Signatures
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
Yara detected GhostRat
AI detected suspicious sample
Found direct / indirect Syscall (likely to bypass EDR)
Loading BitLocker PowerShell Module
Machine Learning detection for dropped file
Machine Learning detection for sample
Reads the Security eventlog
Reads the System eventlog
AV process strings found (often used to terminate AV products)
Allocates memory with a write watch (potentially for evading sandboxes)
Checks for available system drives (often done to infect USB drives)
Checks if the current process is being debugged
Contains capabilities to detect virtual machines
Contains functionality to call native functions
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to check if a debugger is running (OutputDebugString,GetLastError)
Contains functionality to dynamically determine API calls
Contains functionality to get notified if a device is plugged in / out
Contains functionality to query CPU information (cpuid)
Contains functionality which may be used to detect a debugger (GetProcessHeap)
Contains long sleeps (>= 3 min)
Creates a DirectInput object (often for capturing keystrokes)
Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
Drops PE files
Enables debug privileges

One or more processes crash
PE file contains sections with non-standard names
PE file does not import any functions
Queries information about the installed CPU (vendor, model number etc)
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
Sigma detected: PSScriptPolicyTest Creation By Uncommon Process
Suricata IDS alerts with low severity for network traffic
Uses code obfuscation techniques (call, push, ret)
