Twitter is a famous social networking and information sharing service that allows users to exchange messages with very limited characters. When Twitter users want to share a URL with friends via tweets, they usually use URL shortening services to reduce the URL length since tweets can contain only a restricted number of characters. Owing to the popularity of Twitter, malicious users often try to find a way to attack it. The most common forms of Web attacks, including spam, scam, phishing and malware distribution attacks have also appeared on Twitter. Because tweets are short in length, attackers use shortened malicious URLs that redirect Twitter users to external attack servers.
