The FBI is investigating a sophisticated cyber attack on an internal system containing sensitive surveillance information, including pen register data and personal details from investigations. The breach was discovered February 17 when agents noticed abnormal network activity. Hackers used advanced techniques and exploited a commercial internet provider's infrastructure to penetrate FBI security controls. The compromised system holds law enforcement data like phone surveillance records and personally identifiable information about investigation subjects. While the FBI confirmed the incident and says it addressed the suspicious activities, officials haven't identified who's responsible or revealed the full scope of the breach. **Source:** [Security Week](https://www.securityweek.com/fbi-investigating-suspicious-cyber-activity-on-system-holding-sensitive-surveillance-information/)
