And the hackers already appear to be leveraging their new tool to plot their next attack, says Bogdan Botezatu, Bitdefender’s director of threat research and reporting.

The hackers also appear to be working on infrastructure that could allow them to sell access to other attackers, according to Vikram Thakur, a technical director at the security firm Symantec, which has previously run efforts to disrupt…
