Shlomi Boutnaru is the CTO and co-founder of predictive cyber-security startup CyActive. If 2014 did anything good for cybersecurity, it showed us just how exposed major corporations, governments and militaries are to cyber attacks. From vulnerabilities in our power grids to our cash registers, cyber attacks have become the $400 billion problem. And while the attacks differ in motive and method, there are four consistent perpetrators charging at us at full speed – and we need to rein them in. These “Four Horsemen” point us to the components we can expect to see used by hackers in 2015: exploits in unpatchable systems; recycled malware hidden imperceptibly; and human error. Studying these harbingers could very well save us from a potential cyber catastrophe.
