Signatures

Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
Yara detected FormBook
AI detected suspicious sample
Binary is likely a compiled AutoIt script file
Found API chain indicative of sandbox detection
Found direct / indirect Syscall (likely to bypass EDR)
Initial sample is a PE file and has a suspicious name
Machine Learning detection for sample
Maps a DLL or memory area into another process
Modifies the context of a thread in another process (thread injection)
Queues an APC in another process (thread injection)
Switches to a custom stack to bypass stack traces
Tries to harvest and steal browser information (history, passwords, etc)
Tries to steal Mail credentials (via file / registry access)
Writes to foreign memory regions
Checks if the current process is being debugged
Contains functionality for execution timing, often used to detect debuggers
Contains functionality for read data from the clipboard
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
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 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)
Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
Found inlined nop instructions (likely shell or obfuscated code)
Found large amount of non-executed APIs
Found potential string decryption / allocating functions
IP address seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
OS version to string mapping found (often used in BOTs)
Potential key logger detected (key state polling based)
Sample execution stops while process was sleeping (likely an evasion)
Sample file is different than original file name gathered from version info
Sigma detected: Uncommon Svchost Parent Process
Uses 32bit PE files
Uses code obfuscation techniques (call, push, ret)
Yara signature match
