One afternoon, a website completely defeated me.
I was on my MacBook, trying to do the most boring thing imaginable: log into a Korean bank. The site told me to install a security program first. Fine. I installed it. I refreshed the page. It said the program was not installed. So I installed it again. Refresh. Still not installed. Install. Refresh. Not installed.
I sat there watching the same message reload, doing the same thing over and over, getting the same result — which, depending on who you ask, is either the definition of insanity or just the definition of using a Korean website on a Mac.
And I’m Korean. I grew up here. If I can’t get past the login screen, imagine being a foreigner who just moved to Seoul, opened a bank account, and sat down to pay a bill online for the first time.
Welcome to the strange, stubborn world of Korean banking security software — and the reason it still exists in 2026 is far more interesting than “Korea is behind.”
The Korea you’re picturing is already dead
If you’ve read anything about Korean technology, you probably know the joke: “Korea has the fastest internet on Earth, but it still runs on Internet Explorer and ActiveX.” For years that was painfully true. To do online banking, you had to use IE, on Windows, and install a pile of plugins that worked nowhere else.
Here’s the thing nobody updated you on: that era is genuinely over.
Microsoft killed Internet Explorer for good on June 15, 2022. (As I write this, that’s almost exactly four years ago — it’s dead, buried, and not coming back.) ActiveX has been ripped out of the vast majority of Korean websites; by 2020, around 91% of the country’s top 500 private sites had already removed it. Even the infamous gongin-injeungseo (공인인증서, the old mandatory “official” certificate) lost its legal monopoly. These days most people verify their identity through simple app-based logins like KakaoTalk, Naver, PASS, or Toss — one fingerprint, no plugins, no installs.
So if your mental image of Korea is a nation hunched over Internet Explorer 8, you can let that go. We use Chrome and Edge like everyone else. That meme belongs in a museum.
Which makes what comes next even stranger.
But the real weirdness never left
Korea didn’t actually solve the problem. It just deleted Internet Explorer. The habit underneath IE — making you install software onto your computer just to open a website — survived completely intact.
Open a typical Korean bank website today and, before it even lets you type your password, it will ask you to install around five separate security applications. A keyboard-encryption tool. An antivirus-style agent. A firewall thing. A program whose job is apparently to manage the other programs. They no longer ride in on ActiveX — now they’re standalone downloads — but from where you’re sitting, refreshing the page for the fifth time, the difference is academic.
And this isn’t just my bad afternoon. A KAIST study published in January 2026 surveyed 400 Koreans and found that 97.4% had these security programs installed — and nearly 60% of them had no idea what the programs actually do. When the researchers examined 48 real computers, the average machine was running nine of these programs, many of them years out of date.
Here’s the punchline the researchers landed on: because this software is essentially mandatory and sits on millions of machines, it has become an attractive target rather than a shield. The thing installed to keep you safe is now one of the most appealing things to attack. You install nine programs to protect one Korean bank login, and end up with nine new doors instead of one stronger lock.
So why don’t Korean banks just delete the security software?
This is the question every foreigner eventually asks, usually while staring at install prompt number three. And the honest answer is: it’s not laziness, it’s incentives.
Think about who carries the risk. If money disappears from your account, the bank wants to be able to say, “We required you to install our security software.” That sentence is a shield — for them. The moment they remove the software, that defense disappears and the blame slides back toward the bank. So nobody wants to be the person who pulls it out.
There’s also a cost angle. Pushing a bundle of programs onto your computer is cheaper than rebuilding authentication properly on the server side. And there’s plain inertia: when something is already installed on millions of machines and “works,” ripping it out is a project nobody volunteers to lead. So it stays. Year after year, refresh after refresh.
It’s the kind of system that survives not because anyone defends it, but because nobody is rewarded for killing it.
Meanwhile, your phone lives in the future
Now here’s the twist that makes Korea genuinely confusing instead of just frustrating: open the exact same Korean bank on your phone, and it’s one of the best banking experiences on the planet.
One fingerprint. Or one glance at the camera. Money sent in about three seconds. No installs. No loops. No MacBook meltdown. Apps like Toss made sending money so frictionless that I sometimes forget other countries still ask for routing numbers and three business days. KakaoTalk handles your chats, your payments, your identity verification, and somehow your dinner delivery, all without a single “please install” screen.
So Koreans did the only rational thing: we abandoned the PC. Desktop banking has quietly become the option of last resort, the thing you only touch when some form absolutely refuses to work on mobile. The phone is where real life happens. The computer is where you go to suffer.
The same country, the same bank, the same person — a glorious experience on a 6-inch screen, and a 2005 horror movie on a 27-inch one.
So, is Korea behind?
No. That’s the wrong word, and it’s the conclusion every outdated article jumps to.
Korea has world-class internet speeds and arguably the smoothest mobile experience anywhere. It’s not behind — it’s split. One narrow corner, desktop security, got frozen in time around 1999 and everyone learned to route around it instead of fixing it. The rest sprinted ahead. (And yes, before you ask — some government offices and hospitals do still run on fax machines. The freeze didn’t only hit banking.)
So if you’re moving to Korea, here’s my honest, lived advice: do almost everything on your phone. That’s the real Korea, and it’s wonderful. But if the day comes when you absolutely must use a Korean bank or government site on a computer — well, good luck. And if you’re on a Mac, my genuine suggestion is to befriend exactly one person who owns a Windows PC. You’ll need them. I promise.
