Jeremylongshore Claude Code Plugins Plus Skills Security Incident Responder

Assists with security incident response, investigation, and remediation. This skill is triggered when the user requests help with incident response, mentions specific incident types (e.g., data breach, ransomware, DDoS), or uses terms like "incident response plan", "containment", "eradication", or "post-incident activity". It guides the user through the incident response lifecycle, from preparation to post-incident analysis. It is useful for classifying incidents, creating response playbooks, collecting evidence, constructing timelines, and generating remediation steps. Use this skill when needing to respond to a "security incident".

mukul975

Designs and implements a ransomware-resilient backup strategy following the 3-2-1-1-0 methodology (3 copies, 2 media types, 1 offsite, 1 immutable/air-gapped, 0 errors on restore verification). Configures backup schedules aligned to RPO/RTO requirements, implements backup credential isolation to prevent ransomware from compromising backup infrastructure, and establishes automated restore testing. Activates for requests involving ransomware backup planning, backup resilience, air-gapped backup design, or backup recovery point objective configuration.

investigating-ransomware-attack-artifacts

2

mukul975

Identify, collect, and analyze ransomware attack artifacts to determine the variant, initial access vector, encryption scope, and recovery options.

analyzing-linux-elf-malware

2

mukul975

Analyzes malicious Linux ELF (Executable and Linkable Format) binaries including botnets, cryptominers, ransomware, and rootkits targeting Linux servers, containers, and cloud infrastructure. Covers static analysis, dynamic tracing, and reverse engineering of x86_64 and ARM ELF samples. Activates for requests involving Linux malware analysis, ELF binary investigation, Linux server compromise assessment, or container malware analysis.

implementing-honeypot-for-ransomware-detection

2

mukul975

Deploys canary files, honeypot shares, and decoy systems to detect ransomware activity at the earliest possible stage. Configures canary tokens embedded in strategic file locations that trigger alerts when ransomware attempts encryption, uses honeypot network shares that mimic high-value targets, and deploys Thinkst Canary appliances for comprehensive deception-based detection. Activates for requests involving ransomware honeypots, canary files, deception technology for ransomware, or early ransomware alerting.

monitoring-darkweb-sources

2

mukul975

Monitors dark web forums, marketplaces, paste sites, and ransomware leak sites for mentions of organizational assets, leaked credentials, threatened attacks, and threat actor communications to provide early warning intelligence. Use when establishing dark web monitoring coverage, investigating specific data breach claims, or enriching incident investigations with dark web context. Activates for requests involving dark web OSINT, leak site monitoring, credential exposure, Recorded Future dark web, or Tor hidden service intelligence.

performing-ransomware-response

2

mukul975

Executes a structured ransomware incident response from initial detection through containment, forensic analysis, decryption assessment, recovery, and post-incident hardening. Addresses ransom negotiation considerations, backup integrity verification, and regulatory notification requirements. Activates for requests involving ransomware response, ransomware recovery, crypto-ransomware, data encryption attack, ransom payment decision, or ransomware containment.

recovering-from-ransomware-attack

2

mukul975

Executes structured recovery from a ransomware incident following NIST and CISA frameworks, including environment isolation, forensic evidence preservation, clean infrastructure rebuild, prioritized system restoration from verified backups, credential reset, and validation against re-infection. Covers Active Directory recovery, database restoration, and application stack rebuild in dependency order. Activates for requests involving ransomware recovery, post-encryption restoration, or disaster recovery from ransomware.

hunting-for-shadow-copy-deletion

2

mukul975

Hunt for Volume Shadow Copy deletion activity that indicates ransomware preparation or anti-forensics by monitoring vssadmin, wmic, and PowerShell shadow copy commands.

analyzing-ransomware-leak-site-intelligence

2

mukul975

Monitor and analyze ransomware group data leak sites (DLS) to track victim postings, extract threat intelligence on group tactics, and assess sector-specific ransomware risk for proactive defense.

detecting-ransomware-precursors-in-network

2

mukul975

Detects early-stage ransomware indicators in network traffic before encryption begins, including initial access broker activity, command-and-control beaconing, credential harvesting, reconnaissance scanning, and staging behavior. Uses network detection tools (Zeek, Suricata, Arkime), SIEM correlation rules, and threat intelligence feeds to identify ransomware precursor patterns such as Cobalt Strike beacons, Mimikatz network signatures, and RDP brute-force attempts. Activates for requests involving pre-ransomware detection, network-based ransomware indicators, or early warning ransomware monitoring.

building-soc-playbook-for-ransomware

2

mukul975

Builds a structured SOC incident response playbook for ransomware attacks covering detection, containment, eradication, and recovery phases with specific SIEM queries, isolation procedures, and decision trees. Use when SOC teams need formalized response procedures for ransomware incidents aligned to NIST SP 800-61 and MITRE ATT&CK ransomware techniques.

performing-ransomware-incident-response

2

mukul975

Execute a structured ransomware incident response including containment, decryption assessment, recovery from backups, and eradication of ransomware persistence mechanisms.
