Emergence of the ClickFix Technique
A New Phishing Methodology
The ClickFix technique represents a novel social engineering approach that preys on user behavior, combining deception with a realistic and trustworthy front to exploit the hospitality sector’s reliance on Booking.com for reservations and communication. Unlike traditional phishing methods, ClickFix manipulates victims into believing they are addressing a non-existent error, thereby tricking them into executing harmful commands. The primary mechanism involves directing users to counterfeit CAPTCHA verification pages that elaborate on the necessity of specific actions, creating a false sense of urgency and legitimacy.
This sophisticated phishing technique bypasses many automated security defenses by shifting the burden of malware execution onto unwitting users. The process begins with a simple email that purports to be from Booking.com, referencing a negative review that demands immediate attention. This email contains either a link or a PDF attachment linking the recipient to a seemingly legitimate CAPTCHA verification page. The fake CAPTCHA verification page instructs users to initiate specific commands via the Windows Run window, effectively triggering the malware deployment process in a variety of ways tailored to evading detection.

Anatomy of a ClickFix Phishing Attack
The Phishing Sequence
In a typical ClickFix phishing scenario, attackers initiate their scams by sending fraudulent emails to targeted individuals within the hospitality sector. These emails are meticulously crafted to resemble legitimate correspondence from Booking.com, complete with realistic branding and urgent messaging. The subject matter often references a negative review purportedly left by a guest, prompting the recipient to take immediate action to resolve the issue. This sense of urgency increases the likelihood of the victim following through with the subsequent steps without suspicion.
The email contains either a hyperlink or an attached PDF that claims to lead the recipient to the Booking.com site for further action. However, this link redirects them to a counterfeit CAPTCHA verification page designed to mimic a legitimate Booking.com page closely. The purpose of this phony verification page is to create an appearance of legitimacy, lulling the target into a false sense of security while masking the malicious intent behind the attack. This method’s success hinges on its ability to exploit the target’s familiarity with and trust in Booking.com.
Execution of the ClickFix Technique
The deceptive CAPTCHA page is the crux of the ClickFix tactic, as it instructs the user to execute specific commands that initiate the malware deployment process. Once on the counterfeit CAPTCHA page, the user sees seemingly innocuous instructions to open a Windows Run window using a keyboard shortcut. They are then directed to paste and execute a command from the webpage, believing it is necessary to solve the non-existent issue. This command utilizes the legitimate mshta.exe binary—a trusted Windows process—to drop the next-stage payload, thus bypassing several security protocols that typically flag unknown or suspicious executables.
The payload delivered by this process includes a variety of malware families designed to steal credentials and commit other malicious activities. These can include XWorm, Lumma Stealer, VenomRAT, AsyncRAT, Danabot, and NetSupport RAT. Each malware type has a specific function, primarily centered around data extraction and unauthorized access, causing significant damage to the victim’s operational integrity and financial resources. The careful orchestration of this task chain makes it exceedingly difficult for standard security measures to detect and mitigate the threat before substantial harm is done.
