A backdoored binary that was said to have allowed compromises of companies in a number of countries is still present on the site of American vendor SolarWinds, a tech researcher says.

Andrew Morris, the founder of Grey Noise Intelligence, said in a tweet that he had just downloaded "the infected installer from the SolarWinds website and extracted the installer/various CABs and found that the backdoor'd DLL is definitely still contained in the installer on the website literally right now".

Morris is the second person to note that SolarWinds has not removed the malicious DLL from its site.

Earlier, Kyle Hanslovan, the chief executive of Huntress Labs, another security firm, tweeted that SolarWinds had yet to revoke the digital certificate it had used to sign the backdoored DLL.

He also provided a screenshot of the malicious software sitting on the SolarWinds site. A directory listing that he also linked to showed clearly that the compromised component, which was named as SolarWinds.Orion.Core.BusinessLayer.dll, a digitally signed part of the Orion network management software owned by the firm, was still present.

This contained a backdoor that communicated with third-party servers using HTTP.

On Monday AEDT, security firm FireEye, which last week said it had suffered a breach and lost its attack tools, said it had identified a global campaign to compromise public and private sector bodies through corruption of software supply chains, using software that runs on Windows.

Chief executive Kevin Mandia said the compromise was executed through the Orion network monitoring product sold by SolarWinds.

Hanslovan wrote: "The full compromised package is still being hosted online as well", and highlighted the compromised binary.

Vinoth Kumar, who describes himself as a part-time bounty hunter who had pointed to another security lapse linked to SolarWinds, retweeted Hanslovan's tweet, adding, "And they still had the malicious binaries on the download portal until today."
