He said "This is the closest I've ever come to falling for a Gmail phishing attack. If it hadn't been for my high-DPI screen making the image fuzzy…"
How does this Gmail phishing attack work?
1. Attacker will send an email to your Gmail account with Malicious Email Attachments.
2. On clicking the attachments, a new tab opens up and you are asked to sign in Gmail again. Which looks like original Google’s login page.
You can identify the phishing page just look at the URL of a page, original web page start with https:// but mostly phishing page not adopting HTTPS (also known as HTTP over TLS, or Transport Layer Security)
In this attack URL starting with data:text/html,https://accounts.google.com instead of https://accounts.google.com
3. Once you complete sign-in, your account has been hacked.
4. The attackers log in to your account immediately once they get your account password.Once they have access to your account, the attacker also has full access to all your emails including sent and received at this point and may download the whole lot.

Technical Details :
This phishing technique uses something called a ‘data URI’ to include a complete file in the browser location bar. A data URI is a base64 encoded string that represents a file. You might see in the address bar ‘data:text/html…..’ that is actually a very long string of text (base64-encoded version).

Data URIs are composed of four parts: a prefix (data:), a MIME type indicating the type of data, an optional base64 token if non-textual, and the data itself:
data:[<mediatype>][;base64],<data>
