I completed a PowerShell script challenge on LetsDefend !
Here are some key takeaways from this insightful experience:
? Analyzed a malicious PowerShell script and learned about code obfuscation techniques.
? Used the CyberChef tool to decode a Base64-encoded script.
? Discovered how PowerShell can run in hidden mode with the -W Hidden parameter to avoid detection.
? Learned about the -NonI parameter to prevent user interaction.
? Identified how the script communicates with external websites and disguises itself by spoofing the User-Agent string.
? Observed the use of proxy credentials to authenticate and bypass network restrictions.
? Identified the malicious URL the script connects to.
