It's basically required in South Korea for online shopping. The link to the IE 0 day is written in Korean.

No longer required by the government as of recently: https://www.theregister.com/2020/12/10/south_korea_activex_c...

Unsure on whether major sites have gotten around to removing it though, perhaps a Korean HN reader could comment.

I remember IE was required for the South Korean government issued digital certificate (required for all internet-based retail transactions and likely others).

I guess I had assumed that the standard was compatible with newer versions of Windows or MS browsers. Really sad if it isn’t.

For some things in SK you have to download a bunch of weird proprietary government .exe's that seem to only run in conjunction with specific combinations of windows and IE. I was pretty shocked when my wife and I went to get our marriage certificate from the government, and going to get our marriage certificate was finding an old windows NT system at her college library that everyone used to do their government related .exe stuff. We had to download 2 or 3 apps to do it, I'm not even sure what they all did, just a bunch of programs you had to run in a specific order, some of them provided iFrame type windows to logins, it was really strange.

I wonder why they needed an active x control for that. TLS/SSL client certificates have been supported by all browsers since basically forever, going back even further than active x.

If I had to guess, HTTPS / SSL was governed by US export restrictions above a certain strength so S Korea managed to use the existing extensibility built into the browser the government wanted to support.

It's ActiveX-based, which essentially runs nowhere but IE. Edge's support for ActiveX is running it in an IE tab.

Yes, I roughly understand the limitations of the existing implementation. but it is not the only browser or platform and it’s not like the S Korean government is not capable of noticing the market share / cybersecurity trends of the past decade+.

I was under the impression that SK was a technologically advanced country. I guess not the government then.

If Microsoft suddenly disabled all IE installations in South Korea, they'd have no choice but to change. Sometimes I wonder if the Apple-style "this just won't work at all anymore" attitude isn't that bad.

It has its places, given the correct trade-off, it works well. Not allowing flash was good because iOS was a growing market with no preexisting businesses relying on flash on iOS to work.

Sounds like a great way for Microsoft to lose a lot of market share fast.

There's no ActiveX on macOS or Linux either.

Not in SK, but in China Here basically all banks require ActiveX, and if you don't have an Windows computer(Mac), what you can do is to use their app, which of course is super sluggish.

This is probably it, thank you for clarifying - I've got a few friends in SK and they always complain about this, should have thought of that!

Do you know the latest on IE use? The article I posted is from 2017 and promises modernization.

I submitted the article here, hopefully we get an on-the-ground update. https://news.ycombinator.com/item?id=26656052

Looks like it was abolished last year: https://10mag.com/the-end-is-finally-near-for-koreas-infamou...

My understanding (not sure how accurate or up-to-date) is that Windows still opens some file formats using Internet Explorer (possibly depending on other OS/domain settings). The Windows Help File (.chm) or something similar comes to mind.

Also worth pointing out that security researchers targeting specific platforms/applications (say a specific version of older Windows where one particular organization has applications which require a specific version of IE) might be a valuable stack for the researcher to spend time on.

That said, those stacks/environments should be treated like a meth lab: you want to be very careful what you do with it and it shouldn’t be commingled with where you live and play.

Isn’t the latest IE just a thin veneer atop Chrome anyway?

Edge is Microsoft's new browser that is based on Chromium. It is distinct from Internet Explorer which is effectively deprecated but still used somewhat widely as many legacy enterprise applications still require it.

The recent versions of Edge are based on Chromium, but originally it used Spartan (which was the successor to IE’s Trident)

Internet Explorer is an older browser.

Edge is the Microsoft browser whose newer versions are based on Chromium.
