Dado que hay variantes de TESLACRYPT-V, que no sobrescriben ni el nombre ni la extensión del fichero que codifican con RSA4096, conviene saber que donde ha cifrado ficheros ha dejado su huella en tres ficheros de nombre

What’s the matter with your files?
Your data was secured using a strong encryption with RSA4096.
Use the link down below to find additional information on the encryption keys using RSA4096:https://en.wikipedia.org/wiki/RSA_(cryptosystem)
What exactly that means?
It means that on a structural level your files have been transformed. You won’t be able to use, read, see or work with them anymore.
In other words they are useless, however, there is a possibility to restore them with our help.
What exactly happened to your files?
*** Two personal RSA4096 keys were generated for your PC/Laptop; one key is public, another key is private.
*** All your data and files were encrypted by the means of the public key, which you received over the web.
*** In order to decrypt your data and gain access to your computer you need a private key and a decryption software, which can be found on one of our secret servers.
What should you do next?
There are several options for you to consider:
1. You can wait for a while until the price of a private key will raise, so you will have to pay twice as much to access your files or
2. You can start getting BitCoins right now and get access to your data quite fast.
In case you have valuable files, we advise you to act fast as there is no other option rather than paying in order to get back your data.

Con el actual ELISTARA vamos implementando las modificaciones para poder detectar y eliminar las nuevas variantes que van apareciendo, si bien en algunos casos no crean clave de lanzamiento para próximos reinicios, ni el fichero malware en ruta típica donde acostumbran a ser ubicados, sino que el fichero lo descargan en “Mis documentos”, quedando allí aparcado hasta que un día el mismo usuario lo ejecute y vuelva a cifrar los ficheros de datos…
Es por ello, que para quien haya sufrido un TESLACRYPT y el ELISTARA no haya encontrado la clave indicada ni el fichero en cuestión, se ha añadido a la versión 8.8 del SPROCES (que ya está disponible) un listado de los ficheros EXE que haya en dicha carpeta, para poder pedir los sospechosos, para analizarlos y controlarlos, si procede.
De otra forma, podrían quedar malwares aparcados que podrían ser ejecutados
Con todo ello esperamos que, entre el ELISTARA, el SPROCES y nuestros técnicos, se puedan evitar catástrofes desesperarían a mas de uno.
A PESAR DE ELLO, MUCHO CUIDADO Y RECORDAR NO EJECUTAR FICHEROS NI LINKS ANEXADOS A MAILS NO SOLICITADOS !!!
