Back in December, the SolarWinds supply chain attack made the headlines when a Russian cyber espionage group tampered with updates for SolarWinds’ Orion Network Management products that the IT company provides to government agencies, military, and intelligence offices.
Mimecast was one of SolarWinds customers that were impacted by the attack, its systems were infected with the Sunburst backdoor distributed through tainted Orion software updates.
Now the company admitted that hackers stole part of its source code from its repositories, but did not modified it.
Mimecast also added that the source code accessed by the hackers was incomplete and would be used to build and run any component of the Mimecast service.
