"Another pat on the cloud" may be a problem??

When I visit some websites these days, Avast often appears to block malicious websites as follows:

Where is this aicdn.com? How many sites will use this?

Check this domain name on Baidu, the result is as follows:

650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M00/58/D3/wKioL1S9_pCj6i75AAOtVjQlBaw548.jpg "style=" float: none; "title=" 22.png "alt=" Wkiol1s9_pcj6i75aaotvjqlbaw548.jpg "/>

As can be seen from the query, this aicdn.com is a cloud-owned CDN domain name.

Here I have a little bit of technical ability, after a rough analysis, it is estimated that there are two things that can happen:

First case

Someone hacked and patted the cloud storage system, and every user who patted the cloud would call some malicious code, and each access was accelerated by the Aicdn.com CDN System. Some security software will find that all aicdn.com domain name address will be wrong, so that all aicdn.com URLs are containing malicious code. (This may be a big one, just imagine, break a CDN system, all the malicious code in the whole network to accelerate ~~~~~ really cool ~~! And the CDN system has more than 500 nodes server Ah! This break one, get a large group AH ~ ~ ~ ~ ~ ~. Is there a new change in the target of hacking in 2015? haha

The second case

Also patted the cloud of the customer may be (or be uploaded) some malicious code files, and then pat the CDN system may be provided by the same service domain name (that is, everyone has the same domain name access and Pat CDN System, the feeling of this bull company, should not have only one domain? ）

Disclaimer: I am not technically good, this article is only in the circumstances of my personal ability to carry out the analysis, does not represent the actual situation of the problem. If there are any experts have different opinions or know the true like, you can leave a message and I exchange, thank you!
