Toetatakse pakettide kontrollimist Python ja JavaScripti keeles, mis on paigutatud PyPi ja NPM kataloogidesse (k\u00e4esoleval kuul plaanitakse lisada ka Ruby ja RubyGems. T\u00f6\u00f6riista kood on kirjutatud Pythonis ja see on levitatud AGPLv3 litsentsi alusel. <\/p>\n

Anal\u00fc\u00fcsi k\u00e4igus, mille raames uuriti 330 000 paketti PyPi hoidlas, tuvastati 42 pahatahtlikku paketti, millel on tagaukse funktsionaalsus, ja 2400 riskantset paketti. Uurimise protsessis viiakse l\u00e4bi staatiline koodi anal\u00fc\u00fcs, et tuvastada API-erinevusi ja hinnata tuntud haavatavuste olemasolu, mis on m\u00e4rgitud OSV andmebaasis. API anal\u00fc\u00fcsimiseks kasutatakse MalOSS paketti. Pakettide koodi anal\u00fc\u00fcsitakse pahatahtliku tarkvara puhul tavaliselt kasutatavate mustrite tuvastamiseks. Mustrid on koostatud 651 kinnitatud pahatahtliku tegevuse paketist. <\/p>\n

Samuti tuvastatakse atribuudid ja metaandmed, mis suurendavad sihilikult kasutamise riski, nagu plokkide k\u00e4itamine «eval» v\u00f5i «exec» kaudu, uue koodi genereerimine jooksu ajal, koodipeitmise ja keerukuse meetodite (obfuscated) kasutamine, keskkonnamuutujate manipuleerimine, sihilik juurdep\u00e4\u00e4s failidele, ligip\u00e4\u00e4s v\u00f5rguresurssidele seadistusskriptides (setup.py), nimede m\u00e4\u00e4ramine, mis sarnanevad tuntud raamatukogude nimedega, aegunud ja mahaj\u00e4etud projektide tuvastamine, mitteeksisteerivate e-posti aadresside ja veebisaitide n\u00e4itamine, ning puuduv avalik koodirepositoorium. <\/p>\n
