Detection

AgentTesla
Score:100
Range:0 - 100
Whitelisted:false
Confidence:100%

Signatures

Multi AV Scanner detection for submitted file
Malicious sample detected (through community Yara rule)
Yara detected AgentTesla
Yara detected AntiVM3
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
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
Contains long sleeps (>= 3 min)
Enables debug privileges
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
Detected TCP or UDP traffic on non-standard ports
Uses SMTP (mail sending)
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)
