What is a Cyber Attack?

Definition

A cyber attack is a deliberate attempt by individuals or groups to breach the information systems of individuals organizations or governments. These attacks are executed to steal alter or destroy data for malicious purposes such as theft disruption or espionage. Cyber attackers exploit vulnerabilities in systems networks or devices to gain unauthorised access leading to significant financial and operational damage. 

Historical Examples

Several notable cyber attacks have highlighted the severe impact these threats can have:

  1. WannaCry Ransomware Attack (2017): This global cyber attack affected over 200000 computers across 150 countries. The ransomware encrypted data on infected systems demanding ransom payments in Bitcoin. It particularly impacted the healthcare sector with the UK’s National Health Service (NHS) being one of the hardest-hit organisations.
  2. SolarWinds Hack (2020): In this sophisticated supply chain attack hackers inserted malicious code into updates of SolarWinds’ Orion software used by many multinational companies and government agencies. This breach allowed attackers believed to be Russian state actors to infiltrate U.S. federal agencies and Fortune 500 companies remaining undetected for months.
  3. Ukrainian Power Grid Attack (2015): This attack on Ukraine’s power grid was the first known successful cyber attack on a power grid. Hackers attributed to the Russian group Sandworm managed to shut down power to hundreds of thousands of citizens demonstrating the potential for cyber attacks to cause physical disruptions.
  4. NotPetya Malware Attack (2017): Initially appearing as ransomware NotPetya caused widespread damage globally with losses estimated at over $10 billion. Although it seemed to be financially motivated its primary aim was political targeting Ukraine and spreading to other countries as collateral damage.
