Found malware configuration
Multi AV Scanner detection for dropped file
Multi AV Scanner detection for submitted file
Yara detected Snake Keylogger
Adds a directory exclusion to Windows Defender
Changes security center settings (notifications, updates, antivirus, firewall)
Creates an autostart registry key pointing to binary in C:\Windows
Drops PE files with benign system names
Drops executables to the windows directory (C:\Windows) and starts them
Hides threads from debuggers
Injects a PE file into a foreign processes
Machine Learning detection for dropped file
Machine Learning detection for sample
May check the online IP address of the machine
Tries to delay execution (extensive OutputDebugStringW loop)
Tries to harvest and steal browser information (history, passwords, etc)
Tries to steal Mail credentials (via file access)
Yara detected Beds Obfuscator
Antivirus or Machine Learning detection for unpacked file
Binary contains a suspicious time stamp
Checks if Antivirus/Antispyware/Firewall program is installed (via WMI)
Checks if the current process is being debugged
Contains capabilities to detect virtual machines
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Creates files inside the system directory
Detected potential crypto function
Drops PE files
Drops PE files to the windows directory (C:\Windows)
Enables debug privileges
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
JA3 SSL client fingerprint seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
One or more processes crash
PE file contains an invalid checksum
Queries disk information (often used 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
Tries to load missing DLLs
Uses a known web browser user agent for HTTP communication
Uses code obfuscation techniques (call, push, ret)
Uses insecure TLS / SSL version for HTTPS connection
