The US Senate is questioning SolarWinds and other tech firms in a hearing Tuesday after unknown attackers, with suspected links to Russia, infiltrated the company’s software last year, compromising thousands of organizations including major federal agencies.

SolarWinds is joined in the hearing by FireEye, a cybersecurity firm that first discovered the malware in December, as well as Microsoft, whose president, Brad Smith, will be present in the proceedings. CrowdStrike CEO George Kurtz will also testify; his cybersecurity firm was apparently able to stave off the hackers.

The cyberattack began in March of last year and went undetected for months. SolarWinds told the SEC that about 18,000 of its 300,000 clients were targeted in the attack. High-level government data was left exposed — the Trump administration confirmed in December that hackers had indeed infiltrated key networks, including the US Treasury and the Commerce Department.

Fortune 500 companies — including Microsoft, AT&T, and McDonald’s — were among SolarWinds’ vulnerable customer base. Microsoft has said its products, including its Office 365 suite and Azure cloud, were not used in the hack, but they were targeted. And FireEye researchers say the hackers appear to be able to send emails and access calendars on Microsoft’s 365 suite.

The White House has said it may respond to the SolarWinds hacks in a matter of weeks.

As Insider reported, Tuesday’s hearing will be a pivotal moment in the relationship between the US government and the cybersecurity world, namely how the industry can help federal officials stave off nation-state attacks in the future.
