Our methodology

The technical investigation begins with a mapping of the incident. The workstations and servers concerned by the incident are identified, as are the malicious actions carried out (compromising machines, unauthorized reading of emails, publication or access to confidential and strategic data, dissemination of defamatory information, denial of service, etc.).

It continues with the identification of the scenario, which aims to rigorously trace the modus operandi, the authors and the vulnerability at the origin of the intrusion. The security engineers here seek to collect tangible evidence that you can present, especially to an insurance company.

Finally, a phase of reverse-engineering allows to dissect and understand the attack or computer virus, so as to durably protect the victim company against this type of attack.

Crisis management assistance includes :

  • Technical help to restart efficiently in degraded mode until the switch to nominal mode
  • Human and legal assistance in post-incident action counseling
  • Advice on corrective action
  • Legal analysis and advice on the possible consequences of the incident
