Yes, you should be able to. In essence, the state of the TPM is represented in the values of the PCRs (Platform Configuration Registers). Those are hash-extended through the boot p…

Even with a ported number, inbound call routing still heavily relies on the "number range" owner to direct the incoming call to the correct network. If the original number range ow…

When roaming, your home network is needed for routing incoming calls to you, and handling authenticating your device to the visited network.

There are absolutely ways to intercept a call from a targeted user that would be viable to use to gain access to a mid to high value user's funds. SS7 call routing and rogue 2G bas…

You need a SIM card (ideally) with support for elliptic curve crypto, and some additional fields added in the profile (SIM services 124 and 125). You can then, once those services …

In terms of existing examples, there's a few equivalent (or at least similar) fields defined as SIM files - for example, the FPLMN (forbidden PLMN) list of networks your phone shou…

A lot of the patents needed to implement mobile standards are designated as "standards essential patents", meaning that the party bringing them up the table in the standards commit…

You might find Privacy Pass of interest then - https://help.kagi.com/kagi/privacy/privacy-pass.html It should be out in the next day or so.

There's a couple of options in settings worth checking, as Netguard works for me when roaming just fine. Under Settings > Defaults, make sure you don't have "block roaming" turned …

I recently came across a signature check that was (correctly) checking the signature against a public key... The issue was the public key itself was unauthenticated, and provided b…

Thanks - yeah it seems like this is supported in FIDO 2.1 (but not 2.0). I suspect this is only implemented in Yubikey 5.7 and above. Once the technology is there to support it, ho…

That's a pretty neat solution. I like that idea. If you wanted to go a step further, you could use a smartcard with hardware PIN reader as a PKCS11 crypto device, and use that to d…

That's a fair point, although as the PIN is validated locally, you could argue from the server perspective you gain a second (knowledge) factor, but from a local perspective it's e…

I share your paranoia and felt that passkeys were a step back as anything getting access to your browser extension memory can realistically dump both your "password" and MFA ("pass…

Yeah, a fair point (though if you can't manage keys one by one that seems a massive usability issue and oversight with no safe path to resolution). This adds another step needing c…

The downside of this (at least in my personal view) is it's a regression from the elevated security you got with non-resident FIDO/U2F MFA. The moment you go "passkey" and have to …

TOTP codes are phishable and repayable in real-time - both via web (visiting the wrong site which asks for a TOTP and relays it within a few seconds), and via social engineering ov…

Which? is a UK brand, and in the UK it's fairly common to see the postcode (or rather the first couple of digits) used to determine which regional programming a user wants, given t…

Readeck saves an archived copy of the links you save (where it can). From their docs, "Every bookmark is stored in a single, immutable, ZIP file. Parts of this file (HTML content, …

The issue so far seems to be that most OSs don't really have an effective way to restrict that file to a single application. User-oriented filesystem permissions don't work, as all…

When browsing a site full of JS-heavy ads, sure. When running a browser performance benchmark, generally not - the ad block extension adds an overhead to the page. I saw this when …

One other potential area of variability could come from browser extensions - I imagine that users who compare browser power performance are more technical than the median user, and…

It certainly does - if you remain current then not a lot has really changed. If you understand the principles of control systems and how an electrical grid works, this is broadly "…

A good point - perhaps the focus is too heavy on paperwork or "measurable compliance". From experience in this sector though, I think the real issue is a lack of technical awarenes…
