The number of records exposed in data breaches and leaks has surged to
36 billion so far this year, across almost 3,000 separate incidents,
further extending 2020s status as the worst year on record.

Although businesses sustained an onslaught during the first two
quarters of 2020, the last three months added an additional 8.3
billion exposed records to the tally, with the 36 billion total
representing twice the number of records leaked throughout 2019.

Two breaches alone exposed over a billion records each, while four
breaches exposed over 100 million records together, accounting for
22.3% of Q3 records exposed, according to research by Risk Based
Security. The largest incident of Q3 is attributed to an open
Elasticsearch server, which exposed six billion records, though the
6.4TB of data included multiple interactions with the same client,
meaning roughly 700,000 individuals were affected.

“The quagmire that formed in the breach landscape this Spring has
continued through the third quarter of the year,” said executive vice
president at Risk Based Security, Inga Goddijn.


“Breach disclosures continue to be well below the high water mark
established just last year despite other research indicating the
number of attacks are on the rise. How do we square these two
competing views into the digital threat landscape?”

Though the number of exposed records has risen drastically, there’s
been a decline in the number of publicly disclosed breaches. For Q3 in
2019, there were 6,021 data breaches reported by this point in the
year, but only 8.3 billion records were exposed.

Goddijn argues these trends could be explained by a reduced level of
media coverage, although another factor is the pivot by hackers to
more lucrative ransomware attacks, with companies not always having
the obligation to report the incident publicly, particularly in
jurisdictions outside the EU.

Indeed, ransomware has been involved in 21% of reported breaches
during 2020, with 440 incidents this year including ransomware as a
component. It should also be noted that rules governing when an
organisation must notify authorities over a data breach are different
in the US and Europe, with American businesses not bound by the strict
reporting demands set out under GDPR.

The vast majority of incidents (77.5%) were attributed to ‘outside’
hackers or cyber criminals. Of the 17% that originated from within the
organisation, 67% of those were deemed the result of human error,
including missing devices or misconfigured databases, while 13% were
regarded as malicious.


Some major 2020 incidents include an attack on fitness technology app
Kinomap in April, leading to the exposure of 42 million records. In
March, printing company Doxzoo inadvertently exposed 343GB of data
through a misconfigured AWS S3 bucket, including sensitive information
relating to branches of the UK and US military.

Only last month human error was blamed for the exposure of data
belonging to 18,000 Welsh residents who had tested positive for
COVID-19, which was leaked for 20 hours on a public-facing server.
This incident, although smaller in scale, represented a raised threat
due to the sensitive nature of the data exposed.
