Phases of a Data Breach

Initial Access

Data breaches often begin with initial access. Attackers seek entry points to infiltrate a network. These entry points can include weak passwords or unsecured devices. Attackers may also exploit vulnerabilities in software. Once inside, attackers aim to exploit the system.

Entry Points

Entry points serve as gateways for attackers. Weak passwords provide easy access. Unsecured devices connected to a network pose risks. Attackers may use phishing emails to trick users. These emails appear legitimate but contain malicious links. Clicking on these links grants attackers access to a network.

Exploitation

Exploitation occurs after gaining entry. Attackers leverage vulnerabilities to escalate privileges. This process allows attackers to move freely within a network. Attackers may install malware to maintain access. Exploitation enables attackers to gather sensitive information. The goal is to prepare for data exfiltration.

Data Exfiltration

Data exfiltration involves the transfer of stolen information. Attackers use various methods to extract data. The process often goes unnoticed by the organization. Detecting exfiltration requires monitoring for indicators of compromise.

Methods Used

Attackers employ different methods for data exfiltration. Email serves as a common tool for sending stolen data. Attackers may use encrypted channels to avoid detection. Social engineering tricks users into sharing sensitive information. Network traffic analysis helps identify unusual data transfers. Attackers often target databases containing valuable information.

Indicators of Compromise

Indicators of compromise signal potential breaches. Unusual network activity raises red flags. A sudden increase in outbound traffic suggests data exfiltration. Unauthorized access attempts indicate a breach. Monitoring email logs can reveal suspicious communications. Changes in file permissions may point to insider threats. Organizations must remain vigilant to detect these signs early.
