Operational risks may include the need for process updates and potential disruptions to existing security workflows. Reputational risks are estimated to be low, around 2-3%, as the acquisition is likely to be viewed positively by stakeholders.

SOC Recommendations — Immediate Actions

• Monitor Splunk's Agentic SOC updates and releases for new capabilities and features introduced by the WideField Security acquisition.
• Review and update existing threat investigation and detection processes to incorporate identity, credentials, sessions, and blast radius analysis.
• Engage with Cisco and Splunk representatives to discuss potential integration and training requirements for the new capabilities.

MITRE ATT&CK Mapping

• Tactic: Reconnaissance (TA0043): The acquisition may introduce new capabilities for identity and credentials analysis, potentially supporting reconnaissance efforts.
• Tactic: Credential Access (TA0006): The focus on credentials and sessions may indicate an increased emphasis on credential access and management.

Detection Opportunities

Log sources to monitor may include identity and access management systems, session logs, and network traffic captures. Network signatures may involve unusual patterns of credential usage or session establishment. Behavioral indicators could include suspicious identity or credential-related activity, such as multiple failed login attempts or unusual session durations.

Threat Hunting Recommendations

• Hunt for unusual patterns of credential usage or session establishment, potentially indicating reconnaissance or credential access attempts.
• Investigate suspicious identity or credential-related activity, such as multiple failed login attempts or unusual session durations.
• Monitor for potential blast radius expansion, where attackers may attempt to move laterally within the network using compromised credentials or sessions.
