Modifies the context of a thread in another process (thread injection)
Performs DNS queries to domains with low reputation
Renames NTDLL to bypass HIPS
Sets debug register (to hijack the execution of another thread)
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Tries to harvest and steal Putty / WinSCP information (sessions, passwords, etc)
Tries to harvest and steal browser information (history, passwords, etc)
Tries to steal Crypto Currency Wallets
Writes to foreign memory regions
Allocates memory with a write watch (potentially for evading sandboxes)
Antivirus or Machine Learning detection for unpacked file

Checks if the current process is being debugged
Connects to several IPs in different countries
Contains functionality to call native functions
Contains functionality to check if a debugger is running (IsDebuggerPresent)

Contains functionality to dynamically determine API calls
Contains functionality to query locales information (e.g. system language)
Contains functionality to read the PEB
Contains functionality which may be used to detect a debugger (GetProcessHeap)
Contains long sleeps (>= 3 min)
Creates a DirectInput object (often for capturing keystrokes)
Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
Downloads executable code via HTTP
Drops PE files
Drops PE files to the application program directory (C:\ProgramData)
Drops files with a non-matching file extension (content does not match file extension)
Enables debug privileges
Extensive use of GetProcAddress (often used to hide API calls)
Found dropped PE file which has not been started or loaded
Found inlined nop instructions (likely shell or obfuscated code)
Found potential string decryption / allocating functions
HTTP GET or POST without a user agent
IP address seen in connection with other malware
Installs a global mouse hook
Internet Provider seen in connection with other malware
Is looking for software installed on the system
JA3 SSL client fingerprint seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
PE file contains sections with non-standard names
PE file contains strange resources
Queries disk information (often used to detect virtual machines)
Queries information about the installed CPU (vendor, model number etc)
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sample file is different than original file name gathered from version info
Searches for user specific document files
Stores files to the Windows start menu directory
Tries to load missing DLLs
Uses 32bit PE files
Uses Microsoft's Enhanced Cryptographic Provider
Uses a known web browser user agent for HTTP communication
Uses code obfuscation techniques (call, push, ret)
