Threat details

At the time of publication, it is unclear how Banjori is initially delivered, although there are unconfirmed reports indicating it may distributed in spam email campaigns.

Once installed, Banjori will inject hooks into all browser-related processes. It will then monitor these to determine if a user visits a banking site, at which point it will attempt to phish or otherwise obtain their data. A secondary module will check the system language and search for sensitive files in the Users folder. Any extracted information is then sent back to a command and control server.
