The company continued and explained the fact that “An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.”

Thomas Dullien who is Google Project Zero’s researcher was the one who found out that cyber attackers are able to trigger a memory-corruption problem in the engine if the make Windows Defender and other security software scan a specifically developed file.

There are various ways in which attackers can act

According to Microsoft, attackers can act in multiple ways to achieve the result. For instance, they can place the file on a particular website, in an instant message or an email. They can also put it in a shared directory.
