The tech world is as much scary as it is exciting owing to the fact that a minor mistake leads upto big disasters. This seemingly scary statement can be hinged to the instance of a Zero Day. A Zero day has it’s origin back to the times when piracy of content was still rife. Any movie that is imminent if get a piracy release then it is called a Zero Day.
Now, fast forward to the recent times, with a lot of development in the software, uncertainty 50k pegasuszetter zeroday, hardware, firmware and other cyber entities, Zero day has come to cover the malicious attacks on little gap holes that a developer or even consumer may not be even aware of. These little gaps which are vulnerable to such attacks have to come to known as the Zero Day Vulnerablity and the intnet to exploit such vulnerabilities have come to know as the Zero Day Exploit. In this article, we will try to understand these two technical terms that come under the facet of Zero Day Attack.
Zero Day Vulnerability vs Zero Day Exploit
A software product that has been programmed to exploit a known zero-day vulnerability is known as a zero-day exploit. A zero-day exploit is typically disguised as malware. Until they are publicly known and either the software is patched or other security measures are implemented to successfully identify and stop the exploit, zero-day exploits are frequently quite successful.
How Zero day attacks or Exploits work
One thing that we all should know is that no amount of diligence can actually ensure perfection in the tech world. When a cybercriminal discovers that weakness, they can create a piece of code to exploit it. It will depend on the kind of vulnerability they’ve found what that code is and accomplishes.
Cyber attackers frequently accomplish this through social engineering techniques, which prey on people’s psychology to get them to lower their defences. A classic example of social engineering is the use of threatening messages in phishing scams to convince victims to act in a certain way.
Some of the most common example of Zero Day attacks that exploit Zero Day Vulnerability
Sony Zero Day Attack
In late 2014, a zero-day exploit affected the Sony Pictures. The attack was a brutual threat to sony’s network that resulted in an illicit file sharing among various third party websites that were supposed to remain confidential. Information on upcoming films, commercial strategies, and the private email accounts of top Sony executives were among the hacked material.
Google Chrome Zero Day Attack
Google’s Chrome browser was discovered to be susceptible to a number of zero-day attacks in December 2021. Google rapidly released patches, but it kept quiet about the specifics of the flaws it discovered. That was done to stop them from being further abused before users could update. Nevertheless, it was discovered that the flaw came from the V8 JavaScript engine that the Chrome browser uses.
