how hacking works:

  • Gathering Information: First, the hacker begins by gathering information about the target. This phase involves identifying potential vulnerabilities, network architecture, system configurations, and potential entry points.
  • Scanning: Once the hacker has gathered information, they use various tools and techniques to scan the target system for weaknesses. This could involve port scanning, vulnerability scanning, or network mapping to identify potential points of entry.
  • Exploitation: After identifying vulnerabilities, the hacker attempts to exploit them to gain unauthorized access. This could involve exploiting software flaws, using default or weak credentials, or tricking users through social engineering techniques.
  • Gaining Access: Once a vulnerability is successfully exploited, the hacker gains access to the system or network. They may establish a persistent presence to maintain access for future exploits or data exfiltration.
  • Privilege Escalation: In some cases, hackers may seek to elevate their privileges within the system to gain administrative control. This allows them to access sensitive data, modify configurations, or execute malicious code.
  • Maintaining Persistence: To ensure continued access, hackers often employ various techniques to maintain persistence within the compromised system. This could involve installing backdoors, creating hidden user accounts, or manipulating system processes.
  • Covering Tracks: Skilled hackers aim to cover their tracks to avoid detection. They erase logs, modify timestamps, and remove any evidence of their activities to hinder forensic analysis and make it difficult for security professionals to trace their actions.
