Ransomware Operators' New Tactic

Ransomware operators, claiming to be from the BianLian group, have been sending extortion letters via snail mail to executives, demanding $250,000 to $350,000 in Bitcoin. The letters claim that the operators have gained access to the company's systems and have exported sensitive data, including customer information, employee data, and financial documents.

However, researchers believe that the attacks are fake and there is no evidence of any actual compromise. The wording of the message is also inconsistent with previous ransom notes sent by the BianLian group. The return address on the letters points to a real office building in Boston, USA.

The use of snail mail to send extortion demands is a new tactic for ransomware operators, who typically rely on email or other digital means to communicate with their victims. It is unclear why the operators have chosen to use this method, but it may be an attempt to add a sense of legitimacy or urgency to their demands.

Companies that receive such letters should be cautious and not pay the demanded ransom. Instead, they should report the incident to the authorities and conduct a thorough investigation to determine if there has been any actual compromise.
