Study Notes
- Calcutta Institute of Technology is affiliated to MAKAUT.
- Viruses, malware, cyber threats, and spyware are key cybersecurity topics.
Defining Viruses: Infection and Replication
- Viruses attach to executable files and spread when the infected file runs.
- Attachment describes how viruses attach to executable files or documents.
- Replication occurs as viruses copy their code into other files.
Malware: A Spectrum of Malicious Software
- Malware stands for Malicious Software.
- Malware encompasses software designed to disrupt, damage, or gain unauthorized system access.
- Viruses, worms, Trojans, ransomware, spyware, and adware are examples of malware.
- Viruses infect files and replicate.
- Worms self-replicate and spread.
- Trojans disguise themselves as legitimate software.
What is a Virus?
- Viruses are a type of malware that attaches to files or programs and spreads upon execution.
- Viruses require a host program to function and spread.
- Viruses can corrupt or delete data and slow down systems.
Virus vs. Malware
- Viruses are a type of malware that spreads through infected files, malware is any malicious software that harms devices.
- Virus spread requires user execution, while malware can spread automatically.
- Virus impact includes deleting, corrupting files, or slowing systems; malware impact varies (data theft, ransom, system damage).
Understanding Spyware
- Spyware monitors user activities without consent.
- Spyware records keystrokes, steals sensitive data, and tracks online behavior.
- Keyloggers, tracking cookies, and screen recorders are examples of spyware.
Common Spyware Tactics: Keylogging & Data Theft
- Keylogging records keystrokes.
- Data theft steals personal data.
- Surveillance monitors activity.
Notable Spyware Examples: Case Studies & Impact
- CoolWebSearch caused significant data breaches and impacted user privacy as a browser hijacker.
- Gator adware bundled spyware.
- FinFisher is government-level spyware.
Conclusion
- Malware, including viruses and spyware, poses serious cybersecurity threats.
- Viruses are specific malware requiring user intervention, while malware is a broader category.
- Understanding cyber threats is key to preventing attacks.
- Strong cybersecurity practices mitigate risks and enhance online safety.
- Staying informed, using reliable security tools and safe browsing habits are important.
