Analogy/Comparison

Think of these vulnerabilities as unlocked doors in a house. Hackers are like burglars who know about these unlocked doors and are using them to break in and steal things.


Why It Matters

These vulnerabilities can allow hackers to steal information, disrupt services, or take control of computer systems. For example, the vulnerability in Google Chrome could let a hacker run programs on your computer without your permission when you visit a malicious website.
