Many small business owners ask: “Why should I care about cybersecurity? I’m too small to be a target.” But the reality is sobering, many criminals increasingly prefer small businesses.

A Mastercard survey (2025) found that 46% of SMBs worldwide have experienced a cyberattack and nearly 1 in 5 victims closed their doors afterward.¹

In the U.S., the Small Business Administration highlights a Hiscox survey showing 41% of small businesses were attacked in 2023. The median cost of these attacks was $8,300. in times of tight margins, this impact can be very damaging.²

And according to the StrongDM industry blog, phishing and social engineering attacks disproportionately target small firms, not just big brands.³

In other words, small doesn’t mean safe, it means vulnerable.

Behind each of the statistics above are stories of real business owners. One such story is told in The Times in an article titled My company thrived for 150 years — then Russian hackers brought it down in three months⁴. This story describes how KNP, a logistics company had their systems crippled by a ransomware attack and never fully recovered. In the end “KNP went into administration in September of last year, with 730 people made redundant”⁴.

This story is just one of many. Businesses that have been attacked have lost access to customer records, seen sales vanish, or had their reputations was destroyed. Some of these businesses had to close their doors after a single click on the wrong email link. For small teams, even a modest disruption can feel catastrophic.

Top Threats

Understanding the types of attacks most often aimed at small businesses is the first step toward reducing that risk. Let’s look at the common scenarios that play out time and again, and how they affect organizations with limited staff and budgets.

Social engineering

Social engineering is a broad category of threats that exploit human trust rather than technical flaws. Common examples include phishing (email attacks), smishing (fraudulent text messages), vishing (voice-based scams), and quishing (malicious QR codes). Although the delivery methods differ, the goal is the same: tricking the victim into clicking a link, sharing sensitive information, or taking an action that exposes the business to compromise.

A typical example might be an urgent email or text claiming to be your “final notice” to pay a fine before an arrest warrant is issued. These attacks can feel highly credible. The era of obvious scams—messages full of misspellings or offers from imaginary princes is largely behind us. Today, AI-powered tools allow attackers to craft polished, convincing messages that are far harder to recognize as fraudulent.

Ransomware

Ransomware is malicious software that encrypts a victim’s data, systems, or files and demands payment to restore access. It typically arrives through phishing emails, malicious downloads, or exploited vulnerabilities. One present on one system, it can spread rapidly across networks. The impact is immediate: business operations grind to a halt as critical data becomes inaccessible. Attackers may also threaten to leak stolen information if the ransom isn’t paid. For small businesses, the consequences are especially severe. These range from costly downtime and reputational damage to regulatory violations or, in the worst cases, permanent closure.

Compromised credentials

Compromised credentials—usernames and passwords that have been stolen, guessed, or leaked—pose one of the most serious threats to small businesses. Once attackers gain valid login information, they can bypass traditional security controls and move through systems unnoticed, often using the same accounts employees rely on every day. This can lead to unauthorized access to email, banking, cloud services, and sensitive customer data. Stolen credentials are also commonly sold on the dark web, enabling multiple attackers to exploit them. For a small business, the consequences include financial fraud, data breaches, reputational damage, and potential regulatory penalties—all from a single weak or reused password.
