6.1 Introduction: why study the attacker perspective
This section focuses on introduction: why study the attacker perspective from the attacker perspective. Public details can make a fake request sound specific and credible.
The defensive habit is to reduce unnecessary exposure and review what documents, profiles, photos, roles and contact details reveal before someone else combines them.
Many attacks start before the first message is sent. Public information, social profiles, documents, roles and habits help attackers build credible stories. This module teaches how to look at public traces with the attacker perspective and reduce unnecessary exposure.
6.1.1 Attackers often look for the easiest path
This detail focuses on attackers often look for the easiest path from the attacker perspective. Public details can make a fake request sound specific and credible.
The defensive habit is to reduce unnecessary exposure and review what documents, profiles, photos, roles and contact details reveal before someone else combines them.
OSINT is not magic
OSINT is not magic: it is careful reading of public traces. Reducing unnecessary exposure makes social engineering harder.
6.1.2 Introductory example: a credible fake request
This detail focuses on introductory example: a credible fake request as a form of deception built around context, pressure and a requested action.
The safest response is to read the request as a whole: sender, channel, timing, link, attachment, payment instruction, code request and independent verification path.
6.2 What OSINT is
This section focuses on what osint is from the attacker perspective. Public details can make a fake request sound specific and credible.
The defensive habit is to reduce unnecessary exposure and review what documents, profiles, photos, roles and contact details reveal before someone else combines them.
6.2.1 Legitimate and malicious use of OSINT
This detail focuses on legitimate and malicious use of osint from the attacker perspective. Public details can make a fake request sound specific and credible.
The defensive habit is to reduce unnecessary exposure and review what documents, profiles, photos, roles and contact details reveal before someone else combines them.
6.2.2 What information an attacker may look for about a person

The useful habit is to connect details instead of checking them in isolation. Context, channel, timing, destination and consequences provide a clearer picture of risk.
6.2.8 Exposed emails and generic inboxes
This detail focuses on exposed emails and generic inboxes in practical terms: what is being requested, what data or access is involved and what could go wrong if the action is rushed.
The useful habit is to connect details instead of checking them in isolation. Context, channel, timing, destination and consequences provide a clearer picture of risk.
6.2.9 Leaked data and old accounts
This detail focuses on leaked data and old accounts from the attacker perspective. Public details can make a fake request sound specific and credible.
The defensive habit is to reduce unnecessary exposure and review what documents, profiles, photos, roles and contact details reveal before someone else combines them.
6.3 How collected information becomes an attack
This section focuses on how collected information becomes an attack as a form of deception built around context, pressure and a requested action.
The safest response is to read the request as a whole: sender, channel, timing, link, attachment, payment instruction, code request and independent verification path.
6.3.1 Reducing personal exposure
This detail focuses on reducing personal exposure from the attacker perspective. Public details can make a fake request sound specific and credible.
The defensive habit is to reduce unnecessary exposure and review what documents, profiles, photos, roles and contact details reveal before someone else combines them.

The defensive habit is to reduce unnecessary exposure and review what documents, profiles, photos, roles and contact details reveal before someone else combines them.
6.4 Practical procedure: personal exposure check
This section focuses on practical procedure: personal exposure check from the attacker perspective. Public details can make a fake request sound specific and credible.

6.4.1 Practical procedure: business exposure check
This detail focuses on practical procedure: business exposure check from the attacker perspective. Public details can make a fake request sound specific and credible.
The defensive habit is to reduce unnecessary exposure and review what documents, profiles, photos, roles and contact details reveal before someone else combines them.
6.4.2 Checklist: before publishing personal content
This detail turns the topic into a practical checklist. The goal is to make the safe action easy to repeat when the situation appears in real life.

6.4.3 Checklist: before publishing business content
This detail turns the topic into a practical checklist. The goal is to make the safe action easy to repeat when the situation appears in real life.

A convincing scam often uses real information found in public sources.
Publishing roles, absences, documents or procedures without thinking about how they could be abused.
Review what is public before an attacker does.
Public exposure scenario
Use a fictitious profile or organization and list which public details could help build a scam message.
OSINT is not magic: it is careful reading of public traces. Reducing unnecessary exposure makes social engineering harder.
