Google has released an emergency security update for the Chrome desktop web browser. The update fixes the seventh zero-day vulnerability that has been this year. The vulnerability could have allowed attackers to read sensitive app data. Let’s take a detailed look at this zero-day exploit!
What is a Zero-Day?
A zero-day includes the vulnerability, exploit and attack. The vulnerability is a software vulnerability discovered by attackers before the developer has become aware of it. Because the developers are unaware, no patch exists for zero-day vulnerabilities, making attacks likely to succeed.
Whereas, the zero-day exploit is the method hackers use to attack systems with a previously unidentified vulnerability. The zero-day attack is the actual use of a zero-day exploit to cause damage to or steal data from a system affected by a vulnerability.
