  • Smurf Attack

    A Smurf attack is a type of Denial-of-Service Attack (DOS) where an attacker exploits internet control message protocol (ICMP) packets. The attack surfaces when an attacker sends a massive flood of spoofed ICMP echo_request packets to the target victim.

    This article will learn about how a Smurf attack is executed and how much damage a Smurf attack can cause to a network. The article will also describe preventive measures against a Smurf attack.

  • MAC Flooding Attack

    A data link layer acts as a medium for communication between two directly connected hosts. At the sending front, it transforms the data stream into signals bit by bit and transfers it to the hardware. On the contrary, as a receiver, it receives data in the shape of electrical signals and transforms them into an identifiable frame.

    MAC can be classified as a sublayer of the data link layer that is accountable for physical addressing. MAC address is a unique address for a network adapter allocated by the manufactures for transmitting data to the destination host. If a device has several network adapters i.e., Ethernet, Wi-Fi, Bluetooth, etc., there would be different MAC addresses for each standard.

    In this article, you’ll learn how this sublayer gets manipulated to execute the MAC flooding attack and how we can prevent the attack from happening.

Games: Proton, Neptune 15 v2, and VR

  • What is Proton? | TechRadar

    You may have seen lots of mentions of Proton with the upcoming launch of the Steam Deck handheld game console, but what is it, and how does it work? Proton is a piece of software created by Valve and CodeWeavers that acts as a compatibility layer that allows games designed for the Windows 10 and Windows 11 operating systems to run in Linux with a minimal impact on performance. Proton is based on the existing WINE tool, which allowed Windows applications to run in Linux, with Valve and CodeWeavers taking the tech and using it to specifically run games. This is incredibly useful, as the vast majority of games are coded for Windows, due to the sheer popularity of Microsoft’s operating system. Linux, a free and open-source operating system, is relatively niche, which meant that many game developers couldn’t – or wouldn’t – spend resources on making a port of their games to run natively on Linux.
