One click can close a small business, warns cyber expert

Artificial intelligence is putting the North's SMEs in the firing line of online criminals as automated attacks reshape the threat landscape, a leading cyber security expert has warned.

Derry-born Robbie O’Brien, co-founder of Safe Harbour Security, says AI has tipped the balance decisively in favour of criminals, making smaller firms the softest targets in an increasingly automated cybercrime environment.

Mr O’Brien made the comments ahead of  seminars in Derry (register here) and Belfast (register here) to help local business leaders understand how the rules of cybercrime have changed — and what they can do about it.

“AI has lowered the skill barrier, increased scale, increased precision, and removed the human error that used to expose scams. It has effectively turned cybercrime into a mass-production system,” Mr O’Brien explained.

He warned that cybercrime was no longer "limited to highly skilled operators, nor does it require the time it once did".

“AI tools now enable organised groups to generate convincing phishing emails, impersonation fraud and ransomware campaigns at speed and at scale," said Mr O'Brien.

“We are facing adversaries who are better funded, better organised and more technologically enabled than ever before. For a small business, that is a very uneven fight," he added.

"Many SMEs are facing that fight alone. “The reality is that SMEs are on their own. Government agencies are stretched and can barely protect their own systems. Small businesses cannot assume someone else is going to step in.

"Many SMEs are still relying on outdated assumptions about what an attack looks like. There was a time, for example, when phishing emails stood out because the language was poor. AI has removed that weakness. The old advice to ‘just look carefully’ is no longer enough.

"The result is a constant stream of automated attempts targeting businesses of every size.

“The volume of automated attacks is increasing weekly. Many SMEs don’t realise they’ve already been targeted. Most only discover their vulnerabilities after an incident," said Mr O'Brien.

"For large organisations, breaches can be costly. For smaller firms, they can be fatal," he added.

“For many SMEs, one successful attack is all it takes. Cashflow stops. Systems go down. Reputation is damaged. Cyber security isn’t a discretionary spend — it’s operational survival.”

Explaining why his team at Safe Harbour Security is hosting ‘Cyber Security For Dummies — The SME Survival Briefing’ events in Belfast and Derry, Mr O’Brien said: "We’re running these free briefings because too many SMEs feel overwhelmed or unsure where to start, and we have the answers. Business leaders need clarity, not jargon — and that’s what we’re aiming to provide.”
