Signatures

Detected Nanocore Rat
Found malware configuration
Malicious sample detected (through community Yara rule)
Sigma detected: NanoCore
Sigma detected: Scheduled temp file as task from temp location
Yara detected Nanocore RAT
.NET source code contains potential unpacker
Binary contains a suspicious time stamp
C2 URLs / IPs found in malware configuration
Hides that the sample has been downloaded from the Internet (zone.identifier)
Machine Learning detection for dropped file
Machine Learning detection for sample
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Uses dynamic DNS services
Uses schtasks.exe or at.exe to add and modify task schedules
Antivirus or Machine Learning detection for unpacked file
Contains capabilities to detect virtual machines
Contains long sleeps (>= 3 min)
Creates a DirectInput object (often for capturing keystrokes)
Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
Drops PE files
Enables debug privileges
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)
May sleep (evasive loops) to hinder dynamic analysis
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sample file is different than original file name gathered from version info
Tries to resolve domain names, but no domain seems valid (expired dropper behavior)
Uses 32bit PE files
Uses code obfuscation techniques (call, push, ret)
Yara signature match
