The cause of Steam's failure was announced last night: DDoS attack, unrelated to the number of online users of "Black Myth"

However, according to the announcement released by the Perfect World Athletics platform, the Steam crash was caused by a DDoS attack.

It is understood that a DDoS attack refers to a distributed denial-of-service (Distributed Denial of Service), in which an attacker uses one or more computers in different locations to launch attacks on one or more targets simultaneously, consuming target server performance or internet bandwidth.

A type of cyber attack that causes a server to run slowly or go down, causing it to fail to provide service properly.

For example, this attack is like a group of people coming to a restaurant, but they don't order, causing other customers who really want to eat to be unable to order, and the restaurant loses customers and revenue.

It is reported that there are various ways of DDoS attacks, including SYN flood attacks, UDP flood attacks, DNS flood attacks, and DNS amplification attacks.
