Here are few more important questions with detailed answers for malware analyst interview. Topic covers in this part is Dynamic analysis, static analysis and debugging.
All stuff you can do on linux
The risk of systems getting physically compromise, particularly portable systems such as laptops, puts sensitive data at risk of compromise. Encrypting its data mitigates the risk of getting exposure if system is lost.
If you want your hands on arm architecture assembly then you probably would be wondering how can I generate the *ARM* assembly or use ARM toolset in general inside my intel x86 or x64 architecture system. In this article we will explain you how you can do that by using qemu and chroot.
