Attackers have found a new route by exploiting a zero-day vulnerability in Google’s Android mobile operating system.

How does a zero-day exploit work?

A zero-day exploit is when hackers take advantage of a software security flaw to perform a cyberattack. And that security flaw is only known to hackers, meaning software developers have no clue to its existence and have no patch to fix it.

Why is a zero-day coveted?

A zero-day exploit is a type of attack where the attacker takes advantage of an unknown security vulnerability in the computer software or application. Zero-day attacks are highly successful because there is no patch available for the exploit, or application developers are unaware of the vulnerability.

What is the definition of a zero day exploit?

What is a Zero-Day Exploit? A “zero-day” or “0Day” in the cybersecurity biz is a vulnerability in an internet-connected device, network component or piece of software that was essentially just discovered or exposed. The whole idea is that this vulnerability has zero-days of history.

What does it mean to have a zero day vulnerability?

A zero-day vulnerability is a software vulnerability discovered by attackers before the vendor has become aware of it. Because the vendors are unaware, no patch exists for zero-day vulnerabilities, making attacks likely to succeed. A zero-day exploit is the method hackers use to attack systems with a previously unidentified vulnerability.

When does a zero day attack take place?
