Google has warned Gmail users that millions of email users are being targeted after hacks gained access to one of their huge databases.

Around 2.5 billion people use Gmail and Google Cloud.

Now those users have been put on alert suspicious activity and to take appropriate security action to secure their email accounts.

The attacks stem from a breach of Salesforce’s cloud platform that exposed users of Google services to further intrusions.

Google’s Threat Intelligence Group first warned of the attacks in June, revealing that threat actors were targeting people through social engineering attacks that involved impersonating IT support staff.

In August, Google confirmed that there had been a number of “successful intrusions” as a result of compromised passwords.

The data breach exposed information that was “basic and largely publicly available business information”, but it was being used to conduct more serious attacks.

However, Google warned that the group may up the threat by launching a data leak site.
