When Cyber Criminals Target the Most Vulnerable

Cyber criminals do not always attack the biggest organisation or the business with the most valuable technology.

Often, they target whoever appears easiest to exploit.

That may be a small company with limited IT resources, an employee under pressure, an older person unfamiliar with online threats, a new starter who does not yet understand company procedures or an organisation relying on outdated systems.

Attackers look for moments of weakness, confusion and urgency. They know that people are more likely to make mistakes when they are busy, worried or unsure about what to do.

Understanding who may be most vulnerable—and why—is an important part of protecting your employees, customers and wider organisation.

Cyber Criminals Look for Opportunity

Many cyber attacks are not personally targeted at first.

Criminals often use automated tools to send thousands of phishing emails, test stolen passwords or scan the internet for vulnerable systems.

Once they find a potential weakness, they may focus their attention on that person or organisation.

Attackers may look for:

• Employees with access to payments or confidential information
• Businesses using unsupported software
• People who are unfamiliar with technology
• Organisations without multi-factor authentication
• New employees who do not yet know internal processes
• Staff working remotely or under pressure
• Companies experiencing rapid change or disruption
• Individuals who publicly share personal or business information

Cyber crime is frequently opportunistic. A business does not need to be famous or wealthy to become a target.

Why Smaller Businesses Can Be Vulnerable

Small and medium-sized businesses may believe that cyber criminals are more interested in large corporations.

In reality, SMEs can be attractive because they often hold valuable information while having fewer internal security resources.

A smaller business may have:

• Limited cyber security expertise
• Older devices or applications
• Less formal payment procedures
• Fewer people monitoring alerts
• Shared user accounts
• Weak backup arrangements
• Inconsistent employee training
• Greater dependence on one IT supplier or key system

Attackers know that disruption can place significant pressure on a smaller organisation.

If systems are unavailable, the business may struggle to operate, invoice customers or communicate with suppliers. This pressure can make an SME more likely to respond to an extortion demand or fraudulent request.

New Employees

New starters are common social engineering targets.

They may not yet know:

• Who is authorised to request payments
• How senior managers normally communicate
• Which suppliers the business uses
• How suspicious emails should be reported
• What information can be shared
• Which IT requests are legitimate

An attacker may impersonate a director or colleague and rely on the employee’s desire to be helpful.

For example, a new employee could receive an urgent message requesting gift cards, confidential documents or account credentials.

New-starter security training should therefore take place before access to sensitive systems is granted.

Finance Teams

Finance employees are particularly valuable targets because they can authorise payments and access banking information.

Cyber criminals may impersonate:

• Managing directors
• Suppliers
• Customers
• Banks
• Payroll providers
• Accountants

The attacker may request an urgent bank transfer, invoice payment or change to supplier details.

These messages often create pressure by claiming that the matter is confidential or time-sensitive.

Strong payment procedures should ensure that unusual requests are independently verified, regardless of who appears to have sent them.

Senior Leaders

Directors and senior managers are also targeted because they usually have extensive access and authority.

An attacker who compromises a senior employee’s mailbox may be able to:

• Read confidential conversations
• Impersonate the individual
• Approve fraudulent requests
• Target other employees
• Access business documents
• Reset passwords for other services

Executives may also be more exposed publicly through company websites, social media and industry events.

This information can help criminals create convincing and personalised attacks.

Senior staff should receive the same security training as everyone else, along with additional protection appropriate to their level of access.

Employees Under Pressure

People are more likely to make mistakes when they are:

• Busy
• Tired
• Distracted
• Working to a deadline
• Dealing with several tasks
• Working outside normal hours
• Concerned about disappointing a manager

Attackers deliberately create pressure.

A message may say:

• “This payment must be completed immediately.”
• “Your account will be disabled today.”
• “Do not discuss this request with anyone else.”
• “The managing director is waiting for confirmation.”
• “Approve this login so the update can finish.”

Employees should be encouraged to slow down and verify any request that creates unusual urgency.

A legitimate colleague or supplier should understand why security procedures must be followed.

Remote and Hybrid Workers

Remote workers may have fewer opportunities to verify a request face to face.

They may also rely heavily on email, instant messaging and cloud platforms.

Attackers can exploit this by impersonating colleagues, IT support staff or senior managers.

Remote working can also introduce risks through:

• Personal devices
• Home routers
• Public Wi-Fi
• Unmanaged applications
• Shared family computers
• Poor physical privacy

Businesses should ensure remote employees receive secure devices, clear guidance and a simple method for reporting concerns.

Older and Less Technically Confident Users

Not everyone has the same level of digital confidence.

Some individuals may find it difficult to distinguish between genuine and fraudulent messages, particularly when attackers copy familiar brands or use official-looking language.

Common scams may involve:

• Fake technical support
• Banking warnings
• Delivery notifications
• Password expiry messages
• Fraudulent invoices
• Government impersonation
• Remote-access requests

Training should be accessible, practical and free from unnecessary technical language.

People should feel comfortable asking for help without embarrassment.

Customers and Service Users

Cyber criminals may also target your customers by pretending to represent your business.

They could use:

• Lookalike email domains
• Fake invoices
• Fraudulent payment details
• Cloned websites
• Social media accounts
• Compromised employee mailboxes

If customers are deceived by someone impersonating your organisation, your reputation may still suffer even when your own systems were not directly compromised.

Controls such as SPF, DKIM and DMARC can help reduce email impersonation. Businesses should also provide customers with clear guidance about how genuine payments and communications are handled.

Employees With Access to Sensitive Data

Human resources, legal, healthcare and administrative teams may hold valuable personal or confidential information.

Attackers may seek:

• Employee records
• Identity documents
• Payroll data
• Medical information
• Contracts
• Customer databases
• Login credentials

A request for sensitive information should always be verified, particularly when it is unexpected or comes from outside the organisation.

Access should also be restricted so employees can only reach the information required for their roles.

Businesses Using Older Technology

Unsupported systems are attractive to attackers because newly discovered vulnerabilities may never be fixed.

Older technology can include:

• Unsupported operating systems
• Legacy servers
• Outdated firewalls
• Old applications
• Unpatched network equipment
• Obsolete remote-access tools

A system can continue working normally while still containing serious security weaknesses.

Businesses should maintain an accurate technology inventory and plan upgrades before products reach the end of support.

Organisations During Change

Periods of change create opportunities for cyber criminals.

This may include:

• Business acquisitions
• Office moves
• Staff turnover
• New suppliers
• Leadership changes
• Major projects
• System migrations
• Rapid recruitment

During these periods, normal procedures may be less clear and employees may expect unusual requests.

Attackers can exploit this confusion by impersonating new colleagues, suppliers or project partners.

Security responsibilities should remain clear throughout any significant business change.

Charities and Community Organisations

Charities may hold sensitive information about supporters, beneficiaries and donors.

They may also depend on volunteers, shared systems and limited budgets.

Cyber criminals may assume these organisations have weaker controls or less access to specialist support.

Charities should still implement fundamental protections such as:

• Multi-factor authentication
• Secure backups
• Employee and volunteer training
• Email protection
• Supported software
• Limited user permissions
• Incident response procedures

The value of the information held—not the size of the organisation—determines the risk.

How Attackers Exploit Vulnerability

Cyber criminals commonly use psychological techniques rather than technical sophistication.

Urgency

The attacker creates a deadline so the victim acts without checking.

Authority

They impersonate someone senior or influential.

Fear

They threaten account closure, financial loss or disciplinary action.

Trust

They pretend to be a colleague, supplier or support provider.

Curiosity

They use an interesting attachment, confidential document or unexpected message.

Sympathy

They may invent a personal emergency or difficult situation.

Confusion

They use technical language or complex instructions to discourage questions.

Understanding these tactics makes them easier to recognise.

How Businesses Can Protect Vulnerable People

1. Provide Regular Security Awareness Training

Training should cover real situations employees may encounter.

This includes:

• Phishing
• Payment fraud
• Social engineering
• Password security
• Multi-factor authentication
• Suspicious phone calls
• Data handling
• Incident reporting

Training should be repeated regularly and adapted for different roles.

2. Create Clear Verification Procedures

Employees should know exactly how to verify:

• Payment requests
• Bank-detail changes
• Password resets
• Requests for confidential data
• Remote-access requests
• Instructions from senior leaders

Verification should use a trusted and independent contact method.

3. Use Multi-Factor Authentication

MFA can prevent a stolen password from being enough to access an account.

It should protect email, remote access, cloud services and all important business applications.

Employees must also understand that unexpected MFA prompts should never be approved.

4. Limit User Access

Employees should only have the permissions they need.

Reducing access can limit the damage caused by a compromised account or an honest mistake.

Administrator rights should be tightly controlled and reviewed regularly.

5. Protect Email

Advanced email security can help identify:

• Phishing links
• Malicious attachments
• Impersonation
• Spoofed domains
• Suspicious senders
• Malware

External sender warnings and domain authentication can provide additional protection.

6. Keep Systems Updated

Devices, applications, firewalls and network equipment should receive security updates promptly.

Unsupported systems should be replaced or isolated where immediate replacement is not possible.

7. Make Reporting Easy

Employees need a simple and well-publicised way to report suspicious activity.

This could include a report-phishing button, dedicated email address or helpdesk telephone number.

Reports should be treated seriously and without blame.

8. Monitor for Suspicious Activity

Security monitoring may identify:

• Unusual logins
• New administrator accounts
• Suspicious mailbox rules
• Large data transfers
• Disabled security tools
• Repeated failed access attempts
• Unexpected MFA registrations

Alerts should be reviewed promptly by someone capable of responding.

9. Protect Customers From Impersonation

Businesses should monitor their domains, secure their email configuration and communicate clearly with customers.

Customers should know that your organisation will never unexpectedly request passwords or unverified changes to payment details.

10. Prepare for Incidents

Even strong security cannot eliminate every risk.

An incident response plan should explain:

• Who must be contacted
• How accounts will be secured
• How affected devices will be isolated
• How customers will be informed
• Who will contact insurers or regulators
• How systems will be restored

The plan should be tested before it is needed.

Avoid Blaming the Victim

When someone falls for a cyber attack, blame is rarely helpful.

Cyber criminals deliberately design attacks to manipulate people. They test messages, copy trusted brands and exploit normal human behaviour.

Employees who fear punishment may hide mistakes or delay reporting.

A supportive response allows the business to act faster, reduce damage and learn from the incident.

The focus should be on strengthening systems and processes rather than humiliating the person who was deceived.

Vulnerability Is Not a Personal Failure

Anyone can be caught by a convincing attack.

The most experienced employee can make a mistake during a busy day. A senior manager can approve a fraudulent request. A technical user can enter credentials into a realistic login page.

The purpose of cyber security is not to expect perfect behaviour.

It is to create layers of protection so that one mistake does not become a major business incident.
