Monroe can solve these privacy problems by automatically applying confidentiality technology to every transaction. You can rest assured that you can't have a "contaminated" Monroe. This is an economic concept, called "interchangeability", historically considered to be an important feature of all currencies
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
Graphics card digging Monroe is really better than other currencies, the income will be higher! Of course, digging eth is also a good choice
this is my own video card miner. The mining software uses ha Yu miner , (the reason why I choose this software is that ha Yu does not pump water ) there are about 12 pieces per day

nmap - p0-65535 target IP address
common scanning types:
1, - SP (Ping scanning, checking whether the host is online or not, not sending any message to the destination host, want to know whether the target host is running, and do not want to do other scanning, which is very common)
2 -SL (only list the status, port and other information of the outgoing host in the network segment, use - P port, port1...) to query the port
3, - PS / PA / PU [portList] (use TCP or UDP packet detection according to the given port: for root user, this option allows nmap to scan the target host using syn packet instead of ACK packet. If the host is running, it will return an RST packet (or a sync packet))
4, - SS (TCP sync scan): issue a TCP sync packet (SYN), and then wait for it to return to the other party should)
5, - SF - Sn (secret fin packet scan, Xmas tree, null scan mode) - SF, - SX or - Sn scan shows that all ports are closed, Using syn scan to display open ports, you can determine that the target host may be running a Windows system
