Another day, another cyberattack. The U.S. Securities and Exchange Commission recently disclosed that its EDGAR database, which compiles filings from thousands of public companies, fell prey to a data breach. Hackers exposed a vulnerability in the system that allowed non-public information to be exploited. The SEC is currently investigating if illegal trading occurred based on the stolen information. 

The breach follows a recent hack at credit reporter Equifax (EFX) - Get Report  which resulted in the personal information of 143 million Americans, including Social Security and credit card numbers, to be put at the mercy of cyberattackers. 

But the SEC and Equifax hacks are far from the first time your information may have been put at risk. Yahoo, Ebay (EBAY) - Get Report and Microsoft-owned Linkedin (MSFT) - Get Report have all been subject to data breaches in recent years. 

Are cyberattacks becoming the new norm rather than an isolated occurrence? We took a look at the biggest hacks in the past few years.
