Cybersecurity researchers have discovered a new malware campaign that leverages bogus Google Sites pages and HTML smuggling to distribute a commercial malware called AZORult in order to facilitate information theft.

"It uses an unorthodox HTML smuggling technique where the malicious payload is embedded in a separate JSON file hosted on an external website," Netskope Threat Labs researcher Jan Michael Alcantara said in a report published last week.

The phishing campaign has not been attributed to a specific threat actor or group. The cybersecurity company described it as widespread in nature, carried out with an intent to collect sensitive data for selling them in underground forums.

AZORult, also called PuffStealer and Ruzalto, is an information stealer first detected around 2016. It's typically distributed via phishing and malspam campaigns, trojanized installers for pirated software or media, and malvertising.

Once installed, it's capable of gathering credentials, cookies, and history from web browsers, screenshots, documents matching a list of specific extensions (.TXT, .DOC, .XLS, .DOCX, .XLSX, .AXX, and .KDBX), and data from 137 cryptocurrency wallets. AXX files are encrypted files created by AxCrypt, while KDBX refers to a password database created by the KeePass password manager.

The latest attack activity involves the threat actor creating counterfeit Google Docs pages on Google Sites that subsequently utilize HTML smuggling to deliver the payload.
