AutoZone [1] [2] [3] [4] [5], a major auto parts retailer [3], recently experienced a data breach due to a critical vulnerability in its MOVEit file-transfer program [4]. This breach, carried out by the Clop ransomware gang, resulted in the unauthorized access and exfiltration of various types of sensitive data belonging to nearly 185,000 individuals, including 293 residents of Maine [1].


On May 28, 2023 [2] [5], AutoZone discovered that its MOVEit file-transfer program had been compromised by the Clop ransomware gang. Exploiting a vulnerability associated with MOVEit [2] [5], an unauthorized third party was able to access and extract a range of data, including employee names [2] [3] [5], email addresses [2] [5], parts supply details [2] [5], tax information [2] [3] [5], payroll documents [2] [5], Oracle database files [2] [5], and production and sales information [5].

In response to the breach, AutoZone promptly initiated the process of notifying affected individuals and advising them to monitor their accounts for any suspicious activity. Additionally, the company is offering complimentary credit monitoring and identity protection services to mitigate potential harm [1]. AutoZone became aware of the breach in August and confirmed its nature and scope in September [3]. The hackers were able to obtain personal information such as full names and social security numbers.

This incident is part of a larger series of attacks targeting the MOVEit file transfer application [1], impacting over 2,000 organizations and an estimated 62 million people [3]. It serves as a stark reminder of the ongoing need for organizations to continuously adapt and strengthen their cybersecurity measures. Furthermore, it underscores the importance of collaboration between the public and private sectors in combating cybercrime and safeguarding individuals and businesses from the detrimental effects of data breaches [3].

The data leaked by the cybercriminals amounts to approximately 1.1GB in size [5]. It is anticipated that the Clop ransomware gang will receive extortion payments totaling over $75 million from the affected companies.


The AutoZone data breach highlights the significant impacts that can result from vulnerabilities in file-transfer programs. It serves as a reminder for organizations to prioritize cybersecurity and implement robust measures to protect sensitive data. Moving forward, it is crucial for both the public and private sectors to work together in order to effectively combat cybercrime and prevent future breaches. The incident also underscores the importance of individuals remaining vigilant and taking proactive steps to monitor their personal information for any signs of unauthorized activity.
