Signatures

Found malware configuration
Multi AV Scanner detection for submitted file
Malicious sample detected (through community Yara rule)
Sigma detected: NanoCore
Detected Nanocore Rat
Antivirus / Scanner detection for submitted sample
Sigma detected: Scheduled temp file as task from temp location
Antivirus detection for URL or domain
Antivirus detection for dropped file
Multi AV Scanner detection for dropped file
Yara detected Nanocore RAT
Connects to many ports of the same IP (likely port scanning)
Protects its processes via BreakOnTermination flag
Machine Learning detection for sample
.NET source code contains potential unpacker
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 schtasks.exe or at.exe to add and modify task schedules
Uses 32bit PE files
Yara signature match
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)
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)
Installs a raw input device (often for capturing keystrokes)
Sample file is different than original file name gathered from version info
Drops PE files
Contains functionality to open a port and listen for incoming connection (possibly a backdoor)
Detected TCP or UDP traffic on non-standard ports
Creates a process in suspended mode (likely to inject code)
