Hackers' broad attack sets cyber experts worldwide scrambling to defend networks
Suspected Russian hackers who broke into US government agencies also spied on less high-profile organisations, including groups in Britain, a US internet provider and a county government in Arizona, according to web records and a security source.
More details were revealed on Friday of the cyber espionage campaign that has computer network security teams worldwide scrambling to limit the damage as the outgoing administration of US President Donald Trump offered little information.
Networking gear maker Cisco Systems Inc said a limited number of machines in some of its labs had been found with malicious software on them, without saying if anything had been taken. A person familiar with the company's ongoing probe said fewer than 50 were compromised.

In Britain, a small number of organisations were compromised and not in the public sector, a security source said.
Shares in cyber security companies FireEye Inc, Palo Alto Networks and Crowdstrike Holdings rose on Friday as investors bet that the spate of disclosures from Microsoft Corp and others would boost demand for security technology.
Reuters identified Cox Communications Inc and Pima County, Arizona government as victims of the intrusion by running a publicly available coding script here from researchers at Moscow-based private cybersecurity firm Kaspersky. The hack hijacked ubiquitous network management software made by SolarWinds Corp. Kaspersky decrypted online web records left behind by the attackers.
The breaches of US government agencies, first revealed by Reuters on Sunday, hit the Department of Homeland Security, the Treasury Department, State Department and Department of Energy. In some cases the breaches involved monitoring emails but it was unclear what hackers did while infiltrating networks, cybersecurity experts said.
Trump has not said anything publicly about the intrusion. He was being briefed "as needed," White House spokesman Brian Morgenstern told reporters. National security adviser Robert O'Brien was leading interagency meetings daily, if not more often, he said.
"They're working very hard on mitigation and making sure that our country is secure. We will not get into too many details because we're just not going to tell our adversaries what we do to combat these things," Morgenstern said.
No determinations have been made on how to respond or who was responsible, a senior US official said.
SolarWinds, which disclosed its unwitting role at the center of the global hack on Monday, has said that up to 18,000 users of its Orion software downloaded a compromised update containing malicious code planted by the attackers. The attack was believed to be the work of an "outside nation state," SolarWinds said in a regulatory disclosure.
People familiar with the matter have said the hackers were believed to be working for the Russian government. Kremlin spokesman Dmitry Peskov dismissed the allegations.
On Friday, US Representative Stephen Lynch, head of the House of Representatives Committee on Oversight and Reform panel's national security subcommittee, said the information provided by the Trump administration was "very disappointing."
"This hack was so big in scope that even our cybersecurity experts don't have a real sense yet in terms of the breadth of the intrusion itself," adding that it would take some time to fully vet all the agencies and targets.
The breach appeared to provide President-elect Joe Biden with an immediate headache when he takes office on Jan. 20. His transition team's executive director Yohannes Abraham told reporters on Friday there would be "substantial costs" and the incoming administration "will reserve the right to respond at a time and in a manner of our choosing, often in close coordination with our allies and partners."
Microsoft, one of the thousands of companies to receive the malicious update, said it had notified more than 40 customers whose networks were further infiltrated by the hackers.
Around 30 of those customers were in the United States, Microsoft said, with the remaining victims found in Canada, Mexico, Belgium, Spain, Britain, Israel and the United Arab Emirates. Most worked with information technology companies, some think tanks and government organisations.
