General Information

Sample Name:G62PnhPS1s.exe
Analysis ID:714139


Range:0 - 100


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 dropped file
Multi AV Scanner detection for dropped file
Yara detected Nanocore RAT
Snort IDS alert for network traffic
Hides threads from debuggers
Tries to detect sandboxes and other dynamic analysis tools (window names)
Machine Learning detection for sample
.NET source code contains potential unpacker
PE file has nameless sections
Machine Learning detection for dropped file
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
Antivirus or Machine Learning detection for unpacked file
May sleep (evasive loops) to hinder dynamic analysis
Uses code obfuscation techniques (call, push, ret)
PE file contains sections with non-standard names
Internet Provider seen in connection with other malware
Detected potential crypto function
Found potential string decryption / allocating functions
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
Checks for debuggers (devices)
Creates a process in suspended mode (likely to inject code)
