Under Active Attack

Executive Summary

In August 2026, a data theft campaign named 'City-Forum' was identified, targeting misconfigured Salesforce Experience Cloud and ServiceNow customer portals. The attackers exploited overly permissive sharing rules and portal configurations, allowing unauthorized access to sensitive data through anonymous guest accounts. The campaign, traced to the IP address 158.220.87.79 associated with the domain city-forum.com, has been active since at least March 2025, affecting various sectors including telecommunications, finance, enterprise software, and public services.

The 'City-Forum' attacks underscore the critical importance of securing SaaS platforms against unauthorized access. Organizations must review and tighten guest-user permissions and sharing settings to prevent data exposure. This incident highlights a growing trend of cybercriminals exploiting misconfigurations in widely used platforms, emphasizing the need for continuous monitoring and proactive security measures.

Why This Matters Now

The 'City-Forum' attacks highlight the urgent need for organizations to secure their SaaS platforms against unauthorized access. Misconfigurations in widely used platforms like Salesforce and ServiceNow can lead to significant data breaches, emphasizing the importance of continuous monitoring and proactive security measures.

Frequently Asked Questions

The 'City-Forum' campaign is a series of data theft attacks exploiting misconfigured Salesforce Experience Cloud and ServiceNow customer portals, allowing unauthorized access to sensitive data through anonymous guest accounts.

Cloud Native Security Fabric Mitigations and ControlsCNSF

Based on the attack progression modeled above, these are the defensive controls that would constrain each stage.

Aviatrix Zero Trust CNSF is pertinent to this incident as it could have limited the attacker's ability to exploit misconfigured guest user permissions, thereby reducing unauthorized data access and exfiltration.

Initial Compromise

Control: Cloud Native Security Fabric (CNSF)

Mitigation: Implementing Aviatrix CNSF would likely have constrained unauthorized access by enforcing identity-based policies, thereby limiting exposure of sensitive data.

Privilege Escalation

Control: Zero Trust Segmentation

Mitigation: Aviatrix Zero Trust Segmentation would likely have restricted the attacker's access scope, limiting their ability to interact with sensitive data beyond their initial access.

Lateral Movement

Control: East-West Traffic Security

Mitigation: Aviatrix East-West Traffic Security would likely have prevented any potential lateral movement, ensuring the attack remained isolated to the initial entry point.

Command & Control

Control: Multicloud Visibility & Control

Mitigation: Aviatrix Multicloud Visibility & Control would likely have provided comprehensive monitoring, potentially detecting and alerting on unauthorized data access activities.

Exfiltration

Control: Egress Security & Policy Enforcement

Mitigation: Aviatrix Egress Security & Policy Enforcement would likely have restricted unauthorized data exfiltration by controlling outbound data flows.

Impact (Mitigations)

Implementing Aviatrix Zero Trust CNSF would likely have reduced the overall impact by limiting the scope of unauthorized access and data exfiltration.

Data Exposure

Potential exposure of sensitive customer data, including personally identifiable information (PII), contact details, and case records, due to misconfigured guest user permissions in Salesforce Experience Cloud and ServiceNow portals.

Recommended Actions

  • • Review and correct guest user permissions in Salesforce Experience Cloud and ServiceNow portals to prevent unauthorized data access.
  • • Implement Zero Trust Segmentation to enforce least privilege access and restrict unauthorized interactions.
  • • Utilize Multicloud Visibility & Control to monitor and detect anomalous activities across cloud environments.
  • • Apply Egress Security & Policy Enforcement to control and monitor data exfiltration attempts.
  • • Conduct regular security assessments and audits to identify and remediate misconfigurations in cloud services.
