Signatures
Found malware configuration
GuLoader behavior detected
Multi AV Scanner detection for submitted file
Yara detected GuLoader
C2 URLs / IPs found in malware configuration
Contains functionality to detect hardware virtualization (CPUID execution measurement)
Detected RDTSC dummy instruction sequence (likely for instruction hammering)
Hides threads from debuggers
Tries to detect Any.run
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Tries to detect virtualization through RDTSC time measurements
Tries to harvest and steal Putty / WinSCP information (sessions, passwords, etc)
Tries to harvest and steal browser information (history, passwords, etc)
Tries to harvest and steal ftp login credentials
Tries to steal Mail credentials (via file access)
Abnormal high CPU Usage
Checks if the current process is being debugged
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
Contains functionality to retrieve information about pressed keystrokes
Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
Enables debug privileges
IP address seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
Sample execution stops while process was sleeping (likely an evasion)
Sample file is different than original file name gathered from version info
Uses 32bit PE files
Uses a known web browser user agent for HTTP communication
Uses code obfuscation techniques (call, push, ret)
