The great mischief. Working your way to the root flag through IPv6 labyrinths on a Hack the Box virtual machine

In this article, I will explain how to gain superuser privileges on Mischief VM available on Hack The Box training grounds. During this journey, you will acquire some SNMP skills, understand the IPv6 routing principles, and learn how to deal with the access control list (ACL) regulating the files and folders permissions. In the end, I will show how to write an ICMP shell in Python and test it.

Universal interception. How to bypass SSL Pinning and monitor traffic of any application

In many cases, the research of an app’s internal structure can be narrowed down to monitoring its traffic. Just a few years ago, a major share of the traffic was transmitted via the plain, easily interceptable HTTP protocol. By now, HTTPS has become the standard in most applications as a part of the defense mechanisms against eavesdropping. Today, I will try to explain what the different defense approaches have in common and whether their common component can be used to create a universal HTTPS interception technique.
