Phishing Attack Methods
Phishing continues to be a major cyber threat, with over 260,000 attacks recorded in July 2021 – the highest monthly figure since 2004.
4 Main Phishing Categories
Phishing attacks generally fall into these four types:
- Email Phishing: This is the most common type, involving mass emails that impersonate trusted organisations. Attackers often aim to steal login credentials, accounting for 64% of phishing cases. For example, in 2017, fake Amazon shipping updates included a Word file that installed Locky ransomware.
- Spear Phishing: Unlike mass attacks, this method targets specific individuals or organisations with tailored messages. In 2015, Sony Pictures suffered a breach when attackers used fake Apple ID emails, leading to losses of around $83 million.
- SMS Phishing (Smishing): Scammers use text messages to impersonate entities like banks or government agencies. These messages often contain urgent requests and malicious links, especially designed for mobile users [1].
- Voice Phishing (Vishing): This approach involves phone calls where attackers pose as legitimate representatives to extract sensitive information.
Warning Signs of Phishing
Spotting phishing attempts is key, and staff should be trained to recognize these red flags:
| Warning Sign | Description | Example |
|---|---|---|
| Urgency Tactics | Messages pressuring immediate action | “Your account will be terminated in 24 hours unless verified” |
| Suspicious Senders | Email addresses that are slightly altered or fake | sender@app1e-support.com instead of apple.com |
| Irregular Procedures | Requests that bypass normal company protocols | Direct wire transfer requests from executives |
| Credential Requests | Unexpected requests for sensitive information | Forms asking for multiple account passwords |
“Everyone is a target in today’s cyberwar climate, and email security is usually the first line of defence.” – Cofense Email Security
One high-profile example is the 2016 Crelan Bank incident, where attackers used a Business Email Compromise (BEC) scam. By forging the CEO’s stamp and signature, they tricked the finance team into approving a $75.8 million transfer [4][5].
To combat these threats, organizations need a well-prepared workforce. Proper training can cut phishing-related costs by 50% [3]. IT managers should stress that legitimate companies will never ask for sensitive information via unsolicited messages. Advanced email filters and proactive employee education remain critical defenses.
Email Security Measures
Today’s email security relies heavily on AI-driven filters and consistent updates to tackle ever-changing phishing threats. Below, you’ll find a breakdown of how to set up and improve these defenses effectively.
Email Filter Setup
Using a mix of AI detection and rule-based filtering is key. Tools like Microsoft Defender for Office 365 can enforce anti-phishing policies. Here’s a quick look at some critical features:
| Security Feature | Purpose | Implementation |
|---|---|---|
| Anti-spoofing Protection | Stops impersonation attempts | Enable spoof intelligence in the Defender portal |
| DMARC Validation | Confirms sender legitimacy | Set policies to quarantine or reject failing messages |
| Safety Indicators | Alerts users to suspicious emails | Activate “via” tags and authentication warnings |
| AI-based Detection | Analyzes threats in real-time | Use machine learning to identify threat patterns |
AI tools can detect 51% more threats, including 88% of emails missed by older systems.
Filter Optimization Guide
To get the most out of your email filters, follow these steps:
- Focus on sender reputation to ensure important emails aren’t flagged incorrectly.
- Use layered rules to evaluate sender authentication, links, attachments, language patterns, and behavior.
- Turn on real-time URL scanning and automated incident response for added protection.
Regular maintenance is essential. IT managers should review filter performance every month and tweak settings to address new threats. Modern tools have reduced manual investigation efforts by 94% thanks to smarter defences.
For extra protection, consider adding phishing-specific tools alongside your gateway filters. Automate quarantines and keep detailed logs to stay compliant.

Staff Training for Phishing Defense
Employee training is one of the most effective ways to prevent data breaches. In fact, poor training accounts for up to 80% of breaches. To make a real impact, training programs need careful planning and consistent follow-through.
Running Phishing Tests
Phishing simulations are a great way to measure how prepared your team is. The best times to schedule these simulations are between 9:30–10:00 AM and 3:00–4:00 PM on workdays. These time slots tend to yield better engagement and more accurate results.
| Testing Component | Implementation Guide | Success Metrics |
|---|---|---|
| Initial Assessment | Send baseline tests to pinpoint vulnerable teams | Email open rates, click-through rates |
| Targeted Training | Focus on teams with high failure rates | Fewer compromised accounts |
| Progressive Difficulty | Start simple and increase complexity over time | Higher reporting rates |
| Real-world Scenarios | Use examples that mimic current threats and brands | Employee feedback and engagement |
| Continuous Monitoring | Track progress over 3–6 months | Quantifiable improvement |
“Fix the basics, protect first what matters for your business and be ready to react properly to pertinent threats.” – Stephane Nappo, CISO of Groupe SEB [8]
These steps can help you create a training program tailored to your organisation’s specific needs.
Security Training Program Steps
Given the financial and reputational damage caused by breaches, it’s essential to use insights from phishing simulations to shape a well-rounded training program.
- Risk Assessment and Planning
Design training modules tailored to different groups, such as remote workers, contractors, and executives. - Content Development
Cover key topics like:- Data privacy and compliance
- Password management and authentication
- Identifying phishing attempts
- Reporting incidents
- Basic cybersecurity practices
- Implementation Strategy
Use a mix of interactive videos, hands-on simulations, role-playing, and regular quizzes to keep the training engaging.
Track progress with these metrics:- Phishing simulation failure rates
- Number of reported suspicious emails
- Time taken to report incidents
- Feedback from employees
Regular updates are a must. Assign a security manager to monitor new threats and refresh training materials as needed [10]. This approach not only keeps your team informed about the latest phishing tactics but also builds a strong, proactive security culture.
Multi-Factor Authentication Setup
Cyberattacks have spiked by 400% since pre-COVID times, making multi-factor authentication (MFA) a key defence. By adding extra layers of security, MFA helps prevent phishing attacks from succeeding, even if login credentials are stolen.
Choosing the Right MFA Method
Selecting the right MFA method means finding the right balance between security and ease of use. A Google study highlights how different methods perform:
| MFA Method | Security Level | Blocking Rate | Key Features |
|---|---|---|---|
| Security Keys | Highest | 100% | Hardware-based, phishing-proof |
| Authenticator Apps | High | 90–100% | Push notifications, offline use |
| SMS Codes | Moderate | 76–100% | Risk of SIM cloning |
Microsoft suggests using passwordless options like Windows Hello or FIDO2 for the best protection [14]. It’s also smart to have users register multiple methods as backups.
Once you’ve picked the right MFA method, the next step is to roll it out smoothly across your organization.
Steps for Deploying MFA
Adding MFA to your security measures – alongside tools like email filtering and employee training – can greatly reduce your exposure to phishing attacks.
1. Plan Ahead
Start by analyzing your organization’s needs. Consider integrating single sign-on (SSO) with MFA to simplify access while keeping security tight.
2. Roll Out Gradually
Begin with a pilot group to identify and fix any issues before expanding MFA organisation-wide [17]. Use tools like Azure Monitor workbooks and usage reports to track how well the rollout is going [16].
3. Educate and Train Users
Explain why MFA is critical and provide easy-to-follow setup instructions.
4. Follow Best Practices
- Set up Conditional Access policies based on risk levels.
- Have a rollback plan ready for emergencies [18].
- Enable combined security information registration to make onboarding easier [14].
MFA isn’t a “set it and forget it” solution. With credential theft still a major issue, it’s crucial to regularly review and update your MFA policies to stay ahead of new threats.
How Password Managers Stop Phishing
Phishing continues to be one of the most persistent cyber threats, with attackers exploiting human error to steal login credentials through emails, texts, and phone calls. Even the most security-aware employees can fall for sophisticated phishing attempts. This is where password managers become an essential component of your organisation’s defence strategy.
Why Password Managers Are a Critical Layer of Defence
Business-grade password managers, such as Uniqkey, offer multiple protections that directly address phishing threats:
- Domain-Aware Autofill – Quality password managers verify website domains before autofilling credentials. This prevents users from entering passwords on malicious websites that imitate legitimate services.
- Reduced Manual Entry– Employees no longer need to manually enter passwords. This reduces the risk of inadvertently typing credentials into phishing sites designed to deceive.
- Stronger, Unique Credentials – Password managers generate and store complex, unique passwords for each service, limiting the damage if any single set of credentials is compromised.
- Centralised Oversight & Rapid Response – Business password managers enable IT teams to centrally manage credentials. In the event of a breach, access can be revoked or changed immediately across the organisation.
- Secure Sharing Without Revealing Passwords – Teams can share access without exposing actual passwords, significantly lowering the risk of phishing via social engineering.
Password managers like Uniqkey are most effective when paired with ongoing phishing simulations and security awareness training. Research shows that well-trained employees can reduce phishing-related costs by up to 50%.
By combining technical safeguards with a knowledgeable workforce, your organisation can significantly reduce the likelihood of successful phishing attacks, even when a phishing email slips past your primary filters.
Conclusion
Stopping phishing attacks requires a mix of strong technical defences and well-prepared employees. Data reveals a 40% rise in credential phishing attacks over the past year, with three-quarters of breaches exploiting human error, and one in three users unable to identify phishing attempts.
To strengthen your defenses, focus on these key areas:
- Technical Protections: Use email authentication protocols like DKIM, DMARC, and SPF. Enable multi-factor authentication (MFA) and keep anti-phishing tools up to date.
- Employee Training: Offer regular security awareness programs, including phishing simulations to improve detection skills.
- Incident Handling: Create clear guidelines for reporting and managing phishing attempts quickly and effectively.
- Ongoing Updates: Regularly review and upgrade your security measures to stay ahead of new threats.
These steps align with the strategies we’ve discussed around email security, employee education, and 2FA/MFA deployment. Together, they form a strong, evolving defense system.
