Groupe Guyamier

Groupe Guyamier, also referred to as Guyamier Group, is a transport organization with its headquarters located in France. The company provides logistics and transportation services to clients, relying on information technology systems to manage client files, email communications, and order records. Its operations depend on the continuous availability of these IT resources to coordinate shipments and maintain business continuity.

On 29 November 2023 the group experienced a severe cyberattack that caused complete operational paralysis, rendering all client files, email access, and IT systems inaccessible. The attack was detected after computer screens froze and a virus was identified, prompting an immediate shutdown of all machines to prevent further spread. Attackers issued a ransom demand without specifying a monetary amount, which complicated efforts to contact clients due to the loss of order records and correspondence. In response, a crisis team consisting of forty personnel was mobilized to prioritize urgent measures and attempt the restoration of partial services. The organization noted that it had previously been targeted in a less significant cyber incident several years earlier, indicating a recurring exposure to such threats.

The 2023 attack was described by the group as a devastating and far‑reaching compromise of its servers, underscoring the critical role that its digital infrastructure plays in supporting transport and logistics activities. The ability to assemble a dedicated crisis response team of forty individuals reflects an established internal capacity for incident management. These details are drawn from the reported coverage of the incident in a regional news source.
