Alan Woodward Professor, Department of Computer Science, University of Surrey A major IT outage has hit businesses across the world, grounding planes as well as affecting banks and the healthcare sector.

Kevin Saric Computer Scientist & Mechatronic Engineer, CSIRO Our latest research has found that clickable links on websites can often be redirected to malicious destinations.

If we were able to find these vulnerabilities across the web,…
