  • Unsecured APIs -Exploiting vulnerabilities in APIs to access sensitive data.
  • Insider Threats - Employees misusing or leaking information, either maliciously or unintentionally.

2. Phishing Attacks

Phishing remains a prevalent threat, with attackers using deceptive methods to extract sensitive information. These attacks typically involve:
  • Email Scams -Fraudulent emails impersonating legitimate organizations.
  • Smishing -Phishing via SMS, where attackers send text messages to lure victims.
  • Spear Phishing - Targeted phishing attacks aimed at specific individuals or companies.
  • Vishing - Voice phishing, using phone calls to extract personal details.
FinTech firms counteract this by educating users on spotting phishing attempts and implementing multi-factor authentication for added security. Advanced email filtering systems and updated security protocols are critical in thwarting these attacks.

3. Insider Threats

Insider threats arise from employees or partners misusing their access to sensitive data.
This includes:
  • Malicious Insiders -Employees deliberately causing harm through data theft or sabotage.
  • Negligent Insiders - Staff inadvertently compromising security through careless actions.
  • Credential Theft -Attackers gaining access to insider credentials and masquerading as legitimate users.
FinTech companies are mitigating this risk through strict access controls and regular monitoring of employee activities. Promoting a culture of cybersecurity awareness and adherence to ethical guidelines is crucial in minimizing these incidents.

4. DDoS Attacks

Distributed Denial of Service (DDoS) attacks disrupt FinTech services by overwhelming systems with traffic.
These attacks involve:
  • Network Flooding - Overloading the network with an excessive amount of traffic.
  • Application Layer Attacks - Targeting specific aspects of an application or service.
  • Multi-Vector Attacks -Combining different attack methods to overwhelm systems.
