1 distinct threat actor attributed by public researchers. Open in Mallory to see the full evidence chain and overlapping campaigns.
Apart from Antino, the threat actor also uses the XG-Web remote-access and data-theft framework for managing campaigns and victim information.
17 distinct techniques documented for this family, organized by ATT&CK tactic.
In its largest operation, a single planted script placed a watering-hole on more than 15 government webmail tenants in a Middle Eastern country at once.
The researchers explained that the threat actor obtained write access to the webmail installation used by multiple government ministries and agencies after compromising a shared web-hosting platform operated by the state telecommunications provider and national services agency.
Once installed, the extension could read cookies, watch for new session tokens, inspect browsing history and bookmarks, take screenshots, and capture clipboard contents.
Stolen cookies can let criminals reuse a logged-in session, which is why browser cookie theft risks remain serious even where an account uses multi-factor authentication. | The China-based group compromised government webmail systems, stole browser cookies, and used that access to watch activity inside affected networks.
Once installed, the extension could read cookies, watch for new session tokens, inspect browsing history and bookmarks, take screenshots, and capture clipboard contents.

After execution, the script established a WebSocket connection to the attacker's command-and-control (C2) server
When a ministry staff member logged in, the script opened a WebSocket to the C&C, completed the cryptographic handshake and reported in.
Once running, Antino uses the Microsoft Graph API as its C&C channel, hiding its traffic inside legitimate Microsoft cloud services... the backend created a public Google Document, wrote an obfuscated payload into the body, and had implants fetch the documents and execute the payloads.
