Researchers identified an exposed server at 94[.]103[.]1[.]175:16482 hosting counterfeit Cloudflare verification pages that use a ClickFix-style CAPTCHA lure. The pages attempt to copy an obfuscated PowerShell command to a visitor’s clipboard and persuade them to run it, leading to a protected executable hosted on the same infrastructure. Two Rust droppers unpacked near-identical WallStealer payloads designed to collect browser credentials, cookies, payment information, screenshots, system details, and data from messaging, gaming, FTP, and cryptocurrency-wallet applications.
WallStealer uses Steam profile persona names as dead-drop resolvers to obtain command-and-control destinations, complicating infrastructure tracking. Investigators also found stube.exe, a loader containing an XMRig 6.25.0-derived mining DLL configured to connect to 94[.]103[.]1[.]175:3333, tying cryptomining capability to the same delivery environment. The samples were analyzed statically without execution or infrastructure interaction, and defects in purported delivery scripts prevented confirmation that the campaign successfully infected victims.

The stube.exe loader was found to decrypt a separate mining loader containing an XMRig 6.25.0-derived DLL configured to use 94[.]103[.]1[.]175:3333. This shared IP linked the payload-delivery service on port 16482 with cryptomining infrastructure on port 3333.
Researchers decrypted two near-identical WallStealer payloads from Rust droppers, finding capabilities to steal browser, payment, host, messaging, gaming, FTP, and cryptocurrency-wallet data. The payloads retrieved Steam profile persona names as dead-drop resolvers for subsequent command-and-control destinations.
A July 2026 investigation found an open directory at 94[.]103[.]1[.]175:16482 hosting fake Cloudflare verification content and protected executables. The CAPTCHA lure attempted to copy an obfuscated PowerShell command that would download and run a file from the same server.

A wave of **social-engineering-driven malware delivery** is abusing “verification” and “fix” workflows to trick users into running attacker-supplied commands that install information stealers. LevelBlue reported a campaign using **fake Cloudflare-style CAPTCHA pages** on compromised websites to convince Windows users to manually execute malicious **PowerShell** commands, resulting in **StealC** deployment; StealC is described as exfiltrating browser credentials, crypto wallet data, Steam and Outlook credentials, system information, and screenshots over **RC4-encrypted HTTP** to a C2 server. Intego also identified an evolved **ClickFix** technique on macOS (“**Matryoshka**”) that leverages **typosquatting** to redirect users to pages instructing them to paste “fix” commands into Terminal; the loader then retrieves an AppleScript payload to steal browser credentials and target wallet apps (e.g., *Trezor Suite*, *Ledger Live*), including repeated fake password prompts as a fallback. Separately, other credential-theft campaigns are also leaning heavily on lures that exploit user trust and routine workflows. Morphisec described **Noodlophile** evolving from fake AI video platform ads to **fake job postings** and phishing “assessments,” delivering multi-stage stealers/RATs via techniques including **DLL sideloading**, while continuing to use **Telegram bots** for exfiltration/C2 and adding file-bloating content intended to disrupt automated analysis. These developments reinforce that user-in-the-loop execution (copy/paste commands, “verification” steps, and recruitment-themed forms) remains a high-yield initial access vector for stealers across both Windows and macOS environments.

A **ClickFix**-style malware campaign has been observed using **fake CAPTCHA** pages on compromised websites to trick users into **manually executing** malicious commands, enabling initial access while evading controls that focus on downloaded files. In the reported activity, victims are prompted to copy a **PowerShell** command and run it themselves; the script then downloads additional stages from attacker infrastructure (including `91.92.240.219`), verifies user interaction by checking clipboard activity, and proceeds through a multi-stage infection chain. The payload is an **information stealer** targeting data from **25+ web browsers**, cryptocurrency wallets (e.g., *MetaMask*), and enterprise VPN configurations, with checks for virtualized environments and security tooling prior to exfiltration. Separately reported threat activity in the same time window includes **UnsolicitedBooker** targeting Central Asian telecoms with phishing-delivered backdoors (**LuciDoor** and **MarsSnake**) and **APT28** running *Operation MacroMaze*, which uses weaponized Office documents and `INCLUDEPICTURE` fields pointing to `webhook[.]site` URLs as a tracking mechanism and to support follow-on macro-based payload delivery. A video-style weekly briefing also mentions an evolution of ClickFix where an initial command uses `nslookup` and parses the response for execution, but it is a multi-topic roundup rather than a primary source on the fake-CAPTCHA infostealer campaign; a malware newsletter roundup is likewise a link collection and does not add specific, corroborating details about the ClickFix CAPTCHA infostealer operation.

Security agencies and researchers warned that **ClickFix** social-engineering attacks are spreading through fake verification and brand-impersonation pages that mimic services such as **Google reCAPTCHA** and **Cloudflare**, then trick users into opening `Win+R` or Terminal and pasting clipboard-loaded commands. Recent campaigns have used poisoned websites, fake search results, and spoofed update pages to push victims into launching malicious PowerShell, `mshta`, WebDAV, or shell-based payloads, turning trusted brands and verification flows into an initial access vector without directly compromising the impersonated organizations. The activity has delivered a wide range of malware, including **ACR Stealer**, **HijackLoader**, **StealC**, **Remus**, **Amatera Stealer**, **CastleLoader**, **NetSupport**, Rust-based stealers, and a DPRK-linked macOS backdoor tied to **Contagious Interview**. Microsoft said ACR Stealer campaigns targeting enterprise users stole browser credentials, cookies, tokens, and business files, used scheduled tasks and process injection for persistence and evasion, and in some cases relied on **EtherHiding** to resolve command-and-control infrastructure from Ethereum smart contracts; the macOS campaign similarly used clipboard-driven execution, LaunchAgent persistence, and follow-on payloads that targeted browser data, developer and cloud keys, and cryptocurrency wallets. Defenders were urged to block command execution from untrusted prompts, hunt for published indicators of compromise, and educate users that legitimate verification pages do **not** require running commands locally.
