Reversing Pascal String Object

There are many goodware and malware developed in pascal, and we will see that the binary generated by the pascal compilers is fascinating, not only because the small and clean generated binaries, or the  clarity of the pascal code, but also the good performance. In Linux we have Lazarus which is a good free IDE like Delphi and Kylix the free pascal IDE for windows.

The program:

program strtest;

var
  cstr:  array[0..10] of char;
  s, s2:  ShortString;

begin
  cstr := 'hello world';
  s  := cstr;
  s2 := 'test';
  
  WriteLn(cstr + ' ' + s + ' ' + s2);
end.


We are going to compile it with freepascal and lazarus, and just the binary size differs a lot:

lazarus          242,176 btytes  845 functions
freepascal       32,256 bytes   233 functions
turbopascal      2,928 bytes     80 functions  (wow)

And surprisingly turbopascal binaries are extremely light.
Lets start with lazarus:

Logically it imports from user32.dll some display functions, it also import the kernel32.dll functions and suspiciously the string operations of oleaut32.dll 

And our starting point is a function called entry that calls the console initialization and retrieve some console configurations, and then start a labyrinth of function calls.

On functions 10000e8e0 there is the function that calls the main function.

I named execute_param2 because the second param is a function pointer that is gonna be executed without parameters, it sounds like main calling typical strategy.
And here we are, it's clearly the user code pascal main function.

What it seems is that function 100001800 returns an string object, then is called its constructor to initialize the string, then the string is passed to other functions that prints it to the screen.

This function executes the method 0x1c0 of the object until the byte 0x89 is a null byte.
What the hell is doing here?
First of all let's create the function main:

Simply right button create function:

After a bit of work on Ghidra here we have the main:

Note that the struct member so high like 0x1b0 are not created by default, we should import a .h file with an struct or class definition, and locate the constructor just on that position.

The mysterious function was printing byte a byte until null byte, the algorithm the compiler implemented in asm is not as optimized as turbopascal's.

In Windbg we can see the string object in eax after being created but before being initialized:












Just before executing the print function, the RCX parameter is the string object and it still identical:

Let's see the constructor code.
The constructor address can be guessed on static walking the reverse-cross-references to main, but I located it in debugging it in dynamic analysis.

The constructor reads only a pointer stored on the string object on the position 0x98.

And we have that the pointer at 0x98 is compared with the address of the literal, so now we know that this pointer points to the string.
The sentence *string_x98 = literal confirms it, and there is not memory copy, it only points reusing the literal.

Freepascal

The starting labyrinth is bigger than Lazarus so I had to begin the maze from the end, searching the string "hello world" and then finding the string references:

There are two ways to follow the references in Ghidra, one is [ctrl] + [shift] + F  but there is other trick which is simply clicking the green references texts on the disassembly.

At the beginning I doubted and put the name possible_main, but it's clearly the pascal user code main function.

The char array initialization Is converted by freepascal compiler to an runtime initialization using mov instructions.

Reducing the coverage on dynamic we arrive to the writeln function:

EAX helds  a pointer to a struct, and the member 0x24 performs the printing. In this cases the function can be tracked easily in dynamic executing the sample.

And lands at 0x004059b0 where we see the WriteFile, the stdout descriptor, the text and the size supplied by parameter.

there is an interesting logic of what happens if WriteFile() couldn't write all the bytes, but this is other scope.
Lets see how this functions is called  and how text and size are supplied to figure out the string object.

EBX helds the string object and there are two pointers, a pointer to the string on 0x18 and the length in 0x18, lets verify it on windbg.

And here we have the string object, 0x0000001e is the length, and 0x001de8a68 is the pointer.

Thanks @capi_x for the pascal samples.

Collection Of Pcap Files From Malware Analysis

Update: Feb 19. 2015

We have been adding pcaps to the collection so remember to check out the folder ( Pcap collection) for the recent pcaps.

I had a project to test some malicious and exploit pcaps and collected a lot of them (almost 1000) from various public sources. You can see them in the PUBLIC folder. The credits go to the authors of the pcaps listed in the name of each file. Please visit their blogs and sites to see more information about the pcaps, see their recent posts, and send them thanks. The public pcaps have no passwords on them.




Update:Dec 13. 2014 

Despite rare updates of this post, we have been adding pcaps to the collection so remember to check out the folder ( Pcap collection (New link)) for the recent pcaps!

Update:Dec 31. 2013 - added new pcaps

I did some spring cleaning yesterday and came up with these malware and exploit pcaps. Such pcaps are very useful for IDS and signature testing and development, general education, and malware identification. While there are some online public sandboxes offering pcaps for download like Cuckoo or Anubis but  looking for them is a tedious task and you cannot be totally sure the pcap is for the malware family supposedly analysed - in other words, if the sandbox says it is Zeus does not necessarily mean that it is.

I found some good pcap repositories here (http://www.netresec.com/?page=PcapFiles) but there are very few pcaps from malware.

These are from identified and verified (to the best of my knowledge and belief - email me if you find errors) malware samples.

All of them show the first stage with the initial callback and most have the DNS requests as well. A few pcaps show extended malware runs (e.g. purplehaze pcap is over 500mb).
Most pcaps are mine, a few are from online sandboxes, and one is borrowed from malware.dontneedcoffee.com. That said, I can probably find the corresponding samples for all that have MD5 listed if you really need them. Search contagio, some are posted with the samples.

Each file has the following naming convention:
BIN [RTF, PDF] - the filetype of the dropper used, malware family name, MD5, and year+month of the malware analysis.

I will be adding more pcaps in the future. Please donate your pcaps from identified samples, I am sure many of you have.

Thank you

Download

Download all together or separately.

All pcaps archives have the same password (same scheme), email me if you need it. I tried posting it without any passwords and pass infected but they get flagged as malware. Modern AV rips though zips and zips with the pass 'infected' with ease.

Top 10 Most Popular Ethical Hacking Tools (2019 Ranking)

     Top 10 powerful Hacking  Tools in 2019.       

If hacking is performed to identify the potential threats to a computer or network then it will be an ethical hacking.

Ethical hacking is also called penetration testing, intrusion testing, and red teaming.

Hacking is the process of gaining access to a computer system with the intention of fraud, data stealing, and privacy invasion etc., by identifying its weaknesses.

Ethical Hackers:

A person who performs the hacking activities is called a hacker.

There are six types of hackers:

• The Ethical Hacker (White hat)
• Cracker
• Grey hat
• Script kiddies
• Hacktivist
• Phreaker

A security professional who uses his/her hacking skills for defensive purposes is called an ethical hacker. To strengthen the security, ethical hackers use their skills to find vulnerabilities, document them, and suggest the ways to rectify them.

Companies that provide online services or those which are connected to the internet, must perform penetration testing by ethical hackers. Penetration testing is another name of ethical hacking. It can be performed manually or through an automation tool.

Ethical hackers work as an information security expert. They try to break the security of a computer system, network, or applications. They identify the weak points and based on that, they give advice or suggestions to strengthen the security.

Programming languages that are used for hacking include PHP, SQL, Python, Ruby, Bash, Perl, C, C++, Java, VBScript, Visual Basic, C Sharp, JavaScript, and HTML.

Few Hacking Certifications include:

1. CEH
2. GIAC
3. OSCP
4. CREST

Resolución De ExpedientesX De Código

Hoy me he topado con algo bastante gracioso que puede liarte unos minutos:

python
>>> import re
>>> a='owjf oasijf aw0oifj osfij 4.4.4.4 oasidjfowefij 192.168.1.1'


ok, pues ahora copy-pasteais cada una de estas:
re.findall('[0-9]̣̣',a)
re.findall('[0-9]',a)

Son exactamente iguales, pero si paseteais una da resultados diferente a si pasteais la otra :)

Pasteamos la primera:
>>> re.findall('[0-9]̣̣',a)
[]

Pasteamos la segunda:
>>> re.findall('[0-9]',a)
['0', '4', '4', '4', '4', '1', '9', '2', '1', '6', '8', '1', '1']


o_O, he repasado caracter a caracter y son visualmente iguales, si mirais en un editor hexa vereis que realmente no lo son, lógicamente no se trata de un expedienteX.

La cuestion es que según la fuente que tengais, debajo de la comilla o debajo del ] hay un punto microscópico :)

Esto es como cuando me emparanoie de que gmail cuando llevas un rato escribiendo un email y se hace auto-save, aparece una especie de acento raro en la pantalla :)

En estos casos, la metodología tipica de copypastear un trozo de la primera sentencia con el resto de la segunda sentencia, te lleva a los 2 caracteres que varían, pero no aprecias (segun la fuente que tengas) la diferéncia.

6572 662e 6e69 6164 6c6c 2728 305b 392d 275d 612c 0a29

Son dígitos unicode, sabe Dios de que pais, y sabe Dios también como los escribí con mi teclado,
se me ocurren bromas de código fuente que se pueden hacer con esto :D, pero vamos, si tenemos metodología de reaccién ante expedientesX, sobretodo aquello de divide y vencerás dicotómico, en pocos minutos se resuelven este tipo de problemas.
