Udviklerne af Packj-platformen, der analyserer sikkerheden af biblioteker, har offentliggjort et \u00e5bent kommandolinjev\u00e6rkt\u00f8j, der muligg\u00f8r identifikation af risikable konstruktioner i pakker, som kan v\u00e6re relateret til gennemf\u00f8relsen af ondsindet aktivitet eller tilstedev\u00e6relsen af s\u00e5rbarheder, der bruges til at angibe projekter, der anvender de p\u00e5g\u00e6ldende pakker (e.g. 'supply chain'). Der underst\u00f8ttes kontrol af pakker p\u00e5 programmeringssprog som Python og JavaScript, der er hostet i PyPi og NPM (der planl\u00e6gges ogs\u00e5 st\u00f8tte til Ruby og RubyGems i denne m\u00e5ned). Koden til v\u00e6rkt\u00f8jet er skrevet i Python og distribueres under AGPLv3-licensen. <\/p>\n

Under analysen af 330.000 pakker ved hj\u00e6lp af det n\u00e6vnte v\u00e6rkt\u00f8j i PyPi-depotet blev der identificeret 42 skadelige pakker med bagd\u00f8re og 2.400 risikable pakker. Under unders\u00f8gelsen udf\u00f8res der en statisk kodeanalyse for at identificere API-funktioner og vurdere forekomsten af kendte s\u00e5rbarheder, der er registreret i OSV-databasen. MalOSS-pakken anvendes til API-analyse. Koden i pakkerne analyseres for tilstedev\u00e6relsen af typiske m\u00f8nstre, der almindeligvis anvendes i skadelig software. M\u00f8nstrene er baseret p\u00e5 en unders\u00f8gelse af 651 pakker med bekr\u00e6ftet skadelig aktivitet. <\/p>\n

Der identificeres ogs\u00e5 attributter og metadata, der \u00f8ger risikoen for utilsigtet brug, s\u00e5som udf\u00f8relse af blokke via 'eval' eller 'exec', generation af ny kode under k\u00f8rsel, brug af teknikker til forvirring og skjuling af kode (obfuscated), manipulation af milj\u00f8variabler, utilsigtet adgang til filer, adgang til netv\u00e6rksressourcer i installationsscripts (setup.py), brug af type-squatting (tildeling af navne svarende til popul\u00e6re biblioteker), identificering af for\u00e6ldede og forladte projekter, angivelse af ikke-eksisterende e-mail og hjemmesider samt frav\u00e6r af et offentligt repository med koden. <\/p>\n

Derudover kan det bem\u00e6rkes, at andre sikkerhedsunders\u00f8gere har identificeret fem skadelige pakker i PyPi-depotet, som sendte indholdet af milj\u00f8variabler med henblik p\u00e5 at stj\u00e6le tokens til AWS og systemer til kontinuerlig integration: loglib-modules (pr\u00e6senteret som moduler til det legitime bibliotek loglib), pyg-modules, pygrata og pygrata-utils (pr\u00e6senteret som tilf\u00f8jelser til det legitime bibliotek pyg) samt hkg-sol-utils. server<\/a> indhold af milj\u00f8variabler med henblik p\u00e5 at stj\u00e6le tokens til AWS og systemer til kontinuerlig integration: loglib-modules (pr\u00e6senteret som moduler til det legitime bibliotek loglib), pyg-modules, pygrata og pygrata-utils (pr\u00e6senteret som udvidelser til det legitime bibliotek pyg) samt hkg-sol-utils. <\/ul>\n
