El objetivo del proyecto es demostrar m\u00e9todos para ocultar su presencia despu\u00e9s de obtener acceso root y mantener la capacidad de realizar operaciones privilegiadas de forma oculta. Se espera que Singularity sea \u00fatil para investigadores de seguridad en la prueba y desarrollo de herramientas para detectar y bloquear rootkits.           <\/p>\n<p>El rootkit est\u00e1 dise\u00f1ado como un m\u00f3dulo para n\u00facleos de Linux 6.x y utiliza el mecanismo ftrace para interceptar llamadas al sistema de manera discreta, sin modificar los puntos de entrada de las llamadas al sistema y sin alterar las funciones del n\u00facleo. Singularity admite ocultar su presencia en el sistema, as\u00ed como ocultar los procesos que los atacantes designan y los archivos y actividades de red asociados. Para la comodidad de los investigadores, la funcionalidad del rootkit se divide en m\u00f3dulos.      <\/p>\n<p>Adem\u00e1s de los m\u00e9todos t\u00edpicos para ocultar la presencia en el sistema, como ocultar procesos, archivos, directorios y m\u00f3dulos del n\u00facleo necesarios, Singularity implementa varios m\u00e9todos avanzados para eludir mecanismos de protecci\u00f3n y dificultar la detecci\u00f3n por esc\u00e1neres de rootkits especializados, como Falco, ghostscan, tracee, unhide, chkrootkit y rkhunter. Entre otras cosas, Singularity puede ocultar su actividad de herramientas que utilizan eBPF, eliminar bloqueos de eBPF, prevenir la carga de m\u00f3dulos del n\u00facleo, resistir el an\u00e1lisis de entrada\/salida a trav\u00e9s del subsistema io_uring, as\u00ed como eludir verificaciones de integridad realizadas por el m\u00f3dulo LKRG (Linux Kernel Runtime Guard).       <\/p>\n<p>En Singularity hay un reverse shell que proporciona acceso remoto privilegiado al sistema mediante el env\u00edo de paquetes ICMP, as\u00ed como controladores que permiten ocultar procesos o elevar privilegios en el sistema a trav\u00e9s de ciertas manipulaciones de se\u00f1ales y variables de entorno. Por ejemplo, para ocultar un proceso de \/proc y de utilidades como ps, se puede ejecutar \"kill -59 PID_del_proceso\", y para elevar privilegios se debe establecer la variable de entorno \"MAGIC=mtz\".    <\/p>\n<p>El rootkit oculta el tr\u00e1fico reverse shell de los analizadores de red y permite evadir los manejadores de SELinux que se activan con ICMP. Singularity tambi\u00e9n incluye capacidades para ocultar ciertas conexiones de red de las tablas \/proc\/net\/nf_conntrack, manejadores netlink SOCK_DIAG\/NETFILTER y herramientas como netstat, ss, lsof, tcpdump y wireshark. Hay manejadores disponibles para limpiar mensajes de auditor\u00eda y registros (klogctl, syslog, systemd-journal, \/sys\/kernel\/debug\/tracing\/, dmesg). Existen filtros para contrarrestar analizadores de memoria como Volatility, que utilizan \/proc\/kcore, \/proc\/kallsyms y \/proc\/vmallocinfo, as\u00ed como capacidades de filtrado para evitar el acceso directo a dispositivos de bloques y prevenir el an\u00e1lisis a bajo nivel del contenido del sistema de archivos.      <center>  <div class=\"youtube-placeholder\" data-id=\"ByEp137w3Ks\"
