What is cyber attack?
A cyber attack is the targeted exploitation of computer systems, technology-dependent companies and networks. Cyber attacks use malicious code to alter computer code, logic, or data, resulting in devastating consequences that put data at risk and lead to cybercrime, such as theft of information and identities.
Cyber attack is also known as a Computer Network Attack (CNA).
Cyber attacks can have the following consequences:
- Identity theft, fraud, extortion
- malware, pharming, phishing, spamming, Spoofing, Spyware, Trojans and Viruses
- Stolen hardware, such as laptops or mobile devices
- Denial of service and distributed denial of service attacks
- violation of access
- Password sniffing
- system infiltration
- Website defacement
- Private and public web browser exploits
- Instant messaging abuse
- Intellectual property (IP) theft or unauthorized access
The Institute of Security Technology Studies at Dartmouth University researches and examines cyber attack problems law enforcement investigations face and focuses on the continuous development of IP tracing, data analysis, real-time surveillance and national data sharing.
