A cyber attack is a malicious act that targets computer systems, networks, or devices to compromise their integrity, confidentiality, or availability.
Description
In the cybersecurity industry, a cyber attack refers to any attempt to gain unauthorized access to, disrupt, or damage computer systems or networks. These attacks can be carried out using various techniques and can target individuals, businesses, or government entities. Cyber attacks are often motivated by financial gain, political agendas, or personal grievances. Some common types of cyber attacks include malware infections, phishing scams, ransomware attacks, and denial-of-service (DoS) attacks. For instance, the 2017 WannaCry ransomware attack affected thousands of computers worldwide, encrypting files and demanding payment in Bitcoin for decryption. Another example is the 2020 SolarWinds cyber attack, where hackers compromised software updates to infiltrate numerous U.S. government agencies and corporations. These incidents highlight the importance of robust cybersecurity measures to protect sensitive data and maintain operational integrity against evolving threats.
Examples
- WannaCry ransomware attack in 2017, which affected over 200,000 computers across 150 countries.
- SolarWinds cyber attack in 2020, involving a significant supply chain breach impacting multiple U.S. federal agencies.
Additional Information
- Cyber attacks can lead to data breaches, financial loss, and reputational damage.
- Implementing strong cybersecurity practices, such as regular software updates and employee training, can mitigate the risk of cyber attacks.
