Attackers are increasingly using the ClickFix technique to infect Windows computers to force users to run malicious scripts manually. The use of this tactic was first seen in the spring of 2024. Since then, attackers have come up with a number of scenarios for its use.

What is ClickFix?

The ClickFix technique is essentially an attempt to execute a malicious command on the victim’s computer relying solely on social engineering techniques. Under one pretext or another, attackers convince the user to copy a long command line (in the vast majority of cases — a PowerShell script), paste it into the system’s Run window, and press Enter, which should ultimately lead to compromising the system.

The attack normally begins with a pop-up window simulating a notification about a technical problem. To fix this problem, the user needs to perform a few simple steps, which boil down to copying some object and executing it through the Run application. However, in Windows 11, PowerShell can also be executed from the search bar for applications, settings, and documents, which opens when you click on the icon with the system’s logo, so sometimes the victim is asked to copy something there.

ClickFix attack – how to infect your own computer with malware in three easy steps. Source

This technique earned itself the name ClickFix because usually the notification contains a button, the name of which is somehow related to the verb “to fix” (Fix, How to fix, Fix it…), which the user needs to click to solve the alleged problem or see instructions for solving it. However, this isn’t a mandatory element — the need to launch some code can be justified by the requirement to check the computer’s security, or, for example, to confirm that the user is not a robot. In this case, the Fix button can be omitted.

An example of instructions for confirming that you’re not a robot. Source

The scheme may differ slightly from case to case, but attackers typically give the victim the following instructions:

• click the button to copy the code that solves the problem;
• press the key combination [Win] + [R];
• press the combination [Ctrl] + [V];
• press [Enter].

So what actually happens? The first action (clicking the button to copy the code that solves the problem) copies some script invisible to the user to the clipboard. The second (pressing the key combination [Win] + [R]) opens the Run window, which in Windows is designed to quickly launch programs, open files and folders, and enter commands. In the third (pressing the combination [Ctrl] + [V]), the PowerShell script is pasted into Run window from the clipboard. And finally, with the fourth action (pressing [Enter]), the code is launched with the current user privileges.

As a result of executing the script, malware is downloaded and installed onto the computer — with the specific malicious payload varying from campaign to campaign. Thus, what we get is the user running a malicious script on their own system thereby infecting his own computer.

Typical attacks using the ClickFix technique

Sometimes attackers create their own websites and lure users to them using various tricks. Or they hack existing websites and force them to display a pop-up window with instructions. In other cases similar instructions are delivered under various pretexts via email, social networks, or even through instant-messengers. Here are some typical scenarios of using this technique in attacks:

1. Unable to display the page, need to refresh the browser

A classic scenario in which the visitor doesn’t see the page they expected to and is told they need to install a browser update to display it.

2. Error loading a document on a website

Another standard tactic: the user isn’t allowed to view a certain document in Microsoft Word or PDF format. Instead, they’re shown a notification asking to install a plugin for viewing the PDF or “Word online”.

3. Error opening a document from email

In this case attackers substitute the file format. The victim sees a .pdf or .docx icon, but in reality clicks on the HTML file that opens in the browser. Then everything is similar to the previous case — what are needed are: a plugin, malicious instructions, and the familiar “How to fix” button.

4. Problems with the microphone and camera in Google Meet or Zoom

A more unusual variation of the ClickFix tactic is used on fake Google Meet or Zoom websites. The user receives a link for a video call, but “is not allowed to join” it, because there are problems with their microphone and camera. The message “explains” how to fix it.

5. Prove that you’re not a robot – fake CAPTCHA

Finally, the most curious version of the attack using ClickFix: the site visitor is asked to complete a fake CAPTCHA to prove they’re not a robot. But the required proof is, of course, is to follow the instructions written in the pop-up window.

Prove you’re not a robot – to do this, run a malicious script on your computer. Source

How to protect yourself from ClickFix attacks?

The simplest mechanism for protecting your company from attacks using the ClickFix technique involves blocking the [Win] + [R] key combination in the system — it’s hardly needed at all in the day-to-day work of the typical employee. However, this isn’t a panacea — as we already wrote above, in Windows 11 the script can be launched from the search bar, and some variations of this attack use more detailed instructions in which the user is told how to manually open the Run window.

Therefore, protective measures, of course, should be comprehensive and primarily aimed at training employees. It’s worth conveying to them that if someone seeks any manual manipulations with the system — it’s an extremely alarming sign.

Here are some tips on how to protect your organization’s employees from attacks using ClickFix tactics:

• Be sure to use a reliable security solution on all corporate devices, and also install protection at the mail gateway level.
• Raise employee awareness of cyberthreats, including new tactics, with specialized training. Organizing such training is easy – just use our automated educational Kaspersky Automated Security Awareness Platform .

2024 wasn’t the year that AI rewrote the cybercrime playbook — but it did turbocharge some of the old tricks. In Cisco Talos’ 2024 Year in Review, with the help of our friends at Robust Intelligence (now a Cisco company), we dissect how cybercriminals used generative AI to scale up social engineering, fine-tune phishing, and automate grunt work like OSINT gathering.

So while AI didn’t completely rock the threat landscape last year, the groundwork is being laid for 2025, where agentic AI and automated vulnerability hunting could cause some significant challenges for defenders. Our research showcases the top four areas of concern for the coming year.

Curious about how AI could impact your defenses — or your data — this year? Take a look at this summary of AI-based threats:

Phishing attacks spiked this quarter as threat actors leveraged this method of initial access in half of all engagements, a vast increase from previous quarters. Conversely, the use of valid accounts for initial access was rarely seen this quarter, despite being the top observed method in 2024, according to our Year in Review report. Nevertheless, valid accounts played a prominent role in the attack chains Cisco Talos Incident Response (Talos IR) observed as actors predominately used phishing to gain access to a user account, then leveraged this access to establish persistence in targeted networks.

Ransomware and pre-ransomware incidents made up a slightly larger portion of threats observed this quarter, with most incidents falling into the latter category. Talos IR’s investigations into pre-ransomware events provided unique insight into defensive measures that successfully stopped these attacks before a ransomware executable could be deployed, including early engagement with the incident response team and robust monitoring of certain threat actor tactics, techniques and procedures (TTPs).

Actors leverage access to valid accounts via phishing to establish persistence

Threat actors used phishing to achieve initial access in 50 percent of engagements, a notable increase from less than 10 percent last quarter. Vishing was the most common type of phishing attack seen, accounting for over 60 percent of all phishing engagements, though we also observed malicious attachment, malicious link and business email compromise (BEC) attacks.

Adversaries predominately leveraged phishing to gain access to a valid account, pivot deeper into the targeted network, and expand their foothold, contrasting other phishing objectives we have seen in the past such as eliciting sensitive information or monetary transfers. For example, in an observed vishing campaign — described in further detail in the ransomware section below — adversaries deceived users over the phone into establishing remote access sessions to the user’s workstation, then used this access to load tooling, establish persistence mechanisms and disable endpoint protections.

In some engagements, actors leveraged phishing attacks to steal users’ legitimate access tokens, enabling them to maintain persistent access to the targeted networks. In one engagement, adversaries deployed a phishing email with a malicious link to successfully steal a user’s multi-factor authentication (MFA) session token along with their credentials. From there, the actors gained unauthorized access to the target’s Microsoft Office 365 environment and deployed enterprise applications with the likely goal of gaining further access into additional accounts. In another phishing engagement, upon gaining access to a user’s valid account, the actors cloned their active access token and specified new credentials for outbound connections. They then sought to expand their access by running commands to gather system information and creating a scheduled task to execute a malicious JavaScript file upon user login.

Ransomware trends

Vishing campaign leveraging BlackBasta and Cactus TTPs hits manufacturing and construction organizations 

Ransomware and pre-ransomware incidents made up over 50 percent of engagements this quarter, an increase from nearly 30 last quarter. A robust campaign leveraging BlackBasta and Cactus TTPs that targeted manufacturing and construction organizations accounted for over 60 percent of pre-ransomware and ransomware engagements and was consistent with public reporting on likely related incidents.  

The attack chain we observed begins with the threat actors flooding users’ mailboxes at targeted organizations with a large volume of benign spam emails. After a few days, the actors call the victim, usually via Microsoft Teams, and direct them to initiate a Microsoft Quick Assist remote access session, helping them with installation of the program if not already present on the user’s system. Once a Quick Assist session is established, the adversary loads tooling to collect information about the target system and establish persistence. The actors create the TitanPlus registry key and embed IP addresses to enable command and control (C2) communication, using character substitution to obfuscate the infrastructure. After completing the TitanPlus registry key persistence process, the adversary then performs subsequent privilege escalation and lateral movement, seemingly with the ultimate goal of deploying ransomware. We initially observed the threat actors leveraging BlackBasta ransomware and pivoting to Cactus ransomware after public reporting on their use of the former was released. Our analysis of engagements involving Cactus led us to identify a previously undocumented variant of the ransomware, which builds upon previous functionality with new command-line arguments that provide the threat actors with greater control over the binary’s function, likely to prioritize efficiency and maximum impact.

Looking forward: The threat actors responsible for this campaign have proven to be agile, modifying their TTPs as more public reporting on this campaign emerges, which leads us to assess they will continue to adjust their TTPs and/or incorporate a different ransomware family or tooling into their attack chain moving forward to evade detection. We published our findings on this campaign in our Year in Review report in late March 2025 and will be tracking this activity to see if the threat actors modify their operations moving forward.

Early detection of pre-ransomware TTPs halts attacks before encryption

Out of all ransomware and pre-ransomware engagements this quarter, 75 percent of incidents fell into the latter category, providing insight into defensive measures that successfully stopped these attacks before a ransomware executable could be deployed.

One tactic that proved effective was early engagement with the incident response team. For example, in one engagement, Talos IR was contacted directly after the organization’s users experienced a flood of spam email. Given this TTP was consistent with the vishing campaign we had already observed affecting other organizations, we were able to advise that this was very likely pre-ransomware activity and share actionable indicators of compromise (IOCs) and mitigation recommendations.    

Another defensive measure that was effective in containing pre-ransomware activity was robust monitoring and endpoint detection and response (EDR) solutions, particularly those configured to alert on unauthorized remote access connections and suspicious file execution. In one engagement, Cisco XDR was configured to flag certain TTPs that the security team identified were consistent with pre-ransomware activity, and soon after the alerts were triggered, they moved quickly to focus on eradication of the threat. The TTPs included use of remote access tools, disabling of the volume shadow copy service (VSS), and use of a local account to deploy a vulnerable driver. In another engagement, the organization’s monitoring tools alerted them of unauthorized remote access and they acted swiftly to respond to the affected system, resulting in the threat actor only having access to the targeted system for three minutes. In a different incident, suspicious file execution was flagged, leading the customer to identify the threat and isolate the system within hours of initial access.

Crytox becomes latest ransomware group to leverage HRSword to disable EDR protections

Crytox appeared in a Talos IR engagement for the first time this quarter, with affiliates leveraging HRSword as part of their attack chain — a tool that has not previously been publicly associated with the ransomware group. According to public reporting, Crytox is a ransomware family first seen in 2020 that typically encrypts local disks and network drives and drops a ransom note with a five-day ultimatum. Affiliates are known to leverage the uTox messenger application so victims can communicate with the threat actors. 

Talos IR responded to an engagement in which adversaries exploited a public-facing application that was not protected by MFA to gain initial access, then launched a ransomware attack that encrypted two hypervisors hosting numerous VM servers. The actors used TTPs that aligned with known Crytox TTPs, including using uTox for communication and dropping a ransomware note that matches publicly shared Crytox ransom notes. Of note, we also observed the affiliates using HRSword to disable the target’s EDR solution. We first reported on ransomware actors’ use of HRSword in FY24 Q1, specifically highlighting a Phobos incident, and observed additional threat groups leverage the tool throughout the remainder of the year.

Targeting

The manufacturing industry vertical was the most affected this quarter, accounting for 25 percent of engagements. Notably, though education was the most targeted vertical for the second half of 2024, we did not respond to any incidents targeting education entities this quarter.

Initial access

As mentioned, the most observed means of gaining initial access this quarter was phishing, followed by use of valid accounts and exploitation of public facing applications. The increase in phishing attacks this quarter is likely due in part to the robust vishing campaign we observed that accounted for over 60 percent of all phishing engagements.

Recommendations for addressing top security weaknesses 

Implement properly configured MFA and other access control solutions

Half of the engagements this quarter involved MFA issues, including misconfigured MFA, lack of MFA and MFA bypass. As mentioned in the above ransomware section, token theft played a role in several incidents this quarter, enabling threat actors to bypass authentication controls and establish trusted connections. We also observed threat actors adding malicious secondary MFA devices to compromised accounts as well as taking advantage of a lack of MFA on remote access services, the latter of which is a tactic we have consistently observed in previous quarters. Talos IR recommends monitoring and alerting on the following for effective MFA deployment: abuse of bypass codes, creation of accounts designed to bypass or be exempt from MFA and removal of accounts from MFA.

Enforce user education on phishing and social engineering attacks

Half of the engagements this quarter involved social engineering, potentially highlighting insufficient user education. This security weakness corresponds with the surge in phishing attacks, as users were manipulated to grant attackers access to their environments, with vishing proving to be particularly effective. Talos IR recommends raising awareness of phishing and social engineering techniques, as user education is a key part of spotting phishing attempts, countering MFA bypass techniques and knowing where to report suspicious activity.

Protect endpoint security solutions

Almost 20 percent of incidents involved organizations that did not have protections in place to prevent uninstallation of EDR solutions, enabling actors to disable these defenses. Talos IR strongly recommends ensuring endpoint solutions are protected with an agent or connector password and customizing their configurations beyond the default settings. Additional recommendations for hardening EDR solutions against this threat can be found in our 2024 Year in Review report.

Top-observed MITRE ATT&CK techniques

The table below represents the MITRE ATT&CK techniques observed in this quarter’s Talos IR engagement. Given that some techniques can fall under multiple tactics, we grouped them under the most relevant tactic in which they were leveraged. Please note this is not an exhaustive list.

Key findings from the MITRE ATT&CK framework include:  

• This was the first quarter since January to March of 2024 (Q1 FY24) in which phishing was the top initial access technique, with actors leveraging vishing, malicious links, malicious attachments and BEC attacks.   
• We observed actors leveraging a wider variety of commercial and open-source remote access tools this quarter, including SplashTop, Atera, TeamViewer, AnyDesk, LogMeIn, ScreenConnect, QuickAssist, TightVNC and Level’s RMM platform. These tools appeared in 50 percent of engagements, a slight increase from almost 40 percent last quarter.

The familiar checkout ritual at the supermarket: once everything’s been scanned — the offer, delivered with a hopeful smile: “Chocolate bar for the road? It’s a good one, and the discount is almost criminal”. If you’re lucky, you get a delicious bonus at a great price. But more often than not they’re trying to sell you something that’s not selling well: either it’s about to expire or it has some other hidden flaw.

Now, imagine you declined that chocolate bar, but it was secretly slipped into your bag anyway, or even worse, into your pocket, where it melted and ruined your clothes, spoiling your day. Well, something similar happened to those who bought knock-offs of popular smartphone brands from online marketplaces. No, they didn’t get a chocolate bar. They walked away with a brand-new smartphone that had the Triada Trojan embedded in its firmware. This is much worse than melted chocolate. Their crypto balances, along with their Telegram, WhatsApp, and social media accounts, could be gone before they could utter “bargain!”. Someone could steal their text messages and a lot more.

Triada? What Triada?

That’s the name we at Kaspersky gave to the Trojan we first discovered and described in detail in 2016. This mobile malware would infiltrate almost every process running on a device, while residing only in the RAM.

The emergence of Triada spelled a new era in the evolution of mobile threats targeting Android. Before Triada, Trojans were relatively harmless — mainly displaying ads and downloading other Trojans. This new threat showed that things would never be the same again.

With time, Android developers fixed the vulnerabilities that early versions of Triada exploited. Recent Android versions restricted even users with root privileges from editing system partitions. Did this stop the cybercriminals? What do you think?!..

Fast-forward to March 2025, and we discovered an adapted version of Triada that takes advantage of the new restrictions. The threat actor infects the firmware even before the smartphones are sold. Pre-installed in system partitions, the malware proves nearly impossible to remove.

What is this new version capable of?

Our Android security solution detects the new version of Triada as Backdoor.AndroidOS.Triada.z. This new version is what’s embedded in the firmware of fake Android smartphones available from online marketplaces. It can attack any application running on the device. This gives the Trojan virtually unlimited capabilities. It can control text messages and calls, steal crypto, download and run other applications, replace links in browsers, surreptitiously send messages in chat apps on your behalf, and hijack social media accounts.

A copy of Triada infiltrates every app launched on an infected device. Besides that, the Trojan includes specialized modules that target popular apps. As soon as the user downloads a legitimate app like Telegram or TikTok, the Trojan embeds itself in it and starts causing harm.

Telegram. Triada downloads two modules to compromise Telegram. The first one initiates malicious activity once a day, connecting to a command-and-control (C2) server. It sends the victim’s phone number to the criminals, along with complete authentication data — including the access token. The second module filters all messages, interacting with a bot (which didn’t exist at the time of our research), and deleting notifications about new Telegram logins.

Instagram. Once a day, the Trojan runs a malicious task to search for active session cookies and forward the data to the attackers. These files help the criminals assume full control over the account.

Browsers. Triada threatens a number of browsers: Chrome, Opera, Mozilla, and some others. The full list is available in the Securelist article. The module connects to the C2 server over TCP and randomly redirects legitimate links in the browsers to advertising sites for now. However, because the Trojan downloads redirect links from its C2 server, attackers can direct users to phishing sites at any time.

WhatsApp. Again, there are two modules. The first one collects and sends data about the active session to the C2 server every five minutes — giving the attackers full access to the victim’s account. The second one intercepts the client functions for sending and receiving messages, which allows the malware to send and then delete arbitrary instant messages to cover its tracks.

LINE. The dedicated Triada module collects internal app data, including authentication data (access token), every 30 seconds, and forwards it the C2 server. In this case, too, someone else assumes full control of the user’s account.

Skype. Although Skype is about to be retired, Triada still has a module for infecting it. Triada uses several methods to obtain the authentication token and then sends it to the C2 server.

TikTok. This module can collect a lot of data about the victim’s account from cookie files in the internal directory, and also extract data required for communicating with the TikTok API.

Facebook. Triada is armed with two modules for this app. One of them steals authentication cookies, and the other sends information about the infected device to the C2 server.

Of course, there are also modules for SMS and calls. The first SMS module allows the malware to filter all incoming messages and extract codes from them, respond to some messages (likely to subscribe victims to paid services) and send arbitrary SMS messages when instructed by the C2 server. The second, auxiliary module disables the built-in Android protection against SMS Trojans that requests user permission before sending messages to short codes (Premium SMS), which could be used to confirm paid subscriptions.

The call module embeds itself in the phone app, but it’s most likely still under development. We discovered that it partially implements phone number spoofing — something we expect to be completed soon.

Another module, a reverse proxy, turns the victim’s smartphone into a reverse proxy server, giving attackers access to arbitrary IP addresses on behalf of the victim.

Not unexpectedly, Triada also targets crypto owners, with a special surprise awaiting them: a clipper. The Trojan watches the clipboard for crypto wallet addresses, substituting one of the attackers’ own. A crypto stealer analyzes the victim’s activity, replacing crypto wallet addresses with a fraudulent addresses anywhere it can, whenever an attempt is made to withdraw cryptocurrency. It even interferes with button tap handlers inside apps and replaces images with generated QR codes that link to the attackers’ wallet addresses. The criminals have managed to steal more than US$264 000 in various cryptocurrencies since June 13, 2024 with the help of these tools.

See our Securelist report for a full list of Triada features and a detailed technical analysis.

How the malware infiltrates smartphones.

In every infection case that we are aware of, the firmware name on the device differed from the official one by a single letter. For example, the official firmware was TGPMIXM, while the infected phones had TGPMIXN. We found posts on relevant discussion boards where users complained about counterfeit devices purchased from online stores.

It’s likely that a stage in the supply chain was compromised, while the stores had no idea they were distributing devices infected with Triada. Meanwhile, it’s practically impossible to determine exactly when the malware was placed inside the smartphones.

How to protect yourself from Triada

The new version of the Trojan was found pre-installed on counterfeit devices. Therefore, the best way to avoid Triada infection is to buy smartphones from authorized dealers only. If you suspect that your phone may have been infected with Triada (or another Trojan), here are our recommendations.

• Refrain from using any of the potentially compromised apps listed above or making any financial transactions — including cryptocurrency.
• Install Kaspersky for Android on your smartphone to check if it’s indeed infected.
• If Triada is found on the device, reflash the smartphone with the official firmware yourself, or contact the local service center. Expect sudden changes to your smartphone’s specs: besides the pre-installed Trojan, the fake firmware often overstated the RAM and storage.
• If your smartphone is found to be infected with Triada, check all messaging and social media apps that may have been compromised. For chat apps, make sure you terminate any sessions still running on devices you don’t recognize, and check your privacy settings according to our guide WhatsApp and Telegram account hijacking: How to protect yourself against scams. If you suspect that your instant messaging accounts have been hijacked, read What to do if your WhatsApp account gets hacked or What to do if your Telegram account is hacked. Terminate all social media sessions on all your devices and change your passwords. Kaspersky Password Manager can help you with that.
• Our Privacy Checker portal offers a step-by-step guide on configuring privacy in various applications and operating systems in general.
