We are informing users out of an abundance of caution.” reads the official statement from the company.

“We have no evidence that any data has been made publicly available.”

In October, the Czech police, working with the FBI, arrested a Russian man at a hotel in Prague that is suspected to be involved in the 2012 LinkedIn hack.

The cascading effects of the 2012 LinkedIn breach are still being felt throughout the business world.  In June, CERT-Bund, Germany’s Computer Emergency Response Team for federal agencies, released a warning that corporate executives may be being targeted with malicious emails using information likely gained by hackers as a result of the 2012 breach.

CERT-Bund released a screenshot via its twitter feed, of an email containing a fake invoice targeting a business executive at an undisclosed organization.

In November, researchers from Heimdal Security reported a recent LinkedIn phishing campaign aiming to collect confidential information from unsuspecting users.
