Hackers could spy on cell phone users by abusing 5G baseband flaws, researchers say

Penn State researchers disclosed 12 vulnerabilities in 5G basebands from Samsung, MediaTek, and Qualcomm that allowed phones to be tricked into connecting to fake base stations and be silently exploited — enabling phishing, credential theft via malicious sites, and protocol downgrade to facilitate eavesdropping. The team released a tool (5GBaseChecker) to aid further research and reported that most affected vendors have issued patches.
