Outbound Email Security Threat
Prevent Intentional Confidential Information Leakage
What is Intentional Information Leakage?
Intentional Information Leakage refers to the deliberate act of disclosing sensitive or confidential information through email to external parties or illegally exposing it. This act often includes internal information leaks within an organization, disclosure of confidential documents, leakage of personal information, and intentional exposure of information for financial gain, among other possibilities.
Email-based information leakage can take various forms, and here are some examples:
- Insider Information Leakage: This is when insiders within an organization intentionally leak internal information or plans of the organization.
- Disclosure of Confidential Documents: This occurs when individuals within an organization or external attackers intentionally leak an organization’s confidential documents or secret information through email.
- Personal Data Breach: It involves organizations handling personal information in violation of data protection laws, leading to the leakage of personal information.
Intentional Pathways of Information Leakage
Access to Sensitive Information
The process begins with an individual, often an insider within an organization, gaining unauthorized access to sensitive or confidential information. This information could include confidential documents, financial data, or personal information.
Email Composition
The individual then composes an email that contains the sensitive information they intend to leak. They may use a personal or fake email account to send the message, making it harder to trace back to them.
Recipient Selection
The sender chooses the recipient(s) of the email. In some cases, they may target external parties, competitors, or entities willing to pay for the information. Alternatively, they might leak information to harm the organization or individuals within it.
Information Sharing
The sender attaches the sensitive documents or information to the email or includes it in the email body. They might use various techniques to obfuscate the content, such as encoding or encryption, to avoid immediate detection.
Sending the Email
The email is sent from the sender’s chosen email account to the recipient(s). This step may involve using techniques to anonymize or hide the sender’s identity.
Covering Tracks
After sending the email, the sender may take additional steps to cover their tracks, such as deleting any traces of the sent email from their own email account or modifying email headers to mislead investigators.
