Silicon Republic has reported that Gmail has been affected by a massive email and password leak. The website says 5 million accounts appeared to have been compromised, but questions remain over the actual threat to users. “On the Reddit subreddit ‘netsec’, a user has posted a link supposedly showing all of the affected email names and passwords of users, many of which appear to be months, if not years, old.” the report said. According to Freedom Hacker, the original .txt file of Gmail usernames have been posted to a Russian bitcoin forum but now Gmail users who might be concerned their password may have been included are being warned not to enter their passwords into websites to check if theirs is secure. The report said since the file being released, a number of malicious phising sites have popped up, offering to check whether someone’s email has been hacked by asking them to provide their addresses. The origin of the leak is still unknown.
