In the AV Evasion feature of this month, you will learn about a tool that is currently being used by Black Hat Hackers around the world to evade Antivirus and Endpoint Detection and Response (EDR).

This tool was inspired from another tool called FireBlock from md5sec’s Night task. Before you understand how this tool works, you need to understand some basics. Let’s start.…

Jongkil Jay Jeong Senior Research Fellow in the School of Computing and Information System, The University of Melbourne Despite huge advances in cyber security, one weakness continues to overshadow all others: human error. Research has consistently shown human error is responsible for an overwhelming majority of successful cyber attacks. A recent report puts the figure at 68%. No matter how advanced our technological defences become, the human element is likely to remain the weakest link in the cyber security chain. This weakness affects everyone using digital devices, yet traditional cyber education and awareness programs – and even new, forward-looking laws – fail to adequately address it. So, how can we deal with human-centric cyber security related challenges? Understanding human error There are two types of human error in the context…
