FileFix Attack Using Steganography to Deploy StealC Infostealer

A new FileFix social engineering campaign impersonates Meta account suspension warnings to trick users into installing the StealC infostealer malware. The attack uses steganography to hide malicious scripts and executables within a JPG image. The campaign targets various credentials, cryptocurrency wallets, and cloud services. The FileFix technique abuses the File Explorer address bar to execute PowerShell commands, bypassing traditional detection methods. The attack was discovered by Acronis and observed over a two-week period, with multiple variants using different payloads and domains. The StealC malware aims to steal sensitive information from infected devices, including browser credentials, messaging app data, and cryptocurrency wallets. The FileFix technique was created by red team researcher mr.d0x and has been previously used by the Interlock ransomware gang. The attack uses a multilingual phishing site to trick users into copying and pasting a malicious command into the File Explorer address bar. The campaign abuses Bitbucket repositories to host malicious components, leveraging trust in the platform to bypass detection. The FileFix campaign is the most widespread, customized, and sophisticated to date, targeting users in over 16 countries. The phishing site has been translated into at least 16 different languages. The attack chain involves a phishing email impersonating Facebook security, warning users of account suspension. The attack uses AI-generated images in the steganography process. The FileFix technique is more elegant and less suspicious than ClickFix, using File Explorer instead of the Run dialog. The FileFix attack offers a broader range of high-value targets due to its use of File Explorer. Security researcher Eliad Kimhy predicts an increase in FileFix attacks in the near future. The FileFix attack involves a fake Cloudflare Turnstile verification page that redirects users to a Windows File Explorer search query. The attack uses a Windows shortcut LNK file disguised as a PDF to initiate the infection chain. The LNK file downloads a legitimate AnyDesk installer and a malicious MSI package that installs MetaStealer. The MSI package contains a DLL and a CAB archive with malicious files, including a MetaStealer dropper. The MetaStealer dropper is protected with Private EXE Protector and is designed to steal cryptocurrency wallets. The attack leverages the Windows search protocol to redirect users to an attacker-controlled SMB share. The FileFix attack has evolved to include a more sophisticated infection chain that bypasses traditional detection methods. The attack uses a multi-stage process involving Windows File Explorer, a fake PDF lure, and an MSI package to deploy MetaStealer. The FileFix attack has been observed to use a combination of social engineering and advanced technical techniques to evade detection.

UNC6040 and UNC6395 Target Salesforce Platforms in Data Theft Campaigns

The FBI has issued an alert about two cybercriminal groups, UNC6040 and UNC6395, targeting Salesforce platforms for data theft and extortion. UNC6395 exploited compromised OAuth tokens for the Salesloft Drift application, while UNC6040 used vishing campaigns and modified Salesforce tools to breach Salesforce instances. Both groups have been active since at least October 2024, impacting multiple organizations. UNC6040 has been linked to extortion activities, with Google attributing these to a separate cluster, UNC6240, which has claimed to be the ShinyHunters group. The ShinyHunters group, along with Scattered Spider and LAPSUS$, recently announced they are going dark, but experts warn that the threat persists. UNC6040 impersonated corporate IT support personnel to gain access to Salesforce environments and used modified versions of Salesforce's Data Loader to exfiltrate data. Salesforce re-enabled integrations with Salesloft technologies, except for the Drift app, which remains disabled.

CISA Defunding and Dismantling Affects Cybersecurity Response

The Cybersecurity and Infrastructure Security Agency (CISA) is being defunded and dismantled, jeopardizing the timely identification and mitigation of cyber vulnerabilities. This development leaves organizations more vulnerable to zero-day exploits and delays in response times. CISA's role in coordinating vulnerability information and providing detailed advisories is crucial for accelerating the discovery and resolution of security issues. CISA's partnership with the Center for Internet Security has ended, and over a hundred employees have been laid off. The Common Vulnerabilities and Exposures (CVE) program, funded through CISA, was extended but faces an uncertain future. The Cybersecurity Information Sharing Act of 2015 is up for renewal, with no clear indication of its future. The defunding and dismantling of CISA will increase the risk of exploitation for businesses and their customers, as organizations will have to rely on their own resources or public disclosures to identify vulnerabilities. This delay can leave systems exposed to attacks for longer periods.

New HybridPetya Ransomware Exploits UEFI Secure Boot Bypass Vulnerability

A new ransomware variant, HybridPetya, has been discovered. It resembles the Petya/NotPetya malware but includes the ability to bypass UEFI Secure Boot using the CVE-2024-7344 vulnerability. HybridPetya encrypts the Master File Table (MFT) on NTFS-formatted partitions and can compromise modern UEFI-based systems. The ransomware operates through a bootkit and an installer, with the bootkit managing encryption and decryption processes. The ransomware has been observed in samples uploaded to VirusTotal in February 2025, with no evidence of active use in the wild. The vulnerability exploited by HybridPetya was patched in January 2025. The ransomware encrypts the MFT and displays a fake CHKDSK message to deceive victims. It demands a $1,000 ransom in Bitcoin, with a total of $183.32 received between February and May 2025. The ransom note provides an option for victims to enter a decryption key after payment, which triggers the decryption process. The bootkit also recovers legitimate bootloaders from backups created during installation. The ransomware triggers a system crash during bootloader changes, ensuring the bootkit binary is executed upon reboot. HybridPetya may be a research project, proof-of-concept, or early version of a cybercrime tool under limited testing. HybridPetya combines the destructive capabilities of NotPetya, the recoverable encryption functionality of Petya ransomware, and the ability to bypass Secure Boot protections. It can deploy malicious UEFI payloads directly to the EFI System Partition and encrypt the Master File Table (MFT). HybridPetya's ability to install harmful code directly into a computer's UEFI firmware makes it hard for security teams to detect. The emergence of HybridPetya highlights the growing threat from UEFI bootkits that reside at a computer's startup sequence level.
