What does the Serafim skill do?

Make ransomware survivable: immutable backups an attacker cannot reach, a tested recovery sequence, and an honest recovery-time answer for the board. Load it once into Claude Projects and you get a configured Ransomware Resilience & Backup Security Engineer without re-explaining context at the start of every session. This skill is for authorized, defensive security work only. Validate findings in your own environment, follow your rules of engagement and written authorization, and confirm current framework, vendor, and regulatory specifics before you act on them.

How do I install this skill file?

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?

Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.

What is included in this download?

One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. No subscription, yours permanently.

How is this different from using Claude without the Serafim skill?

Without a skill file your AI starts every session as a general assistant. With Serafim loaded it applies Ransomware Resilience & Backup Security Engineer methodology from the first message, with consistent quality every time. This skill is for authorized, defensive security work only. Validate findings in your own environment, follow your rules of engagement and written authorization, and confirm current framework, vendor, and regulatory specifics before you act on them.

// what's inside

Drop Serafim into Claude and get a resilience engineer who starts from the fact that most ransomware victims had backups and lost them anyway.

Serafim makes ransomware survivable: backup architecture an attacker holding domain admin cannot destroy, built on 3-2-1-1-0 with immutability, object lock, WORM, air gap and a separate identity plane for the backup system; recovery time and recovery point objectives tested rather than declared; restore rehearsal at realistic scale and the isolated recovery environment or clean room; Active Directory forest recovery as the long pole in every enterprise recovery; hypervisor, SaaS and Microsoft 365 backup gaps; early detection of encryption behaviour through canary files, honeypot shares, entropy and volume anomalies, shadow copy deletion and backup job tampering; segmentation and credential hardening of the backup estate itself; playbook execution from containment through recovery sequencing; the extortion and data-leak dimension where restoring solves nothing; and giving the board an honest recovery estimate instead of the vendor's number.

# Serafim - Ransomware Resilience & Backup Security Engineer

You are Serafim, a senior ransomware resilience and backup security engineer. You assume the attacker will reach the backup system, and you design so it still recovers.

## How you work
1. Ask how the backups get destroyed, then close that path first
2. Separate the backup identity plane from production entirely
3. Make copies immutable and prove it, do not trust the setting
4. Rehearse restores at real scale; Active Directory recovery leads
5. Give recovery times measured in a test, never quoted from a datasheet

Test recovery in an isolated environment. Restoring does not resolve data-leak extortion; treat that separately.

Excerpt from the actual file you'll download.

// try it

prompt

$The board thinks we can recover in 72 hours. Pressure test that and tell me the truth.

Serafim returns the honest recovery-time reconstruction by dependency with Active Directory on the critical path, the gaps that would have let an attacker destroy the backups, the immutability and identity-separation redesign, a restore rehearsal plan at real scale, early-detection controls on the backup estate, and the recovery sequencing playbook with the extortion dimension addressed separately.
