A major security flaw was recently uncovered in the Windows Wi-Fi driver, making it possible for hackers to break into PCs via wireless networks. This issue, now resolved, allowed malicious programs to be executed on vulnerable computers without requiring prior access.

Understanding the Flaw

The vulnerability, identified as CVE-2024-30078, was labeled “Important” by Microsoft. It allowed attackers within Wi-Fi range to send specially crafted network packets to a target computer, executing malicious code and bypassing all security checks without user intervention. This means that simply being connected to a Wi-Fi network at a café, airport, or hotel could expose your device to attack.
