Robocopy.exe is not malicious; it is a legitimate and powerful command-line file copy tool built into Microsoft Windows. However, like many system utilities, its powerful functionality can be misused.
🔍 How to Verify the Legitimacy of Robocopy.exe
Since malware can sometimes disguise itself with the same filename, you can perform these quick checks to ensure the robocopy.exe on your computer is genuine:
| Check | What to Look For |
|---|---|
| File Location | The legitimate file is typically in C:\Windows\System32 or C:\Windows\SysWOW64. |
| Digital Signature | Check the file’s properties to confirm it is signed by Microsoft Corporation. |
| Antivirus Scan | Perform a scan with your security software if the file is in an unusual location or you notice system issues. |
⚠️ A Note on Potential for Misuse
While robocopy.exe itself is safe, its powerful capabilities for copying, moving, and synchronizing large amounts of data make it a tool that can be repurposed for malicious activities, such as lateral movement across a network or exfiltrating data. This is why some security monitoring tools may flag its usage in specific, unusual contexts.
I hope this information helps you feel more secure. If you’d like to know how to check the file’s digital signature, just let me know

Scenario: a hacker uses remote access to run robocopy in the background of your device. Is there anyway, after the fact, to find out more info on what they copied/transferred?
Thanks.
After a remote attacker uses Robocopy, evidence depends on speed and logging. Immediately check Windows Event Logs (PowerShell/Security) for process creation events, which may show the command used. Forensic analysis of the NTFS USN Journal can reveal precisely which files were accessed and copied, though this data gets overwritten. Sysmon or EDR logs, if present, are invaluable. Examine any leftover Robocopy log files and look for large outbound network transfers in firewall logs. Without prior detailed auditing, full reconstruction is difficult, especially if the attacker cleared logs. The best chance lies in combining file system forensics with any available process or network telemetry.
