Danish pump maker DESMI said on Friday it was busy restoring its IT systems after suffering a cyber hacking attack earlier this week.

“At present, the scale of eventual data loss is being investigated and it is yet too early to communicate the impact of the attack,” the company’s chief executive Henrik Sorensen said in a press release on 10 April.

Customers and business partners will receive operational updates as soon as possible.

The unidentified hackers attacked on the night to Thursday, 9 April. Systems are being restored after a shutdown and will be gradually recovered from Sunday onwards within a period of two weeks, DESMI said.

Danish police and other authorities are on the case.

European police and cyber security agencies have warned in recent weeks that as white-collar workers are increasingly employed from home amid the Covid-19 crisis, companies’ IT systems will become vulnerable to internet attacks.

“Malign actors are actively exploiting these new challenging circumstances to target remote workers, business and individuals alike,” Europol and the European Union Agency for Cybersecurity (ENISA) said in a joint statement on 20 March.

DESMI was largely in remote-work mode when the attack happened. The company's external experts, however, are concluding that this circumstance played no role in the incident.

“The attack could have happened even if everybody was in the office,” Sorensen told TradeWinds by phone.

According to its website, which seems to be fully functioning, DESMI was founded in 1834 - making it one of Denmark’s oldest companies. The firm posted revenues of DKK 1.556 bn ($228m) last year.
