When people think about cybersecurity, the first thing that comes to mind is usually firewalls, antivirus software, or complicated IT infrastructure. But real-world breaches rarely start with a sophisticated hack. More often, they begin with something much simpler:
Trusting the wrong email.
Clicking the wrong link.
Following the wrong instruction.
Technology can be patched — human behavior can’t.
This is where the true danger lies.
1. Real Case : When Email Trust Gets Hijacked
Everything looked normal… until the money disappeared.
- Employee email account is compromised by the cybercriminal
- Compromised account used to notify the supplier’s customers of a change to the invoice payment details
- Customer transfers their payment to the cybercriminal’s account
- Cybercriminal receives the money
How one compromised email can do serious damage — not just from a tech side, but also from human and process gaps.
2. Breaking It Down: Shared Responsibility & Legal Aspects
Type of Security Issues
Not a technical issue — it’s a mix of human mistakes, weak processes, and missing controls.
1. On human side:
- Customer trusted email instructions without independent verification.
2. On process side:
- No secondary confirmation or approval workflow for financial transactions.
3. Technical gap:
- Weak authentication (no MFA)
- Poor mailbox monitoring
- Lack of anomaly alerts
3. Humans as the New Perimeter: Why People Get Targeted
Shared Responsibility
Everyone has a role.
1. Company:
- Protect corporate email accounts;
- Enforce MFA;
- Train staff;
- Maintain audit logs.
Example of Negligence:
Failed to secure or detect compromised account.
2. Customer:
- Verify payment details via alternate or verified channels.
Example of Negligence:
Trusted unverified payment instructions.
3. Email Provider:
- Provide secure infrastructure and detection tools.
Example of Negligence:
Limited liability if compromise stemmed from weak user control.
4. How Hackers Hack Humans: Social Engineering in Action
| Attack Method | How It Works | Common Example |
|---|---|---|
| Phishing / Credential Theft | Fake email or malicious link used to steal login details | “Reset your password here” |
| Pretexting | Hacker pretends to be IT support, HR, or another authority figure | “I need your OTP to fix your account” |
| Session Hijack | Attackers steal cookies or tokens to access accounts without passwords | Stay logged in without password |
| Business Email Compromise (BEC) | Criminal impersonates a colleague or boss to request payments | “Urgent wire transfer request” |
5. Insider Threats: “It All Started With One USB Drive”
- Employee finds a USB labeled “Salary Reports”.
- Out of Curiosity → plugs it into a company PC.
- Malware executes automatically.
- Spreads via internal network shares.
- Entire network compromised within hours.
Not All Insiders Are Bad — But All Can Cause Damage
| Category | Description | Example |
|---|---|---|
| Malicious | Intentionally cause harm | Disgruntled employee |
| Negligent | Mistakes, poor judgment | Clicks phishing link |
| Compromised | Account hijacked | Attacker uses real credentials |
6. Building the Human Firewall: Awareness, Habits & Culture
| Layer | Key Actions | Example Practice |
|---|---|---|
| Individual | Verify before you trust | Confirm payment changes |
| Technical | MFA, disable autorun | Prevent USB auto-execution |
| Network | Segmentation, monitoring | Limit damage spread |
| Culture | Awareness & reporting | “Report, don’t hide mistakes” |
Final Thoughts: Cybersecurity
Cybersecurity isn’t just about systems — it’s about people. Most breaches happen because trust is exploited, not because technology fails. With the right habits, verification steps, and awareness, these mistakes can be avoided.
