This course takes up where the CCNA videos on Access-Lists left off. Assuming that you are familiar with the basic concepts of Access-Lists, in this course you will learn about more advanced features of ACLs including; creative use of Layer-4 and Layer-5 matching options in ACLs, matching on TCP “established” flows, Reflexive ACLs, Dynamic ACLs, Time-Based ACLs, using Object-Groups within ACLs, and Access-List logging options.
https://wayland.freedesktop.org/
Wayland is a replacement for the X11 window system protocol and architecture with the aim to be easier to develop, extend, and maintain.
Wayland is the language (protocol) that applications can use to talk to a display server in order to make themselves visible and get input from the user (a person). A Wayland server is called a "compositor". Applications are Wayland clients.
Wayland also refers to a system architecture. It is not just a server-client relationship between a compositor and applications. There is no single common Wayland server like Xorg is for X11, but every graphical environment brings with it one of many compositor implementations. Window management and the end user experience are often tied to the compositor rather than swappable components.
Wayland does not restrict where and how it is used. A Wayland compositor could be a standalone display server running on Linux kernel modesetting and evdev input devices or on many other operating systems, or a nested compositor that itself is an X11 or Wayland application (client). Wayland can even be used in application-internal communication as is done in some web browsers.

Cobaltstrike UDRL with memory evasion
Feature :
• Redirect all WININET call over callstack crafting • Encrypt beacon during sleep • Encrypt beacon heap during sleep • Self delete of loaderExecution of loader:
1 - Create heap for beacon usage 2 - Allocation of RWX area with beacon size + UDRL size 3 - Copy the UDRL at the end of beacon in allocated area | 0x00 | beacon | 0xBEACON_SIZE | UDRL | 0xEND_Alloc 4 - Copy the ODIN structure (heap handle, beacon addr, alloc size) to the start of allocated area (no pe header is present) 5 - Copy beacon section 6 - Resolve beacon import and patch IAT (also set hook) 7 - Patch relocation table 8 - Init the beacon 9 - Create thread on TpReleaseCleanupGroupMembers+0x450 to spoof the thread start addr & beacon run 10 - Self delete the loader
