The CVSS […]
Secret Life of Enterprise Botnets The Secret Life of Enterprise Botnets is a speech in a session of RSA Conference 2023 by Dr. Craig Labovitz, Head of Technology for the Deepfield business unit at Nokia. In collaboration with global Internet providers, researchers tracked more than 500,000 compromised enterprise servers, security cameras and IoT (HVAC, PoS, […]
According to Gartner’s supply chain security risk report in 2021[1], breaches of confidential or sensitive information constitute another major factor contributing to software supply chain risks. Hackers steal hard-coded credentials in source code, building logs, and infrastructure, such as API keys, encryption keys, tokens, and passwords, or locate vulnerabilities in a leaked software bill of […]
Overview On May 10, NSFOCUS CERT monitored that Microsoft had released a security update patch for May, which fixed 38 security issues, involving Win32k, Windows OLE, Microsoft SharePoint Server, Windows Pragmatic General Multicast (PGM) and other widely used products, including high-risk vulnerability types such as privilege enhancement and remote code execution. Among the vulnerabilities fixed […]
