Cyber Incident Victim: Tegma Gestão Logística

On or around May 1, 2023, Tegma Gestão Logística, a publicly traded company identified by its stock ticker TGMA3, reported that it had suffered a cyber attack. The company disclosed that the incident affected some of its own servers as well as servers belonging to its controlled subsidiaries. This attack resulted in the partial unavailability of the company's systems, indicating a direct impact on its operational technology infrastructure. The organization's internal security systems, specifically its operational and protection systems, successfully detected the ongoing malicious activity. Upon detection, the company immediately activated its pre-established security protocols and control measures in response to the incident.

In its initial public communication regarding the event, Tegma Gestão Logística stated that its primary systems remained intact despite the attack. This suggests that while the incident caused disruption to certain segments of its infrastructure, the core operational technology responsible for running its main logistics and management functions was not compromised or severely damaged. The company did not specify the exact nature of the attack, such as whether it was ransomware, a denial-of-service attack, or another form of intrusion, nor did it identify the specific servers or systems that were rendered unavailable. The disclosure confirmed the involvement of the company's subsidiaries, indicating the incident's scope extended beyond the parent corporation to its controlled entities.

As part of its incident response plan, Tegma engaged an external consulting firm specializing in cybersecurity to assist with the situation. The company described this external support as being of recognized reference within the area of expertise, indicating the engagement of a reputable digital forensics and incident response (DFIR) partner. This action was taken to bolster the internal response efforts, likely involving forensic analysis to determine the root cause of the breach, assess the full scope of the compromise, and aid in the remediation and recovery processes. The engagement of a third-party expert is a standard procedure for managing significant cybersecurity incidents to ensure a comprehensive and technically sound response.

A key finding from the initial investigation, which the company communicated, was that no evidence of data exfiltration had been identified. Tegma Gestão Logística explicitly stated it had not identified the leakage of any client data or any personal data processed by the company. This early assessment was crucial for informing stakeholders, including clients and partners, that the incident, while disruptive to operations, had not resulted in a privacy breach or the compromise of sensitive information. The company’s announcement focused on the operational impact of system unavailability rather than a data breach, framing the incident primarily as an availability issue. The full extent of the operational downtime and the specific business processes affected were not detailed in the immediate disclosure. The financial impact, including any potential costs associated with the response and recovery efforts or losses stemming from the operational disruption, was not quantified in the initial statement released on May 1, 2023. The company's communication strategy appeared focused on assuring stakeholders of the integrity of its main systems and the proactive steps taken to address the issue.
