File execution after IWR download with IEX
To execute a downloaded file using Invoke-Expression
(IEX) in PowerShell after downloading it with Invoke-WebRequest
(IWR), you can follow these steps:
Download the File:
UseInvoke-WebRequest
to download the file from the specified URL and save it to a local location. For example:powershell$url = "https://example.com/file.exe"
$outputPath = "C:\path\to\file.exe"
Invoke-WebRequest -Uri $url -OutFile $outputPath
Execute the Downloaded File:
After the file is downloaded, you can useInvoke-Expression
to execute it. Note that executing downloaded files can be risky, so exercise caution and ensure that you trust the source.powershellInvoke-Expression -Command $outputPath
Please note that executing downloaded files can be a security risk, as it can execute potentially harmful or malicious code on your system. Make sure you download files from trusted sources and exercise caution when executing them.
Additionally, be aware that certain security settings, such as PowerShell's execution policy, may prevent the execution of downloaded scripts or files. Adjusting the execution policy or signing the script may be required to execute the downloaded file successfully.
