Exfiltrating system information Clicking the shortcut file executes Windows built-in WMIC tool that downloads and executes a JavaScript code, which further abuses the Bitsadmin tool to download all other malicious payloads that actually perform the malicious tasks of pilfering and uploading the victim's data while disguising itself as a system process. 48% of all malicious PowerShell commands were started through WMI By: Symantec Security Response Team “Living-off-the-land” tactics—where attackers take advantage of native tools and services already present on targeted systems—have been used by both targeted attack groups and common cyber criminal gangs for some time now. This article will help those who play with CTF challenges because today we will discuss “Windows One-Liner” to use malicious commands such as PowerShell or rundll32 to get the reverse shell of the Windows system.

Last week, FireEye revealed that attackers have found new means to abuse Windows Management Instrumentation (WMI) The attack chain usually starts with a malicious link in a spear-phishing email. The link takes the victim to an LNK file designed to execute the Windows Management Instrumentation Command-line (WMIC) tool to download and execute JavaScript code. The JavaScript abuses the Bitsadmin tool to fetch payloads that are decoded using Certutil.
