Signatures

Multi AV Scanner detection for submitted file
Benign windows process drops PE files
Malicious sample detected (through community Yara rule)
Yara detected SmokeLoader
System process connects to network (likely due to code injection or exploit)
Detected unpacking (changes PE section rights)
Antivirus detection for URL or domain
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
Yara signature match
May sleep (evasive loops) to hinder dynamic analysis
Uses code obfuscation techniques (call, push, ret)
Internet Provider seen in connection with other malware
Sample execution stops while process was sleeping (likely an evasion)
Contains functionality to call native functions
PE file contains executable resources (Code or Archives)
IP address seen in connection with other malware
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)
Drops files with a non-matching file extension (content does not match file extension)
Drops PE files
Tries to load missing DLLs
Contains functionality to read the PEB
Uses a known web browser user agent for HTTP communication
Checks if the current process is being debugged
