Sigma detected: Invoke-Obfuscation CLIP+ Launcher
Sigma detected: Invoke-Obfuscation VAR+ Launcher
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
Yara detected Generic Downloader
Allocates memory with a write watch (potentially for evading sandboxes)
Checks if the current process is being debugged
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
Drops PE files
Enables debug privileges
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
Queries sensitive Operating System Information (via WMI, Win32_ComputerSystem, often done 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)

AsyncRAT | AsyncRAT is a Remote Access Tool (RAT) designed to remotely monitor and control other computers through a secure encrypted connection. It is an open source remote administration tool, however, it could also be used maliciously because it provides functionality such as keylogger, remote desktop control, and many other functions that may cause harm to the victims computer. In addition, AsyncRAT can be delivered via various methods such as spear-phishing, malvertising, exploit kit and other techniques. | No Attribution |
