target, email access
Public exploits	Vulnerable services exposed
Valid credentials	Leaked or cracked
Supply chain	Third-party access

4. Privilege Escalation Principles

Windows Targets

Check	Opportunity
Unquoted service paths	Write to path
Weak service permissions	Modify service
Token privileges	Abuse SeDebug, etc.
Stored credentials	Harvest

red-team-tactics is a skill published in the GitHub repository diillson/chatcli (90 stars, last pushed today), licensed Apache-2.0. It adds 26 tokens to every session and 1,001 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (harvests environment variables). It is 94% identical to red-team-tactics, differing in 2 lines, and is treated as a copy.
