Website mining
try Tencent computer housekeeper to protect the Internet environment. Relying on Tencent's huge proct ecological chain and user base, Tencent computer housekeeper has established the world's largest malicious website database, which is updated in real time through the cloud reporting platform. It has been at the leading level in the world in the fields of anti fraud and anti phishing, Therefore, it can achieve more accurate URL security detection in QQ platform, and prevent users from property or account loss caused by careless access to malicious URLs
in which you can query whether the open web links are safe
bitcoin is no longer easy to dig, and it is much cheaper than before
maybe you can only dig for a few hours a day and lose money
even if you mine with a high configuration computer in your own home, it is estimated that you will consume a little more electricity, not counting the aging depreciation of 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
2. Noise isolation the noise of mining machinery is not small at all, and the trusteeship of mining machinery is generally located in sparsely populated areas, which solves the problem of noise pollution
3. With more professional management and operation environment, mine machinery always has some problems. Mine trusteeship is generally operated by ihash with more professional operation and maintenance personnel.
Oh, it's also possible to run in the background (it's better to turn off the background first, and then exit)
