AI-suggested
1. 2. If you cannot patch yet, restrict local access to developer machines running ReSharper by enforcing strict access controls and using endpoint protection solutions to detect suspicious privilege escalation attempts. 3. Implement application whitelisting and monitor for unauthorized modifications or executions related to ReSharper components. 4. Conduct regular audits of user privileges and remove unnecessary local accounts or permissions that could be leveraged by attackers. 5. Educate developers and IT staff about the risk of local privilege escalation vulnerabilities and encourage reporting of unusual system behavior. 6. Use host-based intrusion detection systems (HIDS) to monitor for anomalous activities indicative of privilege escalation attempts. 7. Consider isolating development environments or using virtual machines to limit the impact of potential compromises. 8. Maintain comprehensive logging and monitoring to facilitate rapid detection and response to exploitation attempts.
