Signatures

Found malware configuration
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for dropped file
Multi AV Scanner detection for submitted file
Sigma detected: NanoCore
Yara detected AntiVM3
Yara detected Nanocore RAT
Allocates memory in foreign processes
C2 URLs / IPs found in malware configuration
Hides that the sample has been downloaded from the Internet (zone.identifier)
Injects a PE file into a foreign processes
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Uses schtasks.exe or at.exe to add and modify task schedules
Writes to foreign memory regions
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 TCP or UDP traffic on non-standard ports
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)
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
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 load missing DLLs
Uses 32bit PE files
Uses code obfuscation techniques (call, push, ret)
Yara signature match
