DISA Global Solutions, a leading US-based employee screening company, recently confirmed a significant data breach that compromised the personal details of over 3.3 million individuals. This breach has raised serious concerns about the security of sensitive personal information and the potential risks for affected individuals. Here’s a detailed breakdown of the incident, its immediate impact, and broader implications:
Overview of the Breach
Emergence and Tactics
- Hacker Identity: The breach was carried out by an unidentified hacker who managed to infiltrate DISA’s systems.
- Timeline: The cyberattack occurred on February 9, 2024. However, it remained undetected for more than two months. DISA identified the breach on April 22, 2024, following an internal investigation.
Details of the Breach
Data Compromised
