Friendly reminder to change your master password. You’re one SIM jack away from having your life locked away for ransom. They didn’t breach the seeds, but next time who knows. I would start migrating and changing 2FA codes just in case. You never know who might be spraying.

The problem is so many services requiring SMS to be that second factor. From what I’ve heard it’s easy enough to steal a sim that if you’re being explicitly targeted it’s basically the same as no second factor. Yet even if using an authenticator app most services require you to still have SMS/phone as another option for the 2FA.

For Authy specifically they’d need to guess your master password and then hijack your phone number, and for users of Authy I suspect their passwords are not easily guessed as it’s already a step above the standard SMS only 2FA most services require.

I realized long time ago that I don’t want my 2FA be tied to my phone number. And then i found you can’t export your data from Authy because they know they are scummy fucks and don’t want to anyone to leave

You can, though. But not through their app. Someone reverse engineered their protocol and wrote a program that connects like a new client, which you then approve, and it dumps all your random seeds into a text file. I then put them all into Keepass.

Edit: Unfortunately, the author has deprecated the project as Authy has added some attestations to their API, seemingly for this exact issue. https://github.com/alexzorin/authy?tab=readme-ov-file

People keep acting like Authy is betraying them by not having an export feature, but why exactly are you leaving Authy to begin with? Because they are a security risk?

You’re gonna leave Authy a copy of your seeds? That defeats the purpose.

Re-key your MFA codes on the way out. Security isn’t necessarily convenient.

They got rid of the desktop app.

Also, with shouldn’t have your seeds. They’re encrypted before they are transmitted to their servers and only decrypted on the device.

Exporting data from a 2FA app sounds like the opposite of secure. Not to mention you don’t want your 2FA codes on Authy (or any other 2FA app) to remain valid if you’re not using it.

When I switched from Google Authenticator to Authy years ago, I went through each 2FA-enabled account one by one to disable 2FA and then re-enable it using Authy. It’s a long process depending on how many accounts you have 2FA enabled on, but it’s worth it.

Reading the OP, looks like it’s time to generate new keys for all my 2FA accounts.

If you can’t export / save / transfer codes then you need to regenerate all your 2fa codes every time you switch to a new device.

2FA doesn’t need to be infallible, it just needs to be a second factor.

I used this method to export my twitch 2FA to Aegis. although I did this a few years ago, I think it still works

Edit: reading though comments made me realise Authy’s desktop app doesnt seem to be a thing anymore, so sadly I dont think it works anymore

On Android, I replaced Authy with the open-source Aegis app. It’s just as functional, allows exporting, and doesn’t tie your data to your phone number (nor store it on a central system–not sure if Authy does this or not).

Use TOTP wherever possible. It’s standardized, and typically can be found somewhere if you keep digging hard enough.

Plenty of services push their own proprietary systems hard though. Looking at you M$

I also find this infuriating. I had a service offer TOTP for authentication. Installed an open source TOTP Aap, scanned the QR and voila.

The service meanwhile can control whether they want to generate a new token or give out the old one again, for instance when a device was lost.

It is the most easy, most convenient solution both for the service provider and the client. There is no excuse for any other 2FA system to be used.

Of course. It was on the office phone that gets passed around to whichever tech is on call. The on-call tech left it at Mcdonalds accidentally.

‘hacked’. Eh. There was an API endpoint left open that allowed them to basically just spam it with no rate limiting. They used the lack of a rate limit to just pull the data out of the API that it was made to produce.

Yeah. They got data in a way that was not intended. That’s a hack. It’s not always about subverting something by clickity-clacking like in the movies.

Exploit. The system worked as intended, just without a rate limit. A hack would be relying on a vulnerability in the software to make it not function as programmed.

It’s the difference between finding a angle in a game world that causes your character to climb steeper than it should, vs rewriting memory locations to no-clip through everything. One causes the system to act in a way that it otherwise wouldn’t (SQL injections, etc) – the other, is using the system exactly as it was programmed.

Downloading videos from YouTube isn’t “Hacking” YouTube. Even though it’s using the API in a way it wasn’t intended. Right-clicking a webpage and viewing the source code isn’t hacking - even if the website you’re looking at doesn’t want you looking at the source.

A missing rate limit is a vulnerability, or a weakness, depending on the definition. You’re playing smart without having an idea of what you’re talking about. Here you go:

https://cwe.mitre.org/data/definitions/799.html

YouTube videos are public, and as such it’s not really hacking. If you were able to download private videos, for example, it would be a vulnerability like “Improper Access Control”. It does not matter in the least whether you use an “exploit” in your definition (which is wrong) or “just increment the video ID”.

The result is a breach of confidentiality, and as such this is to be classified as a “hack”.

Hint – by manipulating or exploiting its code

Which I am explaining, they…did…not…do…

They did nothing to the code. They didn’t break the code, they didn’t cause the code to do anything it wasn’t designed to do. They did not exploit any code. They used an API endpoint that was in the open. For its intended purpose, to verify phone numbers. The api verified phone numbers, they verified phone numbers with the api. The only thing they did here…was they did verification on a lot of phone numbers.

That’s what most exploit-based hacks are. A developer makes a dumb mistake and then someone exploits it to do something they shouldn’t be able to do.
