US, UK and Australia sanction Russian cyber firms over ransomware links

LONDON (Reuters) -The United States, Australia and Britain announced coordinated sanctions on Wednesday against Russia-based web company Media Land, accusing it of supporting ransomware operations.

U.S. Treasury's Office of Foreign Assets Control also designated three members of the Russian company's leadership and three of its sister companies, the Department of Treasury said in a statement.

"These so-called bulletproof hosting service providers like Media Land provide cybercriminals essential services to aid them in attacking businesses in the United States and in allied countries," said John Hurley, under secretary of the treasury for terrorism and financial intelligence.

Britain announced parallel measures, adding Aeza Group LLC to its Russia sanctions regime and six designations under its cyber regime.

Those include Media Land and another hosting provider, ML.Cloud LLC, along with four individuals accused of involvement in malicious cyber activity.

UK sanctions include asset freezes and director disqualification orders for all targets, with travel bans applied to the four individuals.

Aeza Group also faces restrictions on internet and trust services, which prohibit British businesses from providing technical support or hosting services.

ML.Cloud is a Media Land sister company whose technical infrastructure is often used in conjunction with Media Land, including in ransomware and DDOS attacks, the U.S. statement said.

The Russian embassy in London did not immediately respond to a request for comment. Neither Aeza Group nor ML.Cloud immediately responded to a request for comment. It was not immediately possible to reach Media Land.

Australia said it was imposing similar measures to align with its partners, citing the need to disrupt ransomware networks that have hit hospitals, schools and businesses.
