How will the server be invaded by mining Trojan horse
to prevent viruses from entering the computer
a new customer recently consulted with sine security company, saying that his server often fails to open the website of the card, and the remote connection to the server is extremely slow. Sometimes the Ping value reaches 300-500, and he often switches. After listening to the customer's words,
will generally judge that he has been attacked by CC + DDoS mixed traffic, It's strange to say that there is no traffic attack on the computer room. It's not a traffic attack, but it also causes the server card and website to fail to open. What kind of attack is this? In order to solve the problem of
client server card, we immediately arranged a security engineer to carry out security detection and deployment on his Linux server
{rrrrrrr}
mining Trojan horse is also designed. If the mining process is forced to stop by customers, it will automatically start to continue mining to achieve uninterrupted mining.
careful inspection shows that it is through setting the hourly task plan, remotely downloading shell mining Trojan horse, and then executing, Check whether the current process exists or not. If not, start the Trojan horse to mine
a detailed security inspection was carried out on the client's Linux server. It was found that fortunately, there was no encrypted server data, and the worm was infected with the disease through the security detection and analysis of our security engineers, we found that the server uses Apache Tomcat environment, the open architecture of the platform is JSP + Oracle database, and Apache Tomcat uses the version of 2016, which leads to the serious remote command execution vulnerability of Apache, Through this vulnerability, the intruder can directly invade the server and get the administrator permission of the server,
virus. If the data was encrypted, the loss would be great. The client was a platform, and the client's data was very important. After finding out the mining Trojan horse,
do customers need to know how the server is attacked? Was the Trojan horse uploaded? It can prevent the attack
in the later stage
sine security engineer immediately repairs the Apache vulnerability and clears the Trojan horse. So far, the problem has been solved, the client server
runs stably, and the network station opens normally
Download Tencent computer manager and turn on the real-time protection function
once you browse the virus webpage or download the virus software, you will give a security warning
if there is a virus invasion, you can immediately prompt and kill the virus
if you have to check, it's also simple. You can see if there are unusual system processes
however, you can't deal with your own security thoroughly. It's better to find a professional security company (such as guardian).
at present, the application scenarios of digital RMB are not extensive. It's only in the pilot stage. I think it will be promoted graally with the development of economy in the future, and it can also promote the development of economy in the future at present, many banks in our country are actively promoting the use of digital RMB, and the contribution of RMB plays a supporting role in our country's economy. Digital RMB will not only get a lot of use scenarios in our country, but also play a more important role in international trade
in fact, we have already felt the convenience in the process of using Alipay and WeChat to pay. In fact, the digital RMB has more advantages than the two payment methods, and its functions are more complete. so I have reason to believe that digital RMB can be further promoted. It's just a matter of time
According to the description of the title, my first reaction is that you did not resolve the domain name
1. You can resolve the domain name through the domain name provider you purchased
for example, alicloud (Wannet), you can directly log in to the domain name proct in alicloud console, click manage to enter the background
and directly select the domain name to bind< br />
