Almost 5 million usernames and passwords purportedly for Google accounts were uploaded to a Russian online forum by hackers late Tuesday.
The International Business Times reports that data for 4.93 million Google accounts of English-, Spanish- and Russian-speaking users was leaked and published on a Russian-language Bitcoin security online forum. The posters said about 60% of the accounts were active.
In a statement sent to TIME, Google said it had "no evidence that our systems have been compromised."
"The security of our users' information is a top priority for us," the statement reads. The company said that whenever it is alerted that accounts may have been compromised, "we take steps to help those users secure their accounts." Email users are encouraged to utilize two-step verification when logging into accounts, as well as to create strong passwords.
According to Russian news service RIA Novosti, this leak followed another large hack of Russian email accounts. Several million accounts of Russia-based email services were also posted in a Bitcoin security forum.
