Signatures

Multi AV Scanner detection for submitted file
Malicious sample detected (through community Yara rule)
Sigma detected: NanoCore
Yara detected AntiVM3
Detected Nanocore Rat
Multi AV Scanner detection for dropped file
Yara detected Nanocore RAT
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Sigma detected: Suspicius Add Task From User AppData Temp
Injects a PE file into a foreign processes
Sigma detected: Powershell Defender Exclusion
Adds a directory exclusion to Windows Defender
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 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)
Detected potential crypto function
Sample execution stops while process was sleeping (likely an evasion)
Contains functionality to call native functions
Contains long sleeps (>= 3 min)
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)
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)
