This test loads an unpacked extension in Google Chrome with the `--load-extension` parameter. This technique was previously used by the Grandoreiro malware to load a malicious extension that would capture the browsing history, steal cookies and other user information. Other malwares also leverage this technique to hijack searches, steal passwords, inject ads, and more.
