GitHub har offentliggjort resultaterne af analysen af et angreb, hvor angrebere den 12. april fik adgang til de cloud-milj\u00f8er, der anvendes i Amazon AWS-tjenesten som en del af NPM-projektets infrastruktur. Analysen af h\u00e6ndelsen viste, at angriberne fik adgang til sikkerhedskopier af hosten skimdb.npmjs.com, herunder en sikkerhedskopi af databasen med oplysninger om cirka 100.000 NPM-brugere fra 2015, hvilket inkluderer hash af adgangskoder, navne og e-mail. <\/p>\n
Adgangskode-hashes blev oprettet ved hj\u00e6lp af PBKDF2-algoritmer eller SHA1 med salt, som i 2017 blev erstattet med den mere modstandsdygtige bcrypt. Efter opdagelsen af h\u00e6ndelsen blev de ber\u00f8rte adgangskoder nulstillet, og brugerne blev underrettet om behovet for at oprette en ny adgangskode. Da der fra den 1. marts er indf\u00f8rt obligatorisk tofaktorautentificering i NPM med e-mailbekr\u00e6ftelse, vurderes risikoen for brugerne at v\u00e6re minimal. <\/p>\n
Derudover kom angriberne i besiddelse af alle manifestfiler og metadata for private pakker pr. april 2021, CSV-filer med den aktuelle liste over alle navne og versioner af private pakker, samt indholdet af alle private pakker fra to GitHub-klienter (navne offentligg\u00f8res ikke). Hvad ang\u00e5r selve depotet, afsl\u00f8rede analysen af spor og verifikation af pakkens hashes ikke, at angriberne havde foretaget \u00e6ndringer i NPM-pakkerne eller offentliggjort falske nye versioner af pakker. <\/p>\n
Angrebet blev udf\u00f8rt den 12. april ved hj\u00e6lp af stj\u00e5lne OAuth-tokens, genereret til to tredjeparts GitHub-integratorer \u2014 Heroku og Travis-CI. Ved at udnytte disse tokens kunne angriberne hente en API-adgangsn\u00f8gle fra private GitHub-repositorier, der blev brugt i infrastrukturen til NPM-projektet. Den opn\u00e5ede n\u00f8gle gav adgang til data gemt p\u00e5 AWS S3-tjenesten. <\/p>\n
Derudover blev der afsl\u00f8ret oplysninger om tidligere identificerede alvorlige problemer med privatlivets fred ved behandling af brugerdata. servere<\/a> NPM \u2014 i de interne logfiler blev nogle brugeres adgangskoder samt adgangstokens til NPM gemt i klartekst. Under integrationen af NPM med GitHub's logningssystem sikrede udviklerne ikke, at fortrolige oplysninger blev fjernet fra loganmodningerne til NPM-tjenesterne. Det h\u00e6vdes, at fejlen blev rettet, og logfilerne blev renset f\u00f8r angrebet p\u00e5 NPM. Adgangen til logfilerne, der indeholdt \u00e5bne adgangskoder, var kun givet til udvalgte medarbejdere hos GitHub. \u041a\u043e\u043c\u043f\u0430\u043d\u0438\u044f GitHub
