π¦WHAT IS ARP ATTACK & how to secure yourself ?
ARP attacks mainly exist in the local area network. If a computer in the local area network is infected with an ARP Trojan, the system infected with the ARP Trojan will try to intercept the communication information of other computers in the network by means of "ARP spoofing". It will cause communication failures of other computers in the network. Let's introduce the solution to the ARP attack on the computer.
π¦Computer suffers ARP attack, solution :
#FastTips
1. Turn on the built-in firewall of the system. In fact, the built-in firewall of the system can also cope with general ARP attacks! But few people use it. First click on the start menu and enter the control panel!
2. Select the "System and Security" option on the control panel page to enter,
3. In the system and security interface, choose to enter the check firewall status under the windows firewall!
4. On the windows firewall status page, click "open or close windows firewall" in the right menu
5. Open and close the firewall page, and turn on the firewall in all network environments!

π¦How to quickly remove the Trojan horse virus in the system ?
Clearing the DLL backdoor is
relatively file-bundled. The DLL insertion Trojan is more advanced, with no process, no ports, etc. It is difficult for ordinary people to notice. Therefore, the removal steps are relatively complicated.
The DLL insertion Trojan is more advanced, with no process, no ports, etc. It is difficult for ordinary people to notice. Therefore, the removal steps are relatively complicated.
1. End the Trojan horse process.
Since this type of Trojan horse is embedded in other processes, it does not generate specific items in the process viewer. If we find that our system is abnormal, we need to judge whether it has been hit DLL Trojan.
> Here we use the IceSword tool. After running the program, it will automatically detect the running process of the system. Right-click on the suspicious process and select "Module Information" in the pop-up menu. You can view all DLL modules in the pop-up window. At this time, if you find an item of unknown origin, you can select it, and then click the "Uninstall" button to delete it from the process. For some stubborn processes, we will also click the "Forced Release" button, and then use the address in the "Module File Name" column to delete them directly in the folder.
2. Finding suspicious DLL modules
As general users are not familiar with the calling of DLL files, it is difficult to determine which DLL module is suspicious. In this way, ECQ-PS (Super Process King) can come in handy.
> After running the software, you can see all the processes in the current system in the middle list. After double-clicking one of the processes, you can display detailed information in the "All Modules" tab of the window below, including the module name , Version and manufacturer, and time of creation, etc. The manufacturer and creation time information is more important. If it is a critical system process such as "svchost.exe", but the result is a module from an unknown manufacturer, the module must be faulty. In addition, if the manufacturer is Microsoft, but the creation time is different from that of other DLL modules, it may also be a DLL Trojan.
> In addition, we can also directly switch to the "Suspicious Module" option, the software will automatically scan the suspicious files in the module and display them in the list. Double-click the suspicious DLL module in the scan result list to see the process of calling this module. Generally, each DLL file is called by multiple processes. If this DLL file is only called by this process, it may also be a DLL Trojan. Click the "Forced Delete" button to delete the DLL Trojan from the process.
3. Thorough Rootkit detection It is
impossible for anyone to check the ports, registry, files, and services in the system all the time to see if the Trojan is hidden. At this time I can use some special tools for detection.

π¦practical methods to break through IDS intrusion detection system :
There are many kinds of polymorphic URL encoding technologies, and the author here introduces 9 commonly used and representative methods. For the convenience of explanation, here is the URL with the submission address /msadc/msadcs.dll as an example. "/Msadc/msadcs.dll" has been collected in snort and other major IDS rule set files, so when we directly submit /msadc/msadcs.dll to the target machine, it will be intercepted and alarmed by IDS.
The first trick: "/./" string insertion method
In view of the special role of "./", we can insert it into the URL to achieve URL transformation. For example, for /msadc/msadcs.dll, we can rewrite it as /././msadc/././msadcs.dll, /./msadc/.//./msadcs.dll and other forms to disrupt IDS The identification mark analysis engine realizes the purpose of deceiving IDS. Moreover, the URL after the rewrite is equivalent to the unmodified URL. The author has shown through experiments that this method can bypass IDS such as Snort.
The second trick: "00" ASCII code
Some time ago, the Internet upload vulnerability was used to exploit this feature, and everyone must be familiar with it. Its principle is that when the computer processes the string, it automatically truncates at the ASCII code 00. We can rewrite /msadc/msadcs.dll to /msadc/msadcs.dll Iloveheikefangxian, use Winhex to change the space between .dll and Ilove to the ASCII code of 00, save it, and then submit it with NC and pipe. In this way, in the view of some IDS, the /msadc/msadcs.dll Iloveheikefangxian is not the same as the string of attack intent specified in its rule set file, so it will be indifferent to the behavior of the attacker. Look! How extensive is the application of the principle of "automatically truncating at ASCII code 00 when the computer processes a string"! Philosophically speaking, things are connected with each other, we should think more and dig out the internal laws, so There will be new discoveries.
The third trick: use the path separator "\"
For web servers like Microsoft's IIS, "\" can also be used as a path separator like "/". Some IDS did not consider the non-standard path separator "\" when setting the rule set file. If we rewrite /msadc/msadcs.dll to \msadc\ msadcs.dll, we can escape snort, because there is no identification mark of \msadc\ msadcs.dll in the snort rule set file. It is worth mentioning that the path separator "\" also has a magical effect, which is the "%5c" violent library method mentioned in the "Hacker Line of Defense" some time ago. "%5c" is the hexadecimal representation of "\".
Fourth trick: hexadecimal encoding
For a character, we can use the escape symbol "%" plus its hexadecimal ASCII code to represent it. For example, the first character "/" in /msadc/msadcs.dll can be expressed as %2F, and the following characters can be expressed by their corresponding hexadecimal ASCII code combined with "%". The URL encoded by this method It is no longer the original appearance. There may be no encoded string in the IDS rule set file, so IDS can be bypassed. But this method is invalid for IDS that uses HTTP preprocessing technology.
The fifth trick. Illegal Unicode encoding
UTF-8 encoding allows the character set to contain more than 256 characters, so it also allows more than 8 bits of encoding. The hexadecimal ASCII code of the "/" character is 2F, and the binary number is 00101111. The standard method for representing 2F in UTF-8 format is still 2F, but multi-byte UTF-8 can also be used to represent 2F. The character "/" can be represented by single-byte, double-byte, and three-byte UTF-8 encoding as shown in the following table:
"/" character representation binary hexadecimal
Single byte 0xxxxxxx 00101111 2F
Double byte 110xxxxx 10xxxxxx 11000000 10101111 C0 AF
Three bytes 1110xxxx 10xxxxxx 10xxxxxx 11100000 10000000 10101111 E0 80 AF

Three bytes 1110xxxx 10xxxxxx 10xxxxxx 11100000 10000000 10101111 E0 80 AF
According to this method, we can encode the entire string accordingly. Although the resources that the encoded URLs ultimately point to are all the same, their expressions are different, and the filter string may not exist in the IDS rule set file, thus achieving the goal of breaking IDS.
Sixth trick: redundant coding method
The redundant coding is also called double decoding. I still remember that the Unicode decoding vulnerabilities and the double decoding vulnerabilities of IIS in 2000-2001 were making a lot of noise. At that time, many friends were confused and thought that the Unicode decoding vulnerabilities were double decoding vulnerabilities. In fact, the two of them are two different things. Is described in "Illegal Unicode Encoding". The redundant encoding refers to encoding a character multiple times. For example, the "/" character can be represented by %2f, and the "%", "2", and "f" characters in "%2f" can be represented by its ASCII code hexadecimal, according to the mathematical According to the knowledge of permutation and combination, the encoding form is 2 to the 3rd power, so "%2f" can be rewritten as: "%25%32%66", "%252f", etc. to realize the polymorphism of the URL. After encoding, The string may not be collected in the IDS rule set file, which can fool some IDS.
Seventh trick. Add false paths
After adding the string "../" to the URL, the directory after the string has no meaning and becomes invalid. Therefore, using the "../" character string can disrupt the identification mark analysis engine and break through the IDS!
Eighth trick: insert multiple slashes
We can use multiple "/" instead of a single "/". The replaced URL will still work as before. For example, the request for /msadc/msadcs.dll can be changed to ////msadc////msadcs.dll. After the author has experimented, this method can bypass some IDS.
Ninth trick: Comprehensive polymorphic coding
Smart, you will know when you read this subtitle. The so-called synthesis is to combine the several polymorphic coding techniques introduced above. In this way, the effect will be better. I hope this article will learn from you

[+] Structured Exception Handler (SEH) Exploitation notes
- Crash the application
- Check SEH overwirte (view-seh chain)
- Find offset (!mona pattern_create <length>)
- Find certain SEH references to the cyclic pattern (!mona findmsp)
- Verify offset to NSEH (Next Exception)
- Find POP/POP/RET address with mona (!mona seh -cpb <bad chars>)
- Add short jump into payload to jump ofver SEH ("\xeb\x06" + 2 bytes of padding)
- Add shellcode to the payload
- Ensure existing padding to make sure the crash still happens.
