Online learning company, a subsidiary of LinkedIn, which is now officially a subsidiary of Microsoft, today sent out an email to some users alerting them to a breach of a database that includes contact information and courses some users viewed. Altogether, it’s emailing about 9.5 million users whose passwords weren’t included in the affected database, a LinkedIn spokesperson told VentureBeat in an email.

But there was a small percentage of users (fewer than 55,000) whose passwords were in the breached database, and has reset their passwords and informed them that it has done so. The passwords were “cryptographically salted and hashed” and no credit card information was included, the spokesperson wrote.

“We have no evidence that any of this data has been made publicly available and we have taken additional steps to secure accounts,” the spokesperson wrote.

The incident comes a few days after Yahoo disclosed a hack of data affecting more than 1 billion user accounts. But the LinkedIn spokesperson noted that the two incidents were not related.
