Symantec researchers report details about the activities of a cybercrime group they track as Bluebottle, revealing significant similarities to the TTP gang OPERA1ER.
As the researchers found out, Bluebottle hackers used a signed Windows driver to attack banks in French-speaking countries. At the same time, the actions and goals correspond to the OPERA1ER profile, which were attributed to at least 35 successful attacks in the period from 2018 to 2020.
