Incident response support and forensic review after ransomware

When this support is useful

Following ransomware, unauthorized access, or suspected data theft, management may need to make sense of technical communications, recovery activity, and requests from its advisers. An engagement may cover an initial documentary assessment, oversight of an examination already under way, or an independent review of conclusions that will inform business decisions or legal assessments.

Establish the evidence before drawing conclusions

Using materials authorized for review, the work reconstructs the known timeline, available sources, and outstanding questions. It separates evidence of an incident from its impact, potential exfiltration, and attribution. An extortion message, for example, is treated as a claim requiring verification, while conclusions about affected systems need relevant supporting records.

The evidence plan identifies records, documents, and information to request from the responsible parties, setting out their provenance, integrity, time coverage, and limitations. Preservation priorities are discussed with those managing the technical response so that collection, changes, and handovers remain documented.

What the engagement delivers

Deliverables may include a triage memo, a timeline linked to supporting records, an evidence and technical questions matrix, and a methodological review of reports received. These materials help the client identify which conclusions are supported, which require further examination, and who should be responsible for each outstanding question.

Working alongside the technical response

In an illustrative scenario where production resumes before the extent of unauthorized access is established, the review distinguishes evidence of recovery from evidence needed to reconstruct the intrusion. Containment, laboratory acquisitions, and system restoration remain the responsibility of the appointed technical teams. The practice provides the agreed analytical and methodological support in coordination with the client’s business and legal representatives. Timing, availability, and collaboration arrangements are established at the start of the engagement.

Starting the conversation

An initial assessment requires a general description of the event, the decision that needs support, relevant deadlines, and details of the professionals already involved. The proposal defines scope, required materials, and expected deliverables; any transfer of confidential documents is arranged separately through appropriate channels.
