Udviklerne af password manageren LastPass, som bruges af mere end 33 millioner mennesker og over 100.000 virksomheder, har informeret brugerne om en h\u00e6ndelse, hvor angribere fik adgang til backupkopier af opbevaringen af brugerdata. Dataene omfattede oplysninger som brugernavn, adresse, e-mail, telefonnummer og IP-adresser, hvorfra der blev logget ind p\u00e5 tjenesten, samt de ikke-krypterede webstedsnavne, der blev gemt i password manageren, og de krypterede loginoplysninger, adgangskoder, formularoplysninger og noter til disse websteder. <\/p>\n

Til beskyttelse af login og adgangskoder til websteder blev der anvendt AES-kryptering med en 256-bit n\u00f8gle, der blev genereret ved hj\u00e6lp af PBKDF2-funktionen baseret p\u00e5 den kun kendte masteradgangskode, som skal v\u00e6re mindst 12 tegn lang. Krypteringen og dekrypteringen af loginoplysninger og adgangskoder i LastPass udf\u00f8res kun p\u00e5 brugerens side, og g\u00e6tningen af masteradgangskoden betragtes som urealistisk p\u00e5 moderne hardware, givet st\u00f8rrelsen p\u00e5 masteradgangskoden og det anvendte antal PBKDF2-iterationer. <\/p>\n

Til angrebet blev der brugt data, som angriberne havde f\u00e5et fat i under et tidligere angreb, der fandt sted i august og blev udf\u00f8rt gennem kompromittering af en af udviklernes konti. August-angrebet medf\u00f8rte, at angriberne fik adgang til udviklingsmilj\u00f8et, applikationskoden og teknisk information. Senere blev det klart, at angriberne udnyttede oplysningerne fra udviklingsmilj\u00f8et til at angribe en anden udvikler, hvilket resulterede i, at de fik adgang til n\u00f8glerne til cloud-lagringen og n\u00f8glerne til dekryptering af dataene fra de opbevarede containere. P\u00e5 de kompromitterede cloud-l\u00f8sninger servere<\/a> blev der opbevaret komplette backupkopier af dataene fra den fungerende tjeneste.
