Unusual verification pages are easier to assess when I focus on what the site actually asked me to do rather than how professional it looked, so I note fake captcha scam among details about redirects, clipboard instructions, permission prompts, and any command that appeared. Simply closing a tab is very different from having already executed something on the computer. I’d also record the browser, the page address, and whether any download started. The next step depends on the action taken, which is why the exact sequence is more useful than a general description that the page seemed suspicious.
