Editor's Notes

The text is well-structured and follows the required sections for an attack summary. A few suggestions for improvement:

1. In the "Timeline" section, ensure all dates are in the format "Month day, year, time PM UTC:". For example, change "July 28, 2022, 05:11 AM UTC:" to "July 28, 2022, 05:11 AM UTC:".

2. Consider adding more details about the smart contract vulnerability that was exploited, if available. This would provide more context for the "Security Failure Causes" section.

3. Double-check the accuracy of the statement about the first malicious transaction time, as it could not be verified through the provided search results.

4. Minor grammatical correction: Change "Bridged of stolen funds" to "Bridging of stolen funds".

Overall, the text is informative and concise, providing a good overview of the Nirvana Finance attack.
