The Internet becomes a fairly dangerous part day by day and especially for those who use it from third party applications. The latest bad news is that the largest and most widely used free public DNS (Domain name system) of her Google yesterday became hijacked.
DNS is the list of Internet addresses, which translates into IP addresses in readable form and vice versa. According to BGPmon, which tracks changes to the internet, Google's DNS server 8.8.8.8 / 32 has been hijacked yesterday for 22 minutes.
Google's DNS server handles about 150 billion queries per day and during its 22 minutes piracys, millions of Internet users, was headed for Latin America, Venezuela and Brazil.
The hackers εκμεταλλεύτηκαν μια γνωστή ευπάθεια του λεγόμενου πρωτόκολλο συνοριακής πύλης ή Border Gateway Protocol (BGP), το οποίο χρησιμοποιείται για την ανταλλαγή data between major service providers, and hijacking allowed attackers to change and direct traffic to a router that was already theirs.

Η attack BGP is a man-in-the-middle attack on a larger scale and harder to detect, since the traffic still reaches its legitimate destination. This particular attack was first presented by two security researchers – Tony Kapela and Alex Pilosov, as reported by the The Hacker News.
