In the modern digital landscape, cyber attacks have become increasingly common and impactful for both individuals and organizations. These attacks can take various forms, including malware, ransomware, phishing, and social engineering, among others. The potential consequences range from financial loss to damage to a company’s reputation and even loss of life in some cases. This article sheds light on the anatomy of cyber attacks, using real-life examples and lessons to help us better protect ourselves.

The Stages of a Cyber Attack

  • Reconnaissance: The attacker collects information about their target to identify potential vulnerabilities and plan their attack.
  • Gaining Access: The attacker exploits a vulnerability in the target’s network or system to gain control over it.
  • Escalating Privileges: With control, the attacker may steal user credentials, misconfigure security settings, or use malware to further gain control over the target’s systems and data.
  • Carrying Out Objectives: The attacker may now steal sensitive data, install malware, or disrupt services.
  • Covering Tracks: To avoid detection, the attacker may delete logs or modify system settings to make it harder for defenders to identify the attack.

Real-life Examples of Cyber Attacks

  • WannaCry Ransomware Attack (2017): Affected more than 200,000 computers across 150 countries, encrypting files and demanding a ransom in exchange for the decryption key.
  • Target Data Breach (2013): Compromised the personal and financial information of over 110 million customers.
  • Sony Pictures Hack (2014): North Korean operatives stole and released sensitive information, including unreleased movies and confidential employee data.
