A phishing attack on Twitter has claimed several high-profile victims including a British cabinet minister and a bank.
Ed Miliband, the U.K's Secretary for Energy and Climate Change, on Friday found his Twitter account sending out spam tweets promoting sexual enhancement products.
U.K.-based security company Sophos says that Miliband appears to have been duped into revealing his login and account details by a series of attacks identified earlier this week.
The attack relies on the phrases "This You????" or "LOL this is funny" to get Twitter users to click on phishing links.
Those links take victims to a look-alike Twitter login page that turns entered information over to the cybercriminals behind the campaign.
Twitter on Wednesday posted a warning about this particular scam. "If you receive a DM or see a message with a phrase like 'This you??' or 'LOL is this you' followed by a link, please do not click through; there's a phishing site on the other side," the company said on its status page.
First Direct, an Internet and telephone banking subsidiary of HSBC Bank, on Friday acknowledged being victimized in a Twitter post: "Hi all, I'm sure you can tell, but we were hacked last night - please disregard any inappropriate tweets that purport to come from us!"
Recognizing the potential brand damage, the bank quickly clarified that only its Twitter account had been compromised and that no customer personal data had been revealed.
Other victims in the U.K. reportedly include Labour party deputy leader Harriet Harman and journalists from the BBC and The Guardian.
F-Secure, a security company based in Helsinki, Finland, attributes spammers' interest in compromised Twitter accounts to recent efforts by Google, Microsoft, and Yahoo to integrate nearly real-time data, like Twitter posts, into search results lists. This allows spammers to use Twitter and other social communication tools to target keywords associated with current news events, in order to secure prominent placement for their malicious links.
