A number of recent public data breaches have been linked to ClickFix-style TTPs, such as Kettering Health, DaVita, City of St. Paul, Minnesota, and the Texas Tech University Health Sciences Centers (with many more breaches likely to involve ClickFix where the attack vector wasn’t known or disclosed).\\n\\nBut why are these attacks proving to be so effective? \\n\\n## **Reason 1: Users aren’t ready for ClickFix**\\n\\nFor the past decade or more, user awareness has focused on stopping users from clicking links in suspicious emails, downloading risky files, and entering their username and password into random websites. It hasn’t focused on opening up a program and running a command. \\n\\nSuspicion is further reduced when you consider that the malicious clipboard copy action is performed behind the scenes via JavaScript 99% of the time. \\n\\n \\n— \\nExample of unobfuscated JavaScript code performing the copy function automatically on a ClickFix page without user input. \\n \\nAnd with modern ClickFix sites and lures becoming increasingly legitimate-looking (see the example below), it’s not surprising that users are falling victim. \\n\\n \\n— \\nOne of the more legit-looking ClickFix lures \u2014 this one even has an embedded video showing the user what to do! \\n \\nWhen you consider the fact that these attacks are moving away from email altogether, it doesn’t fit the model of what users are trained to be suspicious of. \\n\\nThe top delivery vector identified by Push Security researchers was found to be **SEO poisoning** \\u0026 **malvertising** via Google Search. By creating new domains or taking over legitimate ones, attackers are creating watering hole scenarios to intercept users browsing the internet. \\n\\nAnd even if you were suspicious, there’s no convenient \\”report phishing\\” button or workflow to notify your security team for Google Search results, social media messages, website ads, and so on. \\n\\n## **Reason 2: ClickFix isn’t being detected during delivery**\\n\\nThere are a few aspects of why ClickFix attacks are going undetected by technical controls.\\n\\nClickFix pages, like other modern phishing sites, are using a range of detection evasion techniques that prevent them from being flagged by security tools \u2014 from email scanners, to web-crawling security tools, to web proxies analyzing network traffic. Detection evasion mainly involves camouflaging and rotating domains to stay ahead of known-bad detections (i.e., blocklists), using bot protection to prevent analysis, and heavily obfuscating page content to stop detection signatures from firing. \\n\\nAnd by using non-email delivery vectors, an entire layer of detection opportunity is cut out. \\n\\n \\n— \\nLike other modern phishing attacks, ClickFix lures are distributed all over the internet \u2014 not just email. \\n \\nMalvertising adds another layer of targeting to the picture. For example, Google Ads can be targeted to searches coming from specific geographic locations, tailored to specific email domain matches, or specific device types (e.g. desktop, mobile, etc.). If you know where your target is located, you can tailor the ad parameters accordingly. \\n\\nAlong with other techniques, like conditional loading to return a lure appropriate for your operating system (or not triggering at all unless certain conditions are met, e.g. you’re visiting from a mobile OS, or from outside a target IP range) attackers have a way of reaching a large number of potential victims while avoiding security controls at the email layer and preventing unwanted analysis. \\n\\n \\n— \\nExample of a ClickFix lure built onto a vibe-coded site. \\n \\nFinally, because the code is copied inside the browser sandbox, typical security tools are unable to observe and flag this action as potentially malicious. This means that the last \u2014 and only \u2014 opportunity for organizations to stop ClickFix is on the endpoint, after the user has attempted to run the malicious code.\\n\\n## **Reason 3: EDR is the last and only line of defense \u2014 and it’s not foolproof**\\n\\nThere are multiple stages to the attack that can and should be intercepted by EDR, but the level of detection raised, and whether an action is blocked in real time, is driven by context. \\n\\nBecause there’s no file download from the web, and the act of running code on the machine is initiated by the user, there’s no context tying the action to another application to make it appear suspicious. For example, malicious PowerShell executed from Outlook or Chrome would appear obviously suspicious, but because it’s user-initiated, it’s isolated from the context of where the code was delivered. \\n\\nThe malicious commands themselves might be obfuscated or broken into stages to avoid easy detection by heuristic rules. EDR telemetry might record that a PowerShell process ran, but without a known bad signature or a clear policy violation, it may not flag it immediately.\\n\\nThe final stage at which the attack should be intercepted by any reputable EDR is at the point of malware execution. But detection evasion is a cat-and-mouse game, and attackers are always looking for ways to tweak their malware to evade or disable detection tools. So, exceptions do happen. \\n\\nAnd if you’re an organization that allows employees and contractors to use unmanaged BYOD devices, there’s a strong chance that there are gaps in your EDR coverage.\\n\\nUltimately, organizations are leaving themselves relying on a single line of defense \u2014 if the attack isn’t detected and blocked by EDR, it isn’t spotted at all. \\n\\n## **Why the standard recommendations are falling short**\\n\\nMost of the vendor-agnostic recommendations have focused on restricting access to services like the Windows Run dialog box for typical users. But although mshta and PowerShell remain the most commonly observed, security researchers have already spotted a wide range of LOLBINS targeting different services, many of which are difficult to prevent users from accessing. \\n\\nIt’s also worth considering how ClickFix-style attacks may continue to evolve in the future. The current attack path straddles browser and endpoint \u2014 what if it could take place entirely in the browser and evade EDR altogether? For example, by pasting malicious JavaScript directly into the devtools on a relevant webpage.\\n\\n \\n— \\nThe current hybrid attack path sees the attacker deliver lures in the browser, to compromise the endpoint, to get access to creds and cookies stored in the browser. What if you could skip the endpoint altogether? \\n \\n## **Stopping ClickFix on the front line \u2014 in the browser**\\n\\nPush Security’s latest feature, malicious copy and paste detection, tackles ClickFix-style attacks at the earliest opportunity through browser-based detection and blocking. This is a universally effective control that works regardless of the lure delivery channel, page style and structure, or the specifics of the malware type and execution.\\n\\nUnlike heavy-handed DLP solutions that block copy-paste altogether, Push protects your employees without disrupting their user experience or hampering productivity.\\n\\nCheck out the video below for more information.\\n\\n## **Learn more**\\n\\nIf you want to learn more about ClickFix attacks and how they’re evolving, check out this upcoming webinar where Push Security researchers will be diving into real-world ClickFix examples and demonstrating how ClickFix sites work under the hood. \\n\\n\\n\\nPush Security’s browser-based security platform provides comprehensive attack detection and response capabilities against techniques like AiTM phishing, credential stuffing, ClickFixing, malicious browser extensions, and session hijacking using stolen session tokens. You can also use Push to find and fix vulnerabilities across the apps that your employees use, like ghost logins, SSO coverage gaps, MFA gaps, vulnerable passwords, risky OAuth integrations, and more, to harden your identity attack surface.\\n\\nTo learn more about Push, check out our latest product overview or book some time with one of our team for a live demo.\\n\\nFound this article interesting?
