The danger of chatting depends on common security problems of Instant Messaging

The Instant messaging tool (IM) is one of the most widely used network applications. After QQ's little penguin icon appeared on our computer at an astonishing speed, well-known vendors such as Netease, Sina, and Sohu could not wait to join the competition, microsoft, Yahoo, and AOL have never stopped their expansion.

The instant messaging platform is truly closer to people around the world. It is an indispensable communication tool for both individual and enterprise users. Today's instant messaging tool not only enables text chat, but also transfers files between two computers and communicates audio and video.

It is precisely because of the high speed and popularity of instant messaging applications that make security attacks have a great space for development and damage capabilities. Rich features are one of the main ways instant messaging attracts users. However, from a security perspective, the regionalization of functions is just contrary to strict security rules. As an application system to maximize communication capabilities, its authentication mechanism and protection measures are relatively weak, which is easily exploited by malicious attacks. Next, let's take a look at the security problems faced by the instant messaging application system in several aspects.

IM system problems

Before discussing other issues, let's take a look at the potential damages caused by attacks on the instant messaging system. The first is the infrastructure of instant messaging, such as servers that store all data transmitted and communication records. Once attacked, records of tens of thousands of users will be exposed to attackers. Even though all instant messaging service providers remind their users not to use instant messaging to transmit sensitive information, these records still contain a large amount of passwords and important information. In addition to the server of the service provider, users' personal computers also store a large amount of such information.

Compared with the formal security measures on the server, data on personal computers is more likely to be stolen. The theft of information will not only cause economic losses to users, but also cause the privacy crisis. In addition to the security risks at both ends of the communication, because instant messaging tools usually use weak encryption or even non-encrypted data transmission methods, network eavesdropping also poses a great threat to the instant messaging system.
