Detection

Nanocore
Score:100
Range:0 - 100
Whitelisted:false
Confidence:100%

Signatures

Multi AV Scanner detection for submitted file
Malicious sample detected (through community Yara rule)
Detected unpacking (overwrites its own PE header)
Sigma detected: NanoCore
Yara detected AntiVM3
Detected Nanocore Rat
Detected unpacking (changes PE section rights)
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
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
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
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 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 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)
Found inlined nop instructions (likely shell or obfuscated code)
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
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
Creates a process in suspended mode (likely to inject code)
