Final answer:
A cyber attack involves a deliberate attempt to compromise computer systems or networks. Examples of politically motivated cyber attacks since 2007 include Stuxnet and NotPetya.
Step-by-step explanation:
A cyber attack refers to a deliberate and malicious attempt to compromise the security of computer systems, networks, or devices, usually with the intent to disrupt, steal information, or cause damage. Hackers use various tactics such as phishing, malware, or exploiting vulnerabilities to gain unauthorized access. They can steal sensitive data, disrupt services, or even take control of systems.
Two examples of politically motivated cyber attacks since 2007 are:
- Stuxnet: This was a highly sophisticated cyber weapon discovered in 2010 that targeted Iran's nuclear facilities. It was believed to be jointly developed by the United States and Israel. Stuxnet sought to sabotage Iran's uranium enrichment program by causing physical damage to industrial control systems.
- NotPetya: NotPetya, discovered in 2017, was a ransomware attack that primarily affected Ukraine but had global repercussions. It targeted multiple sectors, including government organizations and businesses. Many experts attribute this cyber attack to state-sponsored actors from Russia.
