Cybersecurity Ventures projects $6 trillion in annual losses due to cyberattacks in 2021, doubled since 2015. Statistics never lie and most Cybersecurity data breach stats are hard to absorb, but still, they project the need for secured infrastructures free from any potential threats.
Although we cannot list each and every breach in a single article because thousands of data breaches happen every day. However, we have collected some of the biggest breach stats from the recent decade till the year 2021.
So, let’s dive straight into the data, facts and stats
Biggest Breaches of Last Decade
Industry data shows that 47% of cyberattacks target small businesses because they are more vulnerable, the biggest breaches mostly include popular companies across the globe that hold data from millions of users. Here are a few of them:
- Yahoo Data Breach
- Year Occurred: 2013
- Breach Impact: 3 Billion accounts
Yahoo marks one of the largest breaches of the 21st century. Although the initial breach happened in 2013 it was almost four years until Yahoo analyzed the actual number of leaked account information. Verizon started investigating the breach and according to their initial investigation, records of 1 Billion accounts were leaked.
The company later came up with another report where they represented the actual figures of leaked accounts that were over 3 Billion. The breach allowed hackers to leak all the security questions and other sensitive information, but passwords and bank account details were not leaked during the breach.
It took almost four years for Yahoo to measure the extent of this breach. Verizon continued their investigation and they suggested security guidelines to make yahoo more secure for users.
- LinkedIn Data Breach
- Year Occurred: 2021
- Breach Impact: 700 Million accounts
This is one of the biggest and most recent data breaches that caused unrest in the cybersecurity space. In June 2021, a Dark Web forum advertised the sale of 700 million LinkedIn user profiles.
There are 756 million users in total on LinkedIn, and this exposure impacted 92% of them.
First, 500 million users were exposed, then 700 million in a second dump in which the hacker “God User” advertised selling the data.
Nevertheless, LinkedIn stated that the breach was regarded as a violation of its TOS rather than a data breach since no sensitive, private personal data was exposed.
God User posted a scraped data sample that contained email addresses, phone numbers, geolocation data, genders, and other social media details, giving malicious actors plenty of information to create follow-on social engineering attacks following the leak.
- Facebook Data Breach
- Year Occurred: 2019
- Breach Impact: 533 Million Users
According to UpGuard Cyber Risk, two third-party Facebook apps datasets were exposed online in April 2019. It contains over 533 million records and weighs in at 146 gigabytes, including comments, likes, reactions, account names, Facebook IDs and more, and it originated from Cultura Colectiva in Mexico.
Since many phone numbers were available on the dark web due to the incident, Troy Hunt added a feature to his HaveIBeenPwned (HIBP) compromised credential checking service that would allow users to verify whether their numbers were exposed or not.
People’s profiles were scraped by “malicious actors” with the help of Facebook’s contact importer tool, which helps them find their friends on the social network. Data collection doesn’t seem to have taken place before September 2019, but Facebook says it did prior to that.
- First American Corp. Breach
- Year Occurred: 2019
- Breach Impact: 885 million users
A leak of more than eight million sensitive records, including bank account information, social security numbers, wire transfers, and mortgage paperwork, was reported by First American Financial Corporation on May 8.
Insecure Direct Object Reference (IDOR) is a relatively common website design error related to First American Financial. It is important to note that a link to a web page containing sensitive information is created and intended only for one particular party to see; however, there is no method of verifying the identity of the viewer. By changing the link, anyone can view all documents on the website, including the one they discover through a link to a single document.
Among the exposed files are wire transaction records with bank account numbers and other information from home or property buyers and sellers. This data can be misused by hackers or other third parties to target users.
- Twitter Data Breach
- Year Occurred: 2018
- Breach Impact: 330 million users
Twitter notified its users about a technical glitch in May 2018 that led to passwords being stored unencrypted in an internal log. All passwords were accessible within the company’s internal network.
There was no indication of misuse or breach of any kind after Twitter notified its 330 million users that their passwords should be updated. The company said it’s fixed the bug and that no evidence of a breach was found, but recommended password changes as a precaution.
Neither Twitter nor the company disclosed a specific number of users who were affected but did say the number was considerable and that they were exposed for months.
- Adobe Data Breach
- Year Occurred: 2013
- Breach Impact: 152 million users
Adobe confirmed in 2013 that at least 38 million users were impacted by the recent data breach that exposed user account information and caused a flood of password reset emails. In addition, the already massive leak of source code at Adobe also extends to Photoshop products.
Aside from inactive Adobe IDs, Adobe IDs with invalid encrypted passwords, and test account data, the attackers obtained many invalid Adobe IDs from the company. Acrobat and Reader source code as well as ColdFusion Web application source code were stolen in the Adobe breach.
Other Shocking Data Breach Statistics
Despite these big data breaches, the PurpleSec’s Statistics Report also reveals some of the most recent and surprising data regarding various attacks and their impact on companies. According to their data, the Ransomware attacks increased by 350% in 2018 while malware attacks touched a figure of 812.67 million in the same year. There is a lot more data available in this statistical report.
AppSec Phoenix’s All-In-One Solution — Prevents Breaches
