The attack caused thousands of injuries and nine fatalities, making it one of the most discussed governmental breaches.
The U.S. Presidential campaign breach of 2024 is ranked as the second largest breach. Hackers accessed both Trump’s and Biden’s campaigns, creating a serious risk to politics. Although the exact number of individuals impacted remains unknown, its political importance made it newsworthy, with over 80,000 reports.
