Anthropic Cybersecurity Skills is a library of structured cybersecurity procedures for AI agents, covering security domains and mappings to established security frameworks. It is for authorized security analysis, penetration testing, incident response, research, defense, and education across compatible AI platforms. The catalogue entries package parts of this library as agent skills, instructions, or a plugin.
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.

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 | $0.00083 | $0.03014 |
| Opus 5 | $0.00042 | $0.01507 |
| Sonnet 5 | $0.00017 | $0.00603 |
| Haiku 4.5 | $0.00008 | $0.00301 |
Grade A, and why
analyzing-outlook-pst-for-email-forensics 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 13d 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.

Analyzing Outlook PST for Email Forensics
Overview
Microsoft Outlook PST (Personal Storage Table) and OST (Offline Storage Table) files are critical evidence sources in digital forensics investigations. PST files store email messages, calendar events, contacts, tasks, and notes in a proprietary binary format based on the MAPI (Messaging Application Programming Interface) property system. Forensic analysis of these files enables recovery of deleted emails (from the Recoverable Items folder), extraction of email headers for tracing message routes, analysis of attachments for malware or exfiltrated data, and reconstruction of communication patterns. Modern PST files use Unicode format with 4KB pages and can grow up to 50GB, while legacy ANSI format is limited to 2GB.
When to Use
- When investigating security incidents that require analyzing outlook pst for email forensics
- When building detection rules or threat hunting queries for this domain
- When SOC analysts need structured procedures for this analysis type
- When validating security monitoring coverage for related attack techniques
Prerequisites
- libpff/pffexport (open-source PST parser)
- Python 3.8+ with pypff or libratom libraries
- MailXaminer, Forensic Email Collector, or SysTools PST Forensics (commercial)
- Microsoft Outlook (optional, for native PST access)
- Sufficient disk space for extracted content
PST File Locations
| Source | Path |
|---|---|
| Outlook 2016+ Default | %USERPROFILE%\Documents\Outlook Files*.pst |
| Outlook Legacy | %LOCALAPPDATA%\Microsoft\Outlook*.pst |
| OST Cache | %LOCALAPPDATA%\Microsoft\Outlook*.ost |
| Archive | %USERPROFILE%\Documents\Outlook Files\archive.pst |
Analysis with Open-Source Tools
libpff / pffexport
# Export all items from PST file
pffexport -m all evidence.pst -t exported_pst
# Export only email messages
pffexport -m items evidence.pst -t exported_emails
# Export recovered/deleted items
pffexport -m recovered evidence.pst -t recovered_items
# Get PST file information
pffinfo evidence.pst
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
