On February 13, 2024, ESN Act21, a subsidiary of Baker Tilly, fell victim to a significant cyberattack, rendering customer access to software and data impossible due to systems encryption. While the specific ransomware involved remains unspecified, initial investigations indicate that customer data was not exfiltrated but rather encrypted. Baker Tilly’s spokesperson assured that their teams, augmented by cybercrime experts, are fully engaged in addressing the incident, emphasizing that Act21’s software does not directly impact customers’ operational activities.
However, the spokesperson admitted the uncertainty surrounding the recovery timeline, stating it’s currently impossible to estimate when the data will be accessible again. Despite the disruption, customers, including Les Mousquetaires, Ubisoft, and the National Housing Agency, have been informed that the attack doesn’t directly impact their operational activities. Act21’s clientele, ranging from academic institutions to public services, faces the challenge of disrupted data access, highlighting the broader impact of cyber threats on diverse sectors.
