A computer worm is a nasty little piece of malware designed to spread like wildfire through networks silently and relentlessly.
Unlike a virus that needs you to open a dodgy file or click a suspicious link a worm is self-sufficient a digital stowaway that finds its own way into your system and then reproduces itself like a digital bunny rabbit.
Think of it as a sneaky burglar who doesn’t need a key to get in; they just find a weak spot in your security system and slip right in.
Once inside they start making copies of themselves and spreading to other devices connected to your network causing all sorts of havoc.
How Worms Sneak In: Exploiting Weak Spots
Now you might be wondering how these worms get in.
They’re quite clever exploiting vulnerabilities or weaknesses in your operating system.
Think of these weaknesses like cracks in your house’s foundation; they’re waiting for the right moment to strike.
For instance a worm could exploit an outdated software version that hasn’t been patched with the latest security updates.
Or they might find a weakness in your network configuration like an open port that’s practically begging to be exploited.
The Difference Between Worms Viruses and Trojans
