HEURRemoteAdmin.GoToResolve.gen is identified as a Potentially Unwanted Application associated with the GoTo Resolve Unattended Access application, a remote access tool digitally signed by GoTo Technologies USA, LLC. Despite its legitimate origin, the sample analyzed exhibits behaviors common to PUAs and potentially malicious software, including silent installation without user consent, execution of background threads to maintain persistent presence, and use of the Restart Manager library. The Restart Manager is notable because it is frequently leveraged by ransomware and wiper malware to manage system restarts during malicious operations, raising concerns about potential misuse. While no direct malicious payload or exploit has been observed in this sample, the remote access capabilities inherently present a significant security risk. Unauthorized actors could exploit these capabilities to gain control over affected systems, potentially deploying secondary malware or conducting further malicious activities. The detection by UltraAV antivirus solutions corroborates the classification of this software as a security threat. The threat does not have a CVSS score but is assessed as medium severity due to its persistence, stealthy installation, and remote access features. The threat is tagged with multiple MITRE ATT&CK techniques such as T1037 (Boot or Logon Initialization Scripts), T1543 (Create or Modify System Process), T1547 (Boot or Logon Autostart Execution), T1053 (Scheduled Task/Job), T1219 (Remote Access Software), T1204 (User Execution), T1559 (Inter-Process Communication), T1574 (Hijack Execution Flow), T1078 (Valid Accounts), and T1569 (System Services), indicating a broad range of potential tactics and techniques that could be leveraged for persistence and lateral movement. No known exploits in the wild have been reported, but the presence of unattended remote access capabilities necessitates caution. Organizations should evaluate the use of this software carefully, ensuring it is authorized and monitored within their security policies.

For European organizations, the presence of HEURRemoteAdmin.GoToResolve.gen can lead to unauthorized remote access, risking confidentiality, integrity, and availability of critical systems. The stealthy installation and persistence mechanisms increase the difficulty of detection and removal, potentially allowing threat actors to maintain long-term access. This could facilitate deployment of secondary malware such as ransomware or wipers, leading to data loss, operational disruption, and financial damage. The use of the Restart Manager library suggests potential for system manipulation during reboots, which could be exploited to evade defenses or cause system instability. Organizations in sectors with high reliance on remote access tools—such as finance, healthcare, manufacturing, and critical infrastructure—face elevated risks. Additionally, unauthorized remote access could lead to data breaches involving sensitive personal or corporate data, contravening GDPR and other regulatory requirements. The medium severity rating reflects the balance between the lack of direct malicious payload and the significant risk posed by the application's capabilities and behaviors.

1. Implement strict application whitelisting and control policies to prevent unauthorized installation of remote access tools like GoTo Resolve unless explicitly approved. 2. Monitor endpoints for silent installations and background processes associated with HEURRemoteAdmin.GoToResolve.gen indicators, including the listed file hashes. 3. Restrict and audit remote access permissions, ensuring only authorized personnel and systems have unattended access capabilities. 4. Employ behavioral monitoring to detect suspicious use of the Restart Manager library or unusual system restart activities. 5. Integrate detection rules in endpoint detection and response (EDR) solutions to flag persistence techniques such as scheduled tasks, service creation, and autostart modifications linked to this threat. 6. Conduct regular security awareness training to alert users about the risks of unauthorized remote access software and the importance of reporting unexpected installations. 7. Maintain up-to-date inventories of remote access software deployed within the organization and enforce strict change management. 8. Use network segmentation to limit the lateral movement potential if unauthorized access occurs. 9. Regularly review and update organizational policies regarding the use of remote administration tools to ensure alignment with security best practices and compliance requirements. 10. In case of detection, perform thorough incident response to assess potential secondary malware deployment and system compromise.
