| User nashashmi [1]: So this kid uses his home computer at his home, and they trace him down with
the IP address, and the IP address also makes a request for Windows Updates.
And that narrows down the Device ID. The device id is now traced to this kid.
That seems more likely, I hope, than Edge/Windows secretly telemetering your GDID and every URL you visit to Redmond. It's a huge privacy hole still, but they can plausibly deny they set out to track you across the web using their OS.[1] https://news.ycombinator.com/item?id=48815196#48818368 |

| > The ID is generated when Windows is set up with a Microsoft Account So not only was this “hacker” using Windows and Edge, they singed in to windows with a Microsoft account. And then used that same computer for their social media. Nice. |
| |
| ▲ | crtasm 3 hours ago | parent | next [-] | | The ID is generated even if you only create a local user account. I don't know to what extent that affects tracking/telemetry though. | |
| ▲ | steve1977 2 hours ago | parent | prev [-] | | It's fascinating, right? I'm not a "hacker" by any means, but I would probably use a Qubes based system with a dedicated "hacking" VM, only use anonymous VPNs connected from public WiFi access points (having left my mobile at home) while wearing a fake beard and STILL be paranoid that I somehow somewhere make a mistake. | | |
| ▲ | ffaccount2 2 hours ago | parent | next [-] | | That's what hackers do in popular stories, right? In reality, most cybercriminsls just don't care that much (they usually use Tor browser, though). I mean they mostly use discord and telegram (both unencrypted). Serious "hackers" are usually state sponsored now, or members of mature groups. | | |
| ▲ | Cider9986 2 hours ago | parent [-] | | They don't care, I would say they don't know. I saw an article where they analyzed the leaked IP addresses from a breach forum, and some of the top ten were Surfshark and iCloud Private relay. | | |
| ▲ | gruez an hour ago | parent [-] | | >and some of the top ten were Surfshark and iCloud Private relay. what's wrong with icloud private relay? It uses a 2-hop architecture so it's probably more private than any single-hop VPN. |
|
| |
| ▲ | Cider9986 2 hours ago | parent | prev [-] | | Qubes is probably the best option but, the last time I checked, it didn't have certain deniability features that someone with the feds in their threat model might prefer. Personally I'd say use Qubes because it might be better at preventing you from getting raided in the first place. Decisions decisions. |

| >The Global Device Identifier (GDID) is a permanent ID assigned when Windows provisions against a Microsoft Account. So again, the "make an account" is the part you ALWAYS skip. Local accounts or it technically isn't even a PC anymore. |
| |
| ▲ | ranger_danger 2 hours ago | parent [-] | | The article is misleading... the GDID is created even if you don't use a Microsoft account. |

| How exactly does Microsoft link their gdid to a hotel booking? Hotels last I saw don't collect an obscure gdid... Did this victim use edge and sync their browser history or something perhaps? |
| |
| ▲ | ndiddy 2 hours ago | parent | next [-] | | Edge has a feature where it will periodically pull the bookmarks and browsing history from any other browsers you have installed, so they'll then get sent to Microsoft and associated with your Microsoft account. This was initially enabled by default without the user's consent, although I believe now you may have to opt into it if you do a fresh Windows install. I only realized this was a thing because one time my work PC rebooted to install an update, then Edge came up instead of Firefox, but with all my Firefox tabs. I guess this was part of some effort to try to trick old people who wouldn't notice the difference into switching to Edge. Here's a news article about someone else running into this when it started happening: https://www.theverge.com/24054329/microsoft-edge-automatic-c... | | |
| ▲ | VerifiedReports 2 hours ago | parent | next [-] | | "Old" people? How about the vast majority of the public, which is not represented on HN? Not to mention that one of the many major UI regressions in Windows is the removal of title bars from application windows, which is fundamental to this "trick." Try opening a PDF in Edge and also in Acrobat. Neither window has a title bar, and they are otherwise almost identical. You have to scrutinize the very few controls around the window to determine which app you're looking at. Microsoft and its software are trash now. | | |
| ▲ | VCFundedGenYer 2 hours ago | parent | next [-] | | Edge has less browser market share than Firefox right now, it's not the "vast majority." | | |
| ▲ | simulator5g an hour ago | parent [-] | | I don’t believe that, there’s probably some missing data. Outside the techno echo chamber that HNers live in, most people use the defaults. I see people using adware browsers that were installed without their knowledge. Computers are just too complex for most people to notice details like what web browser they use. |

| ▲ | smileybarry 8 minutes ago | parent | prev [-] | | > so they'll then get sent to Microsoft and associated with your Microsoft account. The import is entirely local, the "sent to Microsoft" bit is if you have Edge sync enabled. This is identical to Chrome importing your Firefox data and then syncing it back to Google. Except the Edge import was, by reports at the time, accidentally auto-enabled. But you'd still have to sign into Edge and enable sync. |

| ▲ | CommieBobDole 3 hours ago | parent | prev | next [-] | | There's a blurb in the article: >"Massgrave, the group behind Microsoft Activation Scripts, has noted that Windows setup sends hardware info to Microsoft and receives identifiers back that are later used for Store access and licensing. Blocking GDID assignment breaks both activation and UWP apps." I think probably it sends the gdid back to Microsoft as part of telemetry/updates/MS account periodic re-auth, which lets them know the current IP address, and then once the government has Microsoft's logs and the various target websites' logs, they can correlate based on IP address. I don't think it's actually sending the gdid to the web sites. Maybe. This serves to further illustrate that nobody should be using Windows for anything that involves the need for privacy. And doubly, triply, and morefold so, nobody should ever sign a Windows machine into a MS account for any reason. | |
| ▲ | crtasm 3 hours ago | parent | prev | next [-] | | Edge seems likely. Its settings include: >Send optional diagnostic data to improve Microsoft products [Includes how you use the browser, websites you visit, and enhanced error reporting. Determined by your Windows diagnostic data setting] >Allow Microsoft to save your browsing activity including history, usage, favourites, web content, and other browsing data to personalise and improve Microsoft Edge and Microsoft services like ads, search, shopping, news, and Copilot [Includes your history, usage, favourites, web content and other browsing data] | |

| How does the GDID compare to the UDID (Unique Device Identifier) and serial number in iOS; and the Apple Hardware UUID and serial number of Macs? |
| |
| ▲ | PunchyHamster 2 hours ago | parent [-] | | well, mostly the name. And the fact MS gave away GDID - IP mapping to the govt. | | |
| ▲ | autoexec an hour ago | parent [-] | | Is there any reason to think that the government couldn't force Apple to hand over the same data? They may or may not have taken over entire rooms at Apple (https://en.wikipedia.org/wiki/Room_641A) but you can bet they've at least got devices sitting on their network collecting data. |

| They caught a 19 year old hacker that uses Edge, and all it took was the privacy of 1.4 billion Windows users. |

| One more proof that Windows is malware. |
| |
| ▲ | ranger_danger 2 hours ago | parent [-] | | Linux has the same kind of identifier at /etc/machine-id... readable by default by basically any application on the system. | | |
| ▲ | drnick1 33 minutes ago | parent | next [-] | | This is a systemd identifier, not strictly speaking a "Linux" identifier. In any case, an executable allowed to run on a host can trivially fingerprint the machine it is running on using a combination of hardware identifiers. Removing or rotating machine-id does not buy you any privacy against a malicious app. What I find most surprising in this story is how careless these "hackers" were. You would think that people engaged in this type of activities would use throwaway devices running free operating systems and VMs, not personal devices logged into Snapchat and Facebook. | |
| ▲ | aftbit 2 hours ago | parent | prev | next [-] | | Which is also well documented and trivially rotatable by anyone with root on the machine. How do you rotate the MS identifier? | | | |
