A phishing campaign is using a fake Google Account security page to deliver a web-based app capable of stealing one-time passcodes, harvesting cryptocurrency wallet addresses, and proxying attacker traffic through victims’ browsers.

The attack leverages Progressive Web App (PWA) features and social engineering to deceive users into believing they are interacting with a legitimate Google Security web page and inadvertently installing the malware.

PWAs run in the browser and can be installed from a website, just like a standalone regular application, which is displayed in its own window without any visible browser controls.

A new GlassWorm malware attack through compromised OpenVSX extensions focuses on stealing passwords, crypto-wallet data, and developer credentials and configurations from macOS systems.

The threat actor gained access to the account of a legitimate developer (oorzc) and pushed malicious updates with the GlassWorm payload to four extensions that had been downloaded 22,000 times.

GlassWorm attacks first appeared in late October, hiding the malicious code using “invisible” Unicode characters to steal cryptocurrency wallet and developer account details. The malware also supports VNC-based remote access and SOCKS proxying.
