Gusano informtico (Spanish for “computer worm”) is a type of malware that self-replicates and spreads from computer to computer across a network. Unlike a computer virus, it does not need to attach itself to an existing program. Instead, it exploits vulnerabilities in software to spread its malicious payload. Common targets for gusanos informaticos include email systems, file-sharing networks, and social media platforms.
Gusanos informaticos can cause a variety of damage, including:
- Stealing sensitive data
- Disrupting network traffic
- Launching denial-of-service attacks
- Installing other malware, such as viruses or ransomware
One of the most famous gusanos informaticos is the Morris worm, which infected over 6,000 computers on the ARPANET in 1988. The worm was created by Robert Tappan Morris, a graduate student at Cornell University. Morris was convicted of violating the Computer Fraud and Abuse Act and sentenced to three years of probation.
Gusanos informaticos continue to be a major threat to computer networks today. In 2017, the WannaCry ransomware attack infected over 200,000 computers worldwide. The attack caused widespread disruption, including shutting down hospitals and businesses.
