Signatures
.NET source code contains very large strings
Sample is not signed and drops a device driver
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Adds / modifies Windows certificates
Allocates memory with a write watch (potentially for evading sandboxes)
Binary contains a suspicious time stamp
Checks for available system drives (often done to infect USB drives)
Creates a process in suspended mode (likely to inject code)
Creates driver files
Creates files inside the system directory
Deletes files inside the Windows folder
Drops PE files
Drops PE files to the windows directory (C:\Windows)
Drops files with a non-matching file extension (content does not match file extension)
Found dropped PE file which has not been started or loaded
Found inlined nop instructions (likely shell or obfuscated code)
PE file contains an invalid checksum
PE file contains sections with non-standard names
PE file does not import any functions
Queries the volume information (name, serial number etc) of a device
Sample file is different than original file name gathered from version info
Uses cacls to modify the permissions of files
Uses code obfuscation techniques (call, push, ret)
Classification
Analysis Advice
Sample drops PE files which have not been started, submit dropped PE samples for a secondary analysis to Joe Sandbox |
Sample is looking for USB drives. Launch the sample with the USB Fake Disk cookbook |
Sample tries to load a library which is not present or installed on the analysis machine, adding the library might reveal more behavior |
