Signatures
Antivirus detection for URL or domain
Antivirus detection for dropped file
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for dropped file
Multi AV Scanner detection for submitted file
Suricata IDS alerts for network traffic
System process connects to network (likely due to code injection or exploit)
VBScript performs obfuscated calls to suspicious functions
Yara detected FormBook
Found direct / indirect Syscall (likely to bypass EDR)
Found suspicious powershell code related to unpacking or dynamic code loading
Joe Sandbox ML detected suspicious sample
Machine Learning detection for dropped file
Maps a DLL or memory area into another process
Modifies the context of a thread in another process (thread injection)
PE file contains section with special chars
Performs DNS queries to domains with low reputation
Powershell drops PE file
Sigma detected: Script Initiated Connection to Non-Local Network
Sigma detected: WScript or CScript Dropper
Suspicious execution chain found
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)
Windows Scripting host queries suspicious COM object (likely to drop second stage)
Wscript starts Powershell (via cmd or directly)
Allocates memory with a write watch (potentially for evading sandboxes)
Checks if the current process is being debugged
Contains functionality for execution timing, often used to detect debuggers
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
Contains functionality to call native functions
Contains functionality to read the PEB
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
Downloads executable code via HTTP
Drops PE files
Found WSH timer for Javascript or VBS script (likely evasive script)
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
Found inlined nop instructions (likely shell or obfuscated code)
Found large amount of non-executed APIs
Found potential string decryption / allocating functions
HTTP GET or POST without a user agent
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
Java / VBScript file with very long strings (likely obfuscated code)
May sleep (evasive loops) to hinder dynamic analysis
PE file contains sections with non-standard names
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: Script Initiated Connection
Sigma detected: WSF/JSE/JS/VBA/VBE File Execution Via Cscript/Wscript
Uses code obfuscation techniques (call, push, ret)
Yara signature match
