Of all the key data in people's lives – health, personal and employment details to name a few – it is financial and banking information that is often the most prized by cyber-criminals. This information is a core commodity on the dark web and fuels organised crime across the globe, leading to record levels of bank robbery. Last year for example, security firm Kaspersky – working with Europol and Interpol – discovered that an international cyber-criminal gang from Russia, Ukraine and China had attacked up to 100 banks and financial institutions worldwide, stealing an estimated $1bn since the attacks started in 2013. © 2016 Elsevier Ltd
