Ransomware Response & Recovery

Modern ransomware is a business interruption event, a data breach, a legal matter and an extortion negotiation at the same time. Aureon runs all four tracks in parallel so that the business recovers faster and the record of what happened is beyond dispute.

Overview

Encryption is usually the last step of an intrusion that began days or weeks earlier. Our response does not stop at restoring servers: we identify how the adversary entered, what they took, where they still have access and what has to change before the environment can be trusted again.

We have led recoveries for organisations in financial services, manufacturing, healthcare, retail and the public sector, often working alongside insurers, counsel and specialised extortion advisers under a single coordinated plan.

When to engage us

  • Encryption notes on servers, shares or hypervisor consoles.
  • Backups deleted, disabled or encrypted ahead of a main event.
  • A threat actor claiming to hold your data, with or without encryption.
  • A third party, supplier or managed service provider reporting a ransomware incident that touches your data or connectivity.
  • An insurer or counsel instructing an independent forensic response.
What we deliver

Capabilities within Ransomware Response & Recovery.

01

Rapid containment

Isolation of affected segments, credential resets, hypervisor and backup protection, and emergency hardening of remote access, all while preserving evidence for the investigation.

02

Scope and impact assessment

Identification of the ransomware family and affiliate tradecraft, encrypted and exfiltrated assets, affected systems and realistic recovery options.

03

Exfiltration and leak-site analysis

Determination of what data was taken, assessment of leak-site claims and samples, and monitoring of the actor's infrastructure for publication.

04

Extortion handling within the law

Structured support for communications with the threat actor, decision frameworks for boards and insurers, and sanctions screening of the actor against EU, UK, US and UAE lists before any payment is even considered.

05

Decryption and restoration

Validation of decryptors, staged restoration from clean backups, rebuild of identity infrastructure and verification that eradicated access does not return.

06

Hypervisor and backup forensics

Investigation of attacks on VMware ESXi and vCenter, Hyper-V and backup platforms, which are now routinely targeted to maximise business impact.

07

Regulatory and contractual notifications

Evidence-based support for GDPR 72-hour notifications, NIS2 and DORA incident reporting, UAE PDPL obligations, customer contracts and listing requirements.

08

Post-incident hardening

Remediation plan covering identity, remote access, segmentation, backup immutability, detection coverage and the specific weaknesses the attacker exploited.

Method

Four tracks, one plan.

Track 1

Business continuity

Priority services identified with the business, interim operations supported, recovery sequencing agreed with IT and third parties.

Track 2

Forensic investigation

Entry point, timeline, tooling and exfiltration established from evidence. Findings feed containment, notification and the extortion decision.

Track 3

Extortion management

Threat actor communications, sanctions screening, valuation of the data at stake and a documented decision record for the board and the insurer.

Track 4

Legal and regulatory

Coordination with counsel, insurers, data protection authorities, sector regulators and law enforcement, with every notification grounded in evidence.

Deliverables

What you receive.

Clear, usable outputs for executives, technical teams, insurers and regulators.

  • Incident command structure, cadence and communication plan from day one.
  • Scope and impact assessment, updated as evidence develops.
  • Exfiltration assessment with data categorisation for notification decisions.
  • Sanctions screening record and extortion decision documentation.
  • Forensic report, indicators of compromise and detection content.
  • Hardening roadmap and validated clean-state attestation for insurers and auditors.
Questions we are asked

Frequently asked questions.

Do you negotiate with ransomware groups?

We manage communications and decision support within a strict legal framework, together with counsel and the insurer. Sanctions screening is mandatory before any payment is considered, and we document every step so the decision record withstands scrutiny.

Can you guarantee data recovery?

No responsible firm can. We maximise the chance of recovery by protecting backups early, validating decryptors in isolation and rebuilding from trusted sources. We tell clients what is realistic before they commit to a path.

How long does recovery take?

It depends on scope, backups and identity infrastructure. Our priority sequencing restores the services that matter most first, while the investigation runs in parallel so that recovery does not reintroduce the attacker.

Will you work with our managed service provider?

Yes. We frequently coordinate the response for organisations whose infrastructure is operated by a third party, and we are explicit about roles, evidence handling and accountability.
