Ready For IT 2022: Back to attacks on new digital uses

08/06/2022 Thanks to Ready for IT organizers so we can shared a feedback regarding our incident response services (CSIRT Synacktiv) and red team activities. Below is a summary of the intervention.

Unransomware

31/01/2022 During a ransomware incident, CSIRT Synacktiv noticed that the bitlocker mechanism was used to encrypt company and user files. This blogpost does not intend to retrace the whole incident response process. The idea is to illustrate how we managed (or not) to recover encryption keys and save a few workstations from their terrible fate. The incident took place few months ago.
