Description
On September 18, 2024, Polish clothing retailer Ochnik received notification of a cybersecurity incident involving unauthorized access to customer data stored by its technology partner. Attackers exploited a security vulnerability in the partner's software infrastructure to gain access to one of its technical accounts, subsequently compromising files containing Ochnik customer information. The breach exposed personal data including full names, delivery addresses, email addresses, and telephone numbers, though the company confirmed attackers did not access customer passwords, transaction histories, or other authentication credentials. Ochnik's technology partner implemented immediate containment measures upon detecting the intrusion, blocking system access and eliminating the vulnerability that enabled the breach. The company formally notified Poland's Personal Data Protection Office (UODO), national police authorities, and the Computer Emergency Response Team (CERT) about the incident within required regulatory timelines.
No evidence of malicious use of the stolen data had been identified at the time of reporting, with Ochnik assessing the probability of negative consequences as low. The company warned affected customers about potential risks including unsolicited marketing communications (spam) via email or SMS, phishing attempts by entities posing as legitimate organizations to extract additional personal information, and fraudulent phone calls or emails attempting to harvest supplementary details. Internal investigations confirmed the attackers operated through compromised partner systems rather than directly breaching Ochnik's own infrastructure. The retailer directed customer inquiries to Data Protection Officer Małgorzata Rzeszotarska via a dedicated email address while advising vigilance against suspicious communications. Ochnik emphasized ongoing monitoring of online accounts for unauthorized activity and recommended reporting any suspected fraud attempts to law enforcement or data protection authorities.
