Malicious sample detected (through community Yara rule)
Yara detected AgentTesla
Antivirus / Scanner detection for submitted sample
Tries to steal Mail credentials (via file / registry access)
Writes to foreign memory regions
.NET source code references suspicious native API functions
Machine Learning detection for sample
Allocates memory in foreign processes
Injects a PE file into a foreign processes
.NET source code contains very large array initializations
Queries sensitive network adapter information (via WMI, Win32_NetworkAdapter, often done to detect virtual machines)
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)
Detected potential crypto function
Yara detected Credential Stealer
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
PE file contains an invalid checksum
Detected TCP or UDP traffic on non-standard ports
Uses SMTP (mail sending)
PE / OLE file has an invalid certificate
Queries sensitive processor information (via WMI, Win32_Processor, often done to detect virtual machines)
