The SMS abuser “899991” message

Many of our users received an Extortion SMS Message with the following text:

Desafortunadamente, tengo mas noticias para ti. Hace varios meses, tuve acceso al dispositivo que esta utilizando para navegar por Internet. Desde entonces, he estado monitoreando su actividad en Internet. Como visitante habitual de sitios para adultos, puedo confirmar que usted es responsable de esto. Para simplificar las cosas, los sitios web que ha visitado me han proporcionado acceso a sus datos. Cargue un caballo de Troya basado en el controlador que actualiza su firma varias veces al dia, para que sea imposible que el antivirus lo detecte. Ademas, me da acceso a su camara y microfono. Ademas, hice una copia de seguridad de todos los datos, incluidas fotos, redes sociales, chats y contactos. Recientemente, tuve una idea increible de crear el video que disfrutas en una parte de la pantalla, mientras el video se reproducia simultaneamente en otra pantalla. !Fue divertido! Asegurese de que pueda enviar facilmente este video a todos sus contactos con solo unos pocos clics, y supongo que le gustaria evitar este escenario. Con eso en mente, aqui esta mi propuesta: transfiera la cantidad equivalente a 1300 USD a mi billetera Bitcoin y me olvidare de todo. Tambien eliminare permanentemente todos los datos y videos. En mi opinion, este es un precio algo modesto por mi trabajo. Puedes averiguar como comprar Bitcoins usando buscadores como Google o Bing, ya que no es muy dificil. Mi billetera Bitcoin (BTC): 1F34gHWdSXVnN5zy5mA7gEaKgeu8NGPHCw Tiene 48 horas para responder y tambien debe tener en cuenta lo siguiente Tampoco tiene sentido quejarse, ya que no se puede rastrear la carta junto con mi billetera Bitcoin. Todo fue orquestado con precision. Si detecto que mencionaste algo sobre esta carta a alguien, el video se compartira de inmediato y tus contactos seran los primeros en recibirlo. !Entonces el video se publicara en la web! !Buena suerte y tomatelo con calma! Fue solo mala suerte, la proxima vez, ten cuidado.


After the disguised 1f34ghwdsxvnn5zy5ma7geakgeu8ngphcw Bitcoin SMS Trojan has been downloaded on the machine, the victims will usually be requested to allow it to make system changes. Some Trojans may also ask for administrative rights. 

At this point, of course, the victims believe they’re operating a legitimate app and will typically grant it all permissions needed to run the file. And this is how the Trojan gains complete control of the machine and starts to run its stealthy criminal agenda.

The activities that threats like 899991, “You still have not paid the requested amount of $ 250.“, “You’ve Been Hacked” can run once inside the device, however, are often unknown, since they can be very versatile. In general, each Trojan-based threat can be programmed to perform different criminal tasks. For instance, 899991 may be set to spy on its victims and, in this case, it will silently keep track of the keystrokes, the screen, the online and offline activities of the users without showing any indications of its presence. In this way, the hackers can collect valuable information about the victims and determine how to exploit it in their own interests.

Money extortion is just one of the follow-up to the fact that your device has been compromised by a Trojan that is secretly transferring your information to people with malicious intentions. If they get their hands on your credit or debit card details, they may empty your bank accounts ballances before you even known it.

However, espionage is not the only way to employ such a virus. Trojans such as 899991 are also used to distribute other malicious programs to the victims’ machines. Thanks to their backdooring ability, these threats may insert root kits, Ransomware cryptoviruses, different phishing applications and spyware into the system without the knowledge of the victim. They may also block the existing security program from doing its job in order to allow other malware to slip in.

Sometimes, the Trojan infections may obtain administrative rights over the OS and use them to trigger a variety of resource-intensive processes on the attacked device. In such situations, the victims may experience a significant slowdown of the device’s speed and even crashes, screen-freezing issues, or other software and system disruptions and errors, most of which may be a result from the Trojan’s excessive system resources exploitation.

Sadly, in most of the cases, there will be no visible symptoms of the harmful activities that threats like 899991 are performing. That’s why your best chances to detect and remove the malware on time is to use a reliable antivirus program that can scan your entire device.

Fight the virus

If you haven’t been notified of this hazard on time by your antivirus, then this might be due to the inability of the security program to detect the Trojan in its virus definition databases. Indeed, it may take some time for new threats like 899991 to be added to the virus databases of security programs and during that time, they may be invisible for the antivirus apps. That’s why, in such as scenario, it’s better to use a manual removal guide such as the one that you can find below and maybe update your anti-malware tool with a more-robust one that can remove 899991 immediately.
