Attack Vectors

Common Cyberattack Vectors Explained

Understanding how attackers get into systems is the first step to strengthening your defenses. The methods listed below are the most common entry points used by cybercriminals to target small and mid-sized businesses. This includes local service providers, retail operations, healthcare practices, and professional firms.

Each of these attack types is actively used in real-world breaches across industries. Recognizing them helps you evaluate your own exposure and identify areas where additional protection may be needed.

Phishing

Phishing refers to emails, text messages, or calls that trick recipients into revealing sensitive information. This might include login credentials, financial data, or access to internal systems. Messages often appear to come from trusted services such as Google, Microsoft, or payment providers.

• Often uses fake login pages or urgent-sounding alerts
• Designed to look legitimate at a glance
• Frequently delivered through email, SMS, or phone calls

See real-world phishing examples.

Brute Force Attacks

Brute force attacks use automated tools to guess usernames and passwords by rapidly trying different combinations. They target websites, email portals, and remote access tools. These attacks are often invisible until access is gained.

• Exploits weak or reused passwords
• Targets common login URLs such as /wp-admin or /login
• Runs continuously using large databases of known passwords

Check whether your login protections are in place.

Outdated Software Exploits

When plugins, themes, or software tools are not kept up to date, attackers can exploit known vulnerabilities. These flaws are often documented in public databases, and automated scanners search the web looking for unpatched systems to target.

• Affects websites, plugins, server software, and integrations
• Includes risks from inactive or disabled plugins
• Updates that are missed or delayed can be exploited quickly

Ransomware

Ransomware is malware that encrypts your systems or files and demands payment to restore access. In many modern attacks, data is stolen before encryption occurs, increasing the pressure to pay.

• Frequently spread through phishing or outdated software
• Targets businesses of all sizes, especially those that handle sensitive data
• Can cause operational downtime, data loss, and reputation damage

Supply Chain Attacks

Supply chain attacks occur when a trusted vendor or third-party service provider is compromised. This method allows attackers to gain access to multiple businesses through a single point of entry. Common targets include billing software, cloud storage platforms, scheduling tools, and other integrated systems.

• Exploits software or services that your business depends on
• Can result in breaches even when your internal systems are secure
• Requires careful evaluation of vendors and regular audits

Learn how to evaluate your vendor security posture.

These are just a few of the most common ways attackers gain access to small business systems and sensitive data. Whether you operate a healthcare clinic, a retail storefront, or a service-based business, the same threats apply.
