About 47.5% of the breaches that led to customer data being exposed, plus 68.2% of the actual breached data, was recorded in the US.
Globally there were a total of 4149 breaches which led to the exposure of more than 4.2 billion records, approximately 3.2 billion more than the previous high in 2013.
More than half of reported breaches — 53.3% — were the result of hacking, which accounted for 91.9% of the exposed records.
In those 2000 breaches, American organisations lost a total of more than 2.9 billion user records. This was more than 10 times as many as were lost in Russia, which was the second biggest loser.
One reason for the US having such a large number of personal records lost was due to the announcement of two massive breaches by Yahoo! – 500 million in September and a billion in December. The second breach reported by Yahoo! is the largest on record.
If the Yahoo! numbers were subtracted from the US total, the country still was the leader in number of breached rec cords, though the difference with Russia was five to one.
The business sector saw 51% of reported breaches, followed by unknown categories (23.4%), government (11.7%), medical (9.2%), and education (4.7%).
Malware accounted for 4.5% of the reported breaches, but represented just 0.4% of the records compromised.
