Signatures
Found malware configuration
Multi AV Scanner detection for submitted file
Benign windows process drops PE files
Yara detected SmokeLoader
System process connects to network (likely due to code injection or exploit)
Antivirus detection for URL or domain
Multi AV Scanner detection for domain / URL
Multi AV Scanner detection for dropped file
Maps a DLL or memory area into another process
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Machine Learning detection for sample
Checks for kernel code integrity (NtQuerySystemInformation(CodeIntegrityInformation))
Deletes itself after installation
Machine Learning detection for dropped file
C2 URLs / IPs found in malware configuration
Creates a thread in another existing process (thread injection)
Hides that the sample has been downloaded from the Internet (zone.identifier)
Checks if the current machine is a virtual machine (disk enumeration)
Uses 32bit PE files
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to query locales information (e.g. system language)
May sleep (evasive loops) to hinder dynamic analysis
Uses code obfuscation techniques (call, push, ret)
PE file contains sections with non-standard names
Internet Provider seen in connection with other malware
Detected potential crypto function
Found potential string decryption / allocating functions
Sample execution stops while process was sleeping (likely an evasion)
Contains functionality to call native functions
Contains functionality to dynamically determine API calls
Contains functionality which may be used to detect a debugger (GetProcessHeap)
IP address seen in connection with other malware
Downloads executable code via HTTP
Creates a DirectInput object (often for capturing keystrokes)
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
