Signatures

Multi AV Scanner detection for submitted file
Potential malicious icon found
Yara detected GuLoader
Contains functionality to detect hardware virtualization (CPUID execution measurement)
Contains functionality to hide a thread from the debugger
Found evasive API chain (may stop execution after reading information in the PEB, e.g. number of processors)
Hides threads from debuggers
Tries to detect virtualization through RDTSC time measurements
Contains capabilities to detect virtual machines
Contains functionality for execution timing, often used to detect debuggers
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
Contains functionality to call native functions
Contains functionality to read the PEB
Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
May sleep (evasive loops) to hinder dynamic analysis
PE file contains strange resources
Sample execution stops while process was sleeping (likely an evasion)
Sample file is different than original file name gathered from version info
Uses code obfuscation techniques (call, push, ret)
