Picture this: A company hands over its floor plans, employee directories and network details to a group of total strangers, then tells them to try and break in. Staff don’t get warned and the IT department has no clue. There’s just a quiet contract signed behind closed doors and a start date scribbled on a calendar.
Businesses across the UK are actually paying professional hackers to attack them on purpose, and there’s a very good reason for it. What goes on during one of these secret break-ins, and why does nobody inside the company know it’s happening until it’s already over?
The Job Nobody’s Supposed to Know About
In the industry, they call these red team exercises. A group of certified security specialists gets hired to simulate a real attack against a company, and they’ll use the exact same methods an actual criminal would. We’re talking phishing emails written to fool specific employees by name, phone calls designed to sweet-talk passwords out of people, and sometimes even physical attempts to stroll through the front door with a cloned badge or a borrowed lanyard.
Nobody’s trying to cause damage here. The whole point is to find out how far a determined attacker could get before a single person notices something’s off. And the company’s own security team? Completely in the dark. If the defenders knew it was coming, you’d lose the entire point of the exercise.
Fake Emails, Real Consequences
Most operations kick off with reconnaissance. The hired team will spend days or even weeks studying the company from the outside, picking apart public LinkedIn profiles, company press releases and even bin bags left outside the office. Every scrap of information feeds into a profile that helps them build attacks that actually look convincing.
A properly crafted phishing email won’t resemble spam in any way. It’ll reference a real project, drop a real colleague’s name and land in someone’s inbox at the perfect moment. One careless click on the wrong link gives the attackers a foothold inside the network. From that point on, they’ll move quietly through internal systems, climbing their way up the access ladder until they reach whatever target the company set for them, whether that’s a customer database, a financial system, a boardroom file share or some other sensitive asset.
Who Actually Does This Work?
This kind of work takes a very specific skillset. Certified specialists like Omni’s red team experts will typically spend weeks acting as a determined criminal, testing people and physical premises alongside computers and networks.
These aren’t hobbyists poking around with off-the-shelf tools. They hold industry accreditations, operate under strict legal agreements and follow recognised frameworks like MITRE ATT&CK to structure every stage of their attacks.
What Happens When They Get Caught (or Don’t)
Sometimes the internal security team spots something suspicious and shuts it down. That’s a genuine win, because it proves the company’s defences can hold up when it counts. But more often than you’d think, the red team gets further than anyone expected, and that can be a bit of a shock.
The gap between what a business believes is secure and what actually survives a targeted attack is exactly why these exercises exist in the first place. Once everything wraps up, both sides sit down together and the attackers walk through exactly what they did, how they got in and where the defences crumbled. It’s uncomfortable. Nobody enjoys hearing that their carefully built security setup got picked apart in a few days. But it gives the company an honest, unfiltered picture of what a real breach would look like, and that’s something no audit report or compliance checklist can replicate.
Why More UK Businesses Are Paying to Be Attacked
The logic behind all of this is pretty simple. A company can either find out where its weaknesses are from a team it hired and controls, or it can find out from a criminal who didn’t bother asking permission first.
For any business that handles sensitive data or operates in a regulated industry, paying someone to break in on purpose might sound extreme, but it’s probably the most responsible security decision they’ll ever make.
