Signatures
Found malware configuration
Multi AV Scanner detection for submitted file
Yara detected AgentTesla
Installs a global keyboard hook
Tries to steal Mail credentials (via file / registry access)
Initial sample is a PE file and has a suspicious name
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Yara detected Costura Assembly Loader
Contains functionality to log keystrokes (.Net Source)
Machine Learning detection for sample
May check the online IP address of the machine
.NET source code contains potential unpacker
Injects a PE file into a foreign processes
Queries sensitive network adapter information (via WMI, Win32_NetworkAdapter, often done to detect virtual machines)
Sample uses string decryption to hide its real strings
Tries to harvest and steal browser information (history, passwords, etc)
Uses 32bit PE files
Queries the volume information (name, serial number etc) of a device
May sleep (evasive loops) to hinder dynamic analysis
Uses code obfuscation techniques (call, push, ret)
Detected potential crypto function
Yara detected Credential Stealer
Contains long sleeps (>= 3 min)
Enables debug privileges
Creates a DirectInput object (often for capturing keystrokes)
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
Sample file is different than original file name gathered from version info
Uses a known web browser user agent for HTTP communication
Creates a window with clipboard capturing capabilities
Queries sensitive processor information (via WMI, Win32_Processor, often done to detect virtual machines)
Creates a process in suspended mode (likely to inject code)
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, often done to detect virtual machines)
