What Are the Most Common Cybersecurity Threats for Businesses

In this article, we’ll also dive into future information security challenges and risks related to connecting your business to the internet.

Top 5 Cybersecurity Threats That Face Small-to-Medium-Sized Businesses (SMB) or Enterprises (SME)

Small and medium-sized businesses (SMBs) and enterprises (SMEs) may lack the extensive security budgets of large corporations, but they face the same types of cybersecurity threats. In fact, SMBs are frequently targeted because cybercriminals know that these businesses often have weaker defenses. Here are the top 5 cybersecurity threats for SMBs and SMEs:

1. Phishing Attacks

Phishing remains one of the biggest cybersecurity threats to businesses. These attacks involve cybercriminals impersonating legitimate contacts—such as colleagues, vendors, or banks—via email to trick employees into revealing sensitive information or installing malware. Phishing scams are often disguised as urgent requests or important updates, making them hard to detect.

Anecdote: A small logistics company fell victim to a phishing scam where an employee received an email that appeared to come from a trusted supplier. The email requested payment for an “unsettled invoice,” and when the employee clicked on the link, malware was installed on the company’s computer system, locking them out of vital files. The business ended up losing thousands of dollars in ransom payments.

How to Protect Against Phishing Attacks:

Educate employees on how to recognize phishing emails.
Use anti-phishing software to filter out malicious emails.
Implement two-factor authentication (2FA) to add an extra layer of security to login processes.

2. Ransomware Attacks

Ransomware attacks are particularly devastating for small businesses because they often don’t have adequate backups or recovery systems in place. In these attacks, hackers use malicious software to lock business systems or encrypt files, rendering them inaccessible until a ransom is paid. However, paying the ransom doesn’t always guarantee recovery of the data.

Anecdote: In 2023, a small healthcare provider in Texas had its patient records encrypted by ransomware. The provider paid the ransom, but the hackers still refused to unlock the files, leading to patient lawsuits and significant financial losses.

How to Protect Against Ransomware:

Back up your data regularly using cloud-based solutions or external storage devices.
Keep systems and software up to date with the latest security patches to prevent vulnerabilities.
Install anti-ransomware software to detect and block ransomware threats.

3. Weak Passwords

Weak passwords are one of the most common vulnerabilities in any business. Hackers can use brute force attacks to guess weak passwords or use password-cracking software to gain access to business accounts. This can lead to stolen customer data, financial loss, or unauthorized access to sensitive information.

How to Protect Against Weak Passwords:

Use a password manager to generate and store complex, unique passwords for each account.
Enforce password policies that require at least 15 characters with a mix of letters, numbers, and special characters.
Require multi-factor authentication (MFA) for accessing sensitive systems.

4. Insider Threats

While many businesses focus on external threats, insider threats can be just as dangerous. These occur when employees (either maliciously or accidentally) expose sensitive data or give unauthorized access to critical systems. Disgruntled employees, in particular, pose a high risk of insider attacks.

How to Protect Against Insider Threats:

Restrict access to sensitive data and systems based on employee roles.
Implement data loss prevention software to monitor and block suspicious activity.
Regularly train employees on cybersecurity protocols.

5. Outdated Software

Using outdated software with unpatched security vulnerabilities is like leaving the front door of your business unlocked. Cybercriminals actively search for businesses that haven’t updated their systems, allowing them to exploit weaknesses and gain unauthorized access.

How to Protect Against Outdated Software:

Set up automatic updates for all systems and applications to ensure you’re running the latest security patches.
Conduct regular vulnerability assessments to identify and address any outdated software.
Decommission legacy systems that are no longer supported by vendors.
