The latest Security Affairs newsletter reports on two significant cybersecurity issues. First, OpenSSL has addressed a vulnerability known as the HollowByte memory exhaustion bug, which could lead to service disruptions. Users of OpenSSL, particularly those running servers or applications that rely on this library, should ensure they update to the latest version to avoid potential downtime or denial-of-service attacks. Additionally, researchers have discovered Daxin, a malware that has been linked to China, still active on a manufacturer's network despite being over a decade old. This finding raises concerns about the long-term persistence of such malware and its ability to evade detection. Companies must remain vigilant and conduct thorough network security assessments to identify and eliminate such threats.
