Signatures
Antivirus detection for URL or domain
Detected Nanocore Rat
Found malware configuration
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for domain / URL
Multi AV Scanner detection for dropped file
Sigma detected: EQNEDT32.EXE connecting to internet
Sigma detected: File Dropped By EQNEDT32EXE
Sigma detected: NanoCore
Sigma detected: Scheduled temp file as task from temp location
Snort IDS alert for network traffic (e.g. based on Emerging Threat rules)
Yara detected AntiVM3
Yara detected Nanocore RAT
Allocates memory in foreign processes
C2 URLs / IPs found in malware configuration
Drops PE files to the user root directory
Hides that the sample has been downloaded from the Internet (zone.identifier)
Injects a PE file into a foreign processes
Machine Learning detection for dropped file
Office equation editor drops PE file
Office equation editor starts processes (likely CVE 2017-11882 or CVE-2018-0802)
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Uses schtasks.exe or at.exe to add and modify task schedules
Writes to foreign memory regions
Allocates a big amount of memory (probably used for heap spraying)
Allocates memory within range which is reserved for system DLLs (kernel32.dll, advapi32.dll, etc)
Antivirus or Machine Learning detection for unpacked file
Contains functionality to call native functions
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Detected TCP or UDP traffic on non-standard ports
Detected potential crypto function
Document misses a certain OLE stream usually present in this Microsoft Office document type
Downloads executable code via HTTP
Dropped file seen in connection with other malware
Drops PE files
Drops PE files to the user directory
Enables debug privileges
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)
IP address seen in connection with other malware
Installs a raw input device (often for capturing keystrokes)
Internet Provider seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
Office Equation Editor has been started
Potential document exploit detected (performs DNS queries)
Potential document exploit detected (performs HTTP gets)
Potential document exploit detected (unknown TCP traffic)
Queries the volume information (name, serial number etc) of a device
Uses a known web browser user agent for HTTP communication
Yara signature match
