Recientemente, los \u00abdroppers\u00bb fueron el principal objetivo de la gran operaci\u00f3n policial de Europol contra programas maliciosos, \u00bfpero qu\u00e9 son?<\/a><\/a><\/a><\/a><\/p>\n\n\n\n

Piedra angular de numerosas ciberataques<\/a>, los \u00abdroppers\u00bb<\/strong> fueron el principal objetivo de la gran operaci\u00f3n policial de Europol contra programas maliciosos anunciada este jueves, que provoc\u00f3 numerosas detenciones y la desconexi\u00f3n de un centenar de servidores.<\/p>\n\n\n\n

Estos programas, poco conocidos por el gran p\u00fablico, facilitan los\u00a0ciberataques<\/strong>\u00a0a empresas, autoridades e instituciones nacionales, ocasionando da\u00f1os por cientos de millones de euros. Pero, \u00bfen qu\u00e9 consisten?<\/p>\n\n\n\n

\u00bfQu\u00e9 es un \u00abdropper\u00bb?<\/h2>\n\n\n\n

Un \u00abdropper\u00bb es un software<\/strong> cuya funci\u00f3n principal es \u00ababrir la puerta a otros programas maliciosos\u00bb, explica a AFP J\u00e9r\u00f4me Saiz, experto en ciberseguridad y fundador de la empresa OPFOR Intelligence.<\/p>\n\n\n\n

\u00abNo es \u00e9l quien realiza la acci\u00f3n maliciosa\u00bb, precisa.<\/p>\n\n\n\n

Peque\u00f1o, ligero, dise\u00f1ado para pasar desapercibido<\/strong> y enga\u00f1ar a los antivirus, este software puede llegar al ordenador de un usuario que hace clic en una publicidad maliciosa, navega sin darse cuenta por un sitio malicioso o descarga una aplicaci\u00f3n leg\u00edtima que lo esconde.<\/p>\n\n\n\n

Los \u00abdroppers\u00bb tambi\u00e9n pueden ser depositados en un ordenador a trav\u00e9s de correos electr\u00f3nicos<\/a> con enlaces infectados o archivos adjuntos<\/strong> de Word y PDF, indica la agencia judicial europea Eurojust.<\/p>\n\n\n\n

\u00abEs en el momento de la\u00a0instalaci\u00f3n del software<\/strong>\u00a0cuando se desencadena la carga viral\u00bb y se \u00ababre la mu\u00f1eca rusa\u00bb, detalla Jean-Fran\u00e7ois Beuze, presidente de la empresa de ciberseguridad Sifaris.<\/p>\n\n\n\n

\u00bfC\u00f3mo funciona?<\/h2>\n\n\n\n

Una vez instalado, el \u00abdropper abre el campo de posibilidades a los piratas\u00bb, subraya J\u00e9r\u00f4me Saiz.<\/p>\n\n\n\n

Puede ser aut\u00f3nomo<\/strong>, con sus propios programas maliciosos incorporados, o puede buscar programas maliciosos en internet, facilitar su instalaci\u00f3n y activaci\u00f3n.<\/p>\n\n\n\n

Puede tratarse de un \u00abransomware\u00bb o programa chantajeador, que explota vulnerabilidades<\/strong> de seguridad de una empresa o individuo para cifrar y bloquear sus sistemas inform\u00e1ticos, exigiendo un rescate para desbloquearlos.<\/p>\n\n\n\n

Pero algunos \u00abdroppers\u00bb son capaces incluso de utilizar el ordenador infectado para \u00abminar\u00bb bitcoins, es decir,\u00a0validar transacciones\u00a0<\/strong>en criptomoneda, sin que el propietario lo sepa. O descifrar contrase\u00f1as.<\/p>\n\n\n\n

En el caso de la operaci\u00f3n de Europol, los \u00abdroppers\u00bb desactivados estaban asociados a al menos 15\u00a0grupos de ransomware<\/strong>, algunos de los cuales se han utilizado para extorsionar a hospitales y centros de salud en Estados Unidos durante la pandemia de covid-19.<\/p>\n\n\n\n

\u00abLos atacantes hacen esto porque les permite, con un solo y peque\u00f1o software, instalar de manera muy modular y granular lo que quieren\u00bb, contin\u00faa.<\/p>\n\n\n\n

Cumplida su misi\u00f3n, el \u00abdropper\u00bb puede \u00abeliminarse totalmente de tu ordenador\u00bb, se\u00f1ala Jean-Fran\u00e7ois Beuze.<\/p>\n\n\n\n

\u00bfC\u00f3mo protegerse?<\/h2>\n\n\n\n

Las grandes empresas<\/a>\u00a0tienen\u00a0sistemas de detecci\u00f3n<\/strong>\u00a0de actividades maliciosas bastante avanzados, especialmente con inteligencia artificial, que les permiten protegerse contra los \u00abdroppers\u00bb. Pero es mucho m\u00e1s complicado para las peque\u00f1as empresas, se\u00f1ala Beuze.<\/p>\n\n\n\n

Ambos expertos celebran as\u00ed la operaci\u00f3n de Europol <\/strong>que ha permitido desestabilizar un ecosistema criminal dif\u00edcil de abordar.<\/p>\n\n\n\n

\u00abLa red de droppers es una parte de la infraestructura que facilita las operaciones <\/strong>de muchos grupos de cibercriminales\u00bb, destaca J\u00e9r\u00f4me Saiz.<\/p>\n\n\n\n

Al atacar esta\u00a0herramienta<\/strong>, las fuerzas del orden \u00abcrean un efecto de palanca\u00bb que \u00abcorta las alas a los atacantes con la m\u00e1xima flexibilidad\u00bb, concluye.<\/p>\n\n\n\n
