A link to a list claiming to hold four million Gmail addresses and passwords appeared Monday on popular tech startup forum Hacker News, and was tweeted out by the automated Twitter handle of the forum.
It is unclear whether the list contains current or correctly matched emails and passwords. Some comments on Hacker News point out discrepancies in the data.
"Indeed... My email is listed here, but it shows 'password' as its password, which is completely false. I only use 'password' in random websites that force me to register (but that I'll never visit again)," posted one forum member, who was responding to the link.
"This is from 2014 and likely not a Google hack or leak but a subset of credentials revealed by hacks or leaks from other sites," another user commented. It appeared the user was referring to a leak of Gmail usernames and passwords in 2014.
In 2014, a list of five million combinations of Gmail addresses and passwords surfaced online. Mashable reported most passwords appeared to be old and did not appear to belong to actual Gmail accounts.
Rik Lomas, who created the Twitter account for Hacker News, removed the tweet. He explained that the account is automated.
"It's a script that runs once an hour to grab new stories from https://news.ycombinator.com/ - it gets the top 5 stories, looks for ones that haven't been tweeted previously then tweets those ones," he told Inc. by Twitter direct message. "It's something I wrote in 2008 and keeps on running! I hardly ever touch it."
Lomas, who is founder and CEO of coding school SuperHi, confirmed that he has no affiliation with accelerator Y Combinator. The Twitter handle operates on its own, though the forum it pulls from is affiliated with the accelerator.
Inc. has reached out to Google for comment and will update this post with any response.
