Detection:
malicious
Classification:
evad
Score:
92 / 100
Signature
Executable has a suspicious name (potential lure to open the executable)
Found evasive API chain (may stop execution after reading information in the PEB, e.g. number of processors)
Initial sample is a PE file and has a suspicious name
Injects a PE file into a foreign processes
Machine Learning detection for sample
Multi AV Scanner detection for dropped file
Multi AV Scanner detection for submitted file
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, often done to detect virtual machines)
Queries sensitive network adapter information (via WMI, Win32_NetworkAdapter, often done to detect virtual machines)
