Review Questions

• How does malware function as a tool for cybercriminals and what are some common methods it uses to infect systems?
  • Malware functions as a critical tool for cybercriminals by exploiting vulnerabilities in software and human behavior. Common methods of infection include phishing emails that trick users into downloading malicious attachments or clicking on dangerous links. Additionally, malware can spread through unsecured networks or by disguising itself as legitimate software. Understanding these methods is vital for both prevention and response strategies against cyber threats.
• Discuss the implications of malware in the context of digital evidence collection and how it can affect investigations.
  • Malware significantly complicates digital evidence collection as it can manipulate or destroy data on infected systems. During investigations, forensic experts must ensure that they do not inadvertently trigger the malware, which could lead to data loss or further compromise of evidence. Additionally, malware can obfuscate activities by creating false trails or erasing logs, making it challenging to establish a clear timeline of events related to a cybercrime.
• Evaluate the evolving landscape of malware threats and how advancements in technology might influence future trends in cybercrime.
  • The landscape of malware threats is constantly evolving due to advancements in technology that provide new tools and methods for cybercriminals. With the rise of artificial intelligence and machine learning, malware can become more sophisticated and adaptive, allowing it to evade traditional security measures. As IoT devices proliferate, they present additional vulnerabilities that can be exploited by malware, leading to more complex attacks. Understanding these trends is crucial for developing proactive cybersecurity measures and legal frameworks to combat cybercrime effectively.
