Signatures
Antivirus / Scanner detection for submitted sample
Antivirus detection for URL or domain
Multi AV Scanner detection for submitted file
Sigma detected: Capture Wi-Fi password
Yara detected Flesh Stealer
Connects to many ports of the same IP (likely port scanning)
Found many strings related to Crypto-Wallets (likely being stolen)
Machine Learning detection for sample
Queries memory information (via WMI often done to detect virtual machines)
Queries sensitive Plug and Play Device Information (via WMI, Win32_PnPEntity, often done to detect virtual machines)
Queries sensitive physical memory information (via WMI, Win32_PhysicalMemory, often done to detect virtual machines)
Queries sensitive video device information (via WMI, Win32_VideoController, often done to detect virtual machines)
Tries to harvest and steal WLAN passwords
Tries to harvest and steal browser information (history, passwords, etc)
Tries to steal Mail credentials (via file / registry access)
Uses netsh to modify the Windows network and firewall settings
Allocates memory with a write watch (potentially for evading sandboxes)
Binary contains a suspicious time stamp
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
Enables debug privileges
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
HTTP GET or POST without a user agent
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
JA3 SSL client fingerprint seen in connection with other malware
May check the online IP address of the machine
May sleep (evasive loops) to hinder dynamic analysis
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, often done to detect virtual machines)
Queries sensitive Operating System Information (via WMI, Win32_ComputerSystem, often done to detect virtual machines)
Queries sensitive processor information (via WMI, Win32_Processor, often done to detect virtual machines)
Queries the product ID of Windows
Queries the volume information (name, serial number etc) of a device
Sample file is different than original file name gathered from version info
Uses code obfuscation techniques (call, push, ret)
