About this page

This page describes a case where targeted attack emails caused a corporate data breach. An employee unknowingly opened a malware-infected email disguised as coming from an acquaintance, infecting their work computer. The malware collected sensitive organizational information and transmitted it externally. Response measures include isolating the infected device, investigating damage scope, removing malware, and notifying relevant parties. Prevention strategies include implementing email filtering solutions, deploying unauthorized communication detection systems, and conducting targeted attack email training to raise security awareness among employees.
