Remediation Steps:
Isolate the endpoint from the network immediately. Use Windows Defender or another endpoint security solution to perform a full scan and remove the threat. Manually inspect and remove suspicious scheduled tasks, BITS jobs, and startup entries. Due to the high risk of compromise, a full system reimage is strongly recommended.
