According to Tessian, 26% of employees have clicked on a phishing email in the past year.
Luckily, email security is improving; however, it only takes one mistake for an employee to click on a link that can have devastating consequences for a business.
Despite significant advances in email security, phishing remains one of the biggest cyber security risks facing businesses in 2026.
Cybercriminals are now using artificial intelligence to create highly convincing phishing emails, clone writing styles, impersonate executives, and even generate realistic voice messages. The result is that phishing attacks are becoming more sophisticated, harder to detect, and far more likely to bypass traditional security measures.
According to industry research, human error continues to play a major role in successful cyber attacks, making employee awareness just as important as technical security controls.
The good news is that modern security technologies, combined with effective staff training, can dramatically reduce your risk.
Below shows an outline of the most common types of Phishing attacks.
The Most Common Types of Phishing Attacks
Bulk Phishing
Bulk phishing is still the most common type of phishing attack.
Cybercriminals send the same email to thousands of recipients hoping that a small percentage will click a malicious link, download an infected attachment or disclose sensitive information.
Common warning signs include:
| Warning Sign | Why It’s Suspicious |
|---|---|
| Urgent requests | Pressure to act immediately without thinking |
| Unexpected invoices or payment requests | Designed to create panic |
| Shortened or unfamiliar links | Used to hide malicious websites |
| Poor grammar or unusual wording | Although AI is reducing these mistakes |
| Sender address doesn’t match the organisation | A common impersonation tactic |
| Requests for gift cards, bank transfers or login details | Legitimate organisations rarely ask this by email |
Today’s phishing emails are often written using AI, making them far more professional than those seen just a few years ago.
Spear Phishing
Rather than sending thousands of generic emails, spear phishing targets specific individuals.
Attackers research their victims using publicly available information from company websites, LinkedIn, social media and previous data breaches.
They may know:
- Your role within the business
- Your colleagues’ names
- Recent company announcements
- Suppliers and customers
- Projects you’re working on
This information allows criminals to create personalised emails that appear completely legitimate.
Whaling
Whaling is a specialised form of spear phishing aimed at senior leadership, including directors, finance teams and business owners.
These attacks often attempt to:
- Approve fraudulent invoices
- Redirect payroll payments
- Change supplier bank details
- Gain access to Microsoft 365 or Google Workspace accounts
- Steal confidential company data
Because executives typically have access to sensitive systems, these attacks can cause significant financial and reputational damage.
Business Email Compromise (BEC)
Business Email Compromise has become one of the fastest-growing cyber threats.
Rather than relying on malware, attackers impersonate trusted individuals such as:
- Managing Directors
- Finance Managers
- HR departments
- Existing suppliers
- Customers
The email often appears genuine and requests an urgent payment or confidential information.
Many BEC attacks now use AI to mimic an executive’s writing style, making them increasingly difficult to detect.
Smishing and Vishing
Phishing is no longer limited to email.
Cybercriminals increasingly target businesses using:
- Smishing – fraudulent SMS messages
- Vishing – voice phishing via telephone calls
- QR code phishing (Quishing) – malicious QR codes directing users to fake login pages
AI-generated voice technology has also introduced convincing voice cloning attacks, where criminals impersonate senior staff or trusted contacts over the phone.
How Businesses Can Protect Themselves
There is no single solution to phishing. The most effective defence combines technology, employee awareness and strong security policies.
1. Modern Email Security
Traditional spam filters are no longer enough.
Modern email security platforms use artificial intelligence and behavioural analysis to identify threats before they reach your inbox.
At Cheeky Munkey, we help businesses deploy advanced email protection solutions that include:
| Security Capability | Business Benefit |
|---|---|
| AI-powered phishing detection | Identifies sophisticated phishing attempts before users see them |
| Behavioural analysis | Detects unusual account activity and insider threats |
| Business Email Compromise protection | Prevents executive impersonation attacks |
| Safe link and attachment protection | Scans URLs and files in real time |
| DMARC, DKIM and SPF implementation | Prevents domain spoofing and improves email authentication |
| Automated investigation and remediation | Removes malicious emails across the organisation quickly |
| Data Loss Prevention (DLP) | Prevents sensitive business information leaving the organisation |
These solutions work alongside Microsoft 365 and Google Workspace to provide additional layers of protection.
2. Build a Human Firewall
Technology can stop most phishing attacks, but employees remain the final line of defence.
Creating a “human firewall” means giving staff the knowledge and confidence to identify suspicious activity before it becomes a security incident.
Effective cyber security awareness training should cover:
- How modern phishing attacks work
- AI-generated phishing techniques
- QR code scams
- Business Email Compromise
- Password security
- Safe browsing habits
- Reporting suspicious emails quickly
Regular phishing simulations also help reinforce good habits and identify areas where additional training may be beneficial.
3. Enable Multi-Factor Authentication (MFA)
Even if an attacker steals an employee’s password, Multi-Factor Authentication (MFA) can prevent unauthorised access.
MFA requires users to verify their identity using a second authentication factor, such as:
- Microsoft Authenticator
- Mobile authentication apps
- Security keys
- Biometrics
Implementing MFA across all business accounts remains one of the simplest and most effective cybersecurity measures available.
4. Monitor Your Security Continuously
Cyber threats evolve every day.
Businesses should regularly review:
- Email security configurations
- Microsoft 365 security settings
- User permissions
- Endpoint protection
- Backup and recovery processes
- Vulnerability management
Ongoing monitoring helps identify potential risks before they become serious incidents.
Why a Layered Security Approach Matters
No single security product can stop every phishing attack.
The strongest defence combines:
- Advanced AI-powered email security
- Employee cyber awareness training
- Multi-Factor Authentication
- Strong identity management
- Endpoint Detection and Response (EDR)
- Continuous monitoring and threat detection
- Secure backup and disaster recovery
Together, these layers significantly reduce the likelihood of a successful cyber attack.
