impersonation

Recent investigations from Palo Alto have revealed the use of "click fix" campaigns for distributing Lumma Stealer malware, which exploit user interaction by embedding malicious scripts into the copy-paste buffer. Victims are tricked into executing harmful commands through seemingly benign instructions on malicious web pages. Key tactics include: - Domain Impersonation: Registering domains that resemble legitimate services (e.g., windows-update[.]site). - Abuse of Trusted Platforms: Hosting malicious pages on reputable platforms like Google Sites. - PowerShell Script Delivery: Using data binaries that execute as PowerShell scripts. - DLL Side-Loading: Distributing zip archives with decoy files alongside legitimate executables for side-loading Lumma Stealer DLLs. Examples of malicious activity include: 1. Fake Google Meet Page: A fraudulent page instructs users to execute a PowerShell command that downloads a script from tlgrm-redirect[.]icu, leading to the download of Lumma Stealer files from plsverif[.]cfd/1.zip and executing a DLL file (DuiLib_u.dll) through side-loading. 2. Fake Windows Update Site: The site windows-update[.]site prompts users to run a PowerShell command that downloads a file from overcoatpassably[.]shop/Z8UZbPyVpGfdRS/maloy[.]mp4, which functions as a PowerShell script. Malicious traffic patterns include HTTP POST requests to tlgrmverif[.]cyou/log.php and downloads from plsverif[.]cfd and overcoatpassably[.]shop. Active command-and-control (C2) domains for Lumma Stealer are: - web-security3[.]com - techspherxe[.]top Inactive C2 domains include: - hardswarehub[.]today - earthsymphzony[.]today Key files associated with these campaigns are: - A PowerShell script from tlgrm-redirect[.]icu/1.txt (SHA256: 909ed8a135…). - A zip archive from plsverif[.]cfd/1.zip (SHA256: 0608775a345…). - A side-loaded DLL (DuiLib_u.dll, SHA256: b3e8b610ef…). Indicators of compromise include active domains like windows-update[.]site and sites[.]google[.]com/view/get-access-now-test/verify-your-account, and associated domains such as authentication-safeguard[.]com, plsverif[.]cfd, and tlgrmverif[.]cyou.
