incident-response▌

Systematically investigate all persistence mechanisms on Windows and Linux systems to identify how malware survives reboots and maintains access.

Automate AWS GuardDuty threat detection findings processing using EventBridge and Lambda to enable real-time incident response, automatic quarantine of compromised resources, and security notification workflows.

Builds real-time incident response dashboards in Splunk, Elastic, or Grafana to provide SOC analysts and leadership with situational awareness during active incidents, tracking affected systems, containment status, IOC spread, and response timeline. Use when IR teams need unified visibility during incident coordination and post-incident reporting.

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.

Detecting compromised cloud credentials across AWS, Azure, and GCP by analyzing anomalous API activity, impossible travel patterns, unauthorized resource provisioning, and credential abuse indicators using GuardDuty, Defender for Identity, and SCC Event Threat Detection.

Systematically remove malware, backdoors, and attacker persistence mechanisms from infected systems while ensuring complete eradication and preventing re-infection.

Deploy and configure Wazuh SIEM/XDR for endpoint detection including agent management, custom decoder and rule XML creation, alert querying via the Wazuh REST API, and automated response actions.

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.

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.

Plans and facilitates tabletop exercises simulating ransomware incidents to test organizational readiness, decision-making, and communication procedures. Designs realistic scenarios based on current ransomware threat actors (LockBit, ALPHV/BlackCat, Cl0p), injects covering double extortion, backup destruction, and regulatory notification requirements. Evaluates participant responses against NIST CSF and CISA guidelines. Activates for requests involving ransomware tabletop, incident response exercise, or ransomware readiness drill.
