Top 7 Phishing Scams Targeting Businesses in 2025 and How to Avoid Them

In 2025, email phishing attacks remain the #1 threat to businesses. Despite advances in cybersecurity, phishing continues to evolve—leveraging AI-generated emails, deepfakes, and advanced spoofing techniques to trick employees, compromise systems, and steal sensitive data.

According to recent reports, over 90% of breaches begin with a phishing email, costing businesses billions in damages, compliance fines, and lost customer trust. The risk is even higher for industries like finance, healthcare, technology, and professional services, where attackers target high-value data.

In this blog, we’ll break down the Top 7 phishing scams targeting U.S. businesses in 2025—and more importantly, share practical ways to defend your organization.

1. AI-Powered Business Email Compromise (BEC)

Cybercriminals are increasingly using AI-driven text generators to create emails that look and sound exactly like they came from a trusted executive, client, or vendor. These emails often carry a sense of urgency, pressuring employees into approving payments, sharing login credentials, or processing fake invoices without proper verification. Because the language is polished, context-specific, and free of common phishing red flags, many employees fail to recognize the danger until it’s too late. Unlike older phishing scams that relied on obvious spelling or grammar mistakes, AI-generated emails are nearly indistinguishable from legitimate communication. The result is a highly effective form of fraud that puts businesses at serious risk of financial loss, compliance breaches, and reputational damage.

How to avoid it:

• Implement multi-factor authentication (MFA) for all financial approvals.
• Train employees to verify requests via a second channel (phone, Teams, etc.).
• Deploy AI-based email security filters to detect subtle spoofing patterns.

2. Deepfake CEO Scams

Deepfake technology has rapidly advanced, and in 2025, cybercriminals are exploiting it to launch CEO fraud scams that look and sound alarmingly real. Using AI-generated voice and video, attackers impersonate senior executives during calls or video meetings, pressuring employees to make urgent payments, approve wire transfers, or share confidential data. Unlike traditional phishing, these scams create a powerful sense of authority and urgency, making employees feel they must act immediately. Since the requests appear to come directly from top leadership, victims rarely question them until it’s too late. For businesses, deepfake CEO scams can cause severe financial losses and reputational damage, especially when attackers target finance or operations teams.

How to avoid it:

• Establish verification policies for all high-value transactions.
• Educate staff about deepfake risks and encourage skepticism of unusual requests.
• Monitor for unusual behavior patterns in communication channels.

3. Fake SaaS Login Portals

Cybercriminals are increasingly targeting businesses with fake SaaS login portals that mimic platforms like Microsoft 365, Google Workspace, or Salesforce. Employees receive an email prompting them to log in—often framed as a security update, password reset, or urgent access issue. Once they enter their credentials, attackers capture the information and use it to access corporate systems, steal data, or launch further attacks. These fraudulent portals are often indistinguishable from the real thing, making them especially dangerous for busy employees. With so many organizations relying on SaaS platforms for daily operations, this scam has become one of the most effective ways for hackers to compromise entire networks.

How to avoid it:

• Deploy Single Sign-On (SSO) with conditional access.
• Train staff to check URLs carefully before logging in.
• Use phishing-resistant MFA (FIDO2 keys, biometrics).

4. Vendor & Supply Chain Spoofing

Vendor and supply chain spoofing has become a major threat as businesses increasingly rely on third-party vendors and partners. In this attack, cybercriminals either compromise a legitimate vendor’s account or create a fake domain that closely resembles a trusted supplier’s. They then send fraudulent invoices, payment instructions, or requests that appear authentic, tricking employees into transferring money or sharing sensitive data. Because these messages seem to come from established business relationships, they often bypass suspicion and traditional security checks. The financial and reputational damage from falling victim to such scams can be devastating, especially in industries with complex supply chains like manufacturing, finance, and healthcare.

How to avoid it:

• Set up vendor verification protocols.
• Use Domain-based Message Authentication, Reporting & Conformance (DMARC) to prevent domain spoofing.
• Continuously monitor supply chain risks.

5. Phishing via Collaboration Tools

With the rise of hybrid work, platforms like Microsoft Teams, Slack, and Zoom have become core to business operations—but they’ve also become new attack surfaces. Cybercriminals are now embedding phishing links, malicious files, or fake meeting invites directly inside these collaboration tools, bypassing traditional email security filters. Since messages appear to come from trusted colleagues or internal systems, employees are far more likely to click without hesitation. This type of phishing is particularly dangerous because it blends seamlessly into daily workflows, making detection difficult. For businesses, one compromised account inside these platforms can quickly spread malware, steal credentials, or expose sensitive conversations.

How to avoid it:

• Enable security controls within collaboration platforms.
• Train employees to avoid clicking unknown links inside chats.
• Use cloud access security brokers (CASBs) for visibility.

6. Credential Harvesting Through QR Codes (Quishing)

A rising threat in 2025 is QR code phishing, often called Quishing. Cybercriminals embed malicious QR codes in emails, websites, or even printed materials like posters and flyers. When scanned, these codes redirect unsuspecting employees to fraudulent login pages designed to harvest credentials or install malware on their devices. What makes quishing particularly dangerous is its ability to bypass traditional email filters—since the malicious link is hidden inside the QR code itself. With businesses increasingly relying on mobile devices, this method of phishing is becoming a preferred choice for attackers. Left unchecked, it can compromise entire networks by stealing sensitive employee or client data.

How to avoid it:

• Educate staff on the risks of scanning unknown QR codes.
• Deploy mobile device management (MDM) with secure browsing controls.
• Monitor unusual logins from mobile devices.

7. Fake Compliance & Security Alerts

Another rising phishing tactic in 2025 involves fake compliance and security alerts. Cybercriminals impersonate regulators, government agencies, or even internal IT teams to send urgent messages demanding immediate action. These emails may claim that your business is out of compliance with HIPAA, IRS, or PCI DSS rules and pressure employees to log in, update credentials, or submit sensitive data. Fear-driven phishing works because it exploits the urgency of compliance deadlines and the fear of penalties or audits. For businesses, falling for such scams can expose confidential data, lead to regulatory fines, and severely damage trust.

How to avoid it:

• Train employees to recognize red flags in compliance emails.
• Verify all requests directly with the regulatory body.
• Partner with a managed security provider to monitor threats.
