analyzing-uefi-bootkit-persistence
by mukul975analyzing-uefi-bootkit-persistence helps investigate UEFI-level persistence, including SPI flash implants, ESP tampering, Secure Boot bypasses, and suspicious UEFI variable changes. It is built for firmware triage, incident response, and analyzing-uefi-bootkit-persistence for Security Audit work with practical, evidence-driven guidance.
This skill scores 78/100, which means it is a solid listing candidate for directory users who need a focused UEFI bootkit persistence analysis workflow. The repository gives enough concrete analysis guidance, tooling references, and defensive use framing that an agent can trigger it with less guesswork than a generic cybersecurity prompt, though users should still expect some implementation-specific adaptation.
- Strong triggerability: the description and 'When to Use' section explicitly target UEFI malware analysis, firmware persistence investigation, Secure Boot bypass detection, and boot chain integrity verification.
- Operational depth: the body is substantial, with workflow-oriented content plus code examples and a reference file for chipsec-based SPI flash and UEFI variable operations.
- Agent leverage: the included Python analysis script and known bootkit signatures/IOCs provide concrete artifacts for firmware-focused triage and detection.
- No install command in SKILL.md, so users may need to wire the skill into their workflow manually.
- The repository appears defensive-analysis oriented rather than a turnkey end-to-end toolchain, so some cases will still require external firmware access, chipsec setup, or analyst judgment.
Overview of analyzing-uefi-bootkit-persistence skill
What this skill does
The analyzing-uefi-bootkit-persistence skill helps you investigate UEFI-level persistence, including SPI flash implants, EFI System Partition (ESP) tampering, Secure Boot bypass activity, and suspicious UEFI variable changes. It is most useful for incident responders, firmware security reviewers, and defenders doing analyzing-uefi-bootkit-persistence for Security Audit work.
Who it fits best
Use this skill when a system keeps re-compromising after reimaging, when Secure Boot state looks wrong, or when early-boot malware is suspected. It is a strong fit for firmware triage, endpoint hardening reviews, and boot-chain integrity checks where ordinary malware prompts are too shallow.
What makes it different
This analyzing-uefi-bootkit-persistence skill is not just about listing bootkit names. It is oriented around decision points that matter in real investigations: where persistence lives, what artifacts to inspect first, and how to verify firmware and ESP integrity without guessing.
How to Use analyzing-uefi-bootkit-persistence skill
Install and activation
Install with the repo path for the skill: npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-uefi-bootkit-persistence. Use the skill when your task mentions UEFI malware analysis, boot chain integrity, Secure Boot bypass detection, or firmware persistence investigation.
Give the skill the right inputs
The best analyzing-uefi-bootkit-persistence usage starts with concrete context, not a vague “check this machine.” Include platform, firmware access level, whether you have a live system or only a dump, Secure Boot status, known symptoms, and any hashes, paths, or variable names you already collected. Strong inputs produce stronger triage.
Workflow that gets useful output
Start with SKILL.md for the operating sequence, then read references/api-reference.md for the available chipsec commands and scripts/agent.py for the detection logic and known bootkit indicators. If you are adapting the skill, mirror its flow: confirm scope, inspect firmware, review ESP artifacts, check Secure Boot and UEFI variables, then compare findings against known persistence patterns.
Prompt shape that works
A good prompt for the analyzing-uefi-bootkit-persistence guide is specific and bounded, for example: “Analyze this SPI dump and ESP snapshot for UEFI persistence, explain whether Secure Boot controls were altered, and list the next verification steps for an IR report.” If you have no dump yet, ask for a collection plan first rather than a verdict.
analyzing-uefi-bootkit-persistence skill FAQ
Is this only for advanced analysts?
No. The analyzing-uefi-bootkit-persistence skill is usable by beginners if they already know they need firmware-focused triage. The main learning curve is evidence handling: you need the right dump, the right partition data, and enough environment detail to avoid false conclusions.
How is it different from a normal prompt?
A normal prompt may describe UEFI persistence in broad terms. This skill is better when you need a repeatable workflow, tool-aware guidance, and a sharper reading of artifacts like SPI flash regions, ESP modifications, Secure Boot variables, and bootkit indicators.
When should I not use it?
Do not use it for general endpoint malware hunting, standard Windows persistence, or boot issues with no firmware signal. If your evidence is limited to user-space logs or one suspicious file, this skill is probably too specialized.
Does it work well in a Security Audit workflow?
Yes, especially when you need a defensible review of boot-chain controls, firmware baselines, and Secure Boot configuration. For analyzing-uefi-bootkit-persistence for Security Audit, it is most valuable when paired with firmware dumps, baseline comparisons, and documented collection steps.
How to Improve analyzing-uefi-bootkit-persistence skill
Provide evidence, not just suspicion
The strongest results come from artifacts: SPI images, ESP file listings, Secure Boot state, UEFI variable output, and hashes of suspicious EFI binaries. If you only say “I think it’s a bootkit,” the analysis will stay generic. If you include concrete data, the skill can narrow likely persistence paths.
Tell it what changed
State whether the issue followed a reinstall, disk swap, BIOS update, or Secure Boot toggle. Those details help distinguish firmware persistence from disk-only tampering and make the analyzing-uefi-bootkit-persistence skill more decisive.
Ask for one output type at a time
If you need an IR note, a verification checklist, and a technical explanation, ask for them separately. The skill is most effective when you request a single deliverable per pass, then iterate with follow-up evidence.
Watch for common failure modes
The main mistake is overcalling persistence from incomplete data. Another is treating every EFI modification as malicious. Improve the analyzing-uefi-bootkit-persistence install and usage experience by asking for confidence levels, alternative explanations, and the exact checks that would confirm or rule out firmware compromise.
