(As it seems like no one did this before... I tried to )

One of the coolest things from OpenOffice (IMHO) is it's huge spell checking database, available for 92 languages. It contains not only the "most popular" words, but also some "mutation rules", which describe the generic "word formation" algorithm for each language. This opens great possibilities for a dictionary attack.

So, all I did was picking an "All Language Pack" from OpenOffice.org, and expanding it (i.e. using the affix rules to generate a list of all recognized words of a dictionary) with the unmunch utility from the Hunspell. As unmunch behaved a bit... weirdly with some .aff files (namely: ar, eu_ES, gl_ES, he_IL, hu_HU, lt_LT, mn_MN, qu_BO, se), I had to use the non-expanded .dic instead. This generated a set of lists with 127,153,335 unique words, which summed up into 1,932.2 MB.

And finally, here it is, for all your security testing purposes, packed with 7-Zip into a 167.3 MB file:

• The Pirate Bay (torrent)
• Mininova (torrent)

Theory

Recently, the world saw The Pirate Bay offering SSL encryption on their server. This means that your ISP won't know anymore which torrent you are downloading, right? Wrong.
HTTPS is quite useless for protecting static and public content. By static, I do mean the .torrent file itself. It is always the same. By public, I do mean than one doesn't need any kind of authentication to pick up the content. It's always the same, for everyone. For crawlers, too.
So, one could easily index (a portion of) The Pirate Bay torrent database by the Content-Length. Then, one could intercept some encrypted traffic between some machine(s) within his/her network and the torrents.thepiratebay.org server. Knowing both (encrypted) request and response lengths, it is possible to get a quite reliable list of matches from the previously indexed torrent list.

Practice

Don't try this at work, or you might hurt yourself

1. Use Wireshark to capture some torrent downloads. Torrents are hosted on a separate server, which makes the task easier yet. Just use the following capture filter: "tcp and port 443 and host torrents.thepiratebay.org"
2. Now, just go with the stream ("Follow TCP Stream" for the packet you suspect belongs to the torrent download. This will create another filter, just like "(ip.addr eq 192.168.0.10 and ip.addr eq 83.140.176.156) and (tcp.port eq 2157 and tcp.port eq 443)")
3. Just save the displayed stream anywhere else (pcap1.pcap sounds nice)
4. Now, use my quick&dirty TPB-TLSlen.pl Perl script to get the request/response lengths:

   perl TPB-TLSlen.pl pcap1.pcap

   Yeah, I know, it is nasty. It only supports the TLS cypher. And it simply calls the tshark (the command line version of Wireshark) to parse it's output.
5. Now, just paste the REQ and RES values below
   (note that the REQ value is optional, setting it to 0 simply ignores the request size for matching)

Precision

The following size distribution chart was generated using the database with ~165K torrents:

(binary torrent data)

Solution

1. Use a constant padding in the .torrent files. This messes things a bit, but stills ineffective. The only advantage is not messing up with the server
2. Patch the lighttpd server so it sends a non-lasting cookie with a random size.

Este projeto é o sucessor do CEP-2-City. É um formulário online que:

• Verifica a validade do número CPF
• Verifica a validade do número CNPJ
• A partir do CEP, deduz o endereço completo (Cidade/Estado/Bairro/Rua)
• A partir do CEP, deduz o código DDD da região

O banco de dados utilizado é compilado a partir de diversas fontes. Se não constar a informação da rua, então somente a cidade é retornada. A interface com o banco de dados foi implementada usando Perl e PHP, e pode ser acessada via CGI, Flash ou AJAX. O sistema de busca é extremamente eficiente, e não necessita de MySQL. O tamanho do banco de dados é cerca de 60 MB, e a performance chega a milhares de consultas por segundo.

Portanto, eis uma solução bastante símples, flexível e eficaz para o cadastro de clientes. Já utilizei este sistema numa pesquisa que conduzi, e asseguro que me poupou bastante tempo. Para realizar as consultas, basta acessar a seguinte URL (com a devida substituição do CEP): http://sysd.org/brloc/brloc.php?cep=05437000, e processar a string retornada com a função parse_str() (em PHP).

Se tiver interesse no banco de dados em si, entre em contato!

About Geolizer

This is an enhanced version of the popular Webalizer HTTP server statistics generator. It's main feature is an ability to discover visitor's country by his/her IP address. Default Webalizer method is to extract host suffix from the reversal DNS query (obtained directly from log files, or by webazolver program if HTTP server doesn't reverses client IPs), which is slow and imprecise (for example, Brazilian host could be reversed as .com). Geolizer relies on the GeoIP library API to do the same thing. Thus, no more DNS queries are required, and results are much more precise. Geolizer also has some additional features: it displays file sizes in a human-readable form (bytes/KB/MB/GB/TB) instead of default kilobytes. It also compiles under MinGW/MSYS now, so you can process your UN*X log files on your Windows box. And, finally, Geolizer features a nice eye-candy: country flags!

Beware as Geolizer also has some bad features (read "bugs"): for example, webazolver won't work anymore, and already resolved hosts aren't handled well. Want to see how it looks like, at all? Take a look at some sample statistics! Or see who else uses Geolizer to produce their server stats.

Tips

• The country flag pictures can be downloaded at http://flags.blogpotato.de/. Just download and unzip world.small.zip & special.small.zip to the flags/ subdirectory in your HTML output path.
• You may enhance your Webalizer further (allowing it to identify more user agents, referrers and search engines than normal) using extended configuration files, provided by Enric Naval and available at http://griho.udl.es/webalizer/.
• It is possible to use multiple configuration files on Webalizer. Just specify them at the command line:
  

  webalizer -c common.conf -c user_stas.conf
  

• Why don't you try also AWStats & WebDruid?!

Módulo Perl que obtém o nome do município (do Brasil) a partir de um CEP dado. Exemplo:

#!/usr/bin/perl
use CEP;

# inicializa
my $cep = new CEP;

# $city será referência para array com estado/cidade
my $city = $cep->city ('12.437-660'); # processa somente os dígitos numéricos (0-9)

if ($city) {
    # $str será uma string no formato Cidade/ESTADO
    my $str = CEP::city_string ($city);
    # filtra os acentos e imprime em caixa alta
    printf "esse CEP pertence a [%s]\n", uc CEP::normalize ($str);
} else {
    print "CEP não encontrado\n";
}

exit;

Conforme pode ser observado no exemplo dado acima, este é um módulo orientado a objeto. A instância do objeto CEP é criada com new CEP. Durante a inicialização, é construído um array com a lista ordenada das faixas de CEPs (isso pode demorar, portanto é uma boa idéia criar uma única instância e reaproveitá-la indefinidamente). O método que realiza a busca binária pelo CEP e retorna o nome do município é city(). O seu único parâmetro é o número CEP propriamente dito. Somente os dígitos numéricos serão considerados. city() retorna uma referência para array que contém o nome do estado e o nome da cidade, nessa ordem. Inclui também uma subrotina city_string() que recebe como parâmetro o array retornado pelo city() e retorna uma string no formato "Nome da cidade/ESTADO". E, finalmente, quando os acentos são desnecessários, pode-se filtrá-los com a função normalize(), que recebe uma string com acentos e a retorna sem acentos

P.S. - cuidado com os line-endings do arquivo CEP.pm! Se o segmento __DATA__ for salvo com CRLF, o módulo apresentará comportamento estranho em sistemas UN*X!
P.P.S. - Este projeto tem agora um sucessor (que consegue obter informação sobre Rua/Bairro e até mesmo DDD regional)! Confira!

Here I compiled the keyboard mapping for several versions of X-Plane. I wrote a tiny Perl program that simply formats the keys/X-Plane.txt file distributed with X-Plane into a comprehensible HTML table:

• X-Plane v6.70
• X-Plane v7.00
• X-Plane v7.41
• X-Plane v8.11

(for X-Plane v6.30, take a look here)

Designed to be the freakin' best ASCII table viewer for DOS platform, LOL!!!

It accesses the console font bitmaps directly from the BIOS and amplifies them 16 times (bitmaps in a hex form are shown, also). User can navigate the character map using his/her mouse or the cursor keys.  For every character, it's ASCII code in decimal, hexadecimal & binary formats is displayed. One can also build strings of ASCII characters, just like in Windows' "Character Map". Foreground/background colors for the character, magnified character & character string are also editable through the GUI (there are 16 colors available for background, instead of default 8 . It's pretty useless today, but helped me a lot to develop my elder programs. By the way, this ASCII explorer was written using QBasic 4.5...

This one looks like and feels like the popular "Microsoft ® Registry Editor" (A.K.A. regedit.exe ), specifically one that comes from Win2k default installation.
It only has one (significative) difference... It will never prompt you with following message box, when started:

"Registry editing has been disabled by your administrator."

REGEDIT4

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableRegistryTools"=dword:00000001

regedit.exe

P.S. - reg3dit has nothing to do with the leaked Win2k source!!! I've created it by my own.
