Ransomware Recovery
Rapid ransomware containment, decryption advisory, clean restoration, and root-cause elimination to minimise dwell time and business disruption.
Ransomware Recovery
Ransomware attacks have evolved from opportunistic nuisances into sophisticated, targeted campaigns conducted by organised criminal groups who spend weeks inside your network before detonating encryption. Modern ransomware operators exfiltrate data before encrypting it, compromise backup systems to eliminate recovery options, and use double and triple extortion to maximise pressure on victims.
Intelliroot's Ransomware Recovery service provides expert-led crisis response from the moment of detection through to clean restoration of operations. Our ransomware specialists have managed responses across healthcare, financial services, manufacturing, and critical infrastructure — bringing technical expertise and measured judgement to one of the most high-pressure situations any organisation faces.
Ransomware Recovery Requires Specialist Expertise
Backups Are Targeted First
Professional ransomware operators consistently target backup infrastructure before deploying encryption. Shadow copy deletion, backup server compromise, and cloud backup API abuse are standard attacker procedures. Validating backup integrity before recovery is essential.
Encryption Is the End, Not the Beginning
By the time ransomware detonates, attackers have typically been in the environment for 10-21 days. Rebuilding without identifying and closing the initial access vector guarantees re-compromise — often within days of restoration.
Extortion Requires Expert Assessment
Double and triple extortion scenarios — threatened data publication, DDoS, and customer/supplier notification — require experienced assessment of threat credibility, data sensitivity, and negotiation options. These decisions should never be made without specialist guidance.
Recovery Without Eradication Fails
Restoring systems to production while attacker persistence mechanisms remain in the environment is a common and costly mistake. Complete eradication must be verified before any restored system returns to production — a process that requires systematic hunting, not just an antivirus scan.
Our Response Process
- 01
Immediate Containment
Network isolation of affected segments, credential invalidation for compromised accounts, and disabling of attacker C2 channels. Stop active encryption and attacker lateral movement.
- 02
Scope Assessment
Determine the full scope of encryption, data exfiltration, and backup compromise. Identify the ransomware variant and assess decryption options including free decryptors and negotiation.
- 03
Backup Validation & Recovery Planning
Assess backup integrity and availability. Develop recovery sequence prioritising critical business systems. Validate that backups are clean (pre-compromise) before restoration begins.
- 04
Attacker Eradication
Complete eradication of all attacker persistence — backdoors, scheduled tasks, compromised credentials, rogue accounts, and implanted tools. Validated through active threat hunting before recovery.
- 05
Clean Restoration
Supervised restoration of systems from validated clean backups. Security hardening applied during rebuild. Monitoring deployed before systems return to production.
- 06
Root Cause & Post-Incident Report
Identify and close the initial access vector. Deliver post-incident report for regulatory notifications, insurance claim, and board reporting.
