LAPSUS$ recruiting insiders through Telegram (source).

We suggest dealing with LAPSUS$-design assaults like you would deal with an expert danger. Presume violation of the boundary, limitation gain access to, and look for abnormal inconsistencies from standard habits.
Right-size access as well as reduce exposure
