Global firm DLA Piper appears to have bounced back from a cyber-attack mid-way through last year, posting a strong set of results for 2017.

According to its global results for January to December last year the firm – one of the world’s largest by revenue and number of lawyers – posted a net profit of $709.1m (£504m), an increase of 10% from last year’s figure of $643m. Revenue increased by 6%, from $2.4bn to $2.6bn.

Equity partners also enjoyed an increase last year. Profit per equity partner rose 6%, from $1.65m to $1.75m.

In June, it was revealed that DLA had fallen to a cyber-attack targetting its computer systems and telephone lines. Reports last year said all telephones and emails at the 3,000 lawyer-strong firm were wiped out for two days. Complete access to emails was not secured for several days.

The attack, known as ‘Petya’, primarily targeted businesses based in Ukraine, Spain, France and Russia. Shipping company Maersk and food conglomerate Mondelez were among the companies impacted.

The firm declined to comment on whether the cyber-attack had any impact on its performance.

The firm did not provide separate figures for its UK operations.
