BASKING RIDGE, N.J. - The Verizon Business 2021 Data Breach Investigations Report (2021 DBIR) examines more breaches than ever before, and sheds light on how the most common forms of cyber attacks affected the international security landscape during the global pandemic. This year’s report saw 5,258 breaches from 83 contributors across the globe, a third more breaches analyzed than last year.
A summary of the facts revealed in the report include:
With an unprecedented number of people working remotely, phishing and ransomware attacks increased by 11 percent and 6 percent respectively, with instances of Misrepresentation increasing by 15 times compared to last year. Additionally, breach data showed that 61 percent of breaches involved credential data (95 percent of organizations suffering credential stuffing attacks had between 637 and 3.3 billion malicious login attempts through the year).
The report also highlighted the challenges facing businesses as they move more of their business functions to the cloud - with attacks on web applications representing 39% of all breaches.
“The COVID-19 pandemic has had a profound impact on many of the security challenges organizations are currently facing,” said Tami Erwin, CEO, Verizon Business. “As the number of companies switching business-critical functions to the cloud increases, the potential threat to their operations may become more pronounced, as malicious actors look to exploit human vulnerabilities and leverage an increased dependency on digital infrastructures”.
This year, the Incident Classification Patterns the DBIR report team uses to classify security threats have also been improved and refreshed. The updated report patterns explain 95.8 percent of analyzed breaches and 99.7 percent of analyzed incidents over all time, and should provide customers with a better understanding of the threats that exist, and how their organizations can best avoid them.
The 2021 DBIR includes detailed analysis of 12 industries, and shows that, while security remains a challenge across the board, there are significant differences across verticals. For example, in Financial and Insurance industries, 83 percent of data compromised in breaches was personal data, whilst in Professional, Scientific and Technical services only 49 percent was personal. Further highlights include:
The 83 contributors involved with the 2021 DBIR have provided the report with specific insights into regional cyber-trends highlighting key similarities and differences between them.
Alex Pinto, Lead Author of the DBIR, comments, “When you read the contents of the report, it is tempting to think that a vast array of threats demands a sweeping and revolutionary solution. However, the reality is far more straightforward. The truth is that, whilst organizations should prepare to deal with exceptional circumstances, the foundation of their defences should be built on strong fundamentals - addressing and mitigating the threats most pertinent to them.”
