Zero-day vulnerability in Windows

Cyber security experts have found a zero-day vulnerability in Windows, allowing attackers to gain higher privileges on the target machine and dodging protection mechanisms in the Google Chrome browser. The newly discovered exploit was used in the malicious WizardOpium operation.

A zero day exploit is a cyber attack that occurs on the same day a weakness is discovered in software. At that point, it is exploited before a fix becomes available from its creator. Zero-day vulnerabilities are basically bugs in software, which leaves the doors open for cyber criminals to break into the system.
