Adversary-in-the-Middle Attacks: How Phishing Sites Steal Your Active Login

You click a link, sign in, approve the MFA prompt, and get on with your day. Completely unaware that someone else just logged into your account at the same moment.

That scenario surprises many businesses, particularly those that rely on multi-factor authentication (MFA) to protect cloud accounts. But this is exactly how Adversary-in-the-Middle (AiTM) phishing attacks work.

Rather than stealing passwords for later use, these attacks silently hijack an already-authenticated session in real time.

MFA remains a core control, and getting it implemented correctly is still a critical first step for any business.

But AiTM attacks exploit something MFA was never designed to protect: the trusted session that exists after authentication has already completed.

The “Session Cookie” Hijack: Why MFA Can’t Always Save You

MFA is a strong front-door lock. But it’s not the only thing that decides whether someone can get in.

After you sign in, your browser keeps you logged in using a session token (often stored as a cookie). It’s the digital version of a wristband at an event: once you’ve been checked, the wristband proves you belong there. If an attacker steals that wristband, they may not need to beat your MFA prompt at all.

That’s the core of session cookie hijacking. The attacker isn’t “cracking” MFA. They’re skipping it by replaying your already authenticated session.

This isn’t a reason to stop using MFA. It’s a reason to stop treating MFA as the finish line.

When sessions can be stolen, the practical defence shifts to layered controls: phishing-resistant sign-ins, device hygiene, tighter session policies, and detection that catches suspicious access early.

Micro-SaaS Vetting: The 5-Minute Security Check for Browser Extensions

Browser extensions have a funny reputation. They feel “small”. A quick install. A tiny productivity boost. A harmless little helper that lives in your toolbar.

But in practice, a browser extension is more like a micro-SaaS vendor sitting inside your browser session. It can see what you see, interact with the pages you open, and sometimes access the same cloud apps your business runs on all day.

That’s why a browser extension security check matters.

Not because every extension is bad, but because it only takes one over-permissioned add-on or one bad update to turn “helpful” into exposure.

The good news is you don’t need a 40-page policy to reduce the risk. A simple five-minute check can prevent most extension problems before they start.

The Essential Security Checklist for Securing Company Laptops at Home

At home, security incidents don’t look like dramatic movie hacks. They look like stepping away from your laptop during a delivery, or leaving it unlocked while you grab something from another room.

Those ordinary moments, repeated over time, are how work devices end up exposed.

A remote work security checklist focuses on simple, practical controls that hold up in real life. Put it in place once, make it routine, and you’ll prevent the kinds of issues that hurt most because they were entirely avoidable.

The 2026 Guide to Uncovering Unsanctioned Cloud Apps

If you want to uncover unsanctioned cloud apps, don’t begin with a policy. Start with your browser history.

The cloud environment most businesses actually use rarely matches the one shown on the IT diagram. It’s built through countless small shortcuts: a “just this once” file share, a free tool that solves one problem faster, a plug-in installed to meet a deadline, or an AI feature quietly enabled inside an app you already pay for.

In the moment, none of it feels like a problem. It feels efficient. Helpful.

Until it isn’t. Then you realise business data is scattered across tools you didn’t formally approve, accounts you can’t easily offboard, and sharing settings that don’t reflect the actual risk.

Stop Ransomware in Its Tracks: A 5-Step Proactive Defence Plan

Ransomware isn’t a jump scare. It’s a slow build.

In many cases, it begins days, or even weeks, before encryption, with something mundane, like a login that never should have succeeded.

That’s why an effective ransomware defence plan is about more than deploying anti-malware. It’s about preventing unauthorised access from gaining traction.

Here’s a five-step approach you can implement across your small-business environment without turning security into a daily obstacle course.

A Small Business Roadmap for Implementing Zero-Trust Architecture

Most small businesses aren’t breached because they have no security at all. They’re breached because a single stolen password becomes a master key to everything else.

That’s the flaw in the old “castle-and-moat” model. Once someone gets past the perimeter, they can often move through the environment with far fewer restrictions than they should.

And today, with cloud apps, remote work, shared links, and BYOD, the “perimeter” isn’t even a clearly defined boundary anymore.

Zero-trust architecture for small businesses represents the shift that breaks that chain reaction. It’s an approach that treats every access request as potentially risky and requires verification every time.

5 Security Layers Your MSP Is Likely Missing (and How to Add Them)

Most small businesses aren’t falling short because they don’t care. They’re falling short because they didn’t build their security strategy as one coordinated system. They added tools over time to solve immediate problems, a new threat here, a client request there.

On paper, that can look like strong coverage. In reality, it often creates a patchwork of products that don’t fully work together. Some areas overlap. Others get overlooked.

And when security isn’t intentionally designed as a system, the weaknesses don’t show up during routine support tickets. They show up when something slips through and turns into a disruptive, expensive problem.

Zero-Trust for Small Business: No Longer Just for Tech Giants

Think about your office building. You probably have a locked front door, security staff, and maybe even biometric checks. But once someone is inside, can they wander into the supply closet, the file room, or the CFO’s office? In a traditional network, digital access works the same way, a single login often grants broad access to everything. The Zero-Trust security model challenges this approach, treating trust itself as a vulnerability.

For years, Zero Trust seemed too complex or expensive for smaller teams. But the landscape has changed. With cloud tools and remote work, the old network perimeter no longer exists. Your data is everywhere, and attackers know it.

Today, Zero Trust is a practical, scalable defense, essential for any organization, not just large corporations. It’s about verifying every access attempt, no matter where it comes from. It’s less about building taller walls and more about placing checkpoints at every door inside your digital building.

The Supply Chain Trap: Why Your Vendors Are Your Biggest Security Risk

You invested in a great firewall, trained your team on phishing, and now you feel secure. But what about your accounting firm’s security? Your cloud hosting provider? The SaaS tool your marketing team loves? Each vendor is a digital door into your business. If they leave it unlocked, you are also vulnerable. This is the supply chain cybersecurity trap.

Sophisticated hackers know it is easier to breach a small, less-secure vendor than a fortified big corporate target. They know that they can use that vendor’s trusted access as a springboard into your network. Major breaches, like the infamous SolarWinds attack, proved that supply chain vulnerabilities can have catastrophic ripple effects. Your defenses are irrelevant if the attack comes through a partner you trust.

This third-party cyber risk is a major blind spot, and while you may have vetted a company’s service, have you vetted their security practices? Their employee training? Their incident response plan? Assuming safety is a dangerous gamble.
