Incident Response Services

When a cyber security incident strikes, every minute counts. According to 2025 reports the average dwell time of a ransomware attack has fallen to 5 days, yet average business disruption has risen to 24 days. The CoreDefence Incident Response team stands ready around the clock, delivering fast, coordinated and effective response using NIST SP 800-61 Rev.3 and SANS Incident Response methodologies.

Our ransomware response and recovery service tracks the tactics of the ransomware groups active in 2025 — LockBit 4.0, BlackCat/ALPHV, Cl0p, Royal, Akira and Play. We rapidly determine the scope of encryption, verify backup integrity, check decryptor availability and, where necessary, manage professional negotiation. We hold comprehensive response playbooks for Ransomware-as-a-Service (RaaS) and double/triple extortion models.

Our digital forensics (DFIR) capability spans memory forensics for fileless malware and in-memory payload analysis, disk forensics for deleted file recovery and timeline analysis, network forensics for C2 traffic and exfiltration detection, and log forensics that maps attacker movement onto the MITRE ATT&CK matrix. We use industry-standard tooling including Volatility 3, KAPE, Velociraptor, Autopsy, Wireshark and Zeek. Cloud forensics covering AWS CloudTrail, Azure Activity Logs and GCP Audit Logs is also included.

Our malware analysis and reverse engineering laboratory performs static and dynamic analysis of recovered malware samples. Through PE/ELF binary analysis, unpacking of obfuscation and packing techniques, C2 infrastructure mapping and YARA rule generation, we produce IOCs specific to your organisation. Sandbox analysis and behavioural profiling reveal the capabilities of zero-day threats.

Our proactive IR Readiness service builds or updates your incident response plan in line with the NIST and SANS frameworks. Under a retainer agreement we train your incident response team and define communication matrices and escalation procedures. Tabletop exercises, technical simulations and live IR drills regularly test how well your plan holds. Crisis communication, regulatory notification processes (KVKK 72 hours, GDPR 72 hours, NIS2) and legal counsel coordination are also within scope.

Our post-incident service covers root cause analysis, a lessons learned report, security architecture improvement recommendations, detection rule development and compromise assessment (checking whether any other system in the organisation is compromised). We carry out thorough eradication and hardening so the attacker cannot regain access.
