Did you know wealthy cybercriminals are using <\/span>zero-day exploits<\/b> now more than ever? Experts believe the rise is linked to the exponential growth of the multibillion-dollar <\/span>ransomware<\/span><\/a> industry.<\/span><\/p>\n

Zero-day exploits <\/b>are powerful and dangerous vulnerabilities often targeted by government-backed hackers for espionage purposes. But according to a 2021 report, financially driven (not politically motivated) cybercriminals made up one-third of all known zero-day hackers. That\u2019s a stark increase compared to previous years.<\/span><\/p>\n

There\u2019s big money in <\/span>zero-day exploits<\/b>. For instance, a <\/span>US-based company sold a robust iPhone zero-day<\/span><\/a> to the United Arab Emirates spies for a massive $1.3 million! Another firm has a standing offer of $2.5 million for an Android device <\/span>zero-day exploit<\/b>.\u00a0<\/span><\/p>\n

But <\/span>what is a zero-day exploit <\/b>exactly? Well, it\u2019s an advanced <\/span>cyberattack<\/span> technique that can have devastating consequences. Read on to find out how it works, what it targets, and how to identify and <\/span>prevent such an attack<\/span><\/a>.<\/span><\/p>\n

What is a Zero-Day Exploit?<\/b><\/h2>\n

Let\u2019s start with the fundamentals. <\/span>What is a zero-day exploit vs. attack <\/b>vs. vulnerability?\u00a0<\/span><\/p>\n
