Yara detected Telegram RAT
Yara detected AgentTesla
Yara detected AntiVM3
Sigma detected: Scheduled temp file as task from temp location
Multi AV Scanner detection for dropped file
Snort IDS alert for network traffic
Installs a global keyboard hook
Tries to steal Mail credentials (via file / registry access)
Initial sample is a PE file and has a suspicious name
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)
Uses the Telegram API (likely for C&C communication)
Contains functionality to register a low level keyboard hook
Machine Learning detection for sample
May check the online IP address of the machine
Injects a PE file into a foreign processes
.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
May sleep (evasive loops) to hinder dynamic analysis
Uses code obfuscation techniques (call, push, ret)
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
HTTP GET or POST without a user agent
IP address seen in connection with other malware
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)
Found inlined nop instructions (likely shell or obfuscated code)
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
Creates a window with clipboard capturing capabilities
Queries sensitive processor information (via WMI, Win32_Processor, often done to detect virtual machines)
Creates a process in suspended mode (likely to inject code)
