I'm guessing an "internal tools scaffold" is something like Goose: https://github.com/block/goose

Instead of just generating a patch (copilot style), it generates the patch, applies the patch, runs the code, and then iterates based on the execution output.

Square | AppSec, vulnerability discovery, pen testing | Remote in North America

We're hiring people to find vulnerabilities in Square products and services! The team is brand-new with lots of opportunity to choose the type of AppSec work you want to focus on. Fully remote is an option. There are more details here: https://smrtr.io/6T58-

We're also hiring for lots of other security roles. Please feel free to email me: dhintz@squareup.com

isTrusted can apparently be spoofed

isTrusted cannot be spoofed in this situation, which is its intended use in Chrome. A Chrome extension in the isolated world is receiving events from the main world and checking isTrusted for those events.

Yes, we're pushing the notification to a new tab (which can't be blocked or interfered with)

We went through a similar iteration with Password Alert. If you're setting focus on the new tab, an onBlur event could indicate that the current page has lost focus, perhaps due to the warning tab. I think notifying the user is still net-positive for the user's security.

LastPass also detects you enter your master password on an incorrect domain and notifies you immediately of your mistake

Interesting! How does it do this?

I agree that it's not yet ready for general use, but what hardening do you expect to happen in the coming months?

I'm one of the original end-to-end authors, but haven't worked on it recently.

A while ago this was sort of leaked on HN, but someone called it "really unlikely": https://news.ycombinator.com/item?id=8566485 https://news.ycombinator.com/item?id=8566022

Now we've publicly released my project. It's a bit different than most phishing detection -- it detects phishing by noticing where the user has typed their password. Please try it and let me know what you think. The source code is here: https://github.com/google/password-alert It's available in the Chrome Web Store here: https://chrome.google.com/webstore/detail/password-alert/noo...

A good friend saw the SXSW screening of the first two episodes and loved it. He's founded a failed company, founded a successful small company, coded for a failed company, and is currently in SF coding for a startup.

A lot of the jokes are tech-hilarious and well-informed about the tech culture here. Mike Judge's long-time residence, Austin, has plenty of tech and some startups, but of course not as much as the Bay Area.

It's a comedy so I expect it to poke fun at our culture.

If your browser gets JavaScript crypto from webmail.example.com every time you visit webmail.example.com then there's nothing stopping webmail.example.com from serving malicious JavaScript crypto that steals your keys or unencrypted data. Even though the JavaScript runs locally, the code is supplied by webmail.example.com. There's a discussion of this and a few other issues here: http://www.matasano.com/articles/javascript-cryptography/

JavaScript in web browsers also has a few other issues, such as side-channel timing attacks and the lack of control of memory.

Hi Rudhir, Drew from the Google Security team here. Actually, the authentication cookies that are set on mail.google.com aren't sent when you visit google.com, so the scenario you described wouldn't work. Those secure cookies are only sent over SSL. That's good news for the people in your scenario!
