Our Ransomware Recovery Process

A ransomware attack is not a standard IT outage; it is a highly coordinated, multi-stage, and actively hostile network intrusion. When an enterprise discovers encrypted files, ransom notes, and paralyzed hypervisors, the standard IT playbook completely breaks down. Attempting to restore backups without neutralizing the underlying threat actor guarantees a secondary, often more devastating, encryption event.

At Akira Ransomware Recovery, we approach data restoration through the lens of strict digital forensics and enterprise incident response. Our overarching objective is to bridge the gap between catastrophic data loss and secure operational continuity. To achieve this, our engineering teams operate under a rigid, six-phase incident response lifecycle designed to contain the threat, identify the root cause, sanitize the environment, and safely recover the data.

This document details the exact operational workflow our forensic engineers and security architects execute from the moment we are engaged during an active cyber crisis. Every phase of this methodology aligns with our strict Ethical Guidelines and our commitment to absolute data integrity.

Phase 1: Emergency Triage & Absolute Containment

The first 24 hours of a ransomware engagement are critical. Threat actors frequently utilize automated scripts to continuously hunt for newly connected storage arrays or online backups. If the environment is not properly locked down, the encryption cycle will continue to spread, compounding the data loss.

Network Isolation & C2 Severance

Our initial objective is to stop the bleeding. We work closely with the client’s internal IT and network teams to immediately sever the affected environment from the broader internet and any uninfected corporate subnets. Crucially, we do not arbitrarily power down servers, as doing so destroys vital volatile memory (RAM) that often contains the decrypted payload or memory-resident encryption keys necessary for forensic analysis.

Instead, we isolate the environment logically at the switch or firewall level. We immediately identify and block all known Command and Control (C2) IP addresses, effectively blinding the threat actors and severing their remote access to the network. This stops active data exfiltration processes and prevents the attackers from pushing secondary payloads.

EDR Deployment

Once the perimeter is secured, we rapidly deploy advanced Endpoint Detection and Response (EDR) sensors across the entire server matrix and endpoint fleet. This grants our incident response team complete visibility into all running processes, registry modifications, and network connections, allowing us to actively hunt for persistent threats that survived the initial containment.

Phase 2: Forensic Root Cause Analysis (RCA)

Restoring data into a compromised environment is a recipe for disaster. Before a single file can be safely decrypted, we must answer two fundamental questions: How did the attackers get in, and what backdoors have they left behind? This requires deep digital forensics.

Identifying the Initial Access Vector (IAV)

Our digital forensics team begins parsing system artifacts, including Windows Event Logs, firewall traffic logs, IIS web server logs, and Active Directory authentication histories. We meticulously trace the threat actor’s lateral movement backward through the network to pinpoint the exact Initial Access Vector (IAV).

In many modern attacks involving Akira, LockBit, or BlackCat, the IAV often stems from compromised Virtual Private Network (VPN) credentials lacking Multi-Factor Authentication (MFA), an unpatched edge appliance (such as a vulnerable firewall or hypervisor), or the abuse of legitimate remote management tools (RMM) like AnyDesk or ScreenConnect. We preserve all evidence of this intrusion according to our strict Evidence Preservation standards for future cyber insurance claims and regulatory reporting.

Hunting for Persistence Mechanisms

Threat actors rarely rely on a single point of entry. Once inside, they establish multiple persistence mechanisms to ensure they retain access even if their primary entry point is closed. Our analysts hunt for rogue scheduled tasks, malicious WMI (Windows Management Instrumentation) subscriptions, unauthorized newly created administrative accounts, and hidden Cobalt Strike beacons. Every artifact is mapped, documented, and prepared for eradication.

Phase 3: Cryptographic Assessment & Viability Analysis

Concurrent with the forensic investigation, Our Malware Researchers focus entirely on the malware payload itself. We must determine the mathematical feasibility of data recovery.

Payload Extraction and Reverse Engineering

Our engineers extract the specific ransomware binary responsible for the encryption. Using isolated, air-gapped laboratory environments, we disassemble the payload to analyze its exact cryptographic schema. We determine what algorithms are being utilized (e.g., RSA-4096 combined with ChaCha20) and examine the key generation routines.

If the encryption is mathematically flawless and no backups remain, we provide the client with an honest, transparent viability assessment. We do not offer false hope or engage in deceptive recovery practices.

Phase 4: Data Sanitization & Zero-Trust Reconstruction

Once the environment is understood and the persistence mechanisms are mapped, the eradication phase begins. The objective is to reconstruct the underlying infrastructure so that it is inherently hostile to the threat actors.

Identity Infrastructure Rebuilding

In almost all enterprise ransomware incidents, the threat actors successfully compromise the domain controllers and steal the Active Directory database (NTDS.dit), giving them complete control over all network identities. To prevent a catastrophic “Golden Ticket” attack from occurring post-recovery, we systematically rebuild the identity infrastructure.

We force a global password reset across all user and service accounts, rotate the KRBTGT account password twice to invalidate forged Kerberos tickets, remove all unauthorized administrative accounts, and enforce stringent Multi-Factor Authentication (MFA) policies globally. We patch the vulnerable edge appliances identified during the RCA and transition the network to a hardened, zero-trust architecture.

Phase 5: Decryption & Data Restoration

With the environment sanitized and secured, we transition to the actual recovery of the encrypted data. Deploying a decryption utility is a highly volatile process that requires extreme caution and adherence to our Decryptor Testing Process.

Safe Execution and Data Integrity

Whether we are utilizing a proprietary decryptor developed by our internal engineers, an open-source tool, or a utility obtained via negotiation (if authorized by the client under strict OFAC compliance), we never run it blindly on production storage arrays.

We first execute the decryption utility on isolated subsets of data—such as heavily fragmented SQL databases or complex VMware ESXi datastores—to verify that the tool does not cause header corruption or data truncation. Once the integrity of the decrypted files is mathematically verified using SHA-256 hash comparisons, we deploy the decryption tools at scale. Our engineers monitor memory usage, CPU load, and I/O throughput to ensure the decryption process runs efficiently without crashing the host servers.

Phase 6: Post-Incident Reporting & Hardening

Data restoration is not the end of the engagement. The final phase of our recovery process ensures that the organization is protected from future intrusions and is fully prepared for the inevitable legal and regulatory fallout of a major cyber incident.

Comprehensive Forensic Documentation

We generate a highly detailed, court-ready Post-Incident Report (PIR). This documentation outlines the exact timeline of the attack, the precise Initial Access Vector, a catalog of all compromised systems, and cryptographic proof of recovery. This report is critical for satisfying the requirements of cyber insurance underwriters, external legal counsel, and regulatory compliance bodies (such as HIPAA, GDPR, or the SEC).

Strategic Security Hardening

Finally, our Principal Security Architects provide the client’s leadership team with a strategic roadmap. We outline specific architectural improvements, backup immutability recommendations, and enhanced monitoring protocols necessary to elevate the organization’s security posture and ensure they are never paralyzed by a ransomware event again.
