MFA is on the checklist of every audit I have ever seen, and the tick is where most thinking stops. It should not be. The NCSC's guidance is blunt about it: not all types of MFA are created equal. Text messages can be intercepted. A bare push notification can be spammed until someone taps approve at 11pm to make it stop. That is MFA fatigue, and it works because the approval asks nothing of the user except irritation. The better versions make phishing structurally harder: number matching, so the person must see the login screen to approve it, and passkeys or hardware keys, where there is no code to type into a fake page at all. If your MFA rollout ended at "any second factor counts", the project is not finished. The factor you chose is the control. https://www.ncsc.gov.uk/guidance/multi-factor-authentication-online-services #CyberSecurity #InfoSec #MFA

Karl, I've been evangelizing Ente Auth for a little more than two years now. It remains the ONLY fully cross-platform syncing FOSS solution available.

Mobile versions were available more than a year prior, but that didn't satisfy basic cross platform requirements. Back then there was Twilio (Authy), a proprietary solution that announced the sunset of their desktop version soon after the release of Authy desktop, and you could actually migrate your database by exporting it, interestingly enough.

Not surprisingly, they soon pushed and "update" to the desktop version which cripplewared it -presumably in anticipation of Ente Auth mass migrations.

There was a report of a flakey sync between KeepassDX and KeepassSX some time ago, yet I've never experienced issues.

Having said that, you should know that NextCloud itself reports issues with .kdbx syncing if you are stupid enough to install from the Google playstore, other sources like the git repo or F-Droid are not intentionally crippled in this way, by design, and virtue of their contract with Google.

I usually don't mention using password managers together with #MFA authenticators out of an abundance of concern for being flamed by fellow security professionals, but felt it prudent to mention here; the fact is that people will do so anyway because it's convenient.

I do separate, as a best practice, the use of my passwords and my only authenticator, Ente Auth, yet keep backup copies of my #TOTP MFA keys in a .kdbx file (in the comments - not active). I believe that's advisable to keep them in a separate vault and avoids the issue of not being able to migrate (i.e., Twillio's Authy lockdown cripple).

Sure, one could break and reinitialize their MFA on each of their myriad accounts but that's indeed a Major Pain (that's a TV pun).

So for me, I'm a staunch supporter of Pass/OpenKeyChain (sync via Git) & #Ente_Auth on all of my platforms: Android, FreeBSD, Linux (I no longer use Windows) - Sync via my self-hosted Ente Auth server; and a .kdbx client appropriate for my OS, syncing that via #NextCloud. You can use #Peergoss if you prefer.

For everyone else, I usually recommend they go with a combination of Ente Auth and [VaultWarden}(https://vaultwarden.com)

That keeps everything absolutely self-hosted and 💯% #FOSS.

If you're not a stickler for self-hosting those very same solutions are still available to you, except that for #VaultWarden you need to go [HERE](https ://VaultWarden.org).

I don't do Apple, but I am aware of .kdbx clients for that particular manufacturers products and the iPhone was, I believe, the first platform that Ente Auth was released for.

Beyond that I just urge everyone to stick with 100% FOSS solutions whenever feasible (i.e., Use VaultWarden instead of BitWarden) and make sure to contribute whatever they feel is fair to the developer teams that make all of this possible.

I hope that helps!

@14mission@sfba.social @morgan@sfba.social Microsoft (and Entra ID) is retiring SMS soon, so this won't be an option for a large number of orgs and folks in the near future. SMS is also not secure and does not meet the higher security standards that many organizations are now attempting to meet. #MFA #SMS #EntraID #Microsoft

@14mission@sfba.social @morgan@sfba.social for reference: "From February 1, 2027, Microsoft-provided telecom delivery for SMS and voice will be retired for all users except Global Administrators and external users.

One server. Ten simultaneous phishing campaigns. Nigerian-origin actor confirmed. Matrix flagged zoom4usinvite[.]space as an open-directory staging server. The server backup left world-readable the day before the crawl revealed the full picture: alongside Zoom and Adobe/ClickFix droppers, the actor runs real-time Adversary-in-the-Middle kits for Google (2SV bypass), Microsoft (Authenticator + SMS bypass), and Xfinity/Comcast (password + card + SSN). Five of eleven Telegram bot tokens confirmed live at analysis time. Fingerprint: the PHP anti-bot engine explicitly whitelists MTN, Glo, Airtel, and 9mobile while blocking all cloud ASNs.

🎯 Threat Intelligence

Okta's threat intelligence team analyzed a 7GB infostealer dump released on a Telegram channel, finding 555 JWTs for AI service authentication and 1,843 unexpired tokens across 5,871 infected machines in 162 countries.

🔹 Technical Details

The dump contained 44,791 unique JWTs, of which 555 were likely related to AI service authentication. Affected services include Google, Microsoft, Anthropic, Amazon, Gamma, Notion, Character.ai, Cursor, Poe.com, and Pika AI.

Okta also identified 2,937 JWE (JSON Web Encryption) data structures. Most were set by OpenAI, which uses NextAuth.js for authentication. While JWEs can only be decrypted by the key holder, they can still be replayed for account access as long as they remain unexpired.

On the day of release, 1,843 JWTs and JWEs were unexpired. 17.7% of the 44,791 JWTs contained plaintext PII including names, phone numbers, and email addresses.

🔹 Attack Chain Analysis

1. Initial Access: Infostealers (Lumma Stealer, Vidar) infect endpoints via standard delivery methods
2. Credential Harvesting: Stealers collect credentials, session tokens, and API keys from compromised machines
3. Distribution: Stolen data sold on underground forums as stealer logs
4. Session Replay: Threat actors replay valid JWTs/JWEs to access AI services without authentication, bypassing MFA

As Jeremy Kirk, director of threat intelligence at Okta, noted: "Once successfully replayed, a threat actor is effectively logged in to an LLM service without actually logging in."

🔹 Detection Considerations

Okta states that use of these stolen tokens "makes abuse more challenging but not impossible to detect." Session replay attacks may not work universally, as some services implement additional session validation. The plaintext PII in JWTs does not expire and directly links users to specific services, creating persistent risk for social engineering and phishing campaigns.

🔹 Key Observations • 555 JWTs specifically for AI service auth out of 44,791 total • OpenAI's NextAuth.js implementation generates JWEs that are replayable despite encryption • 17.7% of JWTs expose plaintext PII that never expires • The 7GB dump spanned 162 countries and 5,871 machines

my: bankcredit card ex company1credit card ex company2superannuationmobile phone vendornbn broadband vendor do not use / support #2FA via #MFA #TOTP, & i am tearing my hair out in exasperation at these damn troglodytes. I've even just wasted a coupla hours dealing with my mobile phone vendor who overnight sent out an email that delighted me as it recommended customers setting up our online accounts with them using [direct quote from the fucken email]... MFA is a security method that requires you to prove your identity in two or more different ways, like an additional verification step as part of your login. This might include facial recognition, a dedicated authenticator app, or a unique code sent to your preferred contact method. ...only to eventually find that part of the email is bullshit. jfc, most of these are major companies, some indeed are multi-nationals, yet they still treat security as a joke. utter fuckheads! aaaaaaand yet seemingly not a week goes by without companies getting hacked & thus fucking over their customers 😡🖕

Zero to owned: Credential stealer to corporate breach The breach doesn't start with your infrastructure. It starts on a device you don't control. One dataset of 15 million infostealer logs held 687 million cookies, 43.87 million of them still active session tokens that hand over an account without ever tripping MFA. Your second factor doesn't matter if the attacker inherits the session. https://darkwiser.com/blog/zero-to-owned-mapping-the-lifecycle-of-a-credential-stealer-to-corporate-breach #Infostealer #SessionHijacking #MFA #CredentialTheft #dark_web

Friends, I need some help and advice. Microsoft recently announced retirement of Microsoft-provided SMS and voice authentication in Entra ID. Of course, "good", you say -- me, too. But I'm working with an organization that has some extremely non-techie employees, and I've got to figure out the easiest path to help them get properly on-boarded with Passkeys. Microsoft Authenticator seems to support Passkeys natively (the key is stored IN MS Authenticator). Is this the best way to do this? My non-techie users are primarily mobile phone users on Exchange Plan 1 (no "fat" client).

Interesting when a company offers an option to enter an MFA/2FA access code on the login page, while it's not possible to set up an MFA token in their account system. (They're perhaps still working on that.) #MFA
