Los desarrolladores del lenguaje Rust han advertido sobre la detecci\u00f3n en el repositorio crates.io de un paquete rustdecimal que contiene c\u00f3digo malicioso. El paquete se bas\u00f3 en un paquete leg\u00edtimo llamado rust_decimal y aprovech\u00f3 la similitud en el nombre (typosquatting), confiando en que el usuario no notar\u00eda la falta de un guion bajo al buscar o seleccionar el m\u00f3dulo de la lista. <\/p>\n
Es notable que la estrategia mencionada tuvo \u00e9xito y, en t\u00e9rminos de descargas, el paquete falso se qued\u00f3 muy cerca del original (~111 mil descargas de rustdecimal 1.23.1 y 113 mil del original rust_decimal 1.23.1). La mayor\u00eda de las descargas fueron para el clon inofensivo que no conten\u00eda c\u00f3digo malicioso. Las modificaciones maliciosas se a\u00f1adieron el 25 de marzo en la versi\u00f3n rustdecimal 1.23.5, que, antes de que se detectara el problema y se bloqueara el paquete, se descarg\u00f3 unas 500 veces (se supone que la mayor parte de las descargas de la versi\u00f3n maliciosa fueron realizadas por bots) y no fue utilizada como dependencia en otros paquetes presentes en el repositorio (no se descarta que el paquete malicioso estuviera en las dependencias de aplicaciones finales). <\/p>\n
Los cambios maliciosos consist\u00edan en la adici\u00f3n de una nueva funci\u00f3n Decimal::new, cuya implementaci\u00f3n conten\u00eda c\u00f3digo ofuscado para cargar desde un externo servidores<\/a> y ejecutar un archivo ejecutable. Al invocar la funci\u00f3n, se verificaba la variable de entorno GITLAB_CI, y si se activaba, se cargaba un archivo desde el servidor externo \/tmp\/git-updater.bin. El manejador malicioso soportaba su funcionamiento en Linux y macOS (la plataforma Windows no era compatible). <\/p>\n Se supon\u00eda que la funci\u00f3n maliciosa se ejecutar\u00eda durante las pruebas en sistemas de integraci\u00f3n continua. Despu\u00e9s de bloquear rustdecimal, los administradores de crates.io analizaron el contenido del repositorio en busca de inserciones maliciosas similares, pero no encontraron problemas en otros paquetes. Se recomienda a los propietarios de sistemas de integraci\u00f3n continua basados en la plataforma GitLab que se aseguren de que sus como en entornos de nube p\u00fablicos o privados.<\/a> proyectos no hayan utilizado el paquete rustdecimal en sus dependencias. \u0420\u0430\u0437\u0440\u0430\u0431\u043e\u0442\u0447\u0438\u043a\u0438 \u044f\u0437\u044b\u043a\u0430 Rust
