Microsofti turva-uuringud on v\u00e4lja t\u00f6\u00f6tanud Whisper Leaki k\u00f5rvalkanali r\u00fcnnaku tehnika, mis v\u00f5imaldab \u0161ifreeritud liiklust, mis edastatakse TLS-\u00fchenduse kaudu, passiivse anal\u00fc\u00fcsi alusel klassifitseerida k\u00fcsimuste teemasid suurte keelemudelite teenustes. Teave v\u00f5rgu paketide suuruste ja nende edastamise viivituste kohta oli piisav, et m\u00e4\u00e4rata AI-vestlusrobotitele esitatud p\u00e4ringute teemasid enam kui 98% t\u00e4psusega. Praktikas saab pakutud meetodit kasutada kasutaja transiitliikluses teatud p\u00e4ringute teemade tuvastamiseks, n\u00e4iteks teabe saamine ebaseaduslike tegevuste kohta, ilma sisu de\u0161ifreerimata. <\/p>\n

Andmete v\u00e4ljav\u00f5tmiseks, mudeli koolitamiseks ja meetodi testimiseks m\u00f5eldud t\u00f6\u00f6riistakomplekt on avaldatud GitHubis. R\u00fcnnaku v\u00f5imalust on demonstreeritud 28 populaarse suure keele mudeli kohta suurte tootjate poolt. N\u00e4iteks oli paljude AI-teenuste jaoks \u201eraha pesemise\u201d teemaliste p\u00e4ringute \u00f5igsus 100%, kui anal\u00fc\u00fcsitavas andmes g 1 n\u00f5utud p\u00e4ring ja 10000 p\u00e4ringut, mis ei olnud seotud vajaliku teemaga.

\"Whisper<\/center> <\/p>\n

Teabe lekkimise p\u00f5hjuseks on see, et mudelid genereerivad vastuse p\u00e4ringule samm-sammult, \u00fcks token korraga, kasutades igal sammul eelnevat tokenit kontekstina, et m\u00e4\u00e4rata j\u00e4rgmine k\u00f5ige t\u00f5en\u00e4olisem s\u00f5na v\u00f5i fraas. Seega saadetakse iga tokeni jaoks eraldi v\u00f5rgu pakett ja paketide vaheline viivitus vastab mudeli m\u00e4\u00e4ratud j\u00e4rgmise tokeni m\u00e4\u00e4ramise viivitusele. <\/p>\n

TLS-is, kui andmete tihendamist ei kasutata, vastab \u0161ifrit\u00fc\u00fcbi vahetus mitte\u0161ifreeritud teksti suurusele pluss konstant. Otsitavate tokenite kogumite ja paketide suuruste ning nende saatmise vaheline viivitus kokkuviimiseks mudeli loomisel on v\u00f5imalik \u00fcsna t\u00e4pselt m\u00e4\u00e4rata otsitavate teemade esinemine liikluses. Uuringu k\u00e4igus on loodud kolm sarnaste masin\u00f5ppe mudeli varianti, mis p\u00f5hinevad LightGBM, Bi-LSTM ja BERT n\u00e4rviv\u00f5rkude arhitektuuridel. Iga mudeli puhul on l\u00e4bi viidud katseid otsitava teema m\u00e4\u00e4ramiseks, anal\u00fc\u00fcsides ainult paketide suurusi, ainult paketide vahelisi viivitusi ja m\u00f5lemaid kriteeriume.

AI-teenuste arendajatele on soovitatud, et nad v\u00e4hendaksid passiivse p\u00e4ringuteema anal\u00fc\u00fcsi t\u00f5husust, kinnitades juhuslikke lisat\u00e4iendusi, puhvristades tokenite edastamist v\u00f5i asendades valepakette.
