US cyber-attack: Hack of government agencies and companies poses 'grave risk'

Reuters

US officials have warned that a major hacking campaign uncovered this week poses a "grave risk" to the government, critical infrastructure and the private sector.

The US Treasury and commerce departments were among those attacked.

The US Cybersecurity and Infrastructure Security Agency (Cisa) said thwarting the attack would be "highly complex".

Many suspect the Russian government is responsible. It has denied the claims as "baseless".

In a statement on Thursday, Cisa said government agencies, critical infrastructure entities and private sector organisations had been targeted by what it called an "advanced persistent threat actor", beginning in at least March 2020.

The actor behind the hacks "demonstrated patience, operational security, and complex tradecraft in these intrusions", it said.

Cisa did not identify who was behind the attack, which agencies and organisations had been breached, or what information had been stolen or exposed.

Meanwhile, US President-elect Joe Biden said he would make cyber-security a "top priority" of his administration.

"We need to disrupt and deter our adversaries from undertaking significant cyber-attacks in the first place," he said. "We will do that by, among other things, imposing substantial costs on those responsible for such malicious attacks, including in coordination with our allies and partners."

What's the background?

Several US government agencies are reported to have been attacked in the hacking campaign, which has been described as "significant and ongoing."

Hackers are known to have at least monitored data within US departments including state, defence, homeland security, treasury and commerce, Reuters news agency reports.

The Energy Department and National Nuclear Security Administration also have evidence that hackers accessed their networks, Politico magazine reported, citing officials familiar with the matter.

Cisa said the perpetrators managed to breach computer networks using network management software made by the Texas-based IT company SolarWinds.

Up to 18,000 SolarWinds Orion customers downloaded updates containing a back door that let hackers in.

All US federal civilian agencies were told to remove SolarWinds from their servers earlier this week as a result of the hack.

In its statement on Thursday, Cisa said it was investigating "evidence of additional access vectors, other than the SolarWinds Orion platform".

Neither Cisa nor the FBI has publicly said who is believed be responsible for the attacks, but private security companies and officials quoted in US media have pointed the finger at Russia.

In a statement shared on social media on Monday, the Russian embassy in the US said it "does not conduct offensive operations in the cyber domain".
