The phishing scam has started to target Twitter users for their Twitter passwords. People have reported about getting emails from ‘Twitter’ asking you to imput your credentials.
Here is what Twitter have to say about it:
If you receive an email notice saying you’ve received a Direct Message with a link that redirects to what seems like Twitter.com, be careful about entering your Twitter credentials. Instead, look closely at the URL to see if it’s not really Twitter but a sketchy phishing site like http://twitter.access-logins.com. If this has you feeling a bit weirded out, feel free to change your Twitter password.
