A sophisticated phishing campaign is currently leveraging a subtle typographical trick to bypass user vigilance, deceiving victims into handing over sensitive login credentials. Attackers utilize the domain “rnicrosoft.com” to impersonate the tech giant.

By replacing the letter ‘m’ with the combination of ‘r’ and ‘n’, fraudsters create a visual doppleganger that is nearly indistinguishable from the legitimate domain at a casual glance.

This technique, known as typosquatting, relies heavily on the font rendering used in modern email clients and web browsers.

Shitty keming strikes again

[–] TomMasz@piefed.social 7 points 2 days ago

Good typography saves lives.

I can't wait for the .corn TLD.

I'm kinda surprised Microsoft hasn't bought that domain long time ago... That trick is like decades old

On the one hand, it can help mitigate phishing attacks that could cost millions. On the other hand, rnicrosoft would have to spend 20 pounds in something not AI related.

Surely you can see why it's not an easy solution.

Devils advocate: it's not their responsibly to prevent third parties impersonating them. But it would be pretty damm nice if they did.

You would think it would be an easy up-sell by the domain registrars to offer sound and look a like domains when you registering and renewing your domain

[–] lauha@lemmy.world 7 points 3 days ago

That would assume they care about their users

Kerning or Keming?

But thanks for the link had a good "lol" from those (few) posts.

[–] frongt@lemmy.zip 6 points 3 days ago

Kerning when it's good, keming when it's bad.

[–] samus12345@sh.itjust.works 8 points 2 days ago

"Hackers?" Has the meaning really degraded so much that this is considered hacking?

[–] eestileib@lemmy.blahaj.zone 27 points 3 days ago (3 children)

Ye olde hornograph attack, you mean…

[–] eestileib@lemmy.blahaj.zone 8 points 3 days ago

These hœs ain't loya1.

[–] frongt@lemmy.zip 11 points 3 days ago

Technically no, since it's different characters. This is keming.

Another reason to Iike rnonospace fonts.

[–] Sunsofold@lemmings.world 5 points 2 days ago

What is old is new again.

[–] Cyber@feddit.uk 10 points 3 days ago (1 children)

Back to monospaced fonts then.

[–] trk@aussie.zone 7 points 3 days ago (1 children)

Honestly not a bad idea for things like filenames and URLs.

I'll go variable width fonts, with it without serifs, for a wall of text... But for something short and critical I want to trust what I'm seeing.

Also bring back the line through 0s so you know it's a number.

l also replaced 'I's with 'l's and vice-versa in some of my previous comments and haven't yet seen anyone react to them.

Hopefully someone finds out the ones I did today.

Well, here's 1, l spotted:

l did something simiIar in my original repIy, but it Iooked too weird, so gave up.

(0r did l?)

It feels like there's a lot wrong going on here but my sleeping pill is starting to kick in so if anyone wants me to explain my thoughts ask in the morning
