Attackers are running large ClickFix waves that lead users to โsupportโ pages and then walk them through self-executing steps. Because the victim performs the key action, automated defenses sometimes stand down. Consequently, threat actors steal Microsoft 365 credentials at scale, then pivot into mailbox rules, OAuth abuse, and session hijack. In parallel, several clusters drop stealers or remote access tools after the click.

The lure looks like a fix page for email, payments, or booking portals. It tells the user to copy a command, paste it into a console or browser dialog, and press Enter. Because the user triggers execution, filters that wait for drive-by exploits or unsanctioned downloads may not flag it. Therefore, defenders must watch behavioral context, not only file signatures.

Campaigns begin with phishing emails, malvertising, or compromised sites. The landing page coaches the target through โverificationโ or โrestore accessโ steps. After the user completes the action, kits harvest Microsoft 365 tokens or credentials; some runs also install payloads, including credential stealers and remote access tools. As signals age out, the same actors recycle the lure with minor text changes and fresh domains.

Recent waves impersonate Booking-style workflows to pressure hotel staff. Messages claim urgent guest changes or payment holds and direct managers to a ClickFix page. From there, credential theft leads to mailbox takeover and fraud against guests. In several cases, post-click malware like PureRAT appears in follow-on traffic, giving attackers a persistent foothold on staff endpoints.

Threat groups now use ClickFix generators that mass-produce lure pages. Some pages embed short tutorial videos that show users how to โfixโ the issue by pasting commands. Others test OS and browser to deliver tailored payloads. Because kits handle the steps, low-skill crews can run convincing campaigns at enterprise scale while rotating infrastructure.

Track referrer chains from email or ads into pages that instruct copy-and-paste actions. Alert when browsers or msedge.exe spawn shells (cmd, powershell) after visiting unknown domains. On Microsoft 365, monitor for suspicious OAuth consent, inbox rule creation, and token anomalies. Investigate new MFA-less logins, atypical device joins, or sudden mailbox forwarding to external addresses. To validate, follow the session: message โ landing โ user action โ token replay or payload drop.

Reduce human error paths. Enforce admin-approved app consent and restrict self-service OAuth. Require phishing-resistant MFA for staff with financial or booking privileges. Block scripted installs from browsers and deny command execution spawned by user-mode browsers. In email, quarantine messages that instruct users to paste commands or run scripts. Where possible, tune web proxies to flag pages that display step-by-step fix instructions. Finally, teach staff: support will never ask you to run a command.

Review ad and referral telemetry for ClickFix-style funnels. Block known kit domains and their short-lived look-alikes. On takeover cases, revoke refresh tokens, reset passwords, and audit inbox rules. Close the loop by scanning for PureRAT artifacts or other post-click payloads on any endpoint used by the compromised user. Afterwards, run a focused awareness sprint for front-desk and reservations teams.
ClickFix succeeds because it turns the user into the installer. As a result, it bypasses assumptions about what โmalware deliveryโ looks like. Tighten OAuth governance, force phishing-resistant MFA, and block browser-to-shell chains. If you treat instruction-driven lures as hostile by default, you shrink this techniqueโs success window.

Q: Why does ClickFix bypass some defenses?
A: The victim triggers the action, so systems tuned to block unsolicited downloads or exploitable bugs may not see a violation. Behavior-based policies close that gap.
Q: What blocks most ClickFix chains early?
A: Remove self-service OAuth consent for non-admin users, require phishing-resistant MFA, and prevent browsers from spawning shells or installers.
Q: How should hospitality teams validate suspected cases?
A: Check mailbox rules, recent OAuth consents, and sign-ins without MFA. Trace browser-spawned processes and scan for PureRAT or other stealers dropped post-click.
Q: Are malvertising paths common?
A: Yes. Actors rotate domains and ad content to reach targets beyond corporate email. Monitor referrals, not just inboxes.
Q: What user message stops the action?
A: โSupport will never ask you to paste a command or run a script to fix access.โ
