Control broiler mining
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
if you ask Yang, many enterprises are instrial now. It is the information age. Of course, the development of enterprises should keep up with the pace of the times, and improve the efficiency of enterprise operation to survive the fittest. For example, excel statistics and even manual records are now replaced by software, and data are not recorded on computers or even paper documents, but are now stored in servers. Now there are cloud computers. From 2G era to 3G to 4G era, the times are developing, and enterprises should keep pace with the times
now it's just that the degree of informatization of each enterprise is different.

tiktok provides a flow pool for every work, whether you are a large size or not, and how the quality of the work is. Your later communication effect depends on the performance of your works in this flow pool
this is decided by the platform recommendation algorithm, and it is also the data index pursued by all the playing methods< br />
2、 The flow of the voice and voice pool is divided into several levels:
8 flow pool
first exposure 300 playback
two times recommendation 3000 playback
three times recommended 1.2-1.5 universal right play volume
four times 10-12 10-12 right play volume > five / five recommended 40-46 million right play volume > six / six recommended tiktok right volume, seven, recommended seven million right broadcast Volume
Top recommended 30 million + right playback
3 How to use the flow pool
how to enter the next traffic pool:
indicators:
point ratio: 5-10%
attention ratio: 0.8%
comment ratio: 1%
: > / / > cold start flow quantity is effective. The current algorithm is the three tiktok recommendation, manual audit before, and label verification. After four times of recommendation, the content (sensitive words, illegal words) is audited by machine
the completion rate is the basis of all the above data, and the playback amount is calculated based on the complete playback
