In 2013-2014, Yahoo suffered one of the largest data breaches in history. The breach affected all three billion user accounts and compromised sensitive information such as names, email addresses, dates of birth, phone numbers, and security questions. The hackers responsible for the breach were able to gain access to Yahoo’s internal systems by exploiting a vulnerability in their software.
The impact of this breach was significant as it not only affected Yahoo users but also other companies that had partnered with Yahoo such as AT&T and Verizon. The incident resulted in a loss of trust among users and ultimately led to Verizon acquiring Yahoo at a reduced price.
Equifax Data Breach (2017)
In 2017, Equifax suffered one of the most significant data breaches in history affecting over 143 million customers worldwide. The hackers were able to exploit a vulnerability in Equifax’s web application software which allowed them to gain access to sensitive information such as social security numbers, birth dates, addresses and driver’s license numbers.
The impact of this breach was far-reaching with many customers suffering from identity theft or fraud due to their personal information being exposed. Equifax faced severe criticism for its handling of the incident which included delays in notifying customers about the breach.
WannaCry Ransomware Attack (2017)
In May 2017, WannaCry ransomware attack hit over 200 thousand computers across 150 countries causing widespread disruption across various industries including healthcare systems and government agencies. The ransomware was able to exploit a vulnerability in Microsoft Windows operating system and spread rapidly through networks.
