Signatures
Antivirus / Scanner detection for submitted sample
Antivirus detection for dropped file
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for dropped file
Multi AV Scanner detection for submitted file
System process connects to network (likely due to code injection or exploit)
Changes security center settings (notifications, updates, antivirus, firewall)
Drops executables to the windows directory (C:\Windows) and starts them
Machine Learning detection for dropped file
Machine Learning detection for sample
Antivirus or Machine Learning detection for unpacked file
Checks if Antivirus/Antispyware/Firewall program is installed (via WMI)
Connects to several IPs in different countries
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Creates files inside the system directory
Deletes files inside the Windows folder
Drops PE files
Drops PE files to the windows directory (C:\Windows)
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
Internet Provider seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
PE file contains executable resources (Code or Archives)
Queries disk information (often used to detect virtual machines)
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sample file is different than original file name gathered from version info
Tries to load missing DLLs
Yara signature match
