Range:0 - 100
Whitelisted:false
Confidence:100%

Signatures

Found malware configuration
Snort IDS alert for network traffic (e.g. based on Emerging Threat rules)
Multi AV Scanner detection for submitted file
Malicious sample detected (through community Yara rule)
Sigma detected: NanoCore
Yara detected AntiVM3
Detected Nanocore Rat
Multi AV Scanner detection for domain / URL
Multi AV Scanner detection for dropped file
Yara detected Nanocore RAT
Initial sample is a PE file and has a suspicious name
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Sigma detected: Suspicius Add Task From User AppData Temp
.NET source code contains potential unpacker
Injects a PE file into a foreign processes
Sigma detected: Powershell Defender Exclusion
C2 URLs / IPs found in malware configuration
Adds a directory exclusion to Windows Defender
Hides that the sample has been downloaded from the Internet (zone.identifier)
Uses schtasks.exe or at.exe to add and modify task schedules
Uses dynamic DNS services
Uses 32bit PE files
Queries the volume information (name, serial number etc) of a device
Yara signature match
Antivirus or Machine Learning detection for unpacked file
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)
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)
Contains functionality to call native functions
IP address seen in connection with other malware
Contains long sleeps (>= 3 min)
Enables debug privileges
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)
Found inlined nop instructions (likely shell or obfuscated code)
Installs a raw input device (often for capturing keystrokes)
Sample file is different than original file name gathered from version info
Drops PE files
Tries to load missing DLLs
Detected TCP or UDP traffic on non-standard ports
Contains capabilities to detect virtual machines
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
Creates a process in suspended mode (likely to inject code)
