In the last week Windows 10 has been in the news in all the places where technology is discussed and it is not for less, it is the new Microsoft operating system that can be obtained for free as an update if you already have Windows 7 or Windows 8.
So millions of people around the world are installing it and cybercriminals have not missed the opportunity.
The update was released on July 29 but did not arrive at the same time for all users and the boys started sending fake emails as spam under the subject Upgrade to Windows 10 for free.
In the email that pretended to be sent by Microsoft, a supposed installer was attached, which actually ended up installing a ransomware known as CTB-Locker.
These programs are those that block the computer in exchange for a ransom and if it is not paid in 2 or 3 days the computer is completely blocked or all files are lost. Today these ransomwares are a real problem, until not long ago they pretended to lock the computer and it was easy to get rid of them without paying, but now they really encrypt all files in such a way that they can only be recovered with a key that criminals send after the pay.
I am sure some of them must be generating hundreds of dollars or thousands a day and they have managed very well to remain anonymous.
In the Cisco blog they have published details about this attack that was not the only one, in the Kaspersky laboratories they have also found another campaign like this where cybercriminals from Brazil have cloned the Microsoft website to spread a Trojan:
Windows activators and keygens have always been a problem because most come with hidden gifts that keep the computer infected without its owners knowing. With Windows 10 at least many will get rid of this, but still you have to be careful not to be fooled.
