Cybersecurity

When your router becomes a hacker's target. An attack on your Wi-Fi network is nothing like the bank heist you've seen in films: instead of masked criminals blowing open a vault with explosives and a great deal of noise, a modern hacker approaches your router quietly — a digital ninja feeling for weak points, probing multiple paths of entry. Or they exploit a known security flaw, launching a surgical strike against a router they've already identified and prepared for.

Because you can never know when or where your router will find itself in an attacker's crosshairs, you should always ensure that the device is hardened against intrusion. Raise your router's level of protection through proper configuration, so that any attack becomes too costly and frustrating to be worth pursuing — as though you've transformed your home into a digital fortress. And make a habit of reading up on newly discovered vulnerabilities, so that you can close them promptly with firmware updates.

What follows is a guide to the most dangerous and most common attacks on Wi-Fi networks, along with practical advice on how to defend yourself effectively. By the end, you'll have a ready answer to each type of attack — and you'll be able to secure your router and home network in just a handful of simple but crucial steps.

Why Hackers Attack Wi-Fi Networks: The Motivations Behind the Attacks

To attack a Wi-Fi network, hackers target either the wireless connection between a client device and the router (like a spy listening in on a conversation) or the router itself (like a burglar picking the lock on a front gate).

With the first strategy, attackers set out to record the data that devices exchange over Wi-Fi. In doing so, they can either guess the Wi-Fi key and join the connection, or redirect traffic to their own servers. Either way, they gain access to sensitive information: passwords for online banking, credit card details, social media credentials. These can then be used personally for financial gain or sold on underground markets to other hackers.

The radical transformation of the digital fraud landscape. I often think, in those late hours when the glow of a screen becomes the only window onto a world that never sleeps, about how it would feel to watch your own identity peel away from your body and travel through networks and digital systems — acting independently, without your consent, without your knowledge. In 2025, that strange, almost surrealist image became reality for millions of people. Sumsub's report, based on the analysis of more than four million attempted digital frauds, documents a 180% increase in sophisticated attacks compared to the previous year. This is not about more attacks. It is about a fundamentally different kind of attack.

What struck me when I read those figures — sitting at my desk on a grey November afternoon — was not their magnitude but their deeper meaning. We have moved out of the era of high-volume assaults, those hundreds of thousands of messages cast randomly into the world in the hope that someone would take the bait, and into a world where every strike is meticulously prepared, aimed at precisely the right person at precisely the right moment. It is as though digital violence has evolved from carpet-bombing to laser-guided precision strikes.

I wondered then — and I still wonder now — whether the teenagers I speak with, those who are born already with fingers shaped for touchscreens, truly understand what this shift means. For them, the digital world is as real as the air they breathe. But air can be poisoned without warning, until it is too late. And that is what is happening: the poison is becoming more refined, harder to detect, more lethal.

The Silent Farm: Bots, Public Perception, and the Invisible Beneficiary

There is a moment when a number stops being a statistic and becomes a symptom. That moment, as far as the internet is concerned, has already passed. It passed without newspaper headlines, without political declarations, without any institutional response remotely proportional to its gravity.

In 2024, for the first time in a decade, automated traffic surpassed human activity online. More than half of everything circulating on the internet — 51 per cent, according to Imperva's annual Bad Bot Report — was produced by no human hand, observed by no human eye, driven by no human intention. It was produced by machines that imitate people. Machines that comment, distribute likes, create accounts, spread messages, simulate consensus, and construct — with the tireless patience of a mechanism that never sleeps — a parallel reality in which no one knows with any certainty who they are actually talking to.

This is not a metaphor. It is a cybersecurity report. And its implications extend far beyond the world of IT.

Before 51%: How We Got Here

The internet was not born with bots. It was born with people who dreamed of a global network of knowledge — a space where ideas might travel freely and conversation transcend borders. The first bots arrived quietly, in the shadow of that dream: simple programmes that indexed pages, dispatched automated notifications, responded to elementary commands.

They were tools. Neutral, in principle.

The transformation was gradual. Social media platforms came to understand that engagement — not truth, not the quality of conversation, but raw emotional reaction, any form of activity at all — was their currency of exchange. And once someone grasped that bots could generate engagement on an industrial scale, they became instruments of power.

By 2023, nearly half of all global internet traffic — 49.6 per cent, according to the same Imperva research — was already coming from automated sources. The highest level recorded since the company began monitoring the phenomenon a decade earlier. A year later, the 50 per cent threshold was crossed. This trend is neither accidental nor reversible through individual vigilance alone.

I often wonder how I would explain it to my son — barely into his teens now, hours spent staring at his phone — what is actually happening in the depths of the internet he takes to be a safe place. How do you tell a child that whilst he checks his messages or downloads his latest app, somewhere in the hidden corners of the network, people are turning technology into a weapon? I don't want to frighten him. But I can't leave him defenceless, either.

And so I began writing this piece, thinking of him, of his friends, of all the adolescents growing up inside a digital world they don't fully understand. The year 2025 has brought with it an explosion of digital fraud so sophisticated it could serve as the backdrop for a film in the vein of William Gibson's Neuromancer or Blade Runner — worlds where the boundary between the real and the virtual blurs until it disappears entirely.

The Global Landscape of Cybercrime in 2025

When I look at the figures in this year's security reports, I feel a weight settle in my chest. The median cost of a security incident has risen from $190,000 to nearly $3 million over the past fifteen years. It is as though we are watching the inflation of a nightmare — one that worsens not gradually but exponentially. The IRIS 2025 report shows that extreme security events have grown roughly fivefold in financial impact, and I find myself thinking about all those small businesses, those family enterprises, those ordinary people who lose the savings of a lifetime to attacks they cannot even begin to comprehend.

Distributed denial-of-service attacks have reached dimensions without precedent. The attack on KrebsOnSecurity, for instance, peaked at 6.3 terabits per second. Try to hold that number in your mind: it is like trying to drink from a fire hose whilst you are already drowning. The Aisuru botnet, which I shall come to shortly, represents a tenfold escalation over the Mirai attacks of 2016. It is the evolution of a virus that keeps growing resistant to treatment.
