Signatures

Found malware configuration
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
Yara detected AgentTesla
Yara detected AntiVM3
Yara detected UAC Bypass using CMSTP
.NET source code references suspicious native API functions
Check if machine is in data center or colocation facility
Contains functionality to check if a debugger is running (CheckRemoteDebuggerPresent)
Contains functionality to log keystrokes (.Net Source)
Hides that the sample has been downloaded from the Internet (zone.identifier)
Injects a PE file into a foreign processes
Queries sensitive network adapter information (via WMI, Win32_NetworkAdapter, often done to detect virtual machines)
Queries sensitive video device information (via WMI, Win32_VideoController, often done to detect virtual machines)
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Tries to harvest and steal Putty / WinSCP information (sessions, passwords, etc)
Tries to harvest and steal browser information (history, passwords, etc)
Tries to harvest and steal ftp login credentials
Tries to steal Mail credentials (via file / registry access)
Writes to foreign memory regions
Yara detected Generic Downloader
AV process strings found (often used to terminate AV products)
Allocates memory with a write watch (potentially for evading sandboxes)
Binary contains a suspicious time stamp
Checks if the current process is being debugged
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Creates processes with suspicious names
Detected TCP or UDP traffic on non-standard ports
Detected potential crypto function
Drops PE files
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
May check the online IP address of the machine
May sleep (evasive loops) to hinder dynamic analysis
One or more processes crash
PE file does not import any functions
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, often done 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
Sigma detected: CurrentVersion Autorun Keys Modification
Sigma detected: Suspicious Outbound SMTP Connections
Uses SMTP (mail sending)
Uses code obfuscation techniques (call, push, ret)
Yara detected Credential Stealer
Yara signature match

Classification

Name Description Attribution Blogpost URLs Link
Agent Tesla, AgentTesla A .NET based information stealer readily available to actors due to leaked builders. The malware is able to log keystrokes, can access the host's clipboard and crawls the disk for credentials or other valuable information. It has the capability to send information back to its C&C via HTTP(S), SMTP, FTP, or towards a Telegram channel.
