A new Rust-based infostealer, EDDIESTEALER, is being spread using the ClickFix social engineering technique, according to a report by Elastic Security Labs on May 30, 2025. This method leverages fake CAPTCHA prompts on compromised websites. Users are tricked into copying and pasting a PowerShell command into their Windows terminal, believing they are verifying they aren't a robot. This command then downloads and executes a malicious JavaScript file, gverify.js, which in turn retrieves the final EDDIESTEALER payload.
The EDDIESTEALER malware is designed to steal sensitive information from infected hosts. Written in Rust, it avoids static analysis through various obfuscation techniques, including XOR string encryption and stripping of function symbols. The malware dynamically retrieves a task list from the attacker's command-and-control (C2) server, enabling it to adapt its behavior over time. Elastic Security Labs has observed it targeting a range of cryptocurrency wallets, web browsers, password managers, FTP clients, and the Telegram messaging app. EDDIESTEALER also employs several evasion techniques, including a basic anti-sandbox check, a self-deletion mechanism, and a custom Windows API lookup method to avoid static analysis of its API interactions. The dynamic C2 tasking method allows attackers to update the list of targeted apps as needed, providing greater flexibility and adaptability. Security experts emphasize the continued popularity of the ClickFix social engineering method and the increasing use of the Rust programming language among malware developers in campaigns like this.

Elastic Security Labs has identified a new information stealer called EDDIESTEALER, a Rust-based malware distributed through fake CAPTCHA campaigns. These campaigns trick users into executing malicious PowerShell scripts, which then deploy the infostealer onto their systems. EDDIESTEALER is hosted on multiple adversary-controlled web properties and employs the ClickFix social engineering tactic, luring unsuspecting individuals with the promise of CAPTCHA verification. The malware aims to harvest sensitive data, including credentials, browser information, and cryptocurrency wallet details.
This attack chain begins with threat actors compromising legitimate websites, injecting malicious JavaScript payloads that present bogus CAPTCHA check pages. Users are instructed to copy and paste a PowerShell command into their Windows terminal as verification, which retrieves and executes a JavaScript file called gverify.js. This script, in turn, fetches the EDDIESTEALER binary from a remote server, saving it in the downloads folder with a pseudorandom filename. The malware dynamically retrieves configuration data from a command-and-control server, allowing it to adapt its behavior and target specific programs. EDDIESTEALER is designed to gather system metadata and siphon data of interest from infected hosts, including cryptocurrency wallets, web browsers, password managers, FTP clients, and messaging apps like Telegram. The malware incorporates string encryption, a custom WinAPI lookup mechanism, and a mutex to prevent multiple instances from running. It also includes anti-sandbox checks and a self-deletion technique using NTFS Alternate Data Streams to evade detection. The dynamic C2 tasking gives attackers flexibility, highlighting the ongoing threat of ClickFix campaigns and the increasing use of Rust in malware development. Recommended read:

A Vietnam-based cybercriminal group, identified as UNC6032, is exploiting the public's fascination with AI to distribute malware. The group has been actively using malicious advertisements on platforms like Facebook and LinkedIn since mid-2024, luring users with promises of access to popular prompt-to-video AI generation tools such as Luma AI, Canva Dream Lab, and Kling AI. These ads direct victims to fake websites mimicking legitimate dashboards, where they are tricked into downloading ZIP files containing infostealers and backdoors.
The multi-stage attack involves sophisticated social engineering techniques. The initial ZIP file contains an executable disguised as a harmless video file using Braille characters to hide the ".exe" extension. Once executed, this binary, named STARKVEIL and written in Rust, unpacks legitimate binaries and malicious DLLs to the "C:\winsystem\" folder. It then prompts the user to re-launch the program after displaying a fake error message. On the second run, STARKVEIL deploys a Python loader called COILHATCH, which decrypts and side-loads further malicious payloads. This campaign has impacted a wide range of industries and geographic areas, with the United States being the most frequently targeted. The malware steals sensitive data, including login credentials, cookies, credit card information, and Facebook data, and establishes persistent access to compromised systems. UNC6032 constantly refreshes domains to evade detection, and while Meta has removed many of these malicious ads, users are urged to exercise caution and verify the legitimacy of AI tools before using them.

Cybercriminals are increasingly employing sophisticated social engineering techniques to distribute malware, with a recent surge in attacks leveraging fake CAPTCHA prompts and AI-generated TikTok videos. These campaigns, collectively known as "ClickFix," manipulate users into executing malicious PowerShell commands, leading to system compromise and the installation of information-stealing malware. A notable example involves a fake Google Meet page hosted on compromised WordPress sites, which tricks visitors into copying and pasting a specific PowerShell command under the guise of fixing a "Microphone Permission Denied" error. Once executed, the command downloads a remote access trojan (RAT), granting attackers full control over the victim's system.
The ClickFix technique is also being amplified through AI-generated TikTok videos that promise free access to premium software like Windows, Microsoft Office, Spotify, and CapCut. These videos instruct users to run PowerShell scripts, which instead install Vidar and StealC malware, capable of stealing login credentials, credit card data, and 2FA codes. Trend Micro researchers note that the use of AI allows for rapid production and tailoring of these videos to target different user segments. These tactics have proven highly effective, with one video promising to "boost your Spotify experience instantly" amassing nearly 500,000 views. Detecting and preventing ClickFix attacks requires a multi-faceted approach. Security experts recommend disabling the Windows Run program via Group Policy Objects (GPOs) or turning off the "Windows + R" hotkey. Additionally, users should exercise caution when encountering unsolicited technical instructions, verify the legitimacy of video sources, and avoid running PowerShell commands from untrusted sources. Monitoring for keywords like "not a robot," "captcha," "secure code," and "human" in process creation events can also help identify potential attacks. These measures, combined with public awareness, are crucial in mitigating the growing threat posed by ClickFix campaigns. Recommended read:

A concerning trend has emerged on TikTok where cybercriminals are exploiting the platform's widespread reach through AI-generated videos to distribute malware. These deceptive videos lure users into executing malicious PowerShell commands under the guise of providing instructions for software activation or unlocking premium features for applications like Windows, Microsoft Office, Spotify, and CapCut. Trend Micro researchers discovered that these videos, often featuring AI-generated voices and visuals, instruct viewers to run specific commands that ultimately download and install information-stealing malware such as Vidar and StealC.
One notable example highlighted by researchers involves a TikTok video claiming to offer instant Spotify enhancements, which amassed nearly half a million views along with a significant number of likes and comments. However, instead of delivering the promised benefits, the command provided in the video downloads a remote script that installs Vidar or StealC malware, executing it as a hidden process with elevated system privileges. These infostealers are designed to harvest sensitive information, including credentials, browser sessions, and cryptocurrency wallets, posing a substantial risk to unsuspecting users who fall victim to this social-engineering attack. Security experts warn that these attacks are leveraging the "ClickFix" technique and using AI to generate convincing "how-to" videos. By exploiting the trust users place in video tutorials and the desire for free software or features, cybercriminals are effectively tricking individuals into infecting their own systems. Once active, the malware connects to command-and-control (C&C) servers to exfiltrate stolen data. Vidar employs stealthy tactics, utilizing platforms like Steam and Telegram as Dead Drop Resolvers to hide C&C details, while StealC uses direct IP connections. Users are urged to exercise caution and verify the legitimacy of instructions before running any commands provided in online videos. Recommended read:

Cybercriminals are actively exploiting TikTok trends to spread malware using a deceptive tactic known as ClickFix. This technique involves tricking users into compromising their own systems with information-stealing malware such as Vidar, StealC, and the recently discovered Latrodectus. Attackers employ fake error messages or verification prompts, such as CAPTCHA screens, to manipulate users into running malicious scripts that install malware directly onto their devices. These commands are often disguised as instructions for activating programmes like Spotify Premium, Microsoft Office, CapCut, or Windows.
The spread of this threat has been amplified by TikTok's algorithm, as one such video received over 500,000 views, along with thousands of likes and comments, significantly increasing the risk of widespread infection. The videos guide users to run scripts, pretending they enable premium features. Once installed, malware such as StealC and Vidar can take screenshots, steal saved passwords and login details, collect credit card information, access cryptocurrency wallets, and steal text files and authentication data. The Latrodectus malware strain, which appears to have succeeded IcedID, is a downloader often used to install other malicious software, including ransomware. Cybersecurity researchers have also identified a sophisticated malware campaign utilizing ClickFix techniques to distribute EddieStealer, a Rust-based information stealer that targets sensitive data across multiple platforms. The EddieStealer campaign leverages a multi-stage attack methodology that begins with compromised websites displaying fraudulent CAPTCHA verification prompts. When victims encounter these fake authentication challenges, the malicious site automatically copies predetermined content to the user’s clipboard. The social engineering component encourages users to paste and execute the clipboard contents, believing they are completing a legitimate verification process. Recommended read:

iClicker, a widely-used student engagement platform, fell victim to a sophisticated ClickFix attack that compromised its website. The attack utilized a fake CAPTCHA prompt to deceive both students and instructors into unknowingly installing malware on their devices. This incident highlights the growing trend of cybercriminals exploiting user trust through social engineering tactics. iClicker, a subsidiary of Macmillan, serves approximately 5,000 instructors and 7 million students across numerous universities in the United States, making it a prime target for such malicious activities. The company has acknowledged the hijacking and issued a security bulletin advising affected users to take immediate action.
The ClickFix attack hinges on exploiting the familiarity users have with CAPTCHA verification processes. Instead of presenting a typical challenge to distinguish between humans and bots, the fake CAPTCHA prompts users to execute malicious scripts. This involves instructing users to open the Windows Run dialog, paste a provided script, and press Enter. Unbeknownst to the user, this action initiates a PowerShell script that retrieves and installs malware, granting attackers unauthorized access to their computer. The University of Michigan’s IT security team issued an early warning to students after discovering the malicious CAPTCHA. Sophos X-Ops revealed that the malware being installed through this method is the notorious Lumma Stealer. Lumma Stealer is a Malware-as-a-Service (MaaS) offering typically sold via Telegram channels, allowing cybercriminals to steal sensitive data, including browser passwords, cookies, cryptocurrency wallets, and session tokens. iClicker advised users who interacted with the false CAPTCHA between April 12-16 to run antivirus software and change their passwords immediately. The attack demonstrates the need for heightened cybersecurity awareness and vigilance when interacting with online prompts, even on trusted websites. Recommended read:

A new cyber espionage campaign dubbed "ClickFix" is actively targeting Linux systems, marking a concerning shift in focus for threat actors. This campaign, characterized by its precision and stealth, is not a generic, scattershot attack, but rather a calculated effort by groups like APT36, known for their cyberespionage capabilities. Attackers are exploiting vulnerabilities within Linux environments, highlighting the increasing sophistication and reliance on Linux by critical infrastructure and enterprises worldwide. The rise of ClickFix attacks serves as a wake-up call, demonstrating that attackers are now willing to go deeper and target smarter, making it harder for administrators who may have previously felt secure with standard hardening measures.
The core technique of ClickFix attacks involves social engineering to deceive users into executing malicious commands. Attackers have utilized websites that mimic legitimate entities, such as India’s Ministry of Defence, to lure victims. When users visit these sites, they are profiled based on their operating system and redirected to a tailored attack flow. On Linux, this often involves presenting a CAPTCHA page that, when interacted with, copies a shell command to the user’s clipboard. The user is then instructed to execute this command, which can lead to the installation of malware. The command used in these attacks drops a payload on the target system, which, in its current form, fetches a JPEG image from the attacker’s server. APT36 is reportedly linked to Pakistan and has been known to use sophisticated social engineering tactics to target Indian entities. Historically, APT36 primarily targeted Windows-based environments, but the ClickFix campaign signals a significant evolution in their strategy. This group focuses heavily on espionage, collecting information from government agencies, academic institutions, and defense sectors. What distinguishes APT36 from other advanced persistent threats is its knack for exploiting tools and techniques that leave systems vulnerable without raising immediate alarms. The cross-platform nature of ClickFix attacks, which now include Linux, highlights their versatility and the need for robust defensive measures. Recommended read:

State-sponsored hacking groups from North Korea, Iran, and Russia have been found leveraging the increasingly popular ClickFix social engineering tactic to deploy malware. This technique, which tricks users into clicking malicious links or executing malicious commands, has been adopted by advanced persistent threat (APT) groups, demonstrating the evolving nature of cyber threats and the increasing fluidity of tactics in the threat landscape. Researchers have observed these groups incorporating ClickFix into their espionage operations between late 2024 and early 2025.
Proofpoint researchers documented this shift, noting that the incorporation of ClickFix is replacing the installation and execution stages in existing infection chains. The technique involves using dialogue boxes with instructions to trick victims into copying, pasting, and running malicious commands on their machines. These commands, often disguised as solutions to fake error messages or security alerts, ultimately lead to the execution of harmful scripts. This dual-pronged approach makes ClickFix particularly insidious, as it leverages human interaction to bypass traditional security measures like antivirus software and firewalls. Specific examples of ClickFix campaigns include North Korea's TA427 targeting think tanks with spoofed emails and malicious PowerShell commands, and Iran's TA450 targeting organizations in the Middle East with fake Microsoft security updates. Russian-linked groups, such as UNK_RemoteRogue and TA422, have also experimented with ClickFix, distributing infected Word documents or using Google spreadsheet mimics to execute PowerShell commands. Experts warn that while some groups experimented with the technique in limited campaigns before returning to standard tactics, this attack method is expected to become more widely tested or adopted by threat actors.

The Interlock ransomware gang is actively employing ClickFix attacks to infiltrate corporate networks and deploy file-encrypting malware. This social engineering tactic tricks users into executing malicious PowerShell commands, often under the guise of fixing an error or verifying their identity. By impersonating legitimate IT tools, Interlock bypasses traditional security measures that rely on automated detection, as the malicious code is executed manually by the victim. This represents a significant shift in the cyber threat landscape, highlighting the importance of understanding and defending against these evolving tactics.
ClickFix attacks involve manipulating users through deceptive prompts, such as fake error messages, CAPTCHA verifications, or system update requests. Victims are tricked into copying and pasting harmful commands into their systems, leading to the silent installation of malware. Interlock has been observed using fake browser and VPN client updates to deliver malware, and even uses compromised websites to redirect users to fake popup windows. These windows ask the user to paste scripts into a PowerShell terminal, initiating the malware infection process. While the infrastructure supporting Interlock's ClickFix campaigns appears dormant since February 2025, the group's use of this technique signals ongoing innovation in their delivery mechanisms. This, combined with their consistent use of credential-stealing malware like LummaStealer and BerserkStealer, and a proprietary Remote Access Trojan (RAT), demonstrates Interlock's sophisticated approach to breaching networks. Organizations must enhance their security awareness training and implement measures to detect and prevent users from falling victim to ClickFix and other social engineering tactics. Recommended read:
