Cyber incident: what to demand from IT, and in what order

Friday, late afternoon: IT reports an intrusion and says it is already reinstalling the servers. You have a few hours to decide what stays preserved.

The course

Why this course

The lawyer's role in the first hours: preserve before remediating, record every action and make sure the forensic examination can provide answers later.

In the first hours of an incident, everyone works to get the systems back. That is right for the business. The problem is the order. Whoever reinstalls, restores a backup on top or changes passwords without noting it erases the answers that the insurer, the ANPD (Brazil's National Data Protection Agency) and the judge will ask for.

Evidence is lost in predictable places: cloud logs with short retention, reformatted servers, the unknown device someone took to their desk. And it is lost in the mix. When nobody records what IT did, the examination cannot separate what the attacker did from what the response did.

The lawyer does not contain the attack: that belongs to IT or the contracted provider. The lawyer decides the order and what gets recorded. The course shows how, with real cases.

  • Require preservation before any reinstallation, formatting or backup restoration.
  • Identify the logs that expire first and request their export with hash.
  • Keep the incident diary, with every password changed, account disabled and machine isolated.
  • Reconcile notice to the insurer with preservation.
  • Frame the three questions the forensic examination answers later: how they got in, what they took, since when.

Cases in class

The cases used in class

REAL CASE · ANONYMISED

The mini computer hidden on the network

A company found on its internal network a mini computer with its own 4G modem. The examination showed that it had scanned more than a thousand machines and accessed shared folders with a network credential. The report also recorded the loss: IT had handled the device, and collecting fingerprints became impossible.

REAL CASE · ANONYMISED

The intrusion that did not start where it seemed

An attack hit an organisation's on-premises domain and its cloud. The examination placed the events from two domain controllers and the cloud logs on a single timeline. The on-premises domain had been compromised almost half an hour before the cloud.

REAL CASE · ANONYMISED

Proof that a client was not affected

A platform shared by many organisations had its server compromised, with code to capture card data. Working on a forensic copy whose integrity was verified before the examination, the expert separated the intruder, the legitimate administrators and the response team, and showed that the capture did not reach the client demanding an answer.

Practice and materials

Ready to use the next day

Hands-on exercise

In groups, participants receive the scenario of an intrusion discovered on a Friday afternoon, with what IT has already done in the first two hours. In 15 minutes, they put the measures in the right order, mark what was lost and what can still be saved, and list the technical points for the notice to the insurer. The correction uses the course checklist.

Materials provided
  • Checklist: what to demand from IT, in order: the measures for the first 24 hours, in the right sequence.
  • Incident diary template: a record of each response action, with time, author and reason.
  • Table of the traces that expire first: short-retention logs and what to request.
  • Agenda for the first meeting with IT: the questions to ask before authorising remediation.
Questions on the topic
Do we have to wait for the examination before restoring the systems?
For the report, no. For preservation, yes. Forensic imaging and export of the logs come before reinstalling or restoring. When time is short, IT exports the logs under guidance, with hash.
What changes if the company has cyber insurance?
The law requires the insured to notify the insurer promptly and to mitigate the effects of the loss, and prohibits altering or destroying elements related to it (Law 15,040/2024, Brazil's Insurance Contract Act, arts. 66 and 68). Documented preservation makes it possible to comply with both. How each duty applies is for the lawyer to decide.
