A number of Twitter users have been forced to reset their passwords after a phishing attack.
Scottish blogger Andrew Girdwood was among those who reported receiving a message that states 'Due to concern that your account may have been compromised in a phishing attack that took place off-Twitter, your password was reset. Please create a new password by opening this link in your browser. ... Remember to choose a strong password that is a combination of letters, numbers, and symbols. Do not reuse your old password'.
Twitter acknowledged the password reset, describing it as a "precautionary step" but did not say how many users were affected or describe the nature of the phishing attack.
Twitter's official 'safety' account issued a tweet saying 'Got an email from us saying we've reset your password? A small # of accts seemed possibly affected offsite & we took a precautionary step'.
Previous tweets from this account offer advice for avoiding attacks, such as 'Giving out your username & password to a 3rd party site promising you more followers: not a good idea AND a violation of the Twitter Rules'.
Twitter's message to users urged them to remove any updates they did not post themselves; scan their computers for viruses and malware; and check the Twitter connections page and revoke access privileges for any third-party applications they do not recognise.
Twitter has become a magnet for computer hackers because of its increasing popularity, with reports of malware and spam on social networks rising 70 percent in the last 12 months.
