Analyzing these strings can help you identify suspicious users by detecting uncommon user-agent patterns or outdated browser versions frequently used by fraudsters.
• Track user behavior across multiple sessions: Keep a record of user activities, such as login attempts, page views, and conversion events, to better understand your typical user behavior. This information can be used to identify anomalies in user patterns and flag suspicious activities.

Strategy 2: Email Similarity Search

What is Email Similarity Search

Email Similarity Search is a technique used in fraud detection that helps identify potential phishing emails or attempts to spoof sender addresses. By doing so, it reduces the risk of unwanted email scams, helping protect your business and your customers alike.

How does it work

Email Similarity Search operates by examining patterns in email addresses and domain names. It looks for subtle changes or deviations from legitimate addresses, which cyber criminals often employ to deceive their targets. If the system spots any suspicious email patterns, it flags these as potentially malicious, alerting the recipient or the sender to exercise caution.

Pros & Cons

Pro: Reduces risk of falling for phishing attacks

By detecting slight alterations in email addresses or domain names, Email Similarity Search helps digital marketers safeguard themselves, their businesses, and their contacts from phishing attacks and spoofed sender addresses. This enhanced security provides a buffer against campaigns that could otherwise wreak havoc on your reputation, productivity, and resource allocation.
