Signatures

Yara detected RedLine Stealer
Detected unpacking (overwrites its own PE header)
Yara detected AntiVM3
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
Yara detected RHADAMANTHYS Stealer
Benign windows process drops PE files
Malicious sample detected (through community Yara rule)
Yara detected Djvu Ransomware
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
Allocates memory in foreign processes
Injects a PE file into a foreign processes
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)
Checks if the current machine is a virtual machine (disk enumeration)
Hides threads from debuggers
Writes to foreign memory regions
Checks for kernel code integrity (NtQuerySystemInformation(CodeIntegrityInformation))
Machine Learning detection for dropped file
C2 URLs / IPs found in malware configuration
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, often done to detect virtual machines)
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)
Found evasive API chain (date check)
Detected potential crypto function
Sample execution stops while process was sleeping (likely an evasion)
Found evasive API chain (may stop execution after checking a module file name)
JA3 SSL client fingerprint seen in connection with other malware
Contains functionality to dynamically determine API calls
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
Yara detected Keylogger Generic
Dropped file seen in connection with other malware
Creates a process in suspended mode (likely to inject code)
Queries sensitive Operating System Information (via WMI, Win32_ComputerSystem, often done to detect virtual machines)
Contains functionality for read data from the clipboard
Uses 32bit PE files
Queries the volume information (name, serial number etc) of a device
Yara signature match
Contains functionality to check if a debugger is running (IsDebuggerPresent)
PE file contains sections with non-standard names
Internet Provider seen in connection with other malware
Contains functionality to query CPU information (cpuid)
Found potential string decryption / allocating functions
Contains functionality to call native functions
Contains functionality to read the clipboard data
Found dropped PE file which has not been started or loaded
Contains functionality which may be used to detect a debugger (GetProcessHeap)
IP address seen in connection with other malware
Creates a DirectInput object (often for capturing keystrokes)
Installs a raw input device (often for capturing keystrokes)
Allocates memory with a write watch (potentially for evading sandboxes)
Detected TCP or UDP traffic on non-standard ports
Queries sensitive processor information (via WMI, Win32_Processor, often done to detect virtual machines)
