prnt.sc Domain Breach Exposure Report

The domain prnt.sc has been associated with a significant number of historical data breaches, accounting for 96% of the observed events. Additionally, there is evidence of active infostealer logs, representing 4% of the events. The timeline indicates a surge in both employee and client-related events starting in late 2025 and peaking in early to mid-2026, with a notable increase in employee-related incidents during March, April, and May of 2026. Malware families like LummaC2 and Redline have been identified in relation to these events. The primary leak repository classification points to "Combolist sources," suggesting compromised credential lists are a major factor. Given the high volume of historical data breaches and the presence of active infostealer logs, this exposure presents a critical risk. The involvement of malware families known for credential theft and the classification of "Combolist sources" indicate a strong likelihood of compromised user accounts and potential for further unauthorized access. Prioritization should focus on immediate incident response to contain any active threats, followed by a thorough investigation into the root cause of the data breaches and the compromised credentials. Remediation efforts should include credential reset campaigns for affected users, enhanced monitoring for suspicious activity, and strengthening access controls.
