Malware threats have been impacting the way that companies make and protect their business. In general, most of companies have bought several different products to compose their infrastructure and defense line, but they are only efficient against known and simple threats. Curiously, most infections start through simple vector such as a malicious document or a simple fishing. However, the problem is another one: what kind of malware a simple dropper can download in the system? Most ring 3 threats are visible, but some of them are not. Additionally, ring 0 threats are usually very dangerous because they work under the radar, compromising deeply the system and bypassing my protection. Worse, they can make the monitoring tools useless and open the way to advanced threats like BIOS/UEFI malware. What kind of techniques are used by these threats? What protections do we have? This presentation aims to show and explain some techniques used by malware advanced threats and protections against them.
