If the user clicks the link, they are taken to a bogus Facebook page where they are prompted to submit their Twitter login details. However, if the user enters their credentials, the malware will hijack their account in order to send the same malicious message to all of their contacts.
Then, the user is taken to a website that displays a fake YouTube video set against a fake Facebook background. This time, the victim is asked to update a ‘YouTube player’ to watch the video. As is usual in this type of scam, if the user clicks on the ‘Install’ button, they will find themselves downloading the Koobface.LP worm, which will infect their computer and steal all of their personal data.
“This attack exploits the two most popular social networking sites, Facebook and Twitter, to trick users into believing they are viewing a trusted site”, said Luis Corrons, technical director of PandaLabs. “It also relies on its victims’ curiosity by using a scandalous story involving U.S. President Barack Obama and racism. Cyber-criminals know people are curious by nature and take advantage of this to trick users and infect them with their creations.”
Twitter Direct Messages, Yet Another Technique to Spread Malware Infections
This is just the latest example of a cyber-scam that uses Twitter direct messages to spread. Users’ accounts receive dozens of them every day, with malicious links and enticing messages like: “What exactly do you think you're doing on this video clip”, “Hello this guy is saying bad rumors about u...”, “Did you see this pic of you?”, etc. “
Never, ever, click the links within the text of those messages as they could infect your computer”, explained Corrons. “Every time you receive a direct message you should check with the sender that they have knowingly sent it to you. Make sure it has not been automatically forwarded to you from a hacked account. As a general rule, always keep your antivirus software up to date and be wary of messages offering sensational videos or unusual stories as, in 99 percent of cases they are designed to compromise user security.”

Since 1990, PandaLabs, Panda Security’s malware research laboratory, has been working to detect and classify malware in order to protect consumers and companies against new Internet threats. To do so, PandaLabs uses Collective Intelligence, a cloud-based proprietary system that leverages the knowledge gathered from Panda’s user community to automatically detect, analyse and classify the more than 73,000 new malware strains that appear every day. This automated malware classification is complemented through the work of an international team with researchers specialized each in a specific type of malware (viruses, worms, Trojans, spyware and other attacks) to provide global coverage.
