Signatures

Multi AV Scanner detection for submitted file
Icon mismatch, binary includes an icon from a different legit application in order to fool users
Malicious sample detected (through community Yara rule)
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
Installs a global keyboard hook
Tries to steal Mail credentials (via file / registry access)
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Machine Learning detection for sample
.NET source code contains very large array initializations
Machine Learning detection for dropped file
Adds a directory exclusion to Windows Defender
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
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
Sample execution stops while process was sleeping (likely an evasion)
Yara detected Credential Stealer
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
Drops PE files
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)
