Yara detected AgentTesla
Found malware configuration
Multi AV Scanner detection for submitted file
Sigma detected: RegAsm connects to smtp port
Tries to detect Any.run
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Tries to steal Mail credentials (via file access)
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)
Hides threads from debuggers
Writes to foreign memory regions
Tries to harvest and steal Putty / WinSCP information (sessions, passwords, etc)
Tries to harvest and steal ftp login credentials
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, often done to detect virtual machines)
Very long cmdline option found, this is very uncommon (may be encrypted or packed)
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)
JA3 SSL client fingerprint seen in connection with other malware
Contains long sleeps (>= 3 min)
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
Drops files with a non-matching file extension (content does not match file extension)
PE file contains strange resources
Drops PE files
Tries to load missing DLLs
Uses a known web browser user agent for HTTP communication
Drops PE files to the windows directory (C:\Windows)
Checks if the current process is being debugged
Creates a process in suspended mode (likely to inject code)
Uses 32bit PE files
Queries the volume information (name, serial number etc) of a device
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Deletes files inside the Windows folder
Creates files inside the system directory
Internet Provider seen in connection with other malware
Contains functionality to query CPU information (cpuid)
Found potential string decryption / allocating functions
Yara detected Credential Stealer
Contains functionality to call native functions
Found dropped PE file which has not been started or loaded
Contains functionality which may be used to detect a debugger (GetProcessHeap)
Enables debug privileges
PE file does not import any functions
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)
Enables security privileges
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)
Uses Microsoft's Enhanced Cryptographic Provider
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
