Fraudulent, malicious, and suspicious IP addresses are among the biggest cyber threats facing businesses today. Whether you’re protecting against phishing, bot attacks, or risky IPs, FraudGuard.io offers powerful tools to assess IP reputation, check fraud risks, and safeguard your operations.

This guide will walk you through the process of detecting fraudulent and malicious IPs using FraudGuard.io—step-by-step.

What Is an IP Lookup Tool?

An IP lookup tool uncovers essential information about an IP address, including:

  • Geographic location: Identify where the IP is registered.
  • Internet Service Provider (ISP): Determine the provider linked to the IP.
  • Risk level: Evaluate the IP’s likelihood of malicious or suspicious activity.

FraudGuard.io takes this further by offering IP reputation analysis to help businesses:

  • Assess IP fraud risks using advanced scoring systems.
  • Detect risky IPs linked to fraud, spam, abuse, etc.
  • Access real-time fraud checks via API integration.

Why It’s Important to Check Fraudulent and Malicious IPs

Fraudulent and malicious IPs can harm your business in many ways:

1. Cyber Threats

Hackers use risky IPs to exploit systems via phishing schemes, malware, and DDoS attacks.

2. Digital Fraud

Fraudulent IPs are linked to:

  • Chargeback fraud and stolen credit card usage.
  • Account takeovers using breached credentials.

3. Network Abuse

Spammers and bots exploit suspicious IPs to overload systems with fake traffic.

4. IP Reputation Damage

IP addresses flagged for abuse can harm your domain reputation, impacting deliverability and SEO performance.

5. Analyze the Results

When you submit an IP address, FraudGuard.io provides comprehensive insights to help you assess potential threats:

  • Risk Levels:
    Each IP is assigned a risk level from 1 to 5, indicating the severity of potential threats:

    • Level 1 (Low Risk): IP addresses with minimal or negligible threats, typically maintaining a clean reputation and unlikely to be involved in malicious activities.

    • Level 2: IP addresses that may exhibit some indicators of suspicious behavior but are not deemed highly risky. 2FA verification/monitoring for unusual activity is advisable.

    • Level 3 (Moderate Risk): IP addresses demonstrating suspicious or potentially harmful behaviors; exercise caution and implement security measures. 2FA verification/monitoring for unusual activity is advisable.

    • Level 4 (High Risk): IP addresses with significant indications of malicious activities; consider implementing restrictions to mitigate threats; these should be blocked.

    • Level 5 (Critical Risk): IP addresses carrying the highest level of risk, often linked to coordinated or highly malicious activities; these should be blocked.

  • Threat Classifications:
    FraudGuard.io categorizes IP addresses based on their associated activities, offering insights into potential threats:

    • Anonymous Tracker: IPs linked to anonymization services like VPNs, proxies, or Tor nodes, which could obscure the true origin of traffic and pose risks.

    • Botnet Tracker: IPs detected as part of botnets, which are networks of compromised devices often used for coordinated attacks, spam, or malware distribution.

    • Honeypot Tracker: IPs identified by FraudGuard.io’s honeypots, which detect malicious activity targeting decoy systems to uncover new threats.

    • Abuse Tracker: IPs associated with abusive behaviors like phishing, spamming, or brute-force login attempts.

    • Spam Tracker: IPs flagged for spamming activities, often involved in sending unsolicited or harmful emails.

    • VPN Tracker: IPs associated with known VPN servers, which may be used to mask malicious activities or evade geo-restrictions. While not inherently malicious, these IPs warrant closer scrutiny, especially in cases of fraud or account takeovers.

This granular analysis helps you assess whether an IP is trustworthy, flagged for abuse, or involved in malicious activity. By understanding the risk levels and threat classifications, you can take precise actions to secure your systems.
