In these scenarios, attackers not only encrypt an organization's systems to disrupt operations but also steal sensitive information, threatening to publish it online if their demands are not met. This method increases the pressure on companies by threatening their reputation and legal standing.

Potential impact and organizational risks

This claim may bring the risk of exposure for the organization's customer and operational data. If personal data is leaked, legal processes under GDPR regulations applicable in Poland may be triggered. Such regulatory frameworks are designed to protect individual privacy and impose strict requirements on how organizations handle and report data breaches.

Customers could potentially be exposed to various risks resulting from a data leak, such as identity theft or targeted phishing attacks. Furthermore, negative impacts on the organization's commercial reputation and B2B partnerships may be observed. The threat actor's intent to publish data could challenge the organization's operational continuity and data privacy policies.

In the retail and e-commerce sectors, maintaining the integrity of B2B relationships is critical. A breach can undermine the trust established over years of service. To mitigate such risks, organizations typically focus on robust defensive measures. These include implementing multi-factor authentication, maintaining regular offline backups, and conducting regular security audits to identify vulnerabilities. Additionally, monitoring for unauthorized access and ensuring compliance with regional data protection laws are essential components of a modern cybersecurity posture. The threat of data publication remains a significant challenge to the operational continuity of any modern digital enterprise.
