Petco disclosed a security incident due to which some customer-related data was accessible from the internet, stating in a regulatory filing that personal information had been exposed and that it will notify those who have been affected. The pet products and services company said it had found the issue itself, fixed the application settings that allowed the exposure, and removed the files from public access.
What Petco Disclosed About Its Customer Data Exposure
The details of the exposed data were revealed in a notice Petco submitted to California’s attorney general, which blamed one of its software applications and how it was configured for allowing files to be viewed on the internet. The company said it acted immediately to limit access and put in place additional technical controls. Petco did not say which categories of personal information were exposed, or how many people were affected.

Sample letters filed with state regulators show that Petco is providing free credit and identity monitoring to those notified.
Petco has not described the contents of what was at risk for any individual whose data was affected. On average, most companies will offer assistance when certain personally identifiable information might be vulnerable, even as they continue to investigate with respect to both the nature and the duration of an exposure.
Scope Signaled in State Filings and Notifications
California law mandates the reporting of breaches impacting at least 500 state residents, so this scope indicates a non-trivial incident. Mid-Missouri is affected. Some of those notifications also went out to Massachusetts residents and a few in Montana, proving that the fallout has typical nationwide reach. The total could increase once Petco finishes its investigation and more municipalities issue notices.
California’s data breach statute requires companies to explain what happened, what information was potentially involved, and the steps taken in response. If driver’s license or Social Security numbers are involved, organizations must include credit monitoring thought to be capable of providing resolution if data is misused. Petco’s offer of monitoring jibes with those norms, though the company did not verify which data fields were breached.
Why Misconfiguration Incidents Persist for Retailers
Security misconfiguration is one of the top causes of breaches and data exposure, frequently appearing in the OWASP Top 10 and other industry reports. With today’s cloud and microservices, even one wide-open policy can be the door to a large amount of data access. Retailers and service brands are usual victims because they keep so much contact and account data associated with loyalty programs and e-commerce transactions.
A record number of U.S. data compromises, due in part to errors and cloud-related exposures, were cataloged by the Identity Theft Resource Center in 2023. IBM’s Cost of a Data Breach study has consistently found that detection and containment can take months, not to mention the fact that incidents related to human error or misconfigured systems are both common and extremely expensive — especially where sensitive personal information is concerned. Discovering it earlier, as Petco notes here, also helps limit the exposure window.

Legal and Regulatory Exposure Under California Law
Beyond state notification laws, California businesses also are subject to requirements formed by the California Consumer Privacy Act and its amendments compelling reasonable security as well as offering a limited private right of action for certain breaches where nonencrypted personal information was involved. The most typical ends to investigations are multi-state probes, consumer lawsuits, and consent agreements where inadequate safeguards or delayed notifications are discovered.
Petco said it has taken “additional security precautions” in the wake of the incident. Enterprises in similar cases usually go through a full config audit, increase access logging and rotate keys and credentials, as well as assume least-privilege access — all things that authorities/assessors often see as components of an acceptable remediation plan.
What Customers Affected Should Do to Protect Themselves
For those who receive a notice, customers are urged to consider registering for offered monitoring services, double-check bank and card statements for any strange activity, and set up account alerts. You also can put in place a fraud alert or a credit freeze with the major credit bureaus to help further minimize the risk of new-account fraud. Passwords that were reused with Petco-related accounts should be changed, and two-factor authentication enabled on all accounts for which it’s available.
Beware of spear-phishing attempts that mention pet acquisitions, rewards account numbers, or grooming and veterinarian visits because threat actors frequently weaponize the situational awareness contained in exposed records. Real companies do not ask for full Social Security numbers, bank PINs, or one-time codes over email or text.
What To Watch Next as Petco Investigates the Incident
Among the obvious questions are how many customers were affected — and whether their most sensitive personal data was made available to anyone who had no business seeing it. There’s also the issue of how long the files were accessible, or whether Petco can access any sort of logs that would show whether people attempted to view or download this information. There will be further state filings and any formal regulatory statements that will further illustrate the reach.
The episode is a reminder for retailers that configuration drift and overly permissive settings are among the leading enterprise risks, analysts say. Ongoing validation of access controls, automatic detection of public exposure, and the secure-by-default templates discussed here are key control measures — ones with potential to minimize fallout when errors happen and prevent customer data from falling into the wrong hands.
