Hack attacks seen as wake-up call for Danish companies

The recent wave of hacking attacks on refrigeration and air conditioning systems in Europe and Denmark may be the beginning of a new wave of cyber attacks, according to experts.

The attacks, which affected several European and Danish companies, are a serious wake-up call, says Jacob Herbst, an expert.

Companies may not be prepared for the threat, Herbst warns, as they are not necessarily equipped to handle the attacks.
