FileFix Attack Uses Fake Meta Suspensions to Spread StealC Malware

 

A new cyber threat known as the FileFix attack is gaining traction, using deceptive tactics to trick users into downloading malware. According to Acronis, which first identified the campaign, hackers are sending fake Meta account suspension notices to lure victims into installing the StealC infostealer. Reported by Bleeping Computer, the attack relies on social engineering techniques that exploit urgency and fear to convince targets to act quickly without suspicion. 

The StealC malware is designed to extract sensitive information from multiple sources, including cloud-stored credentials, browser cookies, authentication tokens, messaging platforms, cryptocurrency wallets, VPNs, and gaming accounts. It can also capture desktop screenshots. Victims are directed to a fake Meta support webpage available in multiple languages, warning them of imminent account suspension. The page urges users to review an “incident report,” which is disguised as a PowerShell command. Once executed, the command installs StealC on the victim’s device. 

To execute the attack, users are instructed to copy a path that appears legitimate but contains hidden malicious code and subtle formatting tricks, such as extra spaces, making it harder to detect. Unlike traditional ClickFix attacks, which use the Windows Run dialog box, FileFix leverages the Windows File Explorer address bar to execute malicious commands. This method, attributed to a researcher known as mr.fox, makes the attack harder for casual users to recognize. 

Acronis has emphasized the importance of user awareness and training, particularly educating people on the risks of copying commands or paths from suspicious websites into system interfaces. Recognizing common phishing red flags—such as urgent language, unexpected warnings, and suspicious links—remains critical. Security experts recommend that users verify account issues by directly visiting official websites rather than following embedded links in unsolicited emails. 

Additional protective measures include enabling two-factor authentication (2FA), which provides an extra security layer even if login credentials are stolen, and ensuring that devices are protected with up-to-date antivirus solutions. Advanced features such as VPNs and hardened browsers can also reduce exposure to such threats. 

Cybersecurity researchers warn that both FileFix and its predecessor ClickFix are likely to remain popular among attackers until awareness becomes widespread. As these techniques evolve, sharing knowledge within organizations and communities is seen as a key defense. At the same time, maintaining strong cyber hygiene and securing personal devices are essential to reduce the risk of falling victim to these increasingly sophisticated phishing campaigns.

‘FileFix’ Malware Trick Amplifies Interlock Ransomware Threat With Evolved Attack Tactic

 

Cybersecurity researchers have identified a dangerous new twist to the notorious ClickFix malware tactic. The evolved variant—called FileFix—is now being weaponized in active ransomware campaigns, further advancing the threat landscape.

ClickFix typically lures users by showing them a bogus issue—like a fake CAPTCHA or a misleading virus alert—and then offers a “solution” that involves copying and pasting a command from a compromised website into the Windows Run dialog. This command often triggers the download and execution of malicious software.

However, the new FileFix technique modifies that approach. Instead of using the Run command, it instructs users to paste a string into the File Explorer address bar. Though it appears as a legitimate file path, the string is actually a disguised PowerShell command, cleverly masked using comment syntax.

In recent attacks observed in the wild, executing this PowerShell string installs a PHP-based version of the Interlock Remote Access Trojan (RAT). Once active, the RAT performs a range of actions—scanning system and network configurations, identifying backup systems, navigating through local file directories, probing Active Directory environments, and even inspecting domain controllers.

Eventually, the RAT leads to the deployment of the Interlock ransomware encryptor.

Interlock first appeared in September 2024 and was publicly detected by November the same year. It stood out by targeting both Windows and FreeBSD systems. Some high-profile victims include Wayne County (Michigan), Texas Tech University Health Sciences Center, Heritage Bank & McCormick–Priore, and Kettering Health.

The ransomware employs the typical double extortion approach—stealing sensitive data before locking systems with encryption to demand ransom.

As of mid-2025, Interlock has been linked to at least 14 confirmed incidents, with healthcare entities making up about one-third of the total. This shift in delivery method suggests active development of the malware and underscores its ongoing threat to global organizations.
