Sigma detected: Copying Sensitive Files with Credential Data
Maps a DLL or memory area into another process
Found evasive API chain (may stop execution after checking mutex)
PE file has a writeable .text section
Injects a PE file into a foreign processes
Found evasive API chain (may stop execution after checking locale)
Deletes itself after installation
Creates a thread in another existing process (thread injection)
Hides that the sample has been downloaded from the Internet (zone.identifier)
Found many strings related to Crypto-Wallets (likely being stolen)
Checks if the current machine is a virtual machine (disk enumeration)
Sample uses process hollowing technique
.NET source code references suspicious native API functions
Changes security center settings (notifications, updates, antivirus, firewall)
Found evasive API chain (may stop execution after reading information in the PEB, e.g. number of processors)

.NET source code contains method to dynamically call methods (often used by packers)
Machine Learning detection for dropped file
C2 URLs / IPs found in malware configuration
Contains functionality to detect sleep reduction / modifications
Found evasive API chain (may stop execution after checking computer name)
Antivirus or Machine Learning detection for unpacked file
Contains functionality to query locales information (e.g. system language)
May sleep (evasive loops) to hinder dynamic analysis
Checks if Antivirus/Antispyware/Firewall program is installed (via WMI)
Uses code obfuscation techniques (call, push, ret)
Detected potential crypto function
Sample execution stops while process was sleeping (likely an evasion)
JA3 SSL client fingerprint seen in connection with other malware
Contains functionality to dynamically determine API calls
Downloads executable code via HTTP
Contains long sleeps (>= 3 min)
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)

PE file contains strange resources
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
Binary contains a suspicious time stamp
Dropped file seen in connection with other malware
Found large amount of non-executed APIs
Connects to a URL shortener service
May check if the current machine is a sandbox (GetTickCount - Sleep)
Creates a process in suspended mode (likely to inject code)
Uses 32bit PE files
Queries the volume information (name, serial number etc) of a device
Creates files inside the system directory
PE file contains sections with non-standard names

PE file contains executable resources (Code or Archives)
IP address seen in connection with other malware
Creates a DirectInput object (often for capturing keystrokes)
AV process strings found (often used to terminate AV products)
Extensive use of GetProcAddress (often used to hide API calls)
Detected TCP or UDP traffic on non-standard ports
Found evaded block containing many API calls
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
Uses Microsoft's Enhanced Cryptographic Provider
