Phishing in disguise: Homograph attacks and Cyrillic scams are fooling millions

What if you got an email from your bank saying there's a problem with your account, and all you need to do to fix it is click this link: http://citibаnk.com? The email looks legit, complete with your bank's logos—but you're no rookie. You've been reading this blog for a while, so you know things aren't always as they seem. You hover over the URL, and it looks totally legit... But here's the kicker—scammers are using Cyrillic letters to disguise fake websites. Something that an untrained eye wouldn’t notice, detect, and totally fall for it.

But hold up, what's Cyrillic, and what are these scams all about? Glad you asked because, in this article, we'll break down exactly what Cyrillic scams are and how to spot them. As an added bonus, we'll show you how having Guardio by your side can protect you, even if you do end up clicking that sketchy link. Ready? Let's get this party started!

Is that a real link from your bank?

Why risk it? Let Guardio do the guess work for you, insuring that every link you click is 100% secure.

What is a homograph attack in cyber security?

Well, a homograph is like a master of disguise in the world of letters. The term “homograph” refers to characters that look so similar to each other that the average user can't tell them apart at a glance. In simple terms, it’s a character that looks exactly like another one but means something totally different. Think of it as a letter with an alter ego. For example, the Cyrillic letter “а” looks just like the Latin “a” but isn’t the same at all. Scammers love using homographs because they can trick you into thinking you're visiting a safe website, like your bank, when in reality, you're being lured into a trap.

What is a Cyrillic attack?

Ah, Cyrillic! It’s an alphabet used in many Slavic languages like Russian, Bulgarian, and Serbian. It’s got some letters that look just like our Latin alphabet but with a sneaky twist. This is where the magic—or rather, the mischief—happens. Scammers use Cyrillic letters to craft URLs that look legit but lead you straight into their lair. So, that link you clicked? It’s not taking you to Citibank; it's leading you somewhere far more dangerous.

Cyrillic scams and homograph attacks combined

When you combine these two elements, you get a recipe for cyber deception that's both cunning and dangerous. Homographs paired with Cyrillic characters create the perfect storm for phishing scams, tricking even the savviest internet users. It's like a digital shell game, where spotting the real site from the fake one becomes a challenge for the untrained eye.

These scams take phishing attacks to a whole new level exploiting the visual similarities between Cyrillic and Latin characters to create fake websites that look almost identical to legitimate ones. Hackers using visually similar characters to deceive in phishing schemes rely on this trick to lure you into clicking on malicious links. It doesn't matter what phony site the scammer creates—whether it's a fake lookalike to your bank site, Netflix, or a shopping site—the intention is always the same: to get you to click on the link. Once you do, you’re either navigated to a scam website or malicious malware gets downloaded to your device. For the scammers, the goal remains the same: to steal your cash, personal info, and maybe even your identity.

How Cyrillic homograph attacks

Cyrillic homograph attacks work in a pretty straightforward yet deviously clever way. A scammer registers a domain name using Cyrillic characters that look like Latin ones—say, replacing a Latin “a” with a Cyrillic “а.” To the naked eye, http://citibаnk.com appears identical to the real Citibank URL. This is what a homograph attack in cyber security entails. So, what is the most important aspect of a homograph attack? Its subtlety—the difference is nearly impossible to spot without careful scrutiny. Once you click the link, you’re taken to a fake site designed to harvest your personal information, passwords, or even install malware on your device.
