The software supply chain saw a 51 per cent increase in cyber attacks in 2021, according to a new report. Large-scale attacks, like SolarWinds and Kaseya, made the headlines – but were single examples of a problem affecting thousands of companies. Attackers targeted supply chain firms for the publicity and large-scale disruption on offer. Where normal companies will see an attack confined only to their services, supply chain software has the potential to travel down the line to customers and partners. According to the report, supply chain companies have increased their IT defence budget by around 10 per cent to address security.
