Cylance clarifies data breach details, except where the data came from

BlackBerry-owned Cylance says it is investigating a claim that a database containing customer, partner, and employee names, email addresses, and marketing data (allegedly 34 million records) is being sold on the dark web; the company maintains its systems and customer data appear secure and says the data likely came from a third-party marketing platform. The article links the listing to broader Snowflake-related breaches (Mandiant reports ~165 victims) and notes infostealer activity and credential reuse as contributing factors, but there is no confirmed compromise of Cylance customer systems.
