Hackers gained access to Mimecast’s systems via a poisoned SolarWind’s software update late last year. The attackers accessed and downloaded at least some of its source code repositories, email addresses, contact information and hashed, salted credentials belonging to some customers. The source code theft is limited in scope and unlikely to have any negative consequences for customers, Mimecasts says. The attack did not stop with the initial target, Confluera CEO John Morgan says. MimeCast recommends all of its customers reset server connection credentials being used on the MIMEcast platform.”]
