Analysis ID:712259


Range:0 - 100


Malicious sample detected (through community Yara rule)
Sigma detected: NanoCore
Detected Nanocore Rat
Antivirus detection for URL or domain
Yara detected Nanocore RAT
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Yara detected Costura Assembly Loader
Encrypted powershell cmdline option found
Machine Learning detection for sample
.NET source code contains potential unpacker
Injects a PE file into a foreign processes
Machine Learning detection for dropped file
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
Uses code obfuscation techniques (call, push, ret)
Internet Provider seen in connection with other malware
Detected potential crypto function
Sample execution stops while process was sleeping (likely an evasion)
JA3 SSL client fingerprint seen in connection with other malware
HTTP GET or POST without a user agent
IP address seen in connection with other malware
Contains long sleeps (>= 3 min)
Enables debug privileges
Creates a DirectInput object (often for capturing keystrokes)

Installs a raw input device (often for capturing keystrokes)
Sample file is different than original file name gathered from version info
Drops PE files
Detected TCP or UDP traffic on non-standard ports
