En iyi yakanaka kwazvo posvo izvo zvabuda nhasi mu Tevera-Info, imwe yekupedzisira uye ine njodzi zvakanyanya panjodzi dzePDF inonzi, ichisimbisa zvatakasimudza yedu post nezuro. Ini ndinofambisira mberi hunhu hwenyaya: zvirinani shandisa iyo DJVU yemahara fomati; yakachengeteka zvakanyanya uye inogadzira madiki, emhando yepamusoro mafaera ... haingotsigirwe ne "hofori" seAdobe. |
Mazuva ano arikutenderera nenyika iro basa rakaitwa naDidier Stevens kuti mabinaries aurayiwe kubva pagwaro rePDF. Iyo nzira, kana iri kushandiswa Adobe Acrobat Reader, anoratidza meseji inogona kuve, sezvaanotaura iye, inoshandurwa zvishoma. In FoxItpane kudaro, hapana meseji inoratidzwa uye mirairo inoitwa pasina chero yambiro.
Iyi nzira yakapusa, yakatwasuka, uye nekudaro ine ngozi zvakanyanya, kana tikatarisa kuti iyo fomati yePDF ndiyo yaifarirwa nevashandisi gore rapfuura, ichisvika pakakwirira zvakanyanya zvekushandisa.
Ndichiona izvi, ndayeuka kuti muzvinyorwa zvakawanda paInternet, pavanotaura nezve maitiro ekushandisa kusagadzikana muPDF vanotaura zvinhu senge "Tsvaga vhezheni yeAcrobat yavari kushandisa, neFOCA, semuenzaniso" wobva wavaka kushandisa. Varombo FOCA vakanamatira mumazai iwayo ...
Chimwe chinhu chakafanana neicho yaive demo ratakagadzirira Zuva Rekuchengetedza, matakashandisa kushushikana muAcrobat Reader (kusanganisira vhezheni 9) kuti tiwane Shell iri kure pakombuta iri panjodzi. Kushushikana kuri kushandiswa kunofananidzirwa se CVE-2009-0927 uye mashandiro ayo anotendera kuita chero rairo. Kana iyo software iri panjodzi, iwe unowana meseji seiya inoonekwa mumufananidzo unotevera:
Uye iko kushandisa kwatinoshandisa kuendesa zvakare iyo Shell kune IP uye chiteshi kwatakaisa iyo netcat kuteerera.
Ehezve, mumuchina wakashandiswa, iyo Acrobat Reader maitiro ari kumhanya, achiteerera kumirairo yeShell.
Kuona njodzi yekushandisa kwePDF, ndakafunga kuiisa kuVirusTotal, kuti ndione mainjiniyenzi eantivirus anoita nezviitwa izvi mumapepa epdf. Izvo zvinonyanya kukosha kutora maitiro ayo kana tichitaura nezveinjini inoshandiswa mumaneja weemail kana mune gwaro repositi, sezvo iri munzvimbo idzodzo uko mamwe magwaro epdf anotama. Mhedzisiro iyi, pamwe nekushandisa kwakadai, kwanga kusiri kwakaipa, asi zvaishamisa kuti paive pachine huwandu hwakanaka hweinjini dzisina kuiona, asi iyo muzana haina kusvika 50% uye, mamwe acho, achirova saKaspersky, McAffe kana Fortinet.
Sechido chekuda kuziva, zvakaitika kwandiri kuti ndishandise faira kurongedza kugadzira zvinogoneka, zvakafanana newedu mudiwa redbinder yeThor, asi iine mashoma mashandiro anonzi Jiji uye pakanga paine yakaonekwa muCyberhades, kuti uone zvakaitwa nema antimalware enginisi patinoisa iyo pdf kushandisa mukati mehomwe nekuwedzera exe.
Iyi nyowani inogoneka, painomhanya, inotangisa gwaro neiyo pdf inoshandisa. Dzimwe nzira dzakayambuka pfungwa dzangu dzaive: A) vanoiburitsa uye vanhu kubva vasati vazviziva uye B) Vanoenda vakananga kuti vaone zviri mukati vobva vasaina mupaki.Zvisinei, mhedzisiro yacho yaishamisa.
Vaviri chete pane makumi mana nevaviri vakazviona, 2 semunhu aifungidzirwa, uye chete VirusBuster ndiyo yaiziva fomati, uye vakatora dambudziko, kuburitsa zvirimo kuti vatarise.
Mushure mekuona izvi, zvinoita seni chaizvo chaizvo kuti Microsoft neAdobe vari kufunga zvekuvandudza software kuburikidza neWindows Gadziriso uye kuti Microsoft yakavhura yayo Windows Kugadziridza Services chikuva kubatanidza dzimwe mhinduro dzakadai seWindows Gadziriso mumiriri. Secunia CSI, iyo inoshanda neSystem Center Configuration Manager uye WSUS.
Nditeerere zviri nani shandisa iyo DJVU yemahara fomati- yakachengeteka zvakanyanya uye inogadzira madiki, emhando yepamusoro mafaera.
