Detection

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

Signatures

Found malware configuration
Multi AV Scanner detection for submitted file
Malicious sample detected (through community Yara rule)
Sigma detected: NanoCore
Yara detected AntiVM3
Detected Nanocore Rat
Antivirus detection for URL or domain
Yara detected Nanocore RAT
Snort IDS alert for network traffic
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)
.NET source code contains potential unpacker
C2 URLs / IPs found in malware configuration
Hides that the sample has been downloaded from the Internet (zone.identifier)
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
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)
Installs a raw input device (often for capturing keystrokes)
Sample file is different than original file name gathered from version info
Detected TCP or UDP traffic on non-standard ports
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
Creates a process in suspended mode (likely to inject code)
