The Biggest Data Breaches by Region & Sector
Data security is one of the largest concerns impacting the world today. As we are storing and a heavily relying on computers and smartphones it poses a number of potential threats to the data we are storing. Data can get lost due to system failure, corrupted by a computer virus, deleted or altered by a hacker. The increasing sophistication of cyber-attacks coupled with the overall lack of cybersecurity has led to the greatest data breaches and the loss of data records on a global scale.
Some facts on data breaches:
· Over 14,717,618,286 records have been lost or stolen since 2013 due to data breaches.
· 3,353,178,708 records were compromised in the first half of 2018.
· In 2017, 86% of all breaches worldwide occurred in North America.
· One year later, 45.9% of data breaches in the US were in the business sector.
Cybercriminals exposed 2.8 billion consumer data records in 2018, costing more than US$654 billion to U.S. organizations and in Q1 2019 cyberattacks on US financial services organizations alone cost the industry US$6.2 billion up from just US$ 8 million in Q1 2018
- Weak and Stolen Credentials, a.k.a. Passwords – A weak or lost password that is the vulnerability that is being exploited by the opportunist hacker. Stats show that 4 in 5 breaches classified as a “hack” in 2012 were in-part caused by weak or lost (stolen) passwords
- Back Doors, Application Vulnerabilities – Flaws in software applications which are poorly written or network systems which are poorly designed or implemented, they leave holes that hackers get easy access to your data
- Malware – Malware is, by definition, malicious software: software loaded without intention that opens up access for a hacker to exploit a system and potentially other connected systems.
- Social Engineering – It is a technique used by hackers by persuading others with a more legitimate claim to the much sought after data, to create it for you?
- Insider Threats – The rogue employee, the disgruntled contractor or simply those not bright enough to know better have already been given permission to access your data.
