An analyst is reviewing system logs while threat hunting:Which of the following hosts should be...

From the logs, PC3 showsoutlook.exe spawning excel.exe at 1:15 PM, and laterexcel.exe spawning procdump.exe at 1:16 PM. This is highly suspicious becauseoutlook.exe should not normally launch Excel, andprocdump.exe is often used by attackers to dump process memory, which is a common technique in credential theft​.

PC1:Running expected Windows processes (wininit.exe spawning services.exe and lsass.exe).

PC2:Running a browser process (chrome.exe) from explorer.exe, which is normal.

PC3:Highly suspicious behavior (Excel spawning procdump.exe).

PC4:Running mstsc.exe (Remote Desktop) from explorer.exe, which is expected.

PC5:Running Firefox from explorer.exe, which is normal.

Thus,PC3 should be prioritized for investigationdue to its potential involvement in credential theft.
