U.S. Government Entity Paid Kairos $1 Million in Data-Theft Extortion Case

The Hacker News

A U.S. government entity has reportedly paid around $1 million to a group named Kairos to prevent the release of stolen data. This situation arose from a data theft incident where sensitive files were taken, and negotiations revealed the payment through leaked chat logs and blockchain tracking. Interestingly, it appears that Kairos may not operate like traditional ransomware groups, as there is no evidence of them locking files or demanding ransom in the typical sense. This incident raises concerns about how government entities handle data breaches and the potential for attackers to exploit these situations for financial gain. The event reflects the growing challenge of data protection in the public sector and the lengths to which organizations may go to safeguard sensitive information.

Flock Cameras Can Surveil Cars Without License Plates

Schneier on Security

Flock Safety, a surveillance camera company, has introduced a new feature that allows law enforcement to identify vehicles even when they lack visible license plates. This system, referred to as a ‘Vehicle Fingerprint’, collects data on a vehicle’s decals, bumper stickers, and other unique identifiers, enabling officers to gather more information without complete plate details. Additionally, the technology supports a 'multi geo search', helping police track multiple vehicles believed to be traveling together. This development raises concerns about privacy and the extent of surveillance capabilities available to law enforcement, as it could lead to increased monitoring of individuals who are not necessarily under investigation. As law enforcement agencies adopt these technologies, the implications for civil liberties and personal privacy will be significant.
