What kinds of failure, how severe, in whose systems, and how do they happen?
124 cases. These are counts of documented cases, not rates of how often incidents happen.
What went wrong, and how severe
Segments are counts of cases; the number at the end of a bar is that class's cases.
Whose systems
No source names the developer in 43 of 124 cases; the table counts the other 81. Developers named in at least 3 cases are listed; the rest are grouped. A developer is named where the sources name one.

How they got in
No source says what set off 92 of 124 cases. Of the 32 that say, 9 do not say whose system it was. The chart shows the 23 cases that say both.
Counts of cases by what set the failure off, split by whose system it was.
Severity
| Severity | Cases |
|---|---|
| negligible | 6 |
| minor | 31 |
| moderate | 44 |
| major | 41 |
| severe | 2 |
Cases that state a dollar loss: minor 1 of 31 ($999.99 in total); moderate 1 of 44 ($15,000 in total). No negligible or severe case states a dollar loss. Cases with a stated loss in another currency, not converted and not added to the dollar figures: moderate 1 of 44; major 2 of 41.
A loss figure is added only over the cases that state one; it is not a total of all losses.
Who caught it
No source says who caught 56 of 124 cases. Of the other 68, the operator caught 27; outsiders, researchers or the victim caught 41. The bars show only those 68.

From when it happened to the earliest source we hold
The strip scrolls sideways: it runs to 353 days, the longest wait.
Each dot, in days, from the shortest wait to the longest: 1, 1, 2, 3, 5, 5, 7, 9, 10, 13, 18, 19, 25, 26, 49, 56, 60, 66, 81, 84, 98, 116, 126, 129, 131, 155, 155, 158, 249, 353.
Where the date is known (30 of 124 cases), the earliest source we hold is dated a median 52.5 days after it happened; the longest gap was 353 days. Cases that give only the month it happened, so no gap is counted: 5. Cases that never say when it happened: 89.
