The US Federal Bureau of Investigations (FBI) reports that they are aware of a number of incidents in which the DoppelPaymer ransomware gang has begun to cold-calling victims who have not paid their ransoms, in order to intimidate them into paying the demands.
The FBI has said in a PIN (private industry notification) alert that these incidents have been taking place since February 2020. The alert notified the US private sector that this method of manipulation has been used by ransomware groups such as Conti, Ryuk, Sekhmet and Maze (the last two of which are now both defunct)
