Crypto-Mining via Phishing – Stop Cryptojacking with Awareness Training
The silent threat of cryptojacking in the Netherlands
Phishing emails will still be the most common entry point for cybercriminals in 2025. Where previously passwords and bank data were mostly captured, we now see a worrying trend: crypto-mining via phishing. Hackers unwittingly install mining software as soon as an employee makes one wrong click. The result? Slowed down systems, increased energy costs and a significant security risk.
Dutch SMEs are especially vulnerable. Employees are often the first line of defense, but without proper training they are also the weakest link. Research shows that 88% of successful attacks start with employees without awareness training.
At ALTA-ICT, we help companies transform employees into the strongest layer of security. With ISO27001-certified awareness programs, we ensure that phishing attempts are recognized, cryptojacking is prevented and incidents are measurably reduced.
What is Crypto-Mining via Phishing?
Cryptojacking is the covert installation of mining software on corporate equipment. Cybercriminals use computing power from your systems to mine cryptocurrency. For the company, this means:
-
Cost increase: Higher energy bills and IT capacity disappearing.
-
Productivity loss: Slow systems, employee and customer complaints.
-
Security risks: The same vulnerabilities can lead to data breaches.
In the Netherlands, this is often combined with phishing emails: realistic-looking emails that trick employees into clicking on a malicious link or attachment. Without training, employees often fail to recognize these signals.
How do you implement protection against cryptojacking?
Step 1: Risk analysis and phishing simulation
-
Conduct an industry-specific phishing test.
-
Identify vulnerable employees and departments.
-
Reporting and clear metrics for IT managers.
Step 2: Customized awareness training
-
Realistic scenarios tailored to your industry.
-
Practical tips for recognizing phishing emails.
-
Integration with AVG and NEN7510 compliance.
Step 3: Reporting and monitoring
-
Understanding click behavior and areas for improvement.
-
Dashboards for IT and management.
-
Progress made measurable quarterly.
Step 4: Continuous improvement
-
Regular simulations to keep alertness high.
-
Adaptation based on new attack techniques.
-
Culture shift: security becomes part of daily work.
Common mistakes among Dutch SMEs
-
One-time training: Without repetition, effectiveness drops within a few months.
-
No reporting: Without measurable results, understanding of risks is lacking.
-
IT-only focus: Employees outside the IT department are often forgotten.
-
No compliance link: AVG and NEN7510 require demonstrable awareness.
-
Reactive rather than proactive: Taking action only after an incident often costs more.
ALTA-ICT prevents this with a certified, ongoing awareness program and clear KPIs.
ROI of Security Awareness Training
On average, our customers see:
-
Up to 43% fewer incidents within 3 months.
-
Reduction in downtime due to fewer infected systems.
-
Demonstrated compliance with ISO27001, ISO9001 and NEN7510.
-
Higher employee satisfaction through a safer work environment.
For an SME, this can save tens of thousands of dollars – not to mention the reputational damage that is prevented.
