Source SecurityWeek

Description

Threat actors are leveraging the file-sharing service for payload delivery in AitM phishing and BEC attacks. The post Phishers Abuse SharePoint in New Campaign Targeting Energy Sector appeared first on SecurityWeek .

Impact

For European organizations, especially those in the energy sector, this threat poses significant risks including credential compromise, unauthorized access to critical systems, and potential disruption of energy supply operations. The use of SharePoint as a delivery mechanism increases the likelihood of successful phishing attempts due to the platform's trusted status within organizations. Compromised credentials can lead to lateral movement within networks, data exfiltration, and manipulation of operational technology systems. Given the critical nature of energy infrastructure in Europe, successful attacks could have cascading effects on national security, economic stability, and public safety. Additionally, regulatory implications such as GDPR breaches may arise if sensitive personal or operational data is exposed. The medium severity rating suggests that while the threat is serious, it does not currently exploit software vulnerabilities but relies on social engineering, which can be mitigated with proper awareness and controls.

Defensive guidance

1. Implement advanced email filtering solutions that specifically analyze URLs and attachments hosted on trusted platforms like SharePoint to detect malicious content. 2. Conduct targeted security awareness training for employees in the energy sector, emphasizing the risks of phishing links hosted on legitimate services such as SharePoint. 3. Enforce strict access controls and permissions on SharePoint sites to limit exposure of sensitive documents and reduce the attack surface. 4. Deploy multi-factor authentication (MFA) for all access to SharePoint and related corporate resources to prevent unauthorized access even if credentials are compromised. 5. Monitor SharePoint activity logs for unusual access patterns or file uploads that could indicate malicious activity. 6. Establish incident response procedures tailored to phishing and BEC scenarios, including rapid credential revocation and forensic analysis. 7. Collaborate with IT and security teams to whitelist or block suspicious SharePoint URLs based on threat intelligence. 8. Regularly update and patch all collaboration platforms and associated software to minimize potential exploitation avenues beyond phishing.
