Descripción del ataque
El mes de agosto del 2023, se libero un boletin de ciberseguridad sobre la amenaza RHYSIDA. Dicha amenaza a comprometido a 81 victimas, se encuentra en linea y tiene el puesto 31 segun “Ransom-DB”. (https://www.ransom-db.com/ransomware-groups)
Se desconocen el origen y la identidad de Rhysida, pero algunas pistas sugieren que pueden tener su sede en Rusia o en la Comunidad de Estados Independientes, según el idioma y la zona horaria de sus comunicaciones con las víctimas. Por ejemplo, su software de ransomware contiene fragmentos de código y comentarios en ruso, y sus notas de rescate y su sitio de filtración utilizan palabras y frases en ruso. También evitan atacar a organizaciones en Rusia u otros países exsoviéticos.
La banda Rhysida no sólo ha atacado la Biblioteca Británica, sino que también ha lanzado otros ataques de alto perfil contra instituciones gubernamentales y sanitarias de todo el mundo. Algunas de sus víctimas anteriores incluyen:
- El ejército de Chile: en mayo de 2023, Rhysida pirateó el sitio web y el sistema de correo electrónico del ejército de Chile, cifró sus datos y exigió un rescate de 50 Bitcoin (alrededor de 1,9 millones de dólares). Rhysida también filtró algunos de los datos en su sitio de filtración, incluidos documentos militares e información personal de soldados y oficiales.
- Prospect Medical Holdings : En agosto de 2023, Rhysida atacó al grupo hospitalario estadounidense, cifró sus datos y exigió un rescate. Rhysida también amenazó con filtrar los datos de más de 200.000 pacientes y empleados, incluidos 500.000 números de Seguro Social, documentos corporativos y registros de pacientes. El grupo dijo que vendería los datos por 50 Bitcoin (alrededor de 1,9 millones de dólares) en su sitio de filtración, donde publicó muestras de los datos e inició una subasta.
- Ministerio de Salud de Kuwait: En julio de 2023, Rhysida pirateó el Ministerio de Salud de Kuwait, cifró sus datos y exigió un rescate de 50 bitcoins (alrededor de 1,9 millones de dólares). Rhysida también filtró algunos de los datos en su sitio de filtración, incluidos registros médicos e información personal de pacientes y personal.
