Signature
.NET source code contains method to dynamically call methods (often used by packers)
.NET source code references suspicious native API functions
Antivirus detection for URL or domain
Benign windows process drops PE files
C2 URLs / IPs found in malware configuration
Checks for kernel code integrity (NtQuerySystemInformation(CodeIntegrityInformation))
Checks if the current machine is a virtual machine (disk enumeration)
Connects to many ports of the same IP (likely port scanning)
Contains functionality to infect the boot sector
Creates a thread in another existing process (thread injection)
Deletes itself after installation
Detected unpacking (changes PE section rights)
Detected unpacking (overwrites its own PE header)
Found malware configuration
Hides that the sample has been downloaded from the Internet (zone.identifier)
Hides threads from debuggers
Machine Learning detection for dropped file
Machine Learning detection for sample
Maps a DLL or memory area into another process
Multi AV Scanner detection for dropped file
Multi AV Scanner detection for submitted file
PE file has nameless sections
Queries sensitive disk information (via WMI, Win32_DiskDrive, often done to detect virtual machines)
Queries sensitive video device information (via WMI, Win32_VideoController, often done to detect virtual machines)
Query firmware table information (likely to detect VMs)
System process connects to network (likely due to code injection or exploit)
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Tries to detect sandboxes and other dynamic analysis tools (window names)
Tries to evade analysis by execution special instruction which cause usermode exception
Tries to harvest and steal browser information (history, passwords, etc)
