Signatures

Malicious sample detected (through community Yara rule)
Yara detected AgentTesla
Yara detected AntiVM3
Sigma detected: Scheduled temp file as task from temp location
Snort IDS alert for network traffic
Installs a global keyboard hook
Tries to steal Mail credentials (via file / registry access)
Tries to harvest and steal Putty / WinSCP information (sessions, passwords, etc)
Tries to harvest and steal ftp login credentials
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
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
.NET source code contains method to dynamically call methods (often used by packers)
.NET source code contains very large array initializations
Machine Learning detection for dropped file
Queries sensitive network adapter information (via WMI, Win32_NetworkAdapter, often done to detect virtual machines)
Uses schtasks.exe or at.exe to add and modify task schedules
Tries to harvest and steal browser information (history, passwords, etc)
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, often done to detect virtual machines)
Uses 32bit PE files
Queries the volume information (name, serial number etc) of a device
Yara signature match
Antivirus or Machine Learning detection for unpacked file
May sleep (evasive loops) to hinder dynamic analysis
Uses code obfuscation techniques (call, push, ret)
Internet Provider seen in connection with other malware
Detected potential crypto function
Sample execution stops while process was sleeping (likely an evasion)
Yara detected Credential Stealer
JA3 SSL client fingerprint seen in connection with other malware
IP address seen in connection with other malware
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
Drops PE files
Uses a known web browser user agent for HTTP communication
Detected TCP or UDP traffic on non-standard ports
Uses SMTP (mail sending)
Creates a window with clipboard capturing capabilities
Queries sensitive processor information (via WMI, Win32_Processor, often done to detect virtual machines)
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
Creates a process in suspended mode (likely to inject code)
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
