Google Detected 11 Zero-Day Vulnerabilities in H1 2020

Recently, Google Project Zero released the list of vulnerabilities exploited in 2019. Along with the first “Year In Review” report, Google also mentioned the zero-day vulnerabilities they’ve come along in the first half of 2020.
According to Google Project Zero’s security team, 11 zero-day vulnerabilities have been tracked in the first half of 2020. This takes 2020 on the track to have just as many zero-days as traced in the last year. Experts say that it may surpass the figure of 20 of 2019.

Google Project Zero

Google traced down a number of flaws in its applications used by millions of users, which could be exploited by cybercriminals. After tons of vulnerabilities were found, Google decided to form a team completely dedicated to finding flaws, not only in Google utilities but also in other applications. The new project was devised on 15 July 2014 named the GOOGLE PROJECT ZERO, on Google security blog.
MixMode Zero Day Attacks 01
The team employed by Google finds zero-day vulnerabilities. After these bugs are found, the Project Zero experts report it to the developer and make it public once the patch is released, or if 90 days pass without the patch being released. Along with the zero-day bugs, Project Zero team also illustrated how attackers exploit the bugs. This makes developers and users aware of the potential threats and their mitigations.

Zero-Day Vulnerability

A latest learned vulnerability is referred to as a zero-day vulnerability (or 0-day vulnerability). It also means that a fix or update of the bug is not yet released from the developer and the developer of the target application has zero days to protect its users.
But if the vendor fails to release a patch for the bug and hackers have managed to exploit the vulnerability, that is known as a zero-day attack.

Proactive Measures

  • Always keep your system equipped with genuine antivirus software. It will work as the first line of defence.
  • In today’s time, everyday new malware infection is detected in the wild, even making your antivirus susceptible to newly updated threats. That’s why it is always important to always keep your antivirus up to date.
  • Check for a zero-day vulnerability patch online once the bug is announced. Usually, developers work quickly to work on their zero-days to protect their users.
Always follow cyber ethics and establish safe and protective online habits.
