pantip.com Domain Breach Exposure Report

The telemetry indicates a significant exposure event affecting pantip.com, with 142,966 total events observed over the period from July 2025 to June 2026. The majority of these events, 86%, are classified as historical data breaches, totaling 122,972 incidents. Additionally, 19,994 active infostealer logs were detected, representing 14% of the total events. The data breaches are predominantly linked to "Combolist sources" (99.9%), suggesting compromised credential lists. The infostealer activity is heavily dominated by malware families such as Redline (31.3%), LummaC2 (15.7%), and Rhadamanthys (6.5%), which are known for exfiltrating sensitive information like credentials and financial data. The primary affected entities are clients (142,802), with a smaller number of employee-related events (164). The most targeted services are related to login and authentication endpoints on pantip.com, including "https://pantip.com/login" and "pantip.com/login". The geographical origin of the telemetry is predominantly Thailand (92.9%), with smaller amounts from Vietnam, India, and Pakistan. Given the high volume of historical data breaches and active infostealer activity targeting login credentials, this exposure poses a critical risk to both the organization and its users. The prevalence of known infostealer malware families indicates a sophisticated threat actor or widespread compromise. The focus for remediation should be on immediate credential hygiene, including mandatory password resets for all users, enhanced multi-factor authentication deployment, and a thorough investigation into the source of the "Combolist sources" to understand the initial breach vector. Security teams should also prioritize threat hunting for the identified malware families and review access logs for suspicious activity, particularly around the targeted login endpoints.
