Ce tare, redirect catre un executabil. Sa ma uit putin peste el, poate gasesc ceva interesant.

Întreb?ri de la cititorii ?i r?spunsuri de la autorii MalwareCity 1. De ce toat? lumea recomand? folosirea cript?rii de tip WPA sau WPA2, în locul celei WEP? Protocolul de criptare WEP (Wired Equivalent Privacy - „Confiden?ialitate echivalent? cu cea a unei conexiuni standard prin fir”) dateaz? din 1997. De-a lungul timpului, s-a demonstrat c? acest protocol are câteva erori de proiectare, care permit unui atacator s?-l sparg? în doar câteva minute. WPA ?i WPA2 (Wi-Fi Protected Access - „Acces Wi-Fi protejat”) sunt mult mai sigure decât protocolul WEP, care, de?i dep??it din punct de vedere tehnologic, este p?strat din cauza problemelor de compatibilitate cu echipamentele hardware mai vechi. În concluzie, dac? echipamentele dumneavoastr? suport? WPA sau WPA2, folosi?i-le pe acestea. De asemenea, v? sugerez s? arunca?i o privire ?i peste ghidul pe care l-am scris despre securizarea re?elelor wireless, pentru detalii suplimentare. 2. Cât de multe re?ele wireless pot exista într-o înc?pere ?i câte dintre ele pot fi securizate? Comunicarea wireless func?ioneaz? dup? acelea?i principii pe care le utilizeaz? ?i re?elele cu fir, cu singura excep?ie c? informa?ia circul? prin intermediul undelor radio în loc de fire de cupru. Astfel, pentru a comunica între ele, dispozitivele trebuie s? fac? parte dintr-o re?ea, pas ce este condi?ionat de nivelul de autentificare al re?elei. Ceea ce vede?i afi?at în gestionarul de conexiuni în re?ea este numele respectivei re?ele sau SSID-ul ei (Service Set IDentifier – „Identificatorul Setului de Serviciu”), care emite un semnal prin care avertizeaz? utilizatorii de existen?a unei re?ele la care se pot conecta. Totu?i, faptul c? vede?i re?eaua nu înseamn? neap?rat c? ve?i putea transmite ?i recep?iona date prin respectiva re?ea, decât dup? ce v-a?i conectat la ea. Celelalte re?ele wireless vor fi în continuare vizibile pentru calculator, cât? vreme se g?se?te în acela?i spa?iu fizic în care re?elele emit ?i calculatorul le poate „detecta”. Altfel spus, dac? sistemul dumneavoastr? nu se g?se?te în raza de ac?iune a celorlalte routere care emit semnal, el nu va putea s? „detecteze” celelalte re?ele. Ceea ce face ca informa?ia care circul? într-o re?ea s? r?mân? în interiorul acelei re?ele ?i s? nu fie interceptat? se nume?te criptare. De fapt, cheia de criptare este cea care nu v? permite s? intercepta?i traficul de date dintre doi clien?i legitimi (cum ar fi cel dintre router-ul ?i calculatorul vecinului dumneavoastr?). Chiar dac? pute?i s?-l intercepta?i fizic, el nu v? va spune nimic, fiindc? este protejat prin criptare de „privirile indiscrete”. 3. Cum pot s?-mi p?strez sistemul în siguran?? atunci când m? conectez la o re?ea wireless nesecurizat?? Dac? folosi?i o re?ea nesecurizat?, precum cea din c?min, bibliotec? sau dintr-o cafenea, v-a? recomanda s? evita?i pe cât posibil s? v? accesa?i conturile de e-mail, bancare etc. Un firewall bun v? ajut? s? restric?iona?i accesul la calculatorul dumneavoastr?, refuzând comunicarea pe anumite porturi considerate nesigure. Firewall-ul BitDefender are un mod Public, care nu numai c? v? filtreaz? comunicarea, dar v? ?i deconecteaz? resursele partajate în mod normal într-o re?ea, astfel încât s? nu v? expun? datele unui atacator conectat la aceea?i re?ea nesecurizat?. 4. Care este cea mai bun? modalitate de a ?ine al?i utilizatori la distan?? de propria mea re?ea wireless? Cel mai simplu mod este s? folosi?i criptarea WPA/WPA2 ?i s? v? securiza?i sec?iunea administrativ? a router-ului cu o parol? complex?. Ghidul de securitate pentru re?ele wireless pe care l-am publicat s?pt?mâna trecut? e un bun pas de pornire dac? inten?iona?i s? v? instala?i ?i s? configura?i propria re?ea sau dac? ave?i de gând s? spori?i gradul de securitate al celei existente. Cam atât pentru azi. Dac? dori?i s? primi?i un r?spuns la întreb?rile sau nel?muririle pe teme de securitate informatic?, nu ezita?i s?-mi scrie?i, folosind formularul de sub acest articol.

Interesant, mai ales ca eu sunt din Valcea. Cica "Hackerville" Si cei de acolo nu stiu sa faca o pagina de scam, puneau adresa de mail la care se duceau datele ca <input type="hidden" />, dadeau mancare la boschetari si le plateau orele la Internet Cafe ca sa stea sa Copy-Paste-uiasca manual adrese de mail, cei mai multi erau paraleli cu calculatoarele si se mai mira lumea cum de sunt prinsi... Chiar vorbeam cu cineva despre asta, cred ca foarte putini s-au gandit sa porneasca o afacere in loc sa ia un Audi, foarte putini s-au gandit sa spele banii... Dar na, si asta a contribuit la semnificatia mass-media a cuvantului "hacker", si cica suntem o tara de "hackeri", nu o tara de hoti, cand de fapt asta au fost si ei. Dar e bine, e loc pentru toata lumea la puscarie, acolo sa stea.

Hai sa discutam pe aceasta tema interesanta, sa dezbatem daca banul a fost meritat, sa clasificam limbajul victimei intr-unul adecvat sau unul potrivit coeficientului mediu de inteligenta de aici, sa aducem afirmatii pe care sa le sustinem cu dovezi concludente, stiti voi, ca in celelalte astfel de discutii de pe aici in care se implica numai persoane cu capabilitati intelectuale deosebite...

Iar ne-am adunat ca mustele la cacat. Felicitari.

Bun asa, mai scapam de ratati. Hai, aratati cat va duce capul.

As putea sa ii sterg posturile, dar face reclama negativa, bun baiat, ne arati cat de "smecher" e acel forum.

S-a inchis proiectul. S-au strans foarte putine articole. Poate se va redeschide ideea dupa ce termin cu sesiunea, cand voi termina un articol deja inceput si poate voi mai scrie unul.

Inca o "chestie" aniversara. Multumim pentru activitate, sper ca veti fi activi si pe viitor, dar sper sa va mai si maturizati si sa va ganditi si la lucruri mai serioase cum ar fi temele acestui forum. PS: Daca vreti un viitor in domeniul informaticii, ar trebui sa va ganditi mai profund la ce am spus mai sus, aici va puteti forma o baza solida, dar totul depinde de voi. La cat mai multe posturi (de o calitate mai ridicata)!

Cred ca Viz0n. La profil scrie ca e o fata de 15 ani dar nu prea cred. Oricum, nu asta conteaza, conteaza ca se ocupa de problemele site-ului. Au fost niste probleme cu inregistrarile, cu DNS-ul pentru IRC si altele si au fost remediate foarte repede. Se ocupa de site.

Tampenie veche si inutile. Topic inchis.

E un forum mai serios, cateva persoane care posteaza, le pasa de forum si de informatiile care se posteaza, nu prea am vazut aberatii sau intrebari stupide. Imi place, cel putin momentan. Stiu ca probabil ati auzit de el. http://r00tsecurity.org/forums/

Si pe ce criterii se vor alege utilizatorii? Zicem ca imi fac contul "x". Cont care nu il am si pe alte site-uri, deci nu vei putea stii cine sunt. Cine va fi ales, si cine nu? Se pot face neaprobari pentru useri ca "HackerCracker1337", dar cred ca numele de utilizator nu este de ajuns.

"Security Stuff" este o arie vasta. Pe langa un numar limitat de utilizatori care vor fi alesi de tine si de membrii alesi de tine, care ar fi noutatile? Va fi strict tehnic si nu se vor permite aberatiile?
