The operator of a major US fuel pipeline hit by a cyberattack says it hopes to have services mostly restored by the end of the week as the FBI and administration officials identified the culprits as a gang of criminal hackers.
Colonial Pipeline, which delivers about 45 per cent of the fuel used on the US East Coast, halted operations last week after revealing a ransomware attack that it said had affected some of its systems.
On Monday, US officials sought to soothe concerns about price spikes or damage to the economy by stressing that the fuel supply had so far not been disrupted, and the company said it was working towards "substantially restoring operational service" by the weekend.
But the attack underscored the vulnerabilities of the nation's energy sector and other critical industries whose infrastructure is largely privately owned. Ransomware attacks are typically carried out by criminal hackers who scramble data, paralysing victim networks, and demand large payments to decrypt it.
The Colonial attack was a reminder of the real-world implications of the burgeoning threat. Even as the Biden administration works to confront organised hacking campaigns sponsored by foreign governments, it must contend with difficult-to-prevent attacks from cybercriminals.
"We need to invest to safeguard our critical infrastructure," President Joe Biden said on Monday.
The attack came as the administration, still grappling with its response to massive breaches by Russia of federal agencies and private corporations, works on an executive order aimed at bolstering cybersecurity defences.
The Justice Department has formed a ransomware task force designed for situations like Colonial Pipeline, and the Energy Department on April 20 announced a 100-day initiative focused on protecting energy infrastructure from cyber threats.
Despite that, the challenge facing the government and the private sector remains immense.
In this case, the FBI moved with unusual speed to pinpoint blame, saying the criminal syndicate whose ransomware was used in the attack is named DarkSide.
The group's members are Russian speakers, and the syndicate's malware is coded not to attack networks using Russian-language keyboards.
Anne Neuberger, the White House deputy national security adviser for cyber and emerging technology, said at a briefing that the group emerged a few months ago. She said the group's business model is to demand ransom payments from victims and then split the proceeds, relying on what she said was a "new and very troubling variant".
She declined to say if Colonial had paid any ransom, and the company has not given any indication of that.
Though the FBI has historically discouraged victims from making payments for fear of promoting additional attacks, she acknowledged "the very difficult" situation victims faced and said the administration needed to look "thoughtfully at this area".
The US sanctioned the Kremlin last month for a hack of federal government agencies that officials have linked to a military intelligence unit and described as an intelligence-gathering operation. In this case, though, the hackers are not known to be working at the behest of any foreign government.
The group posted a statement on its dark web site describing itself as apolitical. "Our goal is to make money, and not creating problems for society," DarkSide said.
Asked on Monday whether Russia was involved, Biden said: "I'm going to be meeting with President (Vladimir) Putin, and so far there is no evidence based on, from our intelligence people, that Russia is involved, although there is evidence that the actors, ransomware, is in Russia.
"They have some responsibility to deal with this."
