Why the Unsubscribe Link Isn’t Always Safe
The warning comes from TK Keanini, Chief Technology Officer at cybersecurity firm DNSFilter. Speaking recently to The Wall Street Journal, Keanini explained that unsubscribe links embedded in spam emails are increasingly being used by cybercriminals as a means of identifying active users and directing them to malicious websites.
Not Just Theoretical
The risks are not just theoretical. For example, DNSFilter estimates that roughly one in every 644 clicks on an unsubscribe link leads to a harmful destination. That may sound like a small percentage, but across the billions of marketing emails sent each day, the number of victims quickly adds up.
Unlike legitimate unsubscribe tools offered by trusted senders, these deceptive links don’t remove you from a list. Instead, they exploit your trust - by either redirecting you to phishing pages designed to steal your personal information, or by quietly logging your interaction to flag your email address as a ‘live’ target for further attacks.
