NASA AIT-GUI Flaws Could Let Unauthenticated Attackers Issue Spacecraft Commands

The Hacker News

Security researchers from Cycode have discovered significant vulnerabilities in the AIT-GUI, which is NASA's browser-based operator console for the AMMOS Instrument Toolkit. These flaws allow unauthenticated attackers to send arbitrary commands to spacecraft and instrument command buses. The vulnerabilities, assigned the identifier GHSA-p9r8-2q67-fp86, have a high severity rating of 9.4 on the CVSS scale, indicating they pose a serious risk. This situation is alarming as it could potentially allow unauthorized access to critical spacecraft operations, which could disrupt missions or lead to unintended consequences. Organizations using AIT-GUI should prioritize addressing these vulnerabilities to safeguard their systems.

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.
