Fake upgrade to Windows 10 may come dearly


People's interest in the new operating system Windows 10 is trying to take advantage of the last days of cybercriminals. The unsolicited e-mails posing as a representative of Microsoft and encouraged recipients to a free update installed. But instead gullible downloaded to a computer virus extortion.


"Cybercriminals took advantage of the opportunity to send out fake e-mails that pretend to be a challenge for a free upgrade to Windows 10. In fact, hiding ransomware variant CTB locker," warned Paul Basta, a security analyst at the National Security Team CSIRT.CZ.

CTB locker malicious code can encrypt data stored on the hard disk and unlock their ransom demands in Bitcoin, calculated in terms of dozens of thousands.


Related viruses are hacked bonanza.


Ransom but people should not have to pay because they have no guarantee that the data will actually be made available. For similar cases that occurred in the past, even it shows that there is virtually never decrypt data. The only solution is a computer clean from virus.

People have a new trick can leave easily fooled, because the update for Windows 10 from earlier versions of the system is really free. When booking a free upgrade moreover really on the US software giant fills mailbox address, so people quite logically expect that more information will come via e-mail.


Extortionists targeting on mobile phones


Last year, he also appeared renewal of the threat that targeted the smartphones with the Android operating system. Security experts this uninvited visitor named Simplocker.

Uninvited visitor called Simplocker according to an analysis by security experts hid in Sex xionix for devices with Android operating system. It should be noted that this program is not in the legitimate Google Play Store, but unofficial sources, especially various internet forums.

The sample revealed in Sex xionix communicates with users in Russian, ransom to be paid in Ukrainian talents. If people are the equivalent of almost CZK 500 will pay, but not, as in the case of CTB LOCKER no assurance that their data is actually accessed, as well as in the version for classical computers.

Related viruses are hacked literally a gold mine. In just one day, this way they are able to easily earn several hundred thousand, as previously revealed in their statistics antivirus company Symantec.
