What is Zero-day?
‘Zero-day’ describes newly found security issues which can be used by cybercriminals to attack your systems.
The common phrases you’ll hear regarding the term are:
Simply put, if there is a vulnerability, hackers can exploit it and then attack.
The main threat of this is the lack of defense, most businesses will have security in place to defend themselves from cyber-attacks, but an unknown vulnerability means that there are no preventative measures in place.
Are you at risk?
Zero-day vulnarabilities can affect web browsers such as Chrome or Edge, operating systems, office applications or even your new fridge.
It can happen to anyone, be it small or large businesses, people of interest, or even just people – it doesn’t have to be targeted. Anybody who is unlucky enough to have a zero-day vulnerability is at risk of attack.
The person who’ll use a zero-day exploit can vary too, the main group will be cybercriminals who look for financial gain through exploits.
Targeted attacks often have more reasoning behind them than simple financial gain. Corporations can use it for an advantage over competitors, groups that have been referred to as ‘hacktivists’ can pounce with political and/or social motivation.
To generalise, the attacker will always have malicious intent and be aiming for some sort of gain.
It may seem worrying that anyone can be targeted, but the key takeaway is that it’s preventable.
