What is a black swan event in cyber security?

A black swan event in cyber security is a rare, unexpected cyber incident with serious consequences — one that is only explained clearly after it has happened, even though warning signs may have existed beforehand. Examples include the WannaCry ransomware outbreak, the SolarWinds supply chain attack, and the MOVEit data theft campaign. These events were not impossible, but many affected organisations had convinced themselves the risk was too unlikely to act on.

Why do black swan cyber events matter to small businesses?

Small businesses often lack the monitoring, recovery planning and financial resilience of larger organisations. A serious cyber incident — ransomware, data breach or business email compromise — can cause extended downtime, lost income, regulatory investigation, reputational damage and insurance complications. The impact is often proportionally more severe than for a large enterprise.

Can a business prevent every black swan cyber event?

No. There is no silver bullet in cyber security, and no combination of tools can guarantee that every threat will be detected and stopped. What practical, layered security does is change what failure looks like. Instead of a catastrophic, business-ending incident, you get a contained event — one you can respond to, recover from and learn from. The aim is to reduce the likelihood of an incident and limit the damage if one does occur, through patching, multi-factor authentication, managed detection and response, email security and tested backups.

What is antifragility in cyber security?

Antifragility is a concept from Nassim Taleb's 2012 book Antifragile. Unlike resilience — which means surviving a shock and returning to the same state — antifragility means improving as a result of being tested. In cyber security, an antifragile organisation uses incidents, near-misses and tested response plans to become more capable over time. Good layered security supports this: it limits damage, generates learning, and produces evidence that helps with cyber insurance.

Is this QR code safe?

QR codes are useful, but they can also hide fake payment pages, lookalike websites, malware downloads and login traps. Before you tap open, pause and check where the code is really taking you.

QR code scam awareness

You scanned a QR code. That’s exactly how these scams start.

QR codes are useful, but they hide the destination until after you scan. Criminals use that moment of trust to send people to fake payment pages, copied login screens and malicious downloads.

! Before tapping open, read the web address carefully. Criminals rely on people rushing.

If you are not 100% sure, don’t act.

Why QR code scams work

A QR code hides the destination until your phone reads it. That makes it easy for criminals to send people to a fake website that looks real. Parking meters, restaurant tables, posters, parcel notices and unexpected emails are common places where QR scams can appear.

The danger is not the square pattern

The danger is the page it sends you to. That page may ask you to pay, log in, install an app or enter personal details.

Public QR codes need extra care

A sticker placed over a genuine QR code can redirect people to a scam site. If the code looks added, damaged or tampered with, avoid it.

Short links make it harder

Shortened web addresses hide the real destination. If you cannot tell where the code is taking you, go to the company website yourself instead.

How to check a QR code before you trust it

You do not need to be technical. You just need to slow the moment down and check the basics before tapping, paying or logging in.

✓

Ask where it came from Was it on a public sign, a sticker, a random leaflet, an email or a message you were not expecting?

✓

Inspect the code first Look for another sticker underneath, rough edges, odd placement or signs it has been added later.

✓

Preview the web address Most phones show the destination before opening it. Read the domain carefully, letter by letter.

✓

Avoid shortened links If the link is shortened and you cannot see the real destination, go to the company website yourself instead.

✓

Be careful with payment pages If a scanned code asks for card details, close it and use the official app or type the website manually.

✓

Do not install apps from a QR code Use the official Apple App Store or Google Play Store. A QR code should not pressure you into installing anything.

The real risk is not just the QR code. It’s what happens next.

A fake login page can lead to a stolen Microsoft 365 account. A malicious app can expose data on the device. A payment scam can lead to financial loss. A personal phone used for work can become part of a business incident.

Your team’s phones are part of your cyber security risk

Staff use mobiles for email, Microsoft 365, Teams, banking, WhatsApp, photos, files, MFA prompts and customer messages. That means a malicious QR code is not just a phone problem. It can become an account compromise, data breach, payment fraud or malware incident.
