Attackers are distributing a fake CCleaner installer from a convincing lookalike website to trick Windows users into installing spyware. The malware modifies Google Chrome and installs a malicious extension (“GhostDesk”) that can steal credentials, capture screenshots, and log keystrokes.
Key findings
- A lookalike CCleaner download site delivers a malicious “CCleaner.exe” instead of the real installer.
- The fake installer patches Chrome’s Security Extension and drops JavaScript files that act as a malicious extension labeled “GhostDesk.”
- The GhostDesk extension supports keylogging, form-data theft, cookie theft, tab screenshots, and remote script execution in the browser.
- Multiple other fake installers (e.g., 7-Zip and Adobe Acrobat) were found using the same infection chain and C2 domain.
Who’s being targeted
- Commonly targeted roles: All employees, IT support / helpdesk, Desktop engineering / endpoint teams, Security awareness program participants.
- Affected industries: Any organization where employees download software to Windows endpoints, General consumer and enterprise Windows environments.
- Attack channels: website.
- Impersonated: CCleaner (official download page).
Awareness takeaways
- Train users to verify the exact website address before downloading software (lookalike domains are a common trap).
- Warn employees that a professional-looking download page (or a “Pro” button) is not proof the site is legitimate.
- Treat software-download links from ads and shared links (social media, SMS, email) as high risk; prefer trusted stores or the known official site.
- Explain that ‘utility installers’ can hide spyware behavior; users should avoid downloading tools outside approved channels.
Red flags to watch for
- Lookalike domain (not the real vendor site): ccleanerwind[.]top
- Both the “Pro” and normal download buttons deliver the same executable
- Installer filename/icon match the real app, but internal details don’t match a real release

You google CCleaner, click a download, and boom, your Chrome quietly turns into a keylogger. This fake site at ccleanerwind.top gives you a bogus 'CCleaner.exe' that patches Chrome and sneaks in a GhostDesk extension to log keys, steal forms and cookies, and screenshot your tabs. The trap: the page looks polished, even has a shiny Pro button, but both buttons drop the same spyware installer, and once it’s in, GhostDesk can see what you type into work apps and websites. Here’s the move: when you need CCleaner, 7-Zip, or Acrobat, don’t trust search ads or random links, type the official site yourself or use our approved software portal.
