Twitter users are being targeted by another phishing campaign, according to Webroot malware researcher Andrew Brandt.
Users of the social network are receiving tweets containing short URLs, prefaced with the message "This you???" that lead to a fake Twitter login page, he said in a blog post.
The fake login page is hosted on a domain that points to a server in China that has been previously connected to spam campaigns selling cheap pharmaceuticals.
"It appears a lot of people may get tripped up in the rush to see what the link is all about," said Brandt.
Twitter users should look at the address bar before entering any credentials and avoid any URL that does not point to Twitter.com, he said.
The warning comes within days of other phishing attacks designed to steal Twitter passwords and use hijacked accounts to spread money-making spam campaigns.
