Russian intelligence has been accused by the US and UK of carrying out cyberattacks using new techniques after it was exposed that its hackers continue to target governments, organisations and energy providers around the world.

A joint advisory by the US Department for Homeland Security's Cybersecurity Infrastructure Security Agency (CISA), FBI and the National Security Agency (NSA), as well as the UK National Cyber Security Centre warned organisations about updated Tactics, Techniques and Procedures (TTPs) used by Russia's foreign intelligence service, the SVR -- a group also known by cybersecurity researchers as APT29, Cozy Bear and The Dukes.
