One in five firms that pay ransom fail to get their data back, according to new research from Trend Micro.

A poll of IT managers at 300 UK businesses sponsored by Trend Micro found that 44 per cent of UK businesses have been infected by ransomware in the last two years.

The study also found that around two-thirds (65 per cent) of UK companies confronted with a ransomware infected end up paying out in the hopes of getting their data back.

The average amount of ransom requested in the UK was £540, although 20 per cent of companies reported ransoms of more than £1,000. The majority – 57 per cent of companies – reported having been given under 24 hours to pay up.

Organisations affected by ransomware estimate they spent 33 person-hours on average fixing the problem.

The ransomware problem is growing. Trend Micro has identified 79 new ransomware families so far this year, compared to 29 in the whole of the 2015.
