7 Cyber Risks Every Business Should Know
A practical guide to understanding and defending against today’s most common cyber threats
Introduction
Cybercrime is one of the fastest-growing threats facing businesses today. Global cybercrime costs are projected to reach $10.5 trillion annually by 2025, making it more profitable than the global illegal drug trade. No organization — regardless of size or industry — is immune.
Small and mid-sized businesses are especially attractive targets. Many assume they are too small to be noticed by cybercriminals, but the opposite is true. Attackers know that smaller organizations often have less mature security programs, fewer dedicated IT staff, and reduced budgets for cybersecurity tools — all of which makes them easier and faster to compromise.
This guide walks through the seven most common and damaging cyber risks businesses face today. For each threat, we explain how it works, what the real-world impact looks like, and the concrete steps your organization can take to reduce its exposure.
Risk 1: Phishing Attacks
What It Is
Phishing is a type of social engineering attack where cybercriminals send fraudulent emails, text messages, or social media messages that appear to come from a trusted source — such as a bank, a colleague, a government agency, or a well-known company. The goal is to deceive the recipient into clicking a malicious link, opening a dangerous attachment, or entering login credentials on a fake website.
Modern phishing campaigns are highly sophisticated. Attackers research their targets using LinkedIn, company websites, and social media to craft convincing messages tailored to specific individuals — a technique known as spear phishing. When executives are targeted specifically, it is called whaling.
The Real-World Impact
According to IBM’s Cost of a Data Breach Report, phishing is the most common attack vector and leads to some of the most costly breaches. A single employee clicking the wrong link can give attackers access to your entire network. Consequences include:
• Stolen employee or customer credentials
• Unauthorized wire transfers or payment fraud
• Installation of malware or ransomware
• Regulatory penalties following a data exposure
• Reputational damage and loss of customer trust
How to Protect Your Business
✓ Deploy email filtering and anti-phishing software that flags suspicious messages before they reach inboxes.
✓ Conduct regular phishing simulation training so employees can recognize and report suspicious messages.
✓ Require multi-factor authentication (MFA) on all business accounts so stolen passwords alone are not enough for attackers to log in.
✓ Establish a clear process for employees to report suspected phishing attempts without fear of blame.
✓ Apply domain-based email authentication protocols (DMARC, DKIM, SPF) to reduce spoofing of your own domain.
Risk 2: Ransomware
What It Is
Ransomware is a category of malicious software (malware) that encrypts a victim’s files, databases, or entire systems, rendering them completely inaccessible. The attackers then demand a ransom — typically in cryptocurrency like Bitcoin to preserve anonymity — in exchange for the decryption key needed to restore access.
Modern ransomware gangs often operate on a “Ransomware-as-a-Service” (RaaS) model, meaning technical tools are sold or rented to less-skilled criminals. Attackers also commonly practice double extortion: they encrypt your data AND threaten to publicly leak it if you refuse to pay.
The Real-World Impact
Ransomware attacks have shut down hospitals, schools, government agencies, and manufacturers. The average ransom payment exceeded $800,000 in 2023 — but the total cost including downtime, remediation, and reputational damage is often far higher. Key impacts include:
• Complete operational shutdown, sometimes lasting days or weeks
• Loss of critical business and customer data
• Ransom payments that offer no guarantee of recovery
• Regulatory scrutiny and potential fines for exposed personal data
• Long-term reputational damage with customers and partners
How to Protect Your Business
✓ Maintain regular, tested, offline backups of all critical systems and data — this is your most important defense.
✓ Patch and update operating systems and software promptly to eliminate vulnerabilities attackers exploit.
✓ Segment your network so that if ransomware infects one system, it cannot spread freely to others.
✓ Restrict administrative privileges so most employees cannot install software or make system changes.
✓ Develop and test an incident response plan so your team knows exactly what to do if ransomware strikes.
✓ Consider cyber insurance that specifically covers ransomware incidents, including negotiation services.
Risk 3: Business Email Compromise (BEC)
What It Is
Business Email Compromise (BEC) is a sophisticated scam in which attackers impersonate a trusted person — usually a company executive, a vendor, or a business partner — to manipulate employees into transferring money, sharing sensitive data, or changing payment account details. Unlike phishing, BEC attacks often involve no malware at all; they rely purely on social engineering and deception.
Attackers may compromise a real email account (making the fraud nearly undetectable) or create a look-alike domain (e.g., company-name.co instead of company-name.com). They often study email communication patterns for weeks before striking at the perfect moment, such as during a real estate closing or vendor payment cycle.
The Real-World Impact
The FBI has identified BEC as the costliest cybercrime category, with over $50 billion in global losses reported since 2013. Unlike credit card fraud, wire transfers and ACH payments are extremely difficult to reverse. A single successful BEC attack can result in:
• Six-figure fraudulent wire transfers that cannot be recovered
• Exposure of employee payroll data or W-2 tax information
• Loss of supplier relationships and legal disputes
• Internal mistrust among employees and leadership
• Significant forensic investigation and legal costs
How to Protect Your Business
✓ Establish a strict verbal or secondary email verification process for any payment, account change, or transfer request, regardless of who it appears to come from.
✓ Train employees to recognize the urgency tactics and secrecy requests that are hallmarks of BEC fraud.
✓ Enable email warning banners on messages that originate from outside your organization.
✓ Use MFA on all email accounts to prevent attackers from gaining control of real accounts.
✓ Audit financial controls regularly and implement dual-approval requirements for large transactions.
✓ Alert your bank immediately if you suspect a fraudulent transfer has been made.
Risk 4: Data Breaches
What It Is
A data breach occurs when an unauthorized individual gains access to confidential or protected information. This can include customer personally identifiable information (PII) such as names, Social Security numbers, addresses, and dates of birth; financial data like credit card numbers or bank account details; protected health information (PHI); or proprietary business data.
Breaches can result from external attacks (such as exploiting an unpatched vulnerability), insider threats (a disgruntled or careless employee), or accidental exposure (misconfigured cloud storage or an emailed file sent to the wrong recipient). Once data is stolen, it is frequently sold on dark web marketplaces.
The Real-World Impact
The average cost of a data breach globally is $4.45 million (IBM, 2023). Beyond the financial hit, breaches trigger complex legal and regulatory obligations. Under laws such as GDPR, HIPAA, and various state-level breach notification laws, businesses must:
• Notify affected individuals within strict time windows
• Report to regulators, which may result in substantial fines
• Provide credit monitoring or identity protection services to victims
• Defend against class-action lawsuits from affected customers or employees
• Manage extensive reputational damage that can lead to customer churn
How to Protect Your Business
✓ Maintain a complete data inventory: know exactly what sensitive data you hold, where it is stored, and who can access it.
✓ Enforce the principle of least privilege — employees should only access the data necessary for their role.
✓ Encrypt sensitive data both in transit (using TLS/HTTPS) and at rest.
✓ Conduct regular vulnerability assessments and pe*******on tests to find weaknesses before attackers do.
✓ Establish a documented breach response plan including legal, PR, and notification procedures.
✓ Ensure cloud storage buckets, databases, and file shares are not misconfigured to be publicly accessible.
Risk 5: Weak Password Security
What It Is
Weak password security remains one of the most persistent and preventable vulnerabilities in business cybersecurity. Common problems include using short or simple passwords (e.g., “Password1!”), reusing the same password across multiple accounts, sharing passwords between coworkers, never changing default passwords on devices or software, and failing to remove access for former employees.
Attackers use techniques such as credential stuffing (testing leaked username/password pairs from other breaches), brute-force attacks (automated guessing of passwords), and dictionary attacks (testing lists of common words and passwords). Billions of leaked credentials are freely available to criminals online.
The Real-World Impact
Verizon’s Data Breach Investigations Report consistently finds that over 80% of hacking-related breaches involve compromised or weak credentials. When an attacker obtains a valid set of login credentials, they can:
• Access email, financial, or HR systems undetected for weeks or months
• Move laterally through the network to compromise additional systems
• Exfiltrate customer data, intellectual property, or financial records
• Lock out legitimate users by changing passwords and access settings
• Use your systems and email accounts to attack your customers or partners
How to Protect Your Business
✓ Require long, complex, unique passwords (minimum 12-16 characters) for all business accounts.
✓ Deploy a company-wide enterprise password manager so employees can manage unique passwords without writing them down.
✓ Enforce multi-factor authentication (MFA) on every account, especially email, VPN, and financial systems.
✓ Implement single sign-on (SSO) where possible to reduce the number of passwords employees manage.
✓ Conduct regular audits of user accounts to remove or disable access for departed employees immediately.
✓ Monitor for leaked credentials using threat intelligence services that scan dark web marketplaces.
Risk 6: Third-Party Vendor Risk
What It Is
Modern businesses rely on dozens — sometimes hundreds — of third-party vendors, software providers, cloud services, and IT contractors. Each one that has access to your systems, networks, or data represents a potential attack surface. A vulnerability in a vendor’s systems can become a direct pathway into your own business, even if your own defenses are strong.
Supply chain attacks have grown dramatically. The 2020 SolarWinds breach, in which attackers compromised a widely-used IT management tool and gained access to thousands of organizations including U.S. government agencies, demonstrated how a single vendor compromise can have cascading global consequences.
The Real-World Impact
Third-party breaches can be particularly damaging because businesses may not discover them for a long time and often have limited control over the vendor’s security practices. Consequences include:
• Exposure of your customers’ data through a vendor who processes it on your behalf
• Regulatory penalties since you remain responsible for data your vendors handle
• Business disruption if a critical vendor is taken offline by an attack
• Contractual liability and financial claims from affected customers
• Damage to your reputation even though the breach originated externally
How to Protect Your Business
✓ Build a complete vendor inventory and classify vendors by the level of data access and system integration they have.
✓ Conduct security assessments or request SOC 2 Type II reports, pe*******on test results, or completed security questionnaires before onboarding vendors.
✓ Include cybersecurity requirements, breach notification obligations, and audit rights in all vendor contracts.
✓ Apply the principle of least privilege to vendor access — vendors should only connect to the specific systems they need.
✓ Monitor vendor access logs regularly and revoke access immediately when a vendor relationship ends.
✓ Develop contingency plans for your most critical vendors in case they suffer an outage or breach.
Risk 7: Employee Human Error
What It Is
Despite sophisticated technical defenses, human error remains the leading cause of cybersecurity incidents. Employees make mistakes — and attackers deliberately exploit this. Common examples include clicking on a link in a phishing email, opening a malicious email attachment, sending sensitive files to the wrong recipient, using personal or public Wi-Fi networks for work without a VPN, plugging in unknown USB drives, failing to lock computers when stepping away, and misconfiguring security settings in cloud platforms.
Human error is not simply a training problem — it is a systemic challenge. Overworked, distracted, or undertrained employees operating under time pressure are more likely to make security mistakes. A strong security culture requires both ongoing education and technical controls that reduce the opportunity for errors to occur.
The Real-World Impact
The World Economic Forum estimates that 95% of cybersecurity incidents involve human error as a contributing factor. Mistakes that seem minor in the moment can have major consequences:
• A single misaddressed email can expose sensitive customer or legal information
• Connecting to unsecured Wi-Fi can expose login credentials and session data
• A misconfigured cloud storage bucket can expose millions of customer records publicly
• Falling for a phishing email can give attackers months of undetected network access
• Failing to report a suspected incident delays response and amplifies the damage
How to Protect Your Business
✓ Deliver engaging, regular security awareness training — not just annual checkbox compliance, but ongoing education tailored to real threats your business faces.
✓ Run phishing simulations periodically to test employee awareness and provide immediate, constructive feedback.
✓ Require VPN use for all remote work and strictly prohibit company business on public Wi-Fi without it.
✓ Implement data loss prevention (DLP) tools that flag or block emails containing sensitive information sent to external or unexpected recipients.
✓ Create a blame-free reporting culture — employees who fear punishment will hide mistakes rather than reporting them quickly.
✓ Apply technical controls such as endpoint protection, screen lock policies, and USB device restrictions to reduce the blast radius of human error.
Key Takeaway: Building a Resilient Business
Many of the most damaging cyber incidents begin with surprisingly simple vulnerabilities — an employee clicking the wrong link, a weak password, an unpatched system, or a poorly vetted vendor. The good news is that the majority of these risks are manageable with the right combination of technology, training, processes, and partnerships.
No security program can guarantee zero incidents. That is why cyber insurance has become an essential component of a comprehensive business risk strategy. When an attack does occur, cyber insurance helps organizations respond quickly by providing immediate access to:
• Incident response and forensic experts to contain the breach and identify how it happened
• Legal advisors experienced in breach notification requirements and regulatory compliance
• Public relations specialists to manage communications with customers, media, and regulators
• Ransomware negotiation specialists who can engage with attackers on your behalf
• Financial coverage for business interruption losses, ransom payments, regulatory fines, and litigation costs
Cybersecurity is not a one-time project — it is an ongoing program that evolves alongside the threat landscape. Businesses that invest in awareness, preparedness, and the right insurance coverage are significantly better positioned to withstand attacks, recover quickly, and protect the customers and stakeholders who depend on them.
