oneok.com Domain Breach Exposure Report

The telemetry indicates a significant exposure event for oneok.com, with 40,990 historical data breaches and 1,775 active infostealer logs observed between July 2025 and June 2026. The majority of these events are linked to "Combolist sources" (84.2%) and "Database dumps" (15.8%), suggesting credential stuffing or account takeover attempts. The primary malware family associated with infostealer activity is "Redline" (93.1%), known for exfiltrating credentials and sensitive information. Employee accounts are heavily targeted, with 41,886 instances, and client accounts show 879 instances. Key targeted services include the main domain, password portals, and authentication services, with a notable concentration in the United States, Netherlands, and Germany. The prevalence of older Windows operating systems (e.g., Windows 7 x32, Windows Server 2008 R2 x32) among the affected systems may indicate unpatched vulnerabilities. Given the high volume of historical data breaches and active infostealer logs, coupled with the targeting of employee and client credentials, this situation presents a critical risk. The use of Redline infostealer and the reliance on credential stuffing tactics amplify the potential for further account compromise and data exfiltration. Prioritization should focus on immediate credential reset campaigns for all users, enhanced monitoring of authentication logs for suspicious activity, and a comprehensive review of security configurations for exposed services, particularly those related to authentication and user management. Addressing the use of outdated operating systems should also be a long-term remediation goal.
