Angrebet p\u00e5 pakkeafh\u00e6ngigheder i NPM-repositorier er tr\u00e5dt ind i et nyt niveau. Ud over at bruge skadelig software til at opfange betalinger og fortrolige oplysninger er angriberne begyndt at implementere en orm i kompromitterede pakker for at automatisere inds\u00e6ttelse af skadelig software i afh\u00e6ngigheder. Brugen af ormen er blevet registreret efter kompromitteringen af NPM-pakken @ctrl\/tinycolor, som har 2,2 millioner ugentlige downloads og bruges som en direkte afh\u00e6ngighed i 964 pakker. Som f\u00f8lge af ormens aktivitet har angrebet omfattede 187 pakker, for hvilke der blev dannet skadelige udgivelser (477 skadelige versioner). <\/p>\n

Under det nye angreb, efter at angriberne har f\u00e5et adgang til en eskortkonto ved hj\u00e6lp af phishing, offentligg\u00f8r de en pakkeudgivelse med en orm, der aktiveres ved installation af den kompromitterede pakke blandt afh\u00e6ngighederne. Efter aktivering s\u00f8ger ormen efter legitimationsoplysninger i det nuv\u00e6rende milj\u00f8 ved at hente og k\u00f8re TruffleHog-v\u00e6rkt\u00f8jet. Hvis den opdager en NPM-forbindelsestoken, offentligg\u00f8r ormen automatisk en ny skadelig udgivelse og angriber afh\u00e6ngighedstr\u00e6et. Ud over adgangstokenet til NPM gemmer ormen ogs\u00e5 adgangsn\u00f8gler til GitHub og cloud-tjenester som AWS, Azure og GCP (Google Cloud Platform), samt andre fortrolige oplysninger, som TruffleHog-scanneren kan opdage. <\/p>\n

Skadelige udgivelser dannes for de 20 mest popul\u00e6re pakker, som den fundne NPM-token har adgang til. Funktionaliteten til at offentligg\u00f8re en udgivelse er implementeret i form af funktionen NpmModule.updatePackage, der henter den originale pakke-zipfil, \u00e6ndrer versionsnummeret og tilf\u00f8jer et postinstall-hook i package.json-filen, indl\u00e6gger en bundler.js-handler, ompakker pakken og offentligg\u00f8r den. Drift underst\u00f8ttes p\u00e5 Linux og macOS. <\/p>\n

Ormen fik kodeordet Shai-Hulud (en gigantisk orm n\u00e6vnt i romanen Dune). De fundne legitimationsoplysninger placeres p\u00e5 GitHub ved at oprette repositories med navnet Shai-Hulud (f.eks. \u00abB611\/Shai-Hulud\u00bb), og de afspejles ogs\u00e5 i kodet form i GitHub Actions-loggene. I det oprettede repository placeres en fil data.json, som indeholder en linje med base64-kodede oplysninger om systemet, milj\u00f8variabler og opsnappede adgangsn\u00f8gler. I CI baseret p\u00e5 GitHub opretter ormen en GitHub Actions-handler til at overf\u00f8re oplysninger til en ekstern v\u00e6rt (.github\/workflows\/shai-hulud-workflow.yml). Tilsyneladende er angrebet ikke begr\u00e6nset til de n\u00e6vnte 187 pakker, da der fortsat dukker nye repositories op p\u00e5 GitHub med navnet Shai-Hulud og filen data.json.

\"Selvudbredende<\/center> <\/p>\n

Blandt andet er 25 pakker fra CrowdStrike, der udvikler v\u00e6rkt\u00f8jer til beskyttelse imod angreb<\/a> via afh\u00e6ngigheder (Supply Chain) blevet ramt af ormens aktivitet. If\u00f8lge CrowdStrike blev de kompromitterede pakker ikke brugt p\u00e5 Falcon-platformen, og angrebet spredte sig ikke til kunderne. Det er ogs\u00e5 blevet kendt, at den forrige b\u00f8lge af offentligg\u00f8relse af ondsindede udgivelser p\u00e5 NPM, som fandt sted uden ormen, ber\u00f8rte projektet gemini-cli, der udvikles af Google.
