Dear business partners

Following the cyber-attack, some may try to take advantage of the current situation and contact Hydro’s partners, pretending to be Hydro. This may be an attempt to spread the virus further or deceive our customers, suppliers or other partners. We therefore ask our partners to show extra caution when receiving emails from Hydro during this period. For instance, please note that Hydro is not under any circumstances asking our partners to change bank accounts. Anyone who is in doubt about the credibility of an email from Hydro should call the sender to verify. Contact your Hydro representative if you have any questions.
