Figures released by Gemalto – the world leader in digital security – have revealed that 945 data breaches led to a massive 4.5 billion data records being compromised worldwide in the first half of 2018 – up by a staggering 133% compared to the same period in 2017.

 

Unknown number of compromised data records

A total of six social media breaches, including the Cambridge Analytica-Facebook incident, accounted for over 56% of total records compromised. Of the 945 data breaches, 189 (20% of all breaches) had an unknown or unaccounted number of compromised data records.

The Breach Level Index is a global database that tracks data breaches and measures their severity based on multiple dimensions, including the number of records compromised, the type of data, the source of the breach, how the data was used, and whether or not the data was encrypted. By assigning a severity score to each breach, the Breach Level Index provides a comparative list of breaches, distinguishing data breaches that are not serious versus those that are truly impactful.

Healthcare sector leads for number of incidents

Most sectors saw an increase in the number of incidents compared to the previous half – the exceptions were government, professional services, retail and technology, though both government and retail saw an increase in the number of records breached through fewer events.

Healthcare continues to lead in number of incidents (27%), whilst social media ranks top for number of records breached (56%) due to the high-profile customer data compromises at Facebook and Twitter, involving 2.2 billion and 336 million respectively.
