\u00cen octombrie 2017, a devenit evident c\u0103 protocolul Wi-Fi Protected Access II (WPA2) pentru criptarea traficului Wi-Fi are o vulnerabilitate grav\u0103, care permite identificarea parolelor utilizatorilor \u0219i apoi interceptarea comunic\u0103rii victimei. Vulnerabilitatea a fost denumit\u0103 KRACK (abreviere pentru Key Reinstallation Attack) \u0219i a fost descoperit\u0103 de speciali\u0219tii Mathy Vanhoef \u0219i Eyal Ronen. Dup\u0103 descoperirea vulnerabilit\u0103\u021bii, KRACK a fost remediat\u0103 prin actualiz\u0103ri de firmware pentru dispozitive, iar noul protocol WPA3, care a \u00eenlocuit WPA2 anul trecut, ar fi trebuit s\u0103 elimine problemele de securitate \u00een re\u021belele Wi-Fi. <\/p>\n

\"Dragonblood:<\/p>\n

Din p\u0103cate, aceia\u0219i speciali\u0219ti au descoperit vulnerabilit\u0103\u021bi chiar mai periculoase \u00een protocolul WPA3. Astfel, trebuie s\u0103 a\u0219tept\u0103m din nou \u0219i s\u0103 sper\u0103m \u00een actualiz\u0103ri de firmware pentru punctele de acces wireless \u0219i dispozitive, altfel va trebui s\u0103 tr\u0103im cu cuno\u0219tin\u021ba despre vulnerabilit\u0103\u021bile re\u021belelor Wi-Fi de acas\u0103 \u0219i publice. Vulnerabilit\u0103\u021bile identificate \u00een WPA3 au primit denumirea comun\u0103 de Dragonblood.<\/p>\n

R\u0103d\u0103cinile problemei, ca \u00eentotdeauna, se afl\u0103 \u00een func\u021bionarea mecanismului de stabilire a conexiunii, sau, cum sunt denumite \u00een standard, \u201eap\u0103sarea m\u00e2inii\u201d. Acest mecanism \u00een standardul WPA3 se nume\u0219te Dragonfly (libelul\u0103). P\u00e2n\u0103 la descoperirea Dragonblood, era considerat bine protejat. \u00cen pachetul Dragonblood au fost incluse cinci tipuri de vulnerabilit\u0103\u021bi: atacuri de refuz de serviciu, dou\u0103 vulnerabilit\u0103\u021bi de degradare a securit\u0103\u021bii re\u021belei \u0219i dou\u0103 vulnerabilit\u0103\u021bi de atac prin canale laterale.<\/p>\n

\n\"Dragonblood:<\/p>\n

Atacurile de refuz de serviciu nu conduc la scurgerea de date, dar pot reprezenta un eveniment nepl\u0103cut pentru utilizatorul care nu poate s\u0103 se conecteze de mai multe ori la punctul de acces. Celelalte vulnerabilit\u0103\u021bi permit atacatorului s\u0103 recupereze parolele pentru conectarea utilizatorului la punctul de acces \u0219i s\u0103 urm\u0103reasc\u0103 orice informa\u021bie critic\u0103 pentru utilizator.<\/p>\n

Atacurile care degradeaz\u0103 securitatea re\u021belei permit for\u021barea trecerii la o versiune mai veche a protocolului WPA2 sau la variante mai slabe ale algoritmilor de criptare WPA3, permi\u021b\u00e2nd apoi continuarea atacului cu metode deja cunoscute. Atacurile prin canale laterale exploateaz\u0103 caracteristicile algoritmilor WPA3 \u0219i implementarea lor, ceea ce \u00een cele din urm\u0103 permite utilizarea metodelor de spargere a parolilor deja cunoscute. Detalii suplimentare aici. Un set de instrumente pentru identificarea vulnerabilit\u0103\u021bilor Dragonblood poate fi g\u0103sit la acest link.<\/p>\n

\"Dragonblood:<\/p>\n

Alian\u021ba Wi-Fi, responsabil\u0103 pentru dezvoltarea standardelor Wi-Fi, a fost informat\u0103 despre vulnerabilit\u0103\u021bile descoperite. Se raporteaz\u0103 c\u0103 produc\u0103torii de echipamente preg\u0103tesc firmware-uri modificate pentru a \u00eenchide bre\u0219ele de securitate identificate. Nu va fi nevoie de \u00eenlocuiri sau return\u0103ri de echipamente.<\/p>\n
