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)
Sigma detected: NanoCore
Detected Nanocore Rat
Antivirus detection for URL or domain
Multi AV Scanner detection for domain / URL
Multi AV Scanner detection for dropped file
Yara detected Nanocore RAT
Initial sample is a PE file and has a suspicious name
Connects to many ports of the same IP (likely port scanning)
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Yara detected Costura Assembly Loader
Encrypted powershell cmdline option found
Machine Learning detection for sample
.NET source code contains potential unpacker
Injects a PE file into a foreign processes
.NET source code contains very large array initializations
Machine Learning detection for dropped file
C2 URLs / IPs found in malware configuration
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)
Internet Provider seen in connection with other malware
Detected potential crypto function
Sample execution stops while process was sleeping (likely an evasion)
IP address seen in connection with other malware
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
Detected TCP or UDP traffic on non-standard ports
Binary contains a suspicious time stamp
Creates a process in suspended mode (likely to inject code)
