None of Google's 85,000 Employees Have Been Phished in More Than a Year After Company Required Them to Use Physical Security Keys For 2FA (krebsonsecurity.com)

Google has not had any of its 85,000+ employees successfully phished on their work-related accounts since early 2017, when it began requiring all employees to use physical Security Keys in place of passwords and one-time codes, the company told KrebsOnSecurity. From the report: Security Keys are inexpensive USB-based devices that offer an alternative approach to two-factor authentication (2FA), which requires the user to log in to a Web site using something they know (the password) and something they have (e.g., a mobile device). A Google spokesperson said Security Keys now form the basis of all account access at Google. "We have had no reported or confirmed account takeovers since implementing security keys at Google," the spokesperson said. "Users might be asked to authenticate using their security key for many different apps/reasons. It all depends on the sensitivity of the app and the risk of the user at that point in time." The basic idea behind two-factor authentication is that even if thieves manage to phish or steal your password, they still cannot log in to your account unless they also hack or possess that second factor.

Wow a whole year

I've never fallen for a phishing email with or without 2fa.

If Google's getting kudos after a year, I want a goddamned payout.

Re:Wow a whole year

[Actually, I do RTFA]

Google has 85,000 employees. For a phishing attack to work, it has to work on the dumbest employee.

Since this implies that there were successful phishing attacks more than a year ago, congratulations on being better at security than the person in Google who gives the least shits.

2FA finally

[supernova87a]

It was this article that finally made me switch from SMS verification codes for my personal email (gmail): Wired article

And I went to Google Authenticator only after I figured out how to put the same code on multiple devices and assure myself that I had enough backup hard copies of keys that I would not likely get locked out permanently should I ever lose my phone, etc.

The U2F works great for corporate, etc. where you have a support team who can help you in case you lose it or forget anything. They can make you come in person and prove that you are you.

The problem with implementing this (without enough backups) for personal is that if you ever lose all of your key info or code generator, you are absolutely fucked because there is no way to prove who you are to Google and have them reset your password / security. So you've got to have multiple backups in different places should your house ever burn down, etc.

JWZ had a writeup about SMS, Google Auth and OTP

Using a TOTP solution like 1password or Google Authenticator is better than SMS, because unlike SMS it's very difficult to hijack. But it's still not as good as security keys (AKA FIDO U2F) as described in this article, because it can be phished. If you're certain that you could never, under any circumstances, be social-engineered into giving up your TOTP code then you're probably wrong about how gullible you are, because there are some really talented social engineers out there. But with U2F, you just can't do it.

Also, U2F is much more convenient. You have to buy a USB dongle (or three) and stick one in your USB port, but then when you have to authenticate all you have to do is touch it. So much more convenient than looking at a number and typing it in. I work for Google, and the various systems I use require me to authenticate about a dozen times every day -- but often the authentication required is U2F only (because I already authenticated recently with my password) so it's very low-effort. The same would not be true if TOTP were required.

Do keep in mind if you go U2F only, though, that losing or destroying your security key means you're locked out of your account and the only available recovery process will be intentionally tortuous and may fail. So use multiple security keys, and I'd suggest keeping a set of backup codes in a safe place that is also quite inconvenient for you to access (making it hard for anyone to social engineer you into giving them a code).

But how many thousands of hours were lost?

[greenwow]

We started requiring a YubiKey USB key, and hours worked by people from home dropped over 20%! YubiKey claims to be FIPS compliant which is what our SSAE 16 requirements require. Security is important, but blocking people working extra hours is a huge cost.
