Sex, Exploit Kits and Ransomware

Each of us has his own preferences: some people love Lady Gaga or Justin Bieber, others Rocco Siffredi or Laura Lion. The love for the latter can be dangerous if you are not aware of security problems when you have a non-updated system, and it's possible you end with an infected system asking for money to recover the control of the machine.



This was an interesting situation so I tried to help my friend. In this case, just after the desktop appeared, a full-screen window showed. It was a warning from the Spanish police ("Cuerpo Nacional de Policía") saying that the system had been blocked because it had been used to perpetrate illegal actions like child pornography, terrorism and violence against children: "Fue detectado un caso de actividad ilegal. El sistema operativo fue bloqueado por violación de las leyes de España!". A warning like this can be shocking for a normal user, so social engineering was working here. However, this warning was also asking for 100€ to be paid via Ukash or Paysafecard as a fine for this behaviour and in order to restore the system. This part can be a bit strange and maybe makes the victims call the police very quickly. Once this window appeared no other action was possible, like execute the Task Manager or return to the desktop, just enter a code to pay.
