Is Linktree safe?
Linktree is a legitimate platform with standard security measures, but attackers exploit it to distribute phishing links. Because anyone can create a free Linktree account, cybercriminals set up profiles hosting credential-harvesting pages disguised as Microsoft 365 or other trusted services. The platform uses SSL encryption and monitors for abuse, but users must verify senders and preview destinations before clicking any Linktree link. Security researchers at Avanan documented attackers using Linktree's redirect feature to route victims to fake login pages that capture usernames and passwords.
How do attackers use Linktree for phishing?
Attackers create free Linktree profiles that host links to credential-harvesting sites. When a victim clicks a link on the malicious profile, they land on a phishing page that looks identical to a legitimate login portal. The fake page collects whatever credentials the victim enters and sends them directly to the attacker. This technique is part of the broader phishing-as-a-service trend where ready-made phishing kits make credential theft accessible to attackers with minimal technical skill.
Linktree's appeal to attackers is trust by association. Recipients see a legitimate Linktree domain in the URL and assume the destination is safe. The redirect obscures where the link actually leads. This same tactic appears across other link-in-bio platforms, URL shorteners, and open redirect vulnerabilities on major websites.
How to check if a Linktree link is safe
Verify three things before clicking any Linktree link: the sender's identity, the link destination, and whether the request makes sense. Most malicious Linktree links arrive by email, text, or direct message from an address impersonating a trusted source. On desktop, hover over the link to preview where it leads. If the Linktree profile then asks you to log in to Microsoft 365, a bank, or another service, stop. Legitimate businesses rarely route login requests through link-in-bio platforms.
- Check the sender address carefully. Attackers register domains that look similar to legitimate ones. A single character difference is easy to miss when scanning quickly.
- Hover before clicking. On a desktop browser, hover your mouse over the link to preview the destination URL. If the preview shows a domain you do not recognize or expect, do not click.
- Question unexpected requests. If a contact sends you a Linktree link out of the blue, confirm through a separate channel (phone call, different messaging app) before clicking. The verification mindset that pauses to confirm catches most social engineering attempts.
- Inspect the landing page URL. If you do click and reach a login page, check the URL in your browser's address bar. A legitimate Microsoft 365 login appears on login.microsoftonline.com, not a look-alike domain.
What to do if you clicked a suspicious Linktree link
If you entered credentials on a page you now suspect was fake, act within the first hour. Change your password immediately on the real service. If the compromised account uses the same password elsewhere, change those too. Enable or upgrade multi-factor authentication if you have not already. Note that attackers who capture session tokens can remain logged in even after a password change; your IT team may need to revoke active sessions to fully remove the intruder. Report the phishing page to Linktree and to your organization's IT or security contact.
What should SMB leaders ask their IT provider?
Business owners do not need to understand every phishing technique, but they should know whether their organization has defenses in place. Ask your IT lead or managed provider these questions:
- Do we have email filtering that flags suspicious links? Modern email security can detect and warn users about redirects through link-in-bio platforms when the final destination is known-bad or newly registered.
- Are employees trained on current phishing tactics? Generic annual training is not enough. Research-backed security awareness programs that run monthly simulations and provide immediate feedback reduce click rates more than annual compliance courses.
- How quickly can we revoke an account if credentials are stolen? Kits like Kali365 steal session tokens that survive password resets. Your response plan must include revoking active sessions, not just changing passwords.
- Have we reviewed OAuth apps connected to our Microsoft 365 or Google Workspace tenant? Third-party apps hold tokens that can be exploited. Most businesses have never audited the list.
