Fuzzing | Breaking Cybersecurity News | The Hacker News

A group of academics has disclosed details of over 100 security vulnerabilities impacting LTE and 5G implementations that could be exploited by an attacker to disrupt access to service and even gain a foothold into the cellular core network. The 119 vulnerabilities , assigned 97 unique CVE identifiers, span seven LTE implementations – Open5GS , Magma , OpenAirInterface , Athonet , SD-Core , NextEPC , srsRAN – and three 5G implementations – Open5GS, Magma, OpenAirInterface, according to researchers from the University of Florida and North Carolina State University. The findings have been detailed in a study titled "RANsacked: A Domain-Informed Approach for Fuzzing LTE and 5G RAN-Core Interfaces." "Every one of the >100 vulnerabilities discussed below can be used to persistently disrupt all cellular communications (phone calls, messaging and data) at a city-wide level," the researchers said. "An attacker can continuously crash the Mobility Management En...

Google has revealed that its AI-powered fuzzing tool, OSS-Fuzz, has been used to help identify 26 vulnerabilities in various open-source code repositories, including a medium-severity flaw in the OpenSSL cryptographic library. "These particular vulnerabilities represent a milestone for automated vulnerability finding: each was found with AI, using AI-generated and enhanced fuzz targets," Google's open-source security team said in a blog post shared with The Hacker News. The OpenSSL vulnerability in question is CVE-2024-9143 (CVSS score: 4.3), an out-of-bounds memory write bug that can result in an application crash or remote code execution. The issue has been addressed in OpenSSL versions 3.3.3, 3.2.4, 3.1.8, 3.0.16, 1.1.1zb, and 1.0.2zl. Google, which added the ability to leverage large language models (LLMs) to improve fuzzing coverage in OSS-Fuzz in August 2023, said the vulnerability has likely been present in the codebase for two decades and that it "wo...

Most microsegmentation projects fail before they even get off the ground—too complex, too slow, too disruptive. But Andelyn Biosciences proved it doesn't have to be that way.  Microsegmentation: The Missing Piece in Zero Trust Security   Security teams today are under constant pressure to defend against increasingly sophisticated cyber threats. Perimeter-based defenses alone can no longer provide sufficient protection as attackers shift their focus to lateral movement within enterprise networks. With over 70% of successful breaches involving attackers moving laterally, organizations are rethinking how they secure internal traffic.  Microsegmentation has emerged as a key strategy in achieving Zero Trust security by restricting access to critical assets based on identity rather than network location. However, traditional microsegmentation approaches—often involving VLAN reconfigurations, agent deployments, or complex firewall rules—tend to be slow, operationally disrupt...
