Researcher Drops YellowKey, GreenPlasma Windows Zero-Days

SecurityWeek

A security researcher has disclosed two serious vulnerabilities in Windows, known as YellowKey and GreenPlasma. YellowKey is a BitLocker bypass that allows unauthorized access to encrypted drives, but it requires physical access to the device. GreenPlasma, on the other hand, enables attackers to elevate their privileges to System level, potentially giving them full control over the affected system. These vulnerabilities pose a significant risk to users and organizations that rely on Windows for sensitive tasks. Companies should assess their physical security measures and apply necessary updates to protect against these risks.

Machine identities outnumber humans 109 to 1

Help Net Security

A recent report from Palo Alto Networks reveals that organizations currently manage an average of 109 machine identities for every human identity, with this number expected to rise significantly in the coming years. The report predicts an 85% growth in AI agents over the next year, contributing to a projected 77% increase in machine identities overall. In contrast, human identities are expected to grow by 56%. This imbalance raises concerns about how organizations are securing these machine identities, especially as they become more prevalent in business operations. The findings underscore the need for companies to enhance their identity security measures across the entire lifecycle of AI agents to mitigate potential risks associated with this rapid growth.
