Microsoft should soon have some idea which and how many SolarWinds customers were affected, as it recently took possession of a key domain name used by the intruders to control infected systems. In a Dec. 14 filing with the U.S. Securities and Exchange Commission, SolarWinds said roughly 33,000 of its more than 300,000 customers were Orion customers, and that fewer than 18,000 customers may have had an installation of the Orion product that contained the malicious code.
Microsoft has announced today that Microsoft Defender will begin quarantining compromised SolarWind Orion binaries starting tomorrow morning. The threat actors used these malicious binaries to install a backdoor known as Solorigate or SUNBURST. While Microsoft is already detecting the backdoor, they have not quarantined the SolarWinds binaries as it could affect essential network management operations used by customers.
The enterprise monitoring software provider which found itself at the epicenter of the most consequential supply chain attacks, said as many as 18,000 of its high-profile customers might have installed a tainted version of its Orion products. The company also reiterated in its security advisory that besides 2019.4 HF 5 and 2020.2 versions of SolarWinds Orion Platform, no other versions of the monitoring software or other non-Orion products were impacted by the vulnerability.
As the debris from the explosive SolarWinds hack continues to fly, it has been a busy 48 hours as everyone scrambles to find out if, like various US government bodies, they've been caught in the blast. Fast forward to the weekend, and various US government organizations discovered they too had been hacked, with Russia's APT29 aka Cozy Bear team suspected by officials.
SolarWinds' investigation into the recent attacks that leveraged its products to target government and private sector organizations revealed that 18,000 customers may have used the compromised products, the company said in a filing with the Securities and Exchange Commission on Monday. The vendor says the attacker could have exploited the introduced vulnerability to compromise the server running the Orion product.
Concern is gathering over the effects of the backdoor inserted into SolarWinds' network monitoring software on Britain's public sector - as tight-lipped government departments refuse to say whether UK institutions were accessed by Russian spies. Research by The Register has shown that SolarWinds' Orion is used widely across the British public sector, ranging from the Home Office and Ministry of Defence through NHS hospitals and trusts, right down to local city councils.
Communications at the U.S. Treasury and Commerce Departments were reportedly compromised by a supply chain attack on SolarWinds, a security vendor that helps the federal government and a range of Fortune 500 companies monitor the health of their IT networks. In a security advisory, Austin, Texas based SolarWinds acknowledged its systems "Experienced a highly sophisticated, manual supply chain attack on SolarWinds Orion Platform software builds for versions 2019.4 HF 5 through 2020.2.1, released between March 2020 and June 2020.".
A "Highly sophisticated" hacking group has breached the U.S. Treasury Department, the U.S. Department of Commerce's National Telecommunications and Information Administration, other government agencies and private sector companies via compromised SolarWinds Orion software. "Although we do not know how the backdoor code made it into the library, from the recent campaigns, research indicates that the attackers might have compromised internal build or distribution systems of SolarWinds," Microsoft noted, and added that the backdoor was distributed via automatic update platforms or systems in target networks.
Trojanized versions of SolarWinds' Orion IT monitoring and management software have been used in a supply chain attack leading to the breach of government and high-profile companies after attackers deployed a backdoor dubbed SUNBURST or Solorigate. SolarWinds' customer listing [1, 2] includes over 425 of the US Fortune 500, all top ten US telecom companies, hundreds of universities and colleges, all five branches of the US Military, the US Pentagon, the State Department, NASA, NSA, Postal Service, NOAA, Department of Justice, and the Office of the President of the United States.
The motive and the full scope of what intelligence was compromised remains unclear, but signs are that adversaries tampered with a software update released by Texas-based IT infrastructure provider SolarWinds earlier this year to infiltrate the systems of government agencies as well as FireEye and mount a highly-sophisticated supply chain attack. "The compromise of SolarWinds' Orion Network Management Products poses unacceptable risks to the security of federal networks," said Brandon Wales, acting director of the US Cybersecurity and Infrastructure Security Agency, which has released an emergency directive, urging federal civilian agencies to review their networks for suspicious activity and disconnect or power down SolarWinds Orion products immediately.
