Social engineering has quickly become one of the most concerning threats to businesses. While many business owners focus on protecting systems with technical cybersecurity defences, social engineering takes a different approach, targeting the human element within organisations.
Social engineering attacks leverage psychological manipulation to trick individuals into divulging sensitive information or performing actions that compromise security.
In this blog, we’ll explore what social engineering is, the risks it presents to businesses, common attack types, and, most importantly, how business owners can protect against these tactics.
What is Social Engineering? The Basics for Businesses
Social engineering is a technique where cyber attackers manipulate individuals psychologically to bypass security protocols and obtain sensitive information or unauthorised access. These tactics exploit human emotions like trust, curiosity, and fear, rather than relying on technical hacking methods.
Why Social Engineering Threatens Businesses
- Human vulnerability: Cybersecurity training is effective, however the advancements of cyber criminals can still make employees the weak link in security.
- Valuable business information: Businesses possess financial records, customer data, and proprietary information, all of which are attractive to cyber attackers.
- Financial and reputational stakes: For businesses, a successful social engineering attack can mean financial loss, ongoing legal complications, and damage to customer trust.
Businesses are frequently targeted because social engineering attacks are easy to execute, difficult to trace, and can result in significant rewards for attackers. Therefore, understanding social engineering and implementing robust protections against it is essential for businesses.
Types of Social Engineering Attacks That Target Businesses
Different forms of social engineering attacks target organisations in unique ways. Here’s a look at some of the most prevalent types:
1. Phishing
Phishing attacks are among the most common and involve attackers posing as legitimate entities to extract sensitive information.
- Email phishing: Often, attackers send emails impersonating banks, suppliers, or colleagues to encourage individuals to click malicious links.
- SMS phishing (Smishing): Fake text messages urging recipients to click on a link to resolve an “urgent” issue, such as account verification.
- Voice phishing (Vishing): Attackers impersonate customer service representatives over the phone to extract information or transfer funds.
Example: A business receives an email from an “accounting department” requesting an urgent invoice payment. However, the link directs the user to a cloned site, capturing login credentials.
2. Pretexting
In pretexting, attackers create a false pretext or story to gain access to information.
- Attackers pose as internal personnel, for instance HR, to get sensitive information, such as passwords or account details.
- The attacker builds credibility by using background information obtained from social media or other open sources.
Example: An attacker impersonates an HR executive and contacts an employee, requesting their login credentials for “system maintenance.”
3. Baiting
Baiting lures victims with a promise of something attractive, such as a free gadget or special deal.
- Digital baiting: Attackers offer free software downloads that contain malware.
- Physical baiting: A USB stick labelled “Employee Salaries” is left in an office area, enticing someone to plug it in out of curiosity.
Example: An employee finds a USB labelled “Confidential Client Data” in the parking lot, and upon connecting it to a computer, inadvertently installs malware.
4. Tailgating and Piggybacking
These tactics involve physical infiltration, where attackers gain access to secure business premises by following closely behind authorised personnel.
- Tailgating: An attacker “accidentally” forgets their access card and relies on an employee to hold the door.
- Piggybacking: Attackers openly request someone to let them in, often by pretending they’re new to the premises.
Example: A person dressed as a delivery driver follows an employee into a building, eventually accessing secure areas without detection.
5. Spear Phishing and Whaling
These are targeted versions of phishing, focusing on high-profile individuals or specific departments.
- Spear Phishing: Attacks tailored to individuals or departments, based on extensive research.
- Whaling: Attacks targeting high-level executives or decision-makers, often involving requests for large transactions or sensitive information.
Example: An employee receives a request from a “CEO” to transfer funds urgently. Due to the email’s specificity and tone, it appears legitimate, prompting the employee to authorise the transfer.
The Business Impact of Social Engineering Attacks
Social engineering attacks can have serious consequences for businesses. Here’s what’s at stake:
1. Financial Loss
- Direct financial losses from fraudulent transactions.
- Increased costs from the process that following involved with resolving security breaches and implementing additional security measures.
2. Data Breaches and Confidentiality Risks
- Exposure of sensitive customer and employee data can lead to lawsuits and penalties.
- Loss of proprietary or sensitive information can compromise competitive advantage.
3. Reputational Damage
- Customers lose trust in businesses that fail to protect their data.
- Damaged reputation can result in lost clients and reduced revenue.
4. Operational Disruptions
- Social engineering attacks may force companies to shut down systems to contain damage.
- Disrupted operations and client dissatisfaction can further impact revenue.
Real-World Examples
In 2021, Service NSW experienced a major breach due to a phishing attack, resulting in sensitive data exposure. Such cases highlight the need for heightened vigilance and robust defences.
How to Protect Your Business Against Social Engineering
Securing your business against social engineering requires a multi-layered approach. Here are steps business owners can implement to strengthen defences:
1. Train Employees Regularly
Training is key in helping employees recognise and respond to social engineering attempts.
- Regular cybersecurity training sessions to cover the latest tactics and threats.
- Simulated phishing attacks to gauge employee response and identify areas for improvement.
- Encouraging awareness of unexpected emails, messages, or phone calls and verifying unknown requests before responding.

2. Implement Verification Protocols
Having strict verification protocols makes it harder for social engineers to succeed.
- Verify all requests for sensitive information, especially those coming via email or phone.
- Use multi-step verification for large transactions or sensitive data access.
- Encourage a culture of “verify before trust” within a business, so employees feel comfortable questioning unusual requests.
3. Use Multi-Factor Authentication (MFA)
Multi-Factor Authentication (MFA) significantly enhances security by requiring additional verification steps.
- Implement MFA for all employees, particularly for accessing sensitive systems or data.
- Consider biometric verification for extra-sensitive areas, such as financial accounts or executive logins.
- Encourage MFA adoption on personal devices and email accounts used for business purposes.
4. Limit Access to Sensitive Information
Restricting data access based on roles can prevent unauthorised exposure.
- Apply the principle of least privilege: Only allow access to information necessary for each role.
- Regularly review access permissions to ensure they align with current roles and responsibilities.
- Limit administrative access to a few trusted personnel to reduce vulnerability.
5. Conduct Regular Security Audits
Security audits help identify potential vulnerabilities in your IT defences.
- Annual or semi-annual audits of security practices to spot weaknesses in employee protocols or technical systems.
- Engage external cybersecurity experts for an unbiased perspective and recommendations.
- Adjust protocols based on audit results to keep up with emerging threats.
6. Promote a Culture of Caution
Building a cautious, security-conscious culture can make a big difference.
- Encourage employees to report suspicious activity without fear of repercussions.
- Regular reminders and updates about new social engineering tactics help keep everyone informed.
- Empower employees to question unusual requests and make it a standard part of workplace interactions.
Real-World Examples: High-Profile Social Engineering Attacks
Social engineering has proven successful even against some of the world’s most secure organisations. Here are examples that illustrate its impact:
- 2013 Target Breach: Attackers accessed sensitive customer data through a third-party vendor’s compromised credentials. A simple phishing attack led to significant data exposure and financial loss.
- Twitter Hack 2020: Spear phishing of Twitter employees allowed attackers to access high-profile accounts, including those of political figures and CEOs, to promote a cryptocurrency scam.
- Australian Health Insurer Attack: A phishing email led to a large-scale data breach in 2021, compromising customer data and causing severe reputational damage.
These examples underscore the importance of vigilance, training, and layered security.
Future Trends in Social Engineering and the Evolving Threat Landscape
Social engineering is evolving to adapt to new environments and exploit emerging technologies. Here are some trends to watch:
- AI-Powered Phishing: Attackers are using AI to create realistic emails and messages, making phishing attempts more difficult to detect.
- Exploitation of Remote Work Vulnerabilities: With remote work increasingly common, attackers target employees working from less secure environments.
- Increased Social Media Scraping: Social engineers gather personal information from social media to tailor their attacks, especially for spear phishing.
To stay protected, businesses need to regularly update security measures and educate employees on the latest social engineering trends.
