How Worms Work
Worms operate by scanning networks for vulnerable systems. Once a vulnerability is found, the worm exploits it to copy itself to the new system. This process continues automatically, allowing the worm to spread rapidly. — Justin Chambers: Best Movies & TV Shows Ranked
Key Characteristics:
- Self-Replicating: Worms can copy themselves without human intervention.
- Network-Based: They spread through networks, often exploiting security flaws.
- Autonomous: They don't need to attach to a host program.

- Morris Worm (1988): One of the earliest and most infamous worms, it exploited vulnerabilities in Unix systems.
- SQL Slammer (2003): Caused widespread internet slowdown by exploiting a flaw in Microsoft SQL Server.
- Stuxnet (2010): A sophisticated worm that targeted industrial control systems, particularly those used in Iran's nuclear program.
How to Protect Against Worms
- Keep Software Updated: Regularly update your operating systems and applications to patch security vulnerabilities.
- Use Firewalls: Firewalls can help block unauthorized access to your network.
- Install Antivirus Software: Antivirus software can detect and remove worms.
- Be Cautious with Email Attachments: Avoid opening suspicious email attachments or clicking on unknown links.
