New Manic Android malware can exfiltrate data through nearby devices

BleepingComputer

A new Android malware called Manic has emerged, targeting users across several European countries. This malware is particularly concerning because it can exfiltrate data not just through traditional means, but also by leveraging nearby infected devices. This makes it more difficult for users to detect and defend against. Researchers have identified the malware's ability to communicate with other compromised devices, potentially allowing attackers to gather sensitive information from a wider network of victims. This situation raises alarms about the security of Android devices and the need for users to be vigilant about app permissions and device security.

Police Are Hiding Their Use of Flock Surveillance Cameras

Schneier on Security

In Wapello County, Iowa, a policy regarding the use of Flock license plate reader cameras has come to light, revealing that police are instructed to keep their usage a secret from the public. The policy explicitly directs officers not to mention the Automated License Plate Recognition (ALPR) technology to individuals during stops or in their reports unless absolutely necessary. This raises concerns about transparency and accountability in law enforcement practices. The use of such surveillance tools without public awareness parallels past incidents involving IMSI-catchers, which were similarly concealed. The implications of this secrecy affect public trust and raise questions about the balance between security and individual rights.

OpenAI previews privacy-focused system for detecting AI misuse

Help Net Security

OpenAI is introducing a new system called Private Safety Processing, aimed at enhancing privacy and security as AI technology continues to develop. This system is designed to detect patterns in user interactions while ensuring that OpenAI staff cannot access the actual content of those interactions. The initiative is in response to concerns from early customers about data protection and misuse of AI systems. OpenAI plans to roll out this system and release a technical white paper in September to provide further details. This move reflects a collaborative approach to addressing the challenges posed by advanced AI capabilities, emphasizing that no single company can tackle these risks alone.
