When the Threat Isn’t a Hack: The Quiet Risks Undermining Promotional Campaigns

With major retailers like Co-op and M&S recently targeted by hackers — and the attackers even sending stolen data to the BBC to prove it — it’s never been clearer that digital vulnerabilities are a brand-wide concern.

But while those stories focus on server breaches and leaked data, there’s another, quieter threat growing in the background: entry form abuse. And it's not always bots.

In promotional marketing, particularly campaigns with web-based entry mechanics, we’re seeing a rise in semi-automated or even manual exploitation — where individuals or groups bypass basic checks to submit fraudulent entries, over and over again.

It’s not flashy. It’s not always fast. And it’s often not detected — until it’s already impacted your prize pool, campaign integrity, or reporting.

The New Face of Risk

What makes this so challenging is that it doesn’t behave like a traditional hack. There's no breach of your server. No compromise of your customer data. The infrastructure can be perfectly secure — and yet the campaign can still be at risk.

This type of abuse targets the front-facing forms that promotions rely on — forms that must remain publicly accessible in order to be compliant, convenient, and consumer-friendly. And that’s exactly what makes them vulnerable.

Why Traditional Tools Don’t Always Catch It

You might already be using:

• reCAPTCHA v2 or v3

• Basic form validation

• Email and phone number checks

• Firewall protection and secure servers

…and still find yourself dealing with suspicious entries that pass through unnoticed.

That’s because some attacks now involve:

• Catch-all email domains

• AI-assisted autofill

• Realistic (but randomly generated) contact details

• Human-assisted processes that mimic genuine behaviour

In short: it’s harder to detect because it doesn’t look suspicious — until the patterns begin to emerge.

What Can Brands Do?

There’s no silver bullet — but there are smart, scalable ways to reduce risk without hurting user experience.

1. Layer Your Security

One tool won’t do it. Combine reCAPTCHA with conditional logic, behavioural checks, or even simple frictions like one-time codes. The more steps an abuser has to complete, the more chance you have to spot and stop them.

2. Treat Data Collection as a Security Decision

Don’t just ask what’s needed for marketing — ask what might help flag suspicious patterns. The right data points can be your early warning system.

3. Be Cautious with Prize Value

The bigger the prize, the bigger the risk. Cash, tech, and luxury experiences attract a different level of attention — and sometimes exploitation.

4. Monitor Behaviour, Not Just Fields

Repeated patterns, high entry frequency from obscure email domains, or odd timestamp trends can tell you more than format validation ever will.

5. Secure Your Infrastructure — Always

While these attacks might not target your server directly, your database still needs to be protected. Data should always be hosted on secure, firewall-protected servers with limited access.

It’s Not Just a Tech Issue — It’s a Brand One

Whether it’s bots, humans, or something in between, entry form abuse undermines trust, skews performance, and creates unnecessary risk.

As marketers, we’re used to thinking about mechanics, engagement, and reach — but increasingly, we also need to think like security teams.
Because the next attack might not be on your data — it might be on your prize pool.
