iVentoy t\u00f6\u00f6riistakomplektis, mida kasutatakse arvutite v\u00f5rgust k\u00e4ivitamiseks ja installimiseks, leiti kahtlane tegevus. Windowsi ops\u00fcsteemi v\u00f5rgust k\u00e4ivitamise ajal pani t\u00f6\u00f6riist s\u00fcsteemi binaarse draiveri httpdisk.sys ja installis oma isesigned sertifikaadi, mida kasutati draiveri digitaalsete allkirjade kehtestamiseks, s\u00fcsteemsete juuresertifikaatide ladustamisse. 31 70-st viiruset\u00f5rje paketist, milles kontrolliti faili httpdisk.sys, andis hoiatuse pahavara olemasolu kohta. <\/p>\n

Sarnast tegevust t\u00f5lgendati kui potentsiaalset backdoor'i levitamise katset ja see t\u00f5statas usaldusv\u00e4\u00e4rsuse k\u00fcsimuse avatud projekti Ventoy suhtes. Situatsiooni halvendasid asjaolud, et eelmisel aastal p\u00e4rast XZ projekti backdoor'i intsidenti p\u00f6\u00f6ras kogukond juba t\u00e4helepanu Ventoy l\u00e4htekoodide puu kahtlaste blobide tarnimisele. <\/p>\n

NixOSi arendajad on ette pannud asendada Ventoy nixpkgs'i hoidlas fork'iga fnr1r (alternatiivina v\u00f5ib kaaluda ka glim'i). Ventoy ja iVentoy projekte arendab \u00fcks ja sama autor, ning neil on sarnane otstarve. Erinevused seisnevad selles, et Ventoy on t\u00e4ielikult avatud ja suunatud operatsioonis\u00fcsteemide k\u00e4ivitamisele USB-m\u00e4luseadmest, samas kui iVentoy on vaid osaliselt avatud ja m\u00f5eldud v\u00f5rgust k\u00e4ivitamiseks PXE-tehnoloogiat kasutades. <\/p>\n

Ventoy ja iVentoy projektide autor on probleemide arutamisega liitunud, selgitades, et httpdisk.sys draiveri kood on avatud ning see draiver on m\u00f5eldud Windowsis diskipiltide interneti kaudu montaa\u017eiks, kasutades HTTP-protokolli, mida iVentoy kasutab Windowsi installimisandmete saamiseks. serverile<\/a> Draiverite ja skriptide sisestamine s\u00fcsteemi p\u00e4rast k\u00e4ivitamist on dokumenteeritud k\u00e4itumine. <\/p>\n

Omandatud sertifikaat, millega see draiver allkirjastati, on lisatud juurkatalooge sertifikaatide s\u00e4ilitamiseks, et tagada draiveri laadimine Windowsi rakendatavast digitaalallkirjade kontrollis\u00fcsteemist m\u00f6\u00f6da. Sertifikaati kasutati ainult \u00fchekordses WinPE (Windowsi eelinstallatsiooni keskkond) keskkonnas, mis loodi operatiivm\u00e4lu kaudu. K\u00f5vakettale salvestatud Windowsi installatsioonides muudatusi ei tehtud. Teates on \u00f6eldud, et j\u00e4rgmises iVentoy v\u00e4ljaandes l\u00f5petatakse oma sertifikaadi asendamine, kuna draiveri laadimise tagamiseks kasutatakse WinPE k\u00e4ivitamist katsere\u017eimis. <\/p>\n

Seoses blobide (1, 2, 3) tarnimisega Ventoy's \u00fctles arendaja, et need binaarfailid on otse saadud teistest avatud projektidest ja Ventoy kasutab neid muutmata. Valmis teostatavad failid rakendatakse k\u00e4ivitatavate s\u00fcsteemide seadistamisel. Alternatiivina soovitatakse mitte kasutada valmis kogusid, vaid koostada need Ventoy versioonide jaoks iseseisvalt GitHub CI abil.
