Dezvoltatorii managerului de parole LastPass, care este utilizat de mai mult de 33 de milioane de persoane \u0219i peste 100 de mii de companii, au notificat utilizatorii cu privire la un incident prin care atacatorii au reu\u0219it s\u0103 ob\u021bin\u0103 acces la copiile de rezerv\u0103 ale stoc\u0103rii cu datele utilizatorilor serviciului. Datele includeau informa\u021bii precum numele de utilizator, adresa, emailul, telefonul \u0219i adresele IP de unde s-a realizat accesul la serviciu, precum \u0219i numele site-urilor nesecurizate salvate \u00een managerul de parole \u0219i log\u0103rile, parolele, datele formularelor \u0219i noti\u021bele asociate acestor site-uri salvate \u00eentr-o form\u0103 criptat\u0103. <\/p>\n

Pentru protejarea log\u0103rilor \u0219i parolelor c\u0103tre site-uri s-a folosit criptarea AES cu o cheie de 256 de bi\u021bi, generat\u0103 folosind func\u021bia PBKDF2 pe baza unei parole principale cunoscute doar de utilizator, av\u00e2nd o lungime minim\u0103 de 12 caractere. Criptarea \u0219i decriptarea log\u0103rilor \u0219i parolelor \u00een LastPass se efectueaz\u0103 doar pe partea utilizatorului, iar descoperirea parolei principale este considerat\u0103 nerealist\u0103 pe echipamentele moderne, av\u00e2nd \u00een vedere dimensiunea parolei principale \u0219i num\u0103rul de itera\u021bii aplicat \u00een PBKDF2. <\/p>\n

Pentru a efectua atacul, s-au folosit datele ob\u021binute de atacatori \u00een timpul unui atac anterior, care a avut loc \u00een august \u0219i a fost realizat prin compromiterea contului unuia dintre dezvoltatorii serviciului. Atacul din august a dus la accesarea de c\u0103tre infractori a mediului de dezvoltare, a codului aplica\u021biei \u0219i a informa\u021biilor tehnice. Ulterior, s-a constatat c\u0103 atacatorii au folosit datele din mediu pentru dezvoltare pentru a ataca un alt dezvoltator, reu\u0219ind s\u0103 ob\u021bin\u0103 cheile de acces la stocarea \u00een cloud \u0219i cheile necesare pentru decriptarea datelor din containerele stocate acolo. \u00cen cazul stoc\u0103rii compromise, servere<\/a> se aflau copii complete de rezerv\u0103 ale datelor serviciului activ.
