Mining virus server
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
engine, so it can remove all kinds of stubborn Trojan viruses
the complete removal process of mining virus is as follows, please do it when the network is disconnected:
1. Stop and disable the hyper access protection agent service 2 3. Delete C: \% windows \% system32 \% vmichapagentsrv.dll. If the deletion fails, you can rename the file to another name 4. Restart the computer 5. Delete the directory C: (Windows) system32 (Sysprep themes) and C: (Windows) Sysprep themes 6. Delete C: / / Windows / system32 / secupdatehost.exe 7 https://docs.microsoft.com/zh-cn/security-updates/Securitybulletins/2017/ms17-010 8
our company is similar to you, just print some forms! Simple document, A4 format. I recommend Canon ip1000 printer, I bought it last year, 399 yuan in Changchun Science and technology city. The effect is good, or double ink cartridge (a black and a color) the main thing is to print very fast! It's the first time I've seen such a fast inkjet! ha-ha! Consumables are also cheap, not commonly used color, black original ink cartridge about 40 can be done.
Open the task manager with Ctrl + Alt + delete to see if there is any abnormal process. Temporarily use CPU
in addition, you can download and install 360 security guard to open anti mining protection, effectively intercept, and use Trojan horse to check and kill comprehensively
2. Install a computer manager on the computer, and then use the virus to check and kill the virus on your computer
