Signatures
Multi AV Scanner detection for submitted file
Yara detected Credential Flusher
AI detected suspicious sample
Binary is likely a compiled AutoIt script file
Found API chain indicative of sandbox detection
Machine Learning detection for sample
Connects to many different domains
Contains functionality for execution timing, often used to detect debuggers
Contains functionality for read data from the clipboard
Contains functionality to block mouse and keyboard input (often used to hinder debugging)
Contains functionality to call native functions
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to check if a window is minimized (may be used to check if an application is visible)
Contains functionality to communicate with device drivers
Contains functionality to dynamically determine API calls
Contains functionality to execute programs as a different user
Contains functionality to launch a process as a different user
Contains functionality to launch a program with higher privileges
Contains functionality to modify clipboard data
Contains functionality to open a port and listen for incoming connection (possibly a backdoor)
Contains functionality to query CPU information (cpuid)
Contains functionality to read the PEB
Contains functionality to read the clipboard data
Contains functionality to retrieve information about pressed keystrokes
Contains functionality to shutdown / reboot the system
Contains functionality to simulate keystroke presses
Contains functionality to simulate mouse events
Contains functionality which may be used to detect a debugger (GetProcessHeap)
Detected potential crypto function
Drops PE files
Enables debug privileges
Found large amount of non-executed APIs
Found potential string decryption / allocating functions
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
OS version to string mapping found (often used in BOTs)
PE file contains sections with non-standard names
Potential key logger detected (key state polling based)
Sample execution stops while process was sleeping (likely an evasion)
Suricata IDS alerts with low severity for network traffic
Uses 32bit PE files
Uses code obfuscation techniques (call, push, ret)
Uses taskkill to terminate processes
