Experts Issue Warning About 'Unsubscribe' Links That Could Get You Hacked

It’s a button you’ve clicked a hundred times without a second thought: "Unsubscribe." But according to cybersecurity experts, clicking that familiar link might do more than clean up your inbox. It could make you a prime target for hackers.

A new warning, first reported by The Wall Street Journal, highlights just how risky it can be. Analysts at DNSFilter found that one in every 644 unsubscribe clicks redirects users to potentially malicious websites. That risk might sound small, but when your inbox is flooded with junk, the odds start stacking up fast.

"Once you click that link, you've left the safe, structured environment of your email client and entered the open web," said TK Keanini, CTO of DNSFilter. That's where things can go sideways.

Sometimes, the goal is simple: confirm your address is active. Just clicking tells attackers that you're a real person and that you're paying attention. From there, your address might be added to more spam lists or worse, targeted with social engineering scams.

Other risks are more aggressive. Fake unsubscribe links can lead to phishing sites or trigger malware downloads. 

If a page asks for your login credentials "to confirm your unsubscribe," experts say that’s a red flag. 

"Don’t do it," warns Michael Bargury, co-founder of Zenity. Instead, go directly to the brand's website to update your settings manually.

So what can you do instead? Use the "list-unsubscribe" button some email services display at the top of marketing emails. It's generally safer than links embedded in the body. Or just mark the message as spam and move on. Setting up filters or using disposable email addresses for signups can also cut down on future junk.

In the end, the best advice might be the simplest: if you don’t trust the sender, don’t trust their unsubscribe link. Because sometimes the clean-up comes with a cost you never saw coming.
