General Information

Sample Name:e1f388b8a086e034b1fbd94ca7341008.exe
Analysis ID:623326


Range:0 - 100


Found malware configuration
Multi AV Scanner detection for submitted file
Malicious sample detected (through community Yara rule)
Sigma detected: NanoCore
Yara detected AntiVM3
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
Snort IDS alert for network traffic
Connects to many ports of the same IP (likely port scanning)
.NET source code references suspicious native API functions
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
.NET source code contains potential unpacker
Injects a PE file into a foreign processes
C2 URLs / IPs found in malware configuration
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)
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
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
PE file contains strange resources
Drops PE files
Detected TCP or UDP traffic on non-standard ports
Creates a process in suspended mode (likely to inject code)
