Tvrtka Intel je potvrdila autenti\u010dnost izvornog koda UEFI firmware-a i BIOS-a objavljenih od strane nepoznatog korisnika na GitHub-u. Ukupno je objavljeno 5.8 GB koda, alata, dokumentacije, blobova i postavki povezanih s razvojem firmware-a za sustave s procesorima temeljenim na mikroarhitekturi Alder Lake, koja je pu\u0161tena u studenom 2021. godine. Najnovija izmjena u objavljenom kodu datira iz 30. rujna 2022. godine. <\/p>\n
Prema izjavi Intela, curenje se dogodilo zbog tre\u0107e strane, a ne uslijed kompromitacije infrastrukture tvrtke. Tako\u0111er se spominje da objavljeni kod obuhva\u0107a program Project Circuit Breaker, koji podrazumijeva isplatu nagrada u iznosu od 500 do 100000 dolara za otkrivanje sigurnosnih problema u firmware-u i Intelovim proizvodima (podrazumijeva se da istra\u017eiva\u010di mogu dobiti nagradu za prijave ranjivosti otkrivenih kori\u0161tenjem sadr\u017eaja curenja). <\/p>\n
Nije navedeno ko je ta\u010dno postao izvor curenja (pristup alatu za kreiranje firmvera imali su OEM proizvo\u0111a\u010di opreme i kompanije koje razvijaju firmware po narud\u017ebi). Tokom analize sadr\u017eaja objavljenog arhiva otkriveni su neki specifi\u010dni testovi i servisi proizvoda kompanije Lenovo (\"Lenovo Feature Tag Test Information\", \"Lenovo String Service\", \"Lenovo Secure Suite\", \"Lenovo Cloud Service\"), ali povezanost kompanije Lenovo sa curenjem jo\u0161 nije potvr\u0111ena. U arhivu su tako\u0111e otkriveni alati i biblioteke kompanije Insyde Software, koja se bavi razvojem firmvera po narud\u017ebi OEM proizvo\u0111a\u010da, a u git log-u prisutan je email jednog od zaposlenih kompanije LC Future Center, koja proizvodi laptopove za razli\u010dite OEM proizvo\u0111a\u010de. Obe kompanije sara\u0111uju sa Lenovom. <\/p>\n
Prema mi\u0161ljenju kompanije Intel, kod koji je postao javno dostupan ne sadr\u017ei povjerljive podatke ili komponente koje bi mogle doprineti otkrivanju novih ranjivosti. U me\u0111uvremenu, Mark Ermolov, specijalizovan za istra\u017eivanje sigurnosti Intelovih platformi, otkrio je u objavljenom arhivu informacije o nedokumentovanim MSR registrima (Model Specific Registers, kori\u0161\u0107eni i za upravljanje mikrokodom, pra\u0107enje i debagovanje), \u010dije informacije podle\u017eu sporazumu o neotkrivanju. \u0160tavi\u0161e, u arhivu je prona\u0111en tajni klju\u010d koji se koristi za digitalno potpisivanje firmvera, koji se potencijalno mo\u017ee iskoristiti za zaobila\u017eenje za\u0161tite Intel Boot Guard (funkcionalnost klju\u010da nije potvr\u0111ena, mogu\u0107e je da je to testni klju\u010d). \u041a\u043e\u043c\u043f\u0430\u043d\u0438\u044f Intel \u043f\u043e\u0434\u0442\u0432\u0435\u0440\u0434\u0438\u043b\u0430
