What is vps-security?

A security guide for protecting virtual private servers and other infrastructure used in red-team operations. It covers acquisition, server hardening, encrypted storage, command-and-control setup, monitoring, and teardown.

It is for planning and securing VPS-based red-team infrastructure, including SSH, firewalls, encryption, network routing, monitoring, and recovery or teardown.

Attack infrastructure can expose operators, credentials, client data, and activity if it is poorly isolated or left running after use.

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	$0.00266	$0.01524
Opus 5.5	$0.00106	$0.00610
Sonnet 5.5	$0.00053	$0.00305
Haiku 4.5	$0.00027	$0.00152

Security

Grade A, and why

vps-security 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.

VPS Security

End-to-end security for red team attack infrastructure — from anonymous acquisition through hardened provisioning, encrypted storage, C2 deployment, continuous monitoring, and rapid teardown.

This skill treats every VPS as a disposable, compartmentalized node in an attack infrastructure graph. The goal is never "secure a server for production" — it is "make this node operationally useful while leaving zero forensic trail when it burns."

Reference Files

Reference	When to Read
`references/anonymous-acquisition.md`	Acquiring VPS anonymously — providers, payment, identity separation
`references/hardened-provisioning.md`	First-boot hardening playbook — SSH, firewall, port knocking, sysctl, updates
`references/encrypted-storage.md`	LUKS, VeraCrypt, encrypted swap, nuke keys, plausible deniability
`references/c2-infrastructure.md`	C2 hardening, redirectors, domain fronting, malleable profiles, TLS
`references/teardown-and-recovery.md`	Rapid teardown, secure wipe, snapshot destruction, backup/recovery

Opsec Profile Integration

Every action in this skill adapts to the active opsec profile. Check the current profile before starting any VPS work:

node "${CLAUDE_PLUGIN_ROOT}/scripts/opsec-profile.js" show

Profile	Acquisition	Provisioning	Monitoring	Teardown
loud	Any provider, credit card OK	Basic hardening, password SSH OK	Optional	Manual cleanup
normal	Mainstream provider, prepaid card	Key-only SSH, UFW, fail2ban	Logwatch daily	Delete VPS via panel
stealth	Privacy provider, crypto payment	Port knocking, no DNS, encrypted disk	Auditd + remote syslog	Secure wipe + snapshot delete
paranoid	Bulletproof/offshore, Monero only	Multi-layer: knock + Tor-only SSH, full LUKS	Real-time alerts, tripwire	Nuke key + header destroy + provider account burn

Changes

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.
