Russian cyber attacks are being deployed with new techniques – including exploiting vulnerabilities like the recent Microsoft Exchange zero-days – as its hackers continue to target governments, organisations and energy providers around the world.<\/p>\n

A joint advisory<\/a> 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 looks to warn 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<\/a>. <\/p>\n

It comes after cybersecurity agencies in the US and the UK attributed the SolarWinds attack to Russia’s civilian foreign intelligence service<\/a>, as well as several campaigns targeting Covid-19 vaccine developers<\/a>. <\/p>\n

“The SVR is a technologically sophisticated and highly capable cyber actor. It has developed capabilities to target organisations globally, including in the UK, US, Europe, NATO member states and Russia’s neighbours,” said the alert.<\/p>\n

The advisory warns that Russian cyber attackers have updated their techniques and procedures in an effort to infiltrate networks and avoid detection, especially when some organisations have attempted to adjust their defences after previous alerts about cyber threats.<\/p>\n

This includes the attackers using open source tool Sliver as a means of maintaining access to compromised networks and making use of numerous vulnerabilities, including vulnerabilities in Microsoft Exchange<\/a>.<\/p>\n

Sliver is an open source red team tool, a tool used by penetration testers when legally and legitimately testing network security, but in this case is being abused to consolidate access to networks compromised with WellMess and WellMail, custom malware associated with SVR attacks.<\/p>\n
