Why this module exists. Initial access — getting first execution in a target environment — has evolved as defences have improved. Spear-phishing still works but with refined techniques. Cloud-credential abuse is rising. This module covers the 2026 initial-access landscape and the operator’s modern toolkit.

The initial-access categories

  • Phishing: targeted email with malicious link or attachment.
  • Valid accounts: stolen / purchased credentials; password spray.
  • Exposed services: VPN, RDP, web-app vulnerabilities.
  • Supply chain: compromise a vendor; reach the target.
  • Drive-by compromise: malicious website; user visits and is compromised.
  • Removable media: USB drops, infected media.
