Part of Respond and prove

Incident response and ransomware

When an incident is under way, containment comes first: we stop the spread, preserve the evidence, work out what happened and restore operations in a defined order.

What is included

  • Triage and containment of the incident
  • Evidence preservation from the first moment
  • Analysis of logs, accounts, email and endpoints to reconstruct the attack
  • Eradication of the attacker's access and recovery of services
  • Technical communication with leadership while the incident is open
  • Post-incident report with causes and recommendations

This is for you if

  • You suspect unauthorized access to accounts, email or servers
  • Your files appeared encrypted or a ransom note is showing
  • You want to review your response plan before you need it

How we do it

  1. Contain

    We isolate what is affected and cut the attacker's access without destroying evidence.

  2. Investigate

    We reconstruct what happened, how they got in, what they touched and which data may have been exposed.

  3. Eradicate and recover

    We close the way in, clean up and bring services back in the order your business needs.

  4. Learn and strengthen

    We document the incident and leave a plan so it does not happen again through the same route.

An incident, moment by moment

Walk through an illustrative incident, from an email to the data, and see at each moment what can be contained, what evidence exists and what the team does.

Illustrative simulationIt is an example incident: it matches no client and its times are not a response commitment or an SLA.

Slide or use the arrow keys. Times are hours and minutes since the initial access.

00:00 since the initial access

Initial access by email

Containment

What can be stopped

No intrusion is confirmed yet. Isolating the message and the devices that opened it prevents the next step.

Evidence

What evidence exists

The original email with its headers, the mail server logs and the list of who received it.

Action

What the team does

Triage: confirm what happened, preserve evidence from the first moment and tell whoever decides.

00:27 since the initial access

Compromised credential

Containment

What can be stopped

The account can be blocked, active sessions closed and credentials reset before they are used on other systems.

Evidence

What evidence exists

The account's sign-in logs, where the accesses came from and the activity in the mailbox.

Action

What the team does

Contain the affected account and analyze logs and accounts to learn whether the credential was used, and from where.

01:40 since the initial access

Privilege escalation

Containment

What can be stopped

Isolate the devices involved and cut the attacker's access to accounts with more permissions.

Evidence

What evidence exists

Changes to accounts and permissions, and the logs of the devices and servers the attacker moved through.

Action

What the team does

Isolate without destroying evidence, reconstruct the route taken and begin removing the attacker's access.

03:15 since the initial access

Data access

Containment

What can be stopped

Close the exit routes and protect the data not yet reached.

Evidence

What evidence exists

File access and transfer logs, which show which data may have been compromised.

Action

What the team does

Brief leadership with technical clarity, eradicate the access, restore services and prepare the post-incident report.

Incident investigation and ransomware response

Sectors served

  • Legal
  • Private sector

Services offered / delivered

  • Incident response and infrastructure forensic analysis
  • Ransomware and lateral movement investigation
  • Correlation of logs and indicators

Context

This group brings together investigations of affected infrastructure and response support, with the evidence and limits specific to each incident.

Documented interventions

  • Analysis of logs, account activity, connections and tools associated with the incident.
  • Construction of timelines and cross-checking across systems, sources and indicators.
  • Documentation of impact and recommendations for containment, recovery and improved controls.

Documented results

  • Traceability of access, propagation and control exposure was provided in the cases investigated.
  • The reports distinguished documented facts, indications and recommendations for the response.

Scope of the result

We do not claim full recovery, restoration times or losses avoided without evidence. Attributions of ransomware family or authorship that are inconsistent or inconclusive are left out.

Methodology

Forensic analysis of logs and artifacts, temporal correlation and documentation of evidence.

Frequently asked questions

There is an incident under way. What do I do first?

Disconnect the affected machines from the network, keep everything you see (ransom notes, emails, logs) and contact us before shutting down, wiping or reinstalling. Those actions can destroy useful evidence.

Should we pay the ransom?

It is a business and legal decision that we do not make for you. We give you the technical facts to decide: what was encrypted, whether usable backups exist and what the risk of data exposure is.

Can you recover my encrypted files?

It depends on the case: on the variant, on the available backups and on what can be restored. We assess it from the first analysis and tell you what is possible. Cyber Recovery is a service of its own.
