U alatu iVentoy, koji se koristi za pokretanje i instalaciju raznih operativnih sustava putem mre\u017ee, otkrivena je sumnjiva aktivnost. Prilikom mre\u017enog pokretanja sustava Windows, alat je izvr\u0161io zamjenu binarnih drajvera httpdisk.sys u sustavu i instalirao svoj samopotpisani certifikat u sistemsko spremi\u0161te korijenskih certifikata, koji se koristi za potpisivanje drajvera digitalnim potpisom. 31 od 70 antivirusnih paketa koji su provjeravali datoteku httpdisk.sys izdali su upozorenje o prisutnosti zlonamjernog softvera. <\/p>\n

Ova aktivnost percipirana je kao potencijalni poku\u0161aj uvo\u0111enja backdoora i otvorila je pitanje povjerenja u otvoreni projekt Ventoy. Situaciju je dodatno pogor\u0161alo to \u0161to je pro\u0161le godine, nakon incidenta s backdoorom u projektu XZ, zajednica ve\u0107 obra\u0107ala pa\u017enju na isporuku sumnjivih blobova u izvornoj strukturi projekta Ventoy. <\/p>\n

Razvija\u010di NixOS-a predlo\u017eili su zamjenu Ventoy-a u repozitoriju nixpkgs s fork-om fnr1r (kao alternativa se tako\u0111er mo\u017ee razmotriti glim). Projekti Ventoy i iVentoy razvijeni su od strane istog autora i imaju sli\u010dnu namjenu. Razlike su u tome \u0161to je Ventoy potpuno otvoren i namijenjen pokretanju operativnih sustava s USB ure\u0111aja, dok je iVentoy djelomi\u010dno otvoren i namijenjen za mre\u017eno pokretanje kori\u0161tenjem PXE tehnologije. <\/p>\n

U raspravu o problemu uklju\u010dio se autor projekata Ventoy i iVentoy, koji je pojasnio da je kod drajvera httpdisk.sys otvoren, a sam drajver je namijenjen montiranju diskovnih slika u Windows-u putem mre\u017ee preko HTTP protokola, \u0161to se koristi u iVentoy-u za dobivanje s poslu\u017eitelja<\/a> instalacijskih podataka Windows-a. Zamjena drajvera i skripti u sustavu nakon pokretanja je dokumentirano pona\u0161anje. <\/p>\n

Vlastiti certifikat, pomo\u0107u kojeg je potpisan ovaj upravlja\u010dki program, dodan je u spremi\u0161te korijenskih certifikata kako bi se omogu\u0107ilo u\u010ditavanje upravlja\u010dkog programa mimo primjenjivog sustava verifikacije programa putem digitalnog potpisa u Windowsu. Certifikat je bio kori\u0161ten samo u jednokratnom okru\u017eenju WinPE (Windows Preinstallation Environment), koje se stvara u radnoj memoriji. Nema promjena u standardnim instalacijama Windowsa na disku. Objava je da \u0107e se u sljede\u0107em izdanju iVentoy prestati koristiti vlastiti certifikat, jer \u0107e u\u010ditavanje upravlja\u010dkog programa biti omogu\u0107eno pokretanjem WinPE u testnom modu. <\/p>\n

\u0160to se ti\u010de isporuke blobova (1, 2, 3) u Ventoy, programer je izjavio da su ti binarni datoteke direktno preuzete iz drugih otvorenih projekata i Ventoy ih koristi bez izmjena. Gotove izvr\u0161ne datoteke se koriste u procesu postavljanja pokretnih sustava. Kao alternativna opcija sugerira se da se ne koriste gotove verzije, ve\u0107 da se sami sastave za izdanja Ventoy pomo\u0107u GitHub CI.
