This threat involves a fraudulent CCleaner installer distributed through a convincing imitation website. Upon installation, it launches a multi-stage infection chain using CScript to modify Chrome's Security Extension and install GhostDesk, a malicious Chrome extension functioning as spyware. GhostDesk performs extensive surveillance activities including credential theft, keylogging, screenshot capture, cookie harvesting, and cryptojacking. It establishes command-and-control communication via WebSocket connections and has the capability to execute arbitrary code within browser tabs. The infection technique is also observed in fake versions of other popular software such as 7-Zip and Adobe Acrobat.

The GhostDesk spyware compromises user privacy and security by stealing credentials, logging keystrokes, capturing screenshots, harvesting cookies, and performing cryptojacking. The ability to execute arbitrary code within browser tabs and maintain persistent command-and-control communications increases the risk of further compromise and data exfiltration. This can lead to unauthorized access to sensitive information and system resources.

No official patch or fix is available as this is a malware campaign involving fake software distribution. Mitigation involves user education to avoid downloading software from unverified or imitation websites. Security teams should block known malicious domains and IPs associated with this threat, such as 'ccleanerwind.top' and 'liderongrade.duckdns.org', and monitor for indicators of compromise including the listed hashes. Removing the malicious Chrome extension and scanning infected systems with updated anti-malware tools is recommended.
