CNA's investigation reported that cyberattack group Phoenix had used Phoenix Locker malware, a variant of the Hades ransomware used by Russian criminal hacking group Evil Corp. [179] Phoenix Locker malware encrypted 15,000 devices on the network, as well as the computers of employees working remotely while logged into the company's VPN during ...
The problem in the running code was discovered in 1995 by Ian Goldberg and David Wagner, [4] who had to reverse engineer the object code because Netscape refused to reveal the details of its random number generation (security through obscurity). That RNG was fixed in later releases (version 2 and higher) by more robust (i.e., more random and so ...
Diagram on the execution and synchronization of the inputs of two players (with a 90 ms ping between them) in an online game that uses delay-based netcode in a peer-to-peer model. The classic solution to this problem is the use of a delay-based netcode.
A ping of death is a type of attack on a computer system that involves sending a malformed or otherwise malicious ping to a computer. [1] In this attack, a host sends hundreds of ping requests with a packet size that is large or illegal to another host to try to take it offline or to keep it preoccupied responding with ICMP Echo replies.
Low Orbit Ion Cannon (LOIC) is an open-source network stress testing and denial-of-service attack application written in C#.LOIC was initially developed by Praetox Technologies, however it was later released into the public domain [2] and is currently available on several open-source platforms.
Client-side prediction reduces latency problems, since there no longer will be a delay between input and client-side visual feedback due to network ping times. However, it also introduces a desynchronization of the client and server game states, which needs to be handled to keep the game playable. [ 1 ]
Simple remote control systems use a fixed code word; the code word that opens the gate today will also open the gate tomorrow. An attacker with an appropriate receiver could discover the code word and use it to gain access sometime later. More sophisticated remote control systems use a rolling code (or hopping code) that changes for every use.
