From the Marriott International hotel breach, which impacted half a billion customers, to the highly-profile scandal in which a political consulting gained access to Facebook users’ information, major corporations are increasingly victims of large hacks or bungling the data they store.

Daniel Markuson, blog editor at NordVPN, a virtual private network service provider based in Panama, released a review of 11 of the worst data breaches last year. No company is immune to data breaches, which is particularly concerning as corporations continue to collect more data from users.

“The scope of these attacks shows that even the biggest corporations are vulnerable and are prone to errors,” he said. “This means that it’s becoming more difficult to trust them as we never know when our data is going to end in the wrong hands.”

Here’s a look at last year’s biggest breaches and vulnerabilities ranked by the number of people impacted, as determined by NordVPN:

1.Marriott International (500 million users)

2.Twitter (330 million users) The company said it mistakenly stored user passwords in plain text on an internal log accessible only to employees, and that no outsiders accessed them

3.My Fitness Pal (150 million users)

4.Facebook (147 million users in multiple breaches)

5.Firebase (100 million users)

6.Quora (100 million users)

7.MyHeritage (92 million users)

8.Uber (57 million users)

9.Ticket Fly, owned by Eventbrite (27 million users)

10.Google+ (500,000 users)

11.British Airways (380,000 users)

从影响5亿客户的万豪国际酒店数据泄露到引人注目的Facebook数据泄露丑闻（一家政治咨询公司获得了访问Facebook用户信息的渠道），各大公司正日渐受到大规模黑客攻击或储存数据保管不当的侵害。

巴拿马虚拟私营网络服务提供商NordVPN的博客编辑丹尼尔·马库森在去年对11起最严重的数据泄露事件进行了盘点。没有公司能够避免数据泄露，随着公司继续搜集更多的用户数据，这一点尤为令人担忧。

他说：“这些攻击的范围证明，即便是那些超大型公司也存在漏洞，而且容易出错。这意味着人们以后更难以信任那些大公司，因为我们不知道自己的数据哪一天便会落入不法分子手中。”

以下是去年最严重的泄露和漏洞事件，由NordVPN按照受影响人群数量排序：

1. 万豪国际集团（5亿用户）

2. 推特（3.3亿用户）公司称自己错误地将其用户密码以纯文本的形式储存在仅供雇员访问的内部日志中，而且外部人士没有访问权限

3. My Fitness Pal（1.5亿用户）

4. Facebook（多次泄露，共计1.47亿用户）

5. Firebase（1亿用户）

6. Quora（1亿用户）

7. MyHeritage（9200万用户）

8. Uber（5700万用户）

9. Ticket Fly，Eventbrite子公司（2700万用户）

10. Google+（50万用户）

11. 英国航空（38万用户）
