Yes, you are reading it right. The computer search engine ShodanHQ, has indexed 3,221 Windows XP machines in their public database. This means, that there are 3,221 vulnerable Windows XP hosts which can be directly attacked by cybercriminals and hackers.
The cybercriminals and hackers will try to add the hijacked Windows XP machines to their botnet, allowing them to perform stronger attacks, generate more bit coins, and get access to various data like personal information, credentials and financial information.
If you know someone, which still uses Windows XP, then please inform them about the risks they are taking by using such an old and unsecure operating system.
Did you know that the USA military has paid Microsoft millions of dollars just to support the Windows XP machines which are still being used by the USA military?!
