Total Defense Security Tip of the Day

The most common entry points hackers use against small businesses
Small businesses are often told they need “better cybersecurity,” but that advice can feel vague. The more useful question is: How do hackers actually get in? Once you understand the most common entry points, it becomes much easier to focus your time, budget, and security habits where they matter most.
Small businesses are attractive targets because they often rely on the same technology as larger companies — email, cloud apps, payment systems, websites, remote access tools — but may not have a full-time security team watching everything.
Why small businesses are frequent targets
Cybercriminals don’t always handpick victims. Many attacks are automated, scanning the internet for weak passwords, outdated software, exposed remote access tools, or employees who might click a malicious link.
That risk is real. VikingCloud’s 2025 SMB Threat Landscape Report found that 1 in 3 small and medium-sized businesses were hit by a successful cyberattack in the previous year. That’s a strong reminder that “we’re too small to be targeted” is no longer a safe assumption.
Stolen passwords and weak logins
One of the most common ways attackers break in is through stolen or reused passwords. If an employee uses the same password across personal and business accounts, one breach elsewhere can become a doorway into company email, cloud storage, payroll, or banking systems.
According to Verizon’s 2025 Data Breach Investigations Report, credential abuse was one of the leading initial attack vectors, involved in 22% of breaches, while vulnerability exploitation accounted for 20%. You can review the report directly from Verizon’s 2025 DBIR.
Phishing emails and fake messages
Phishing is still a major entry point because it targets people, not software. Hackers send emails, texts, or messages that look like invoices, delivery notices, password reset alerts, bank warnings, or cloud file shares.
A successful phishing attack may trick someone into:
- Entering a password on a fake login page
- Downloading malware
- Approving a fake payment request
- Sharing sensitive business data
Unpatched software and exposed systems
Hackers also look for outdated software, especially internet-facing systems like VPNs, firewalls, servers, and remote access tools. If a security patch is available but not installed, attackers may exploit that gap before a business even realizes there’s a problem.
Remote access tools
Remote desktop tools, VPNs, and cloud admin portals are useful, but they can be dangerous if they’re poorly protected. Attackers often search for exposed login pages and attempt stolen passwords, password spraying, or brute-force attacks.
To reduce risk:
- Require multi-factor authentication
- Limit access to trusted users
- Disable unused accounts
- Review login activity
- Keep remote access software patched
Cloud apps and file sharing mistakes
Small businesses rely heavily on cloud storage, shared folders, and collaboration tools. Mistakes happen when files are shared with “anyone with the link,” old employees keep access, or sensitive documents get uploaded to personal accounts.
Protect cloud apps by:
- Reviewing sharing permissions regularly
- Removing former employees immediately
- Using role-based access
- Turning on login alerts
- Requiring MFA for all accounts
How small businesses can reduce these risks
Start with the basics:
- Use a password manager
- Turn on MFA for email, banking, cloud apps, and admin accounts
- Patch software quickly
- Train employees to spot phishing
- Back up critical files
- Use endpoint protection on every device
- Review user access monthly
- Create a simple incident response plan
Hackers usually don’t need a complicated way in. They look for common openings: stolen passwords, phishing emails, unpatched systems, exposed remote access tools, and misconfigured cloud apps. Small businesses that close those doors first can dramatically reduce their risk without needing an enterprise-sized security budget.
