Hyökkäysprosessi

Hyökkäysprosessi refers to the systematic steps an attacker takes to compromise a target system or network. This process is often broken down into distinct phases, though the exact terminology can vary. The initial phase typically involves reconnaissance, where the attacker gathers information about the target, looking for vulnerabilities, potential entry points, and valuable data. This can include passive methods like searching public records or active methods like port scanning.

Following reconnaissance, the attacker moves to weaponization, where they create or select malicious tools or payloads designed to exploit the identified vulnerabilities. This might involve crafting malware, developing exploit code, or preparing phishing emails. The next phase is delivery, where the weaponized payload is sent to the target. This can occur through various channels such as email attachments, infected websites, or compromised removable media.

Once the payload is delivered, the attacker aims for exploitation. This is the phase where the malicious code is executed, and the vulnerability is actively leveraged to gain unauthorized access or control. After successful exploitation, the attacker may establish persistence, ensuring continued access to the compromised system even if it is rebooted or the initial exploit is patched. This can involve installing backdoors or creating new user accounts.

The final stages often involve command and control, where the attacker communicates with the compromised system to issue further instructions or exfiltrate data, and actions on objectives, where the attacker achieves their ultimate goal, which could range from data theft and financial fraud to system disruption or espionage. Understanding these phases is crucial for developing effective defense strategies.
