Signatures
Found malware configuration
Multi AV Scanner detection for dropped file
Multi AV Scanner detection for submitted file
Yara detected AgentTesla
Adds a directory exclusion to Windows Defender
Changes security center settings (notifications, updates, antivirus, firewall)
Drops PE files with benign system names
Hides threads from debuggers
Machine Learning detection for dropped file
Machine Learning detection for sample
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, often done to detect virtual machines)
Queries sensitive network adapter information (via WMI, Win32_NetworkAdapter, often done to detect virtual machines)
Tries to delay execution (extensive OutputDebugStringW loop)
Binary contains a suspicious time stamp
Checks if Antivirus/Antispyware/Firewall program is installed (via WMI)
Checks if the current process is being debugged
Contains capabilities to detect virtual machines
Contains long sleeps (>= 3 min)
Creates a DirectInput object (often for capturing keystrokes)
Creates a process in suspended mode (likely to inject code)
Creates files inside the system directory
Detected potential crypto function
Dropped file seen in connection with other malware
Drops PE files
Enables debug privileges
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
HTTP GET or POST without a user agent
IP address seen in connection with other malware
JA3 SSL client fingerprint seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
One or more processes crash
PE file contains an invalid checksum
Queries disk information (often used to detect virtual machines)
Queries sensitive processor information (via WMI, Win32_Processor, often done to detect virtual machines)
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sample file is different than original file name gathered from version info
Tries to load missing DLLs
Uses code obfuscation techniques (call, push, ret)
Uses insecure TLS / SSL version for HTTPS connection
