How Data Breaches Happen, by Method
How 344 recorded data breaches break down by the method behind them. The source records the method as free text, so near-identical wordings are grouped here: "hacked" covers everything from a stolen password to a zero-day exploit, while "poor security" means data left openly accessible with no attack involved at all.
Analysis
Hacked accounts for 185 of the 344 recorded breaches, 53.8% of them and 3.8 times the 49 attributed to poor security. The 11 methods here cover 344 incidents, 100.0% of the list. Deliberate attacks are not the whole story: 108 incidents are attributed to poor security, accidents, lost devices or insiders. The smallest category on this chart has 3.
