Multi AV Scanner detection for dropped file
Multi AV Scanner detection for submitted file
Suricata IDS alerts for network traffic
AI detected suspicious sample
Contains functionality to check if Internet connection is working
Contains functionality to detect sleep reduction / modifications
Drops executables to the windows directory (C:\Windows) and starts them
Found evasive API chain (may stop execution after checking mutex)
Hides that the sample has been downloaded from the Internet (zone.identifier)
Machine Learning detection for dropped file
Machine Learning detection for sample
Uses schtasks.exe or at.exe to add and modify task schedules
Allocates memory with a write watch (potentially for evading sandboxes)
Contains functionality for read data from the clipboard
Contains functionality to call native functions
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to modify clipboard data
Contains functionality to open a port and listen for incoming connection (possibly a backdoor)
Contains functionality to query locales information (e.g. system language)
Contains functionality to read the clipboard data
Contains functionality which may be used to detect a debugger (GetProcessHeap)
Contains long sleeps (>= 3 min)

Found large amount of non-executed APIs
IP address seen in connection with other malware
Installs a raw input device (often for capturing keystrokes)
Internet Provider seen in connection with other malware
May check if the current machine is a sandbox (GetTickCount - Sleep)
May sleep (evasive loops) to hinder dynamic analysis
PE file does not import any functions
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sigma detected: Wow6432Node CurrentVersion Autorun Keys Modification
Suricata IDS alerts with low severity for network traffic
