Signatures

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)
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)

Yara signature match
Antivirus or Machine Learning detection for unpacked file
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)
Found evasive API chain (may stop execution after checking a module file name)
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
