Signatures

Multi AV Scanner detection for submitted file
Yara detected Ursnif
Contains functionality to call native functions
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to dynamically determine API calls
Contains functionality to open a port and listen for incoming connection (possibly a backdoor)
Contains functionality to query CPU information (cpuid)
Contains functionality to query locales information (e.g. system language)
Contains functionality to read the PEB
Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
Found potential string decryption / allocating functions
PE file contains an invalid checksum
Program does not show much activity (idle)
Sample execution stops while process was sleeping (likely an evasion)
Uses 32bit PE files
Uses code obfuscation techniques (call, push, ret)
