Signatures
Antivirus detection for dropped file
Benign windows process drops PE files
Malicious sample detected (through community Yara rule)
Suricata IDS alerts for network traffic
Yara detected FormBook
.NET source code contains method to dynamically call methods (often used by packers)
.NET source code references suspicious native API functions
AI detected suspicious sample
Allocates memory in foreign processes
Found direct / indirect Syscall (likely to bypass EDR)
Injects a PE file into a foreign processes
Machine Learning detection for dropped file
Maps a DLL or memory area into another process
Performs DNS queries to domains with low reputation
Potential evasive VBS script found (sleep loop)
Queues an APC in another process (thread injection)
Sigma detected: WScript or CScript Dropper
Suspicious execution chain found
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)
Writes to foreign memory regions
Allocates memory with a write watch (potentially for evading sandboxes)
Allocates memory within range which is reserved for system DLLs (kernel32.dll, advapi32.dll, etc)
Binary contains a suspicious time stamp
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 open a port and listen for incoming connection (possibly a backdoor)
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
Dropped file seen in connection with other malware
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 dropped PE file which has not been started or loaded
Found large amount of non-executed APIs
Found potential string decryption / allocating functions
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 more sections than normal
PE file contains sections with non-standard names
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Searches the installation path of Mozilla Firefox
Sigma detected: WSF/JSE/JS/VBA/VBE File Execution Via Cscript/Wscript
Uses code obfuscation techniques (call, push, ret)
Yara signature match
