Judy Posted May 5, 2015 Report Share Posted May 5, 2015 Salutare!Una dintre probele unui concurs desfasurat anul trecut la politehnica a fost urmatoarea:Proba 13: HackerJohnAceasta cerin?? se afl? în fi?ierul de la adresa:http://swarm.cs.pub.ro/~mbunget/acadnet/Acadnet_proba13.zipPrimul concurent care rezolv? aceast? cerin?? prime?te punctajul de 10p, al 2-lea 9p ?i a?amai departe.Arhiva contine un fisier .txt si este protejata de o parola. Tinand cont ca timpul probei este de aproximativ 3 ore si nu exista nici un indiciu asupra numarului de caractere, o abordare de tip Bruteforce nu pare a fi rezolvarea ceruta.

goldman_us Posted June 14, 2015 Report Share Posted June 14, 2015 Din cate stiu era un prograram special care gasea acea parola, un fel de brute force Quote Link to comment Share on other sites More sharing options...
shobyone Posted June 16, 2015 Report Share Posted June 16, 2015 oricum a fost o proba buna p.s. parola nu are nici o legatura cu ce a postat aa7670 Quote Link to comment Share on other sites More sharing options...
bunnygod Posted August 25, 2015 Report Share Posted August 25, 2015 care e solutia? Quote Link to comment Share on other sites More sharing options...
Judy Posted April 26, 2016 Author Report Share Posted April 26, 2016 Stiu ca este un topic vechi, are aproape un an de acum, dar inca nu am reusit sa gasesc parola folosind bruteforce sau alta modalitate. Am incercat atat in Cloud cu bruteforce distribuit pe mai multe masini virtuale cu procesoare foarte puternice cat si pe sisteme cu placi video puternice, cu multe CUDA cores. Oricum, in timpul concursului ai la dispozitie un PC cu o configuratie mediocra, maxim i3 si 2GB RAM, deci cred ca alta este solutia problemei. Aveti vreo idee?

z0mbie Posted August 31, 2016 Report Share Posted August 31, 2016 Mai ai arhiva? Quote Link to comment Share on other sites More sharing options...
yo20063 Posted September 1, 2016 Report Share Posted September 1, 2016 Probabil numele probei "Proba 13: HackerJohn", este cel mai important indiciu. Parerea mea este ca parola arhivei este o parola sau derivarea unei parole gasite in dictionarul standard a programului John The Ripper, si de aceea stiind asta nu ai nevoie de foarte multa putere de calcul. Just my 2 cents! 1 Quote Link to comment Share on other sites More sharing options...
