Training Employees to Defend Against Human-Targeted Cyber Threats

Cybersecurity goes beyond firewalls and encryption—employees serve as the first line of defense against human-targeted threats like phishing, social engineering, and insider attacks. Effective training and awareness programs can greatly reduce an organization’s risk exposure.

Read on to discover how you can protect your organization by equipping your workforce to identify and counter human-targeted cyber threats.

Understanding Human-Targeted Cyber Threats

1. Phishing Attacks

Phishing emails or messages trick employees into providing sensitive information or clicking on malicious links. Variants include:

• Spear phishing (targeted attacks)
• Whaling (targeting executives)
• Vishing (voice phishing)
• Smishing (SMS phishing)

2. Telecom Cyber Threats

If you believe that telephones are inherently secure, think again. Cybercriminals frequently exploit phone communications to deceive employees into divulging sensitive information or clicking on malicious links. In more severe cases, attackers may gain access to telecommunication networks, allowing them to reroute, intercept, or manipulate calls.

Common variants of these attacks include:

• Vishing (Voice Phishing): Attackers impersonate trusted entities over the phone to extract sensitive information, such as login credentials or financial details.
• Caller ID Spoofing: Hackers disguise their phone number to appear as a legitimate entity, increasing the likelihood of deception.
• SIM Swapping: Criminals convince a mobile carrier to transfer a victim’s phone number to a new SIM card, allowing them to intercept calls, messages, and multi-factor authentication codes.
• Rogue Base Stations (IMSI Catchers): Attackers use fake cell towers to intercept mobile calls, messages, and location data.
• VoIP Hacking: Cybercriminals exploit vulnerabilities in VoIP systems to eavesdrop on calls, inject malicious commands, or conduct toll fraud.
• Call Forwarding Attacks: Hackers manipulate call forwarding settings to reroute calls to their own numbers, allowing them to impersonate victims or intercept sensitive conversations.
• Robocalls & Social Engineering: Automated calls attempt to trick recipients into providing information, transferring funds, or installing malware via callback requests.

3. Social Engineering

Though we mentioned earlier, we have to talk about social engineering.

If you wondered how can someone engineer society well the following happens:
Cybercriminals manipulate employees into divulging confidential data by exploiting trust, authority, or urgency. Examples include:

• Pretexting: Impersonating someone trustworthy
• Baiting: Luring victims with free software or rewards
• Tailgating: Gaining physical access by following authorized personnel

One of the key tools of social engineering is intelligence gathering. The more information attackers have about you, the easier it is for them to manipulate you. This is why it is crucial to avoid publicly sharing sensitive information—or even indirect connections to it. With just a click, various tools can compile detailed profiles on individuals.

By the time a hacker contacts a victim within your organization, they often already possess a detailed graph or table outlining all the necessary information for deception. This may include details about colleagues, superiors, email addresses, and personal information.

Of course, you don't have to be paranoid, but not posting your entire organization structure to LinkedIn helps a lot here.:)

4. Insider Threats

Malicious or careless insiders can compromise security by leaking data, misusing credentials, or inadvertently enabling attacks.

Here, proper organizational controling, monitoring and policies are crucial. It is also advisable to have a clear policy on what is allowed and what is not, and to have a clear policy on what happens if someone breaks the rules.

Insights from the ENISA Threat Landscape 2024 Report

The European Union Agency for Cybersecurity (ENISA) highlights social engineering, particularly phishing, as a major threat in its Threat Landscape 2024 report. This emphasizes the urgent need for strong employee training programs within organizations to reduce these risks.

The Role of Employee Training in Cybersecurity

Reducing the Risks of Ransomware Attacks

Although the ENISA report noted efforts to disrupt ransomware infrastructure, ransomware attacks continue to rise and pose a significant threat. These attacks often depend on user actions, such as opening a file or clicking a link. Educating employees to identify suspicious emails and attachments can be an effective measure in preventing ransomware infections.

Addressing Credential Compromise

Phishing, as an initial attack vector, poses a significant risk of credential compromise. Fraudulent forms and websites can easily deceive employees into disclosing their login information. By educating employees to recognize phishing attempts, organizations can reduce the risk of credential theft and defend against one of the most potent attack vectors today.

AI and Social Engineering

With the rise of AI, the threat of AI-generated deepfakes and synthetic media is also growing. These technologies can be used to craft highly convincing social engineering attacks.

Attackers can exploit this technology to:

• Create fake audio or video messages from executives.
• Generate realistic chatbots to impersonate employees.
• Develop convincing phishing emails using AI-generated text.
• Generate fake audio on live calls to impersonate trusted individuals.

Training employees to verify the authenticity of messages and media can help prevent them from falling victim to such attacks. Implementing security measures, such as strict policies and verification mechanisms, can further enhance protection against these threats.

Conclusion

The ENISA report provides clear evidence that human error is a major contributor to cybersecurity breaches. With the rise of ransomware and credential-based attacks, organizations must prioritize employee training to bolster their cybersecurity defenses. Investing in comprehensive training programs can significantly mitigate risks, improve incident response capabilities, and safeguard sensitive business assets from cyber threats.

Best Practices for Employee Cybersecurity Training

Ok, now that we talked about the threats, and made you all worried, let's talk about how to protect your organization.

1. Conduct Regular Security Awareness Training

Continuously educate employees on the latest cyber threats and safe online practices. Tailor sessions to different roles, use real-world examples, and reinforce the importance of vigilance.

• Use real-world case studies to illustrate common threats.
• Provide interactive simulations, such as phishing tests.
• Offer role-specific training tailored to different departments.

2. Implement a Strong Reporting Culture

Encourage all staff to promptly report suspicious emails, messages, or incidents. Provide clear, accessible reporting channels and recognize those who actively contribute to maintaining security.

• Encourage employees to report suspicious emails, messages, or activities.
• Ensure clear, simple reporting mechanisms.
• Reward employees for proactive security vigilance.

3. Enforce Multi-Factor Authentication (MFA)

Require additional verification steps—beyond just a password—for accessing critical systems. Prioritize app-based or hardware token methods to strengthen protection against unauthorized access.

• Require MFA for all critical systems and applications.
• Educate employees on using authentication apps over SMS-based codes.

4. Limit Data and Access Privileges

Adopt the “Least Privilege” approach so users only have the access they need. Regularly review and adjust permissions, ensuring outdated or unnecessary accounts are removed.

• Follow the principle of least privilege (PoLP) to restrict unnecessary access.
• Implement role-based access control (RBAC).
• Regularly audit permissions and revoke unused accounts.

5. Encourage Strong Password Practices

Promote the use of password managers and enforce policies for creating and rotating complex passwords. Educate employees on the importance of unique, robust credentials to safeguard accounts.

• Use password managers to generate and store complex passwords.
• Implement corporate policies on password rotation and uniqueness.
• Educate on avoiding password reuse across personal and work accounts.

6. Simulate Attack Scenarios

Conduct regular drills and phishing simulations to measure and improve security readiness. Engage leadership in tabletop exercises to test and refine incident response plans.

• Run periodic phishing simulation campaigns to test employee awareness.
• Conduct tabletop exercises for handling security incidents.
• Involve leadership in cyber crisis drills.

The Role of Leadership in Cybersecurity Awareness

Leaders set the tone for a secure, resilient organization. Their commitment to cybersecurity is reflected in their active participation, clear communication of policies, and strategic resource allocation, all of which foster a culture where security is everyone's responsibility.
