The short version

Russian hybrid attacks are hostile actions that can target a country without conventional warfare; the reports focus on cyber-assaults and possible disruption to essential services. ¹²
Lord Peter Ricketts says the UK should strengthen protection for energy, transport, air traffic control, defence sites, banking and water systems. ¹²
The reports warn about risks but do not identify a specific Russian attack on these UK services or establish that one is imminent. ¹²
Ricketts argues that ministers should explain the risk to the public and invest more in the ability of key systems to withstand disruption. ¹²

What are Russian hybrid attacks?

Hybrid attacks are hostile actions that use methods other than, or alongside, conventional military force. In these reports, the concern is that Russia could use cyber-assaults to interfere with systems people and businesses depend on, rather than launching a conventional military invasion. ¹²

The supplied reports do not provide a full definition or a complete list of possible methods. They concentrate on cyber threats and the potential for disruption to infrastructure and services. ¹²

Which UK services could be affected?

Ricketts identifies energy, transport, air traffic control and defence sites as areas where protection should be improved. The Guardian report also says he raised banking systems and water supplies as potential targets of cyber-assaults. ¹²

Resilience is the ability of a system to keep working during disruption or recover afterwards. The reports call for more investment in resilience, but do not explain which specific safeguards each sector should adopt. ¹²

How might an attack affect people?

A disruption to an important system could affect people through interruptions to services. Depending on what was targeted, the impact might involve energy, transport, air travel, banking or water. These are possible consequences discussed in the reports, not accounts of a confirmed incident. ¹²

Ricketts warned that such activity could eventually cause deaths. This is a warning about the seriousness of the risk; the reports do not say that a particular attack has caused deaths in the UK. ¹²

Why are officials raising the alarm now?

Ricketts says ministers should speak plainly to the public about possible threats and argues that the UK needs stronger protection for important systems. The reports also describe his comments in the context of warnings from the heads of MI5 and the British army. ¹²

The BBC reports that MI5 chief Sir Kevin McCallum said in an annual speech that threats from foreign states, including Russia and Iran, had quadrupled over the previous decade. That figure concerns foreign-state threats overall; it is not a count of Russian hybrid attacks alone. ¹

What is known, and what remains uncertain?

The reports outline concerns, sectors that could be targeted and calls for additional investment. They do not provide evidence of a specific planned operation, point to a particular vulnerability or say when an attack might occur. ¹²

They also do not describe the government’s complete response or provide a practical checklist for individuals. Their focus is on national protection and improving the ability of essential services to cope with disruption. ¹²

What we don't know yet

The reports do not identify a specific Russian operation against UK energy, transport, air traffic control, banking or water systems. ¹²
They do not say whether an attack is imminent, which systems might be targeted, or how extensive any disruption could be. ¹²
The reports do not specify what new protections the government will fund or when those measures might be introduced. ¹²
