A bank’s privacy policy lists a lot of data they collect, including customers’ MAC addresses. I was dumbfounded. How is that possible? The router on your LAN obviously knows your device’s MAC address. And I guess the ISP’s router would know your gateway’s MAC address. But from there wouldn’t the bank only see your IP address from the WAN?

Then it occurred to me-- the bank has a smartphone app. So the app likely demands perms to get the phone’s MAC. But then what would the likely purpose be? To check vendor consistencies (to block VMs) and raise impostor flags if your MAC changes?

(update) Another question: instead of using the bank’s shitty phone app, you use their shitty web app instead. I would assume the JavaScript engine is naturally blocked from obtaining your MAC address and transmitting it. But I would like a sanity check.. anyone know for certain?

So the question is, does Russia really have a hard time getting spies in? Or is it more of a matter of saving money on the travel effort and letting a couple local kids be the fall guys? Because the recruitment itself has some risk. Netherlands probably needs some counter spies posing as kids looking to be recruited.

I’ve been using JSignPDF for this by running:

java -jar jsignpdf-1.6.1/JSignPdf.jar

The tool you link looks quite a bit more comprehensive and user friendly. I think w/JSignPDF it just does the task of signing. You still need to generate SSL certs. I’ve not tried docuseal but looks like it tries to be foolproof.
